However, CCTV systems do not use one universal cable type. The correct construction depends on whether the system uses analogue video, HD-over-coax, IP networking or an optical backbone.<\/p>\n\n\n\n<p id=\"wd-ded14285\" class=\"wp-block-wd-paragraph\">For example, traditional and compatible HD-over-coax cameras often use 75-ohm coaxial cable. Some surveillance systems combine coaxial video with additional low-voltage signal conductors in one composite construction. By contrast, IP cameras normally use Ethernet cabling such as Cat 5e or Cat 6. Many IP cameras can also receive power through Power over Ethernet (PoE).<\/p>\n\n\n\n<p id=\"wd-1e2f8a7d\" class=\"wp-block-wd-paragraph\">Fiber optic cable serves a different role. It becomes valuable when surveillance networks cover long distances, multiple buildings or electrically noisy environments. However, standard optical fiber does not power the camera. Therefore, the project must provide another power method where required.<\/p>\n\n\n\n<p id=\"wd-d65c8c53\" class=\"wp-block-wd-paragraph\">As a result, CCTV cabling should be selected from the complete system architecture. Engineers need to consider signal type, route length, bandwidth, power, attenuation, electromagnetic interference, outdoor exposure and mechanical risk.<\/p>\n\n\n\n<p id=\"wd-5a3956c7\" class=\"wp-block-wd-paragraph\">ETK Kablo manufactures a dedicated <a href=\"\/en\/product-cat\/cctv-cables\/\">surveillance product portfolio<\/a> together with coaxial, Data\/LAN and fiber optic solutions for different security-system architectures.<\/p>\n\n\n\n<p id=\"wd-c139f056\" class=\"wp-block-wd-paragraph\"><strong>Quick answer:<\/strong> Use a compatible 75-ohm coaxial cable for analogue or HD-over-coax systems. Choose a composite surveillance construction when one cable needs video plus additional low-voltage signal conductors. Use Cat 5e or Cat 6 for many IP camera links. For long-distance or multi-building backbones, fiber optic cable can connect remote network switches and surveillance zones.<\/p>\n\n\n\n<h2 id=\"wd-45fe38f9\" class=\"wp-block-wd-title title\">What Is a CCTV Cable?<\/h2>\n\n\n\n<p id=\"wd-fa96aecd\" class=\"wp-block-wd-paragraph\">A CCTV cable provides the physical connection between components of a closed-circuit television system.<\/p>\n\n\n\n<p id=\"wd-894ded7f\" class=\"wp-block-wd-paragraph\">Depending on the system architecture, the cabling can carry:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Analogue video<\/li>\n\n\n\n<li>Compatible HD-over-coax video<\/li>\n\n\n\n<li>Ethernet data<\/li>\n\n\n\n<li>PoE power<\/li>\n\n\n\n<li>Low-voltage auxiliary signals<\/li>\n\n\n\n<li>Control or communication circuits<\/li>\n\n\n\n<li>Backbone traffic between network switches<\/li>\n<\/ul>\n\n\n\n<p id=\"wd-879e6253\" class=\"wp-block-wd-paragraph\">However, one cable does not necessarily carry all these functions.<\/p>\n\n\n\n<p id=\"wd-c90ae88d\" class=\"wp-block-wd-paragraph\">A standalone coaxial cable mainly carries the compatible video signal. Meanwhile, a composite construction can add low-voltage signal conductors around the coaxial element. An Ethernet cable carries digital network traffic and can also deliver PoE when the complete system supports it.<\/p>\n\n\n\n<p id=\"wd-5581bf29\" class=\"wp-block-wd-paragraph\">Therefore, the term describes an application family rather than one fixed electrical design.<\/p>\n\n\n\n<h2 id=\"wd-d448200b\" class=\"wp-block-wd-title title\">CCTV Cable Types Used in Surveillance Systems<\/h2>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th>Cable Type<\/th><th>Typical System<\/th><th>Main Function<\/th><\/tr><\/thead><tbody><tr><td>RG59 coaxial<\/td><td>Analogue \/ compatible HD-over-coax<\/td><td>Video signal<\/td><\/tr><tr><td>RG6 coaxial<\/td><td>Compatible video systems<\/td><td>Video signal where its electrical data match the route<\/td><\/tr><tr><td>Composite surveillance cable<\/td><td>Analogue \/ hybrid systems<\/td><td>Coaxial video plus additional low-voltage circuits<\/td><\/tr><tr><td>Cat 5e<\/td><td>IP CCTV<\/td><td>Ethernet data and compatible PoE<\/td><\/tr><tr><td>Cat 6<\/td><td>IP CCTV<\/td><td>Ethernet data and compatible PoE<\/td><\/tr><tr><td>Cat 6A<\/td><td>Higher-capacity network infrastructure<\/td><td>10 Gigabit structured-cabling capability where required<\/td><\/tr><tr><td>Fiber optic cable<\/td><td>Long-distance \/ campus surveillance<\/td><td>Optical network backbone<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>So, <strong>what is a CCTV cable<\/strong> in practical terms? It is the cable construction that matches the camera technology, transmission method and installation environment.<\/p>\n\n\n\n<p id=\"wd-db2e4153\" class=\"wp-block-wd-paragraph\">Each technology solves a different problem. Therefore, the camera and network architecture should come before the cable name.<\/p>\n\n\n\n<h2 id=\"wd-40d21374\" class=\"wp-block-wd-title title\">Analogue, HD-over-Coax and IP Camera Systems<\/h2>\n\n\n\n<h3 id=\"wd-d1eabaa1\" class=\"wp-block-wd-title title\">Analogue CCTV<\/h3>\n\n\n\n<p id=\"wd-adc9a334\" class=\"wp-block-wd-paragraph\">Traditional analogue cameras transmit video as an electrical signal. Compatible 75-ohm coaxial cable commonly connects the camera to a DVR or other video equipment.<\/p>\n\n\n\n<p id=\"wd-7c61295b\" class=\"wp-block-wd-paragraph\">For this reason, RG59 remains strongly associated with conventional surveillance video.<\/p>\n\n\n\n<h3 id=\"wd-a9fc8ff1\" class=\"wp-block-wd-title title\">HD-over-Coax<\/h3>\n\n\n\n<p id=\"wd-85eb3921\" class=\"wp-block-wd-paragraph\">Several modern surveillance technologies can transmit higher-resolution video while retaining coaxial infrastructure.<\/p>\n\n\n\n<p id=\"wd-83f77b91\" class=\"wp-block-wd-paragraph\">However, supported distance depends on the exact camera technology and equipment specification. Cable attenuation, connectors and installation quality also affect the link.<\/p>\n\n\n\n<p id=\"wd-2ba534ec\" class=\"wp-block-wd-paragraph\">Therefore, designers should not select RG59 or RG6 from a generic distance claim alone.<\/p>\n\n\n\n<h3 id=\"wd-9aa9cf0b\" class=\"wp-block-wd-title title\">IP CCTV<\/h3>\n\n\n\n<p id=\"wd-bd8d5ae8\" class=\"wp-block-wd-paragraph\">An IP camera operates as a network device. It sends digital video through Ethernet rather than through a conventional analogue-video circuit.<\/p>\n\n\n\n<p id=\"wd-2964bd18\" class=\"wp-block-wd-paragraph\">As a result, IP cameras commonly use Category-rated balanced copper cabling. PoE can also carry electrical power through the same network connection when the camera, switch and cabling support the required PoE level.<\/p>\n\n\n\n<p>For IP systems, understanding <strong>what is a CCTV cable<\/strong> also means understanding that standard Ethernet cabling becomes part of the surveillance infrastructure.<\/p>\n\n\n\n<h2 id=\"wd-2f6ee1b7\" class=\"wp-block-wd-title title\">Coaxial CCTV Cable: How It Works<\/h2>\n\n\n\n<p id=\"wd-77a1e015\" class=\"wp-block-wd-paragraph\">Coaxial cable uses a concentric electrical construction. A typical design contains a center conductor, dielectric insulation, metallic screen and outer jacket.<\/p>\n\n\n\n<p id=\"wd-05ca616c\" class=\"wp-block-wd-paragraph\">The geometry creates a controlled characteristic impedance. Many surveillance and video systems use a nominal 75-ohm architecture.<\/p>\n\n\n\n<p id=\"wd-b836aaec\" class=\"wp-block-wd-paragraph\">ETK Kablo manufactures a broad <a href=\"\/en\/product-cat\/coaxial-cables\/\">RG coaxial cable portfolio<\/a> with different conductors, dielectric systems and screen constructions.<\/p>\n\n\n\n<p id=\"wd-328cf191\" class=\"wp-block-wd-paragraph\">However, buyers should verify the exact product rather than assuming that every cable in one RG family has identical performance.<\/p>\n\n\n\n<h2 id=\"wd-ad4580f6\" class=\"wp-block-wd-title title\">Why 75-Ohm Impedance Matters<\/h2>\n\n\n\n<p id=\"wd-32d4ee1d\" class=\"wp-block-wd-paragraph\">Video transmission performs best when the cable and connected equipment use compatible characteristic impedance.<\/p>\n\n\n\n<p id=\"wd-ac3cb36c\" class=\"wp-block-wd-paragraph\">If the impedance does not match the system, reflections can reduce signal quality. Therefore, installers should not substitute a 50-ohm RF cable simply because its outside diameter looks similar.<\/p>\n\n\n\n<p id=\"wd-50094212\" class=\"wp-block-wd-paragraph\">In addition, the RG designation alone does not provide every electrical detail. Engineers should verify impedance, attenuation and capacitance from the applicable datasheet.<\/p>\n\n\n\n<h2 id=\"wd-cc782688\" class=\"wp-block-wd-title title\">RG59 for Surveillance Video<\/h2>\n\n\n\n<p id=\"wd-35597a7c\" class=\"wp-block-wd-paragraph\">RG59 is one of the best-known coaxial families for camera systems.<\/p>\n\n\n\n<p id=\"wd-b2f44c38\" class=\"wp-block-wd-paragraph\">It can provide a compact solution for compatible analogue and HD-over-coax links. In addition, installers benefit from a mature connector ecosystem.<\/p>\n\n\n\n<p id=\"wd-423f88c1\" class=\"wp-block-wd-paragraph\">However, there is no universal \u201cRG59 maximum distance.\u201d Actual performance depends on several factors:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Video technology<\/li>\n\n\n\n<li>Operating frequency<\/li>\n\n\n\n<li>Cable attenuation<\/li>\n\n\n\n<li>Conductor design<\/li>\n\n\n\n<li>Dielectric material<\/li>\n\n\n\n<li>Screen construction<\/li>\n\n\n\n<li>Connector losses<\/li>\n\n\n\n<li>Camera and recorder specifications<\/li>\n<\/ul>\n\n\n\n<p id=\"wd-b26a3f72\" class=\"wp-block-wd-paragraph\">Therefore, the system manufacturer&#8217;s route limit and the cable&#8217;s actual attenuation data should guide the design.<\/p>\n\n\n\n<h2 id=\"wd-81fc8a76\" class=\"wp-block-wd-title title\">RG6 vs RG59<\/h2>\n\n\n\n<p id=\"wd-68978c46\" class=\"wp-block-wd-paragraph\">RG6 and RG59 can both appear in compatible 75-ohm video systems. However, their physical and electrical constructions normally differ.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th>Characteristic<\/th><th>RG59<\/th><th>RG6<\/th><\/tr><\/thead><tbody><tr><td>General cable size<\/td><td>Usually more compact<\/td><td>Usually larger<\/td><\/tr><tr><td>Common application direction<\/td><td>CCTV and video<\/td><td>Video, CATV, satellite and broadband<\/td><\/tr><tr><td>Attenuation<\/td><td>Check the exact product and frequency<\/td><td>Check the exact product and frequency<\/td><\/tr><tr><td>Characteristic impedance<\/td><td>Verify the exact product<\/td><td>Verify the exact product<\/td><\/tr><tr><td>Selection method<\/td><td>Use equipment and cable data<\/td><td>Use equipment and cable data<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p id=\"wd-1aebdba4\" class=\"wp-block-wd-paragraph\">RG6 is not automatically better than RG59. Likewise, RG59 does not have one fixed maximum route length. Instead, compare the actual electrical performance against the surveillance equipment requirement.<\/p>\n\n\n\n<h2 id=\"wd-edb60f88\" class=\"wp-block-wd-title title\">Composite CCTV Cable<\/h2>\n\n\n\n<p id=\"wd-d35c057f\" class=\"wp-block-wd-paragraph\">A composite construction places more than one circuit type inside a common outer cable.<\/p>\n\n\n\n<p id=\"wd-4b305b19\" class=\"wp-block-wd-paragraph\">ETK Kablo&#8217;s <a href=\"\/en\/product\/cctv-1-coax\/\">composite surveillance product<\/a> combines one 75-ohm coaxial video element with additional 0.22 mm\u00b2 stranded copper signal conductors. The coaxial element uses a 7 \u00d7 0.20 mm stranded copper center conductor, solid polyethylene dielectric and electrolytic copper braid.<\/p>\n\n\n\n<p id=\"wd-a1d9cd24\" class=\"wp-block-wd-paragraph\">This architecture can reduce the number of separate cables along the route. In addition, it can simplify installations that require coaxial video and auxiliary low-voltage circuits.<\/p>\n\n\n\n<p id=\"wd-0b78699c\" class=\"wp-block-wd-paragraph\">However, the additional conductors should not automatically be treated as camera-power conductors. Their cross-section and the camera&#8217;s electrical demand must match before the project uses them for power.<\/p>\n\n\n\n<p>Therefore, when buyers ask <strong>what is a CCTV cable<\/strong> for a hybrid analogue system, the answer can include both the coaxial video element and the required auxiliary conductors.<\/p>\n\n\n\n<h2 id=\"wd-c112e09f\" class=\"wp-block-wd-title title\">Standalone Coaxial vs Composite Construction<\/h2>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th>Feature<\/th><th>Standalone Coaxial<\/th><th>Composite Construction<\/th><\/tr><\/thead><tbody><tr><td>Main role<\/td><td>Compatible video or RF transmission<\/td><td>Video plus additional low-voltage circuits<\/td><\/tr><tr><td>Additional conductors<\/td><td>Not part of the standard coaxial element<\/td><td>Included according to product design<\/td><\/tr><tr><td>Installation<\/td><td>Separate circuits may need separate cables<\/td><td>Can reduce the number of cable runs<\/td><\/tr><tr><td>Selection basis<\/td><td>Impedance, attenuation, frequency<\/td><td>Video plus auxiliary-circuit requirements<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p id=\"wd-80c635ac\" class=\"wp-block-wd-paragraph\">Consequently, the system design should determine whether a standalone coaxial cable or a composite construction offers the better installation strategy.<\/p>\n\n\n\n<h2 id=\"wd-2f9f80fc\" class=\"wp-block-wd-title title\">CCTV Cable for IP Cameras<\/h2>\n\n\n\n<p id=\"wd-cb4257bc\" class=\"wp-block-wd-paragraph\">IP surveillance changes the cable-selection logic because each camera becomes part of the data network.<\/p>\n\n\n\n<p id=\"wd-69042337\" class=\"wp-block-wd-paragraph\">Typical copper options include Cat 5e, Cat 6 and, in some infrastructure layers, Cat 6A.<\/p>\n\n\n\n<p id=\"wd-1c49d634\" class=\"wp-block-wd-paragraph\">In addition, the complete network can use fiber between buildings, remote switches or major aggregation points.<\/p>\n\n\n\n<p id=\"wd-4184f6ba\" class=\"wp-block-wd-paragraph\">For a broader explanation of balanced copper network cabling, see our <a href=\"\/en\/blog\/what-is-a-data-lan-cable\/\">LAN cable selection guide<\/a>.<\/p>\n\n\n\n<h2 id=\"wd-f6591d4f\" class=\"wp-block-wd-title title\">Cat 5e for IP Cameras<\/h2>\n\n\n\n<p id=\"wd-6e85643f\" class=\"wp-block-wd-paragraph\">Cat 5e supports Gigabit Ethernet in compliant structured-cabling systems. Therefore, it provides sufficient network capacity for many individual IP cameras.<\/p>\n\n\n\n<p id=\"wd-c3358027\" class=\"wp-block-wd-paragraph\">ETK Kablo&#8217;s <a href=\"\/en\/product-cat\/data-lan-cables\/cat-5e-data-cable\/\">Category 5e range<\/a> includes different shielding and jacket constructions for indoor, outdoor and mechanically demanding routes.<\/p>\n\n\n\n<p id=\"wd-79f57051\" class=\"wp-block-wd-paragraph\">However, the category alone does not complete the specification. Engineers must also consider PoE, jacket material, electromagnetic environment and installation method.<\/p>\n\n\n\n<h2 id=\"wd-312adbe1\" class=\"wp-block-wd-title title\">Cat 6 for IP Cameras<\/h2>\n\n\n\n<p id=\"wd-8e524702\" class=\"wp-block-wd-paragraph\">Cat 6 offers more transmission margin than Cat 5e and operates through a higher standardized frequency range.<\/p>\n\n\n\n<p id=\"wd-d05912e9\" class=\"wp-block-wd-paragraph\">As a result, many new surveillance projects choose Cat 6 for their access network.<\/p>\n\n\n\n<p id=\"wd-8a8e7e02\" class=\"wp-block-wd-paragraph\">ETK Kablo&#8217;s <a href=\"\/en\/product-cat\/data-lan-cables\/cat-6-data-cable\/\">Category 6 range<\/a> includes unshielded, screened, outdoor, aerial and mechanically protected options.<\/p>\n\n\n\n<p id=\"wd-0859a3bc\" class=\"wp-block-wd-paragraph\">Nevertheless, Cat 6 does not automatically improve camera image quality. If the network already carries the required video stream without congestion or errors, the camera and encoding system determine the image quality.<\/p>\n\n\n\n<h2 id=\"wd-eb0b75a8\" class=\"wp-block-wd-title title\">When Does Cat 6A Make Sense?<\/h2>\n\n\n\n<p id=\"wd-7688a67e\" class=\"wp-block-wd-paragraph\">Most individual IP cameras do not need a 10 Gigabit Ethernet connection.<\/p>\n\n\n\n<p id=\"wd-7a1944fa\" class=\"wp-block-wd-paragraph\">However, Cat 6A can make sense in larger structured-cabling systems. For example, the project may use it in control rooms, multi-service networks or other links where 10GBASE-T capability supports the broader infrastructure strategy.<\/p>\n\n\n\n<p id=\"wd-3f1c0abf\" class=\"wp-block-wd-paragraph\">Therefore, designers should choose Cat 6A because of the network architecture rather than camera resolution alone.<\/p>\n\n\n\n<h2 id=\"wd-e3d0ee71\" class=\"wp-block-wd-title title\">Power over Ethernet and Camera Cabling<\/h2>\n\n\n\n<p id=\"wd-f0259f16\" class=\"wp-block-wd-paragraph\">PoE allows compatible network equipment to deliver data and electrical power through the same balanced copper connection.<\/p>\n\n\n\n<p id=\"wd-d292b13a\" class=\"wp-block-wd-paragraph\">This approach simplifies many IP camera installations. For example, one horizontal cable can connect the camera to a PoE-capable network switch.<\/p>\n\n\n\n<p id=\"wd-cb71c78b\" class=\"wp-block-wd-paragraph\">However, PoE adds electrical and thermal considerations. Engineers should check:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Camera power demand<\/li>\n\n\n\n<li>PoE switch capability<\/li>\n\n\n\n<li>Conductor resistance<\/li>\n\n\n\n<li>Resistance unbalance<\/li>\n\n\n\n<li>Cable conductor size<\/li>\n\n\n\n<li>Bundle size<\/li>\n\n\n\n<li>Ambient temperature<\/li>\n\n\n\n<li>Pathway conditions<\/li>\n<\/ul>\n\n\n\n<p id=\"wd-c9f45b2e\" class=\"wp-block-wd-paragraph\">As PoE power increases, these factors become more important. Therefore, buyers should not assume that every Category cable behaves identically under power loading.<\/p>\n\n\n\n<h2 id=\"wd-bf75b069\" class=\"wp-block-wd-title title\">How Far Can an IP Camera Run on Copper Ethernet?<\/h2>\n\n\n\n<p id=\"wd-5d37f8bd\" class=\"wp-block-wd-paragraph\">Conventional balanced-copper Ethernet structured cabling normally uses a 100-meter channel architecture.<\/p>\n\n\n\n<p id=\"wd-f76f64ac\" class=\"wp-block-wd-paragraph\">A common design allows up to 90 meters of permanent-link installation cable, while patch and equipment cords complete the channel.<\/p>\n\n\n\n<p id=\"wd-1cd7ef6e\" class=\"wp-block-wd-paragraph\">Therefore, installers should not simply extend standard Cat 5e or Cat 6 for several hundred meters.<\/p>\n\n\n\n<p id=\"wd-e838e7b9\" class=\"wp-block-wd-paragraph\">For longer routes, designers can use an intermediate active device, a suitable extender or an optical backbone.<\/p>\n\n\n\n<h2 id=\"wd-6f98e532\" class=\"wp-block-wd-title title\">Fiber Optic Backbones for Surveillance<\/h2>\n\n\n\n<p id=\"wd-1cd4c1e7\" class=\"wp-block-wd-paragraph\">Fiber optic cable carries network traffic as light and becomes especially useful in large surveillance systems.<\/p>\n\n\n\n<p id=\"wd-56c396b7\" class=\"wp-block-wd-paragraph\">Key advantages include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Long transmission distance<\/li>\n\n\n\n<li>High backbone capacity<\/li>\n\n\n\n<li>Immunity to electromagnetic interference<\/li>\n\n\n\n<li>Electrical isolation with fully dielectric designs<\/li>\n\n\n\n<li>Efficient aggregation of many camera zones<\/li>\n<\/ul>\n\n\n\n<p id=\"wd-e5a1af22\" class=\"wp-block-wd-paragraph\">Typical projects include airports, industrial plants, railways, ports, stadiums, campuses and urban surveillance networks.<\/p>\n\n\n\n<p id=\"wd-373f6cc6\" class=\"wp-block-wd-paragraph\">For additional background, see our <a href=\"\/en\/blog\/what-is-a-fiber-optic-cable\/\">optical backbone guide<\/a>.<\/p>\n\n\n\n<p id=\"wd-13d3f541\" class=\"wp-block-wd-paragraph\">However, standard optical fiber does not deliver electrical power to the camera. Therefore, remote camera locations still need an appropriate power source.<\/p>\n\n\n\n<h2 id=\"wd-a69d1129\" class=\"wp-block-wd-title title\">When Should a Surveillance Network Use Fiber?<\/h2>\n\n\n\n<p id=\"wd-3147c74c\" class=\"wp-block-wd-paragraph\">Fiber becomes attractive when conventional copper Ethernet creates distance or environmental limitations.<\/p>\n\n\n\n<p id=\"wd-2166f351\" class=\"wp-block-wd-paragraph\">Consider an optical backbone when:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Camera zones sit beyond a normal copper Ethernet segment<\/li>\n\n\n\n<li>The system spans several buildings<\/li>\n\n\n\n<li>High electromagnetic interference exists<\/li>\n\n\n\n<li>Many cameras aggregate at remote network switches<\/li>\n\n\n\n<li>Electrical isolation matters<\/li>\n\n\n\n<li>Future backbone capacity is important<\/li>\n<\/ul>\n\n\n\n<p id=\"wd-2a9f541a\" class=\"wp-block-wd-paragraph\">For example, an industrial site can use short Cat 6 PoE links between local switches and cameras.

By contrast, F\/UTP or other screened constructions can add protection on electrically noisy routes.<\/p>\n\n\n\n<p id=\"wd-ab116ee4\" class=\"wp-block-wd-paragraph\">However, screened structured cabling also depends on correct termination and bonding.

Therefore, electrical performance alone should not determine the cable.<\/p>\n\n\n\n<h2 id=\"wd-d490d01e\" class=\"wp-block-wd-title title\">Outdoor Camera Routes<\/h2>\n\n\n\n<p id=\"wd-bfa35577\" class=\"wp-block-wd-paragraph\">Outdoor installations add environmental stress.<\/p>\n\n\n\n<p id=\"wd-76279ba2\" class=\"wp-block-wd-paragraph\">The route may face:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>UV radiation<\/li>\n\n\n\n<li>Rain and moisture<\/li>\n\n\n\n<li>Temperature variation<\/li>\n\n\n\n<li>Mechanical impact<\/li>\n\n\n\n<li>Rodents<\/li>\n\n\n\n<li>Long exposed sections<\/li>\n<\/ul>\n\n\n\n<p id=\"wd-21b512b8\" class=\"wp-block-wd-paragraph\">As a result, outdoor systems can require PE jackets, UV-resistant materials or additional mechanical protection.<\/p>\n\n\n\n<p id=\"wd-28779ecc\" class=\"wp-block-wd-paragraph\">However, an outdoor jacket does not automatically make a cable suitable for direct burial or aerial use. Those installation methods create additional mechanical requirements.<\/p>\n\n\n\n<h2 id=\"wd-fa279ad8\" class=\"wp-block-wd-title title\">Aerial Camera Networks<\/h2>\n\n\n\n<p id=\"wd-8bc71e8d\" class=\"wp-block-wd-paragraph\">Pole-mounted cameras can require aerial cable routes.<\/p>\n\n\n\n<p id=\"wd-5712e0fa\" class=\"wp-block-wd-paragraph\">In these cases, the designer must consider wind, span length, mechanical support and cable tension.<\/p>\n\n\n\n<p id=\"wd-51c02a12\" class=\"wp-block-wd-paragraph\">A standard indoor Ethernet cable should not carry its own aerial span simply because its electrical performance suits the camera.<\/p>\n\n\n\n<p id=\"wd-af2fb87a\" class=\"wp-block-wd-paragraph\">Instead, projects should use a purpose-designed aerial data construction or another supported pathway.<\/p>\n\n\n\n<h2 id=\"wd-f48be424\" class=\"wp-block-wd-title title\">Mechanical Protection and Armour<\/h2>\n\n\n\n<p id=\"wd-d7c560d5\" class=\"wp-block-wd-paragraph\">Some camera routes face significant physical risk.<\/p>\n\n\n\n<p id=\"wd-bd0d1f16\" class=\"wp-block-wd-paragraph\">Factories, tunnels, transport systems and outdoor infrastructure can expose cables to impact, crushing or maintenance activity.<\/p>\n\n\n\n<p id=\"wd-ff7cd14e\" class=\"wp-block-wd-paragraph\">In these cases, mechanical reinforcement can improve cable protection. Depending on the product family, the project can evaluate Steel Wire Armour, Steel Wire Braid or another suitable reinforcement system.<\/p>\n\n\n\n<p id=\"wd-7fbb6f69\" class=\"wp-block-wd-paragraph\">However, armour increases diameter, weight and stiffness. Therefore, specify it only where the route creates a real mechanical requirement.<\/p>\n\n\n\n<h2 id=\"wd-742beccf\" class=\"wp-block-wd-title title\">Coaxial Cable vs Dedicated Surveillance Construction<\/h2>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th>Characteristic<\/th><th>Standalone Coaxial<\/th><th>Dedicated Composite Construction<\/th><\/tr><\/thead><tbody><tr><td>Main architecture<\/td><td>One controlled-impedance coaxial element<\/td><td>Coaxial element plus additional conductors<\/td><\/tr><tr><td>Main selection criteria<\/td><td>Impedance, attenuation, frequency and shielding<\/td><td>Video requirement plus auxiliary circuits<\/td><\/tr><tr><td>Power \/ control conductors<\/td><td>Not inherently included<\/td><td>Can be included according to product design<\/td><\/tr><tr><td>Typical procurement logic<\/td><td>Select the exact RG construction<\/td><td>Define the complete surveillance-system requirement<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p id=\"wd-1d7818b0\" class=\"wp-block-wd-paragraph\">This distinction prevents a common purchasing error.

The cable itself still follows its Category transmission requirements.<\/p>\n\n\n\n<p id=\"wd-22e97703\" class=\"wp-block-wd-paragraph\">For example, a Cat 6 cable can connect a workstation in one project and an IP camera in another.<\/p>\n\n\n\n<p id=\"wd-778a6130\" class=\"wp-block-wd-paragraph\">However, camera projects can add requirements for PoE, outdoor exposure, shielding, LSZH materials, aerial installation or mechanical protection.<\/p>\n\n\n\n<p id=\"wd-0ff1f242\" class=\"wp-block-wd-paragraph\">ETK Kablo&#8217;s broader <a href=\"\/en\/product-cat\/data-lan-cables\/\">network cabling portfolio<\/a> covers these structured-cabling choices.<\/p>\n\n\n\n<h2 id=\"wd-16cb1092\" class=\"wp-block-wd-title title\">Device Interoperability and ONVIF<\/h2>\n\n\n\n<p id=\"wd-caa176c7\" class=\"wp-block-wd-paragraph\">Cabling and device interoperability solve different parts of an IP surveillance system.<\/p>\n\n\n\n<p id=\"wd-52dcb6dc\" class=\"wp-block-wd-paragraph\">ONVIF develops standardized interfaces for IP-based physical security products.

The physical network still needs suitable Ethernet or fiber infrastructure.<\/p>\n\n\n\n<h2 id=\"wd-33f977c9\" class=\"wp-block-wd-title title\">How to Choose the Right CCTV Cable<\/h2>\n\n\n\n<p>To determine <strong>what is a CCTV cable<\/strong> for a specific project, start with the camera technology and work outward to distance, power and installation conditions.<\/p>\n\n\n\n<h3 id=\"wd-19138739\" class=\"wp-block-wd-title title\">1. Identify the Camera Technology<\/h3>\n\n\n\n<p id=\"wd-6741e8ef\" class=\"wp-block-wd-paragraph\">First, determine whether the system uses analogue, HD-over-coax or IP cameras.<\/p>\n\n\n\n<h3 id=\"wd-d9ab19d2\" class=\"wp-block-wd-title title\">2. Define the Signal Interface<\/h3>\n\n\n\n<p id=\"wd-07798044\" class=\"wp-block-wd-paragraph\">For coaxial systems, confirm the required impedance and video technology. For IP systems, define the Ethernet category and network architecture.<\/p>\n\n\n\n<h3 id=\"wd-01ebf2b3\" class=\"wp-block-wd-title title\">3. Calculate the Route Length<\/h3>\n\n\n\n<p id=\"wd-f515f8b1\" class=\"wp-block-wd-paragraph\">Next, measure the actual cable route. Do not rely on generic RG59 or RG6 distance claims. Likewise, respect the normal Ethernet channel architecture.<\/p>\n\n\n\n<h3 id=\"wd-0dd71aa7\" class=\"wp-block-wd-title title\">4. Define the Power Method<\/h3>\n\n\n\n<p id=\"wd-bb2a5ffc\" class=\"wp-block-wd-paragraph\">Determine whether the camera uses local power, a separate electrical circuit, suitable auxiliary conductors or PoE.<\/p>\n\n\n\n<h3 id=\"wd-934b9d87\" class=\"wp-block-wd-title title\">5. Review Bandwidth<\/h3>\n\n\n\n<p id=\"wd-8c1a6b3f\" class=\"wp-block-wd-paragraph\">For IP systems, calculate camera bitrate and aggregate traffic. Then verify the access and backbone capacity.<\/p>\n\n\n\n<h3 id=\"wd-79f10e36\" class=\"wp-block-wd-title title\">6. Evaluate EMI<\/h3>\n\n\n\n<p id=\"wd-bff2f84e\" class=\"wp-block-wd-paragraph\">Check motors, drives, switchgear and nearby power cables. Then select shielding only where the environment requires it.<\/p>\n\n\n\n<h3 id=\"wd-dcc12588\" class=\"wp-block-wd-title title\">7. Define the Environment<\/h3>\n\n\n\n<p id=\"wd-139cda3c\" class=\"wp-block-wd-paragraph\">Specify indoor, outdoor, aerial, underground or mechanically exposed installation.<\/p>\n\n\n\n<h3 id=\"wd-2a250cc5\" class=\"wp-block-wd-title title\">8. Select the Jacket and Mechanical Protection<\/h3>\n\n\n\n<p id=\"wd-2dd6c2df\" class=\"wp-block-wd-paragraph\">Choose PVC, LSZH, PE or another appropriate jacket according to the route. Add reinforcement only when the project needs it.<\/p>\n\n\n\n<h3 id=\"wd-c1f87b3d\" class=\"wp-block-wd-title title\">9. Verify Connectors and Equipment<\/h3>\n\n\n\n<p id=\"wd-8f949fc1\" class=\"wp-block-wd-paragraph\">Confirm BNC, RJ45, optical transceiver or other interface requirements.<\/p>\n\n\n\n<h3 id=\"wd-1803ab0b\" class=\"wp-block-wd-title title\">10. Review the Complete Link<\/h3>\n\n\n\n<p id=\"wd-d461a240\" class=\"wp-block-wd-paragraph\">Finally, verify the cable, connectors, cameras, recorders, switches and power equipment as one system.<\/p>\n\n\n\n<h2 id=\"wd-8c97813e\" class=\"wp-block-wd-title title\">Common CCTV Cabling Mistakes<\/h2>\n\n\n\n<h3 id=\"wd-f90d79cf\" class=\"wp-block-wd-title title\">Assuming Every Camera Cable Carries Power<\/h3>\n\n\n\n<p id=\"wd-eb881c4e\" class=\"wp-block-wd-paragraph\">Standalone coaxial and optical cables do not automatically power the camera.<\/p>\n\n\n\n<h3 id=\"wd-612f5d31\" class=\"wp-block-wd-title title\">Using Fixed RG59 and RG6 Distance Rules<\/h3>\n\n\n\n<p id=\"wd-f8af77f8\" class=\"wp-block-wd-paragraph\">Actual distance depends on attenuation, signal technology, connectors and equipment.<\/p>\n\n\n\n<h3 id=\"wd-3e31889d\" class=\"wp-block-wd-title title\">Running Standard Ethernet Beyond Normal Channel Limits<\/h3>\n\n\n\n<p id=\"wd-2ee0e89b\" class=\"wp-block-wd-paragraph\">Long routes can require active equipment, extenders or fiber.<\/p>\n\n\n\n<h3 id=\"wd-9cdf290f\" class=\"wp-block-wd-title title\">Choosing Cat 6 Only Because the Camera Is 4K<\/h3>\n\n\n\n<p id=\"wd-1dcc6a98\" class=\"wp-block-wd-paragraph\">Resolution alone does not determine the Ethernet category.<\/p>\n\n\n\n<h3 id=\"wd-a7aa791d\" class=\"wp-block-wd-title title\">Ignoring PoE Heating<\/h3>\n\n\n\n<p id=\"wd-f11b660c\" class=\"wp-block-wd-paragraph\">Large bundles and higher-power devices can increase conductor temperature.<\/p>\n\n\n\n<h3 id=\"wd-d49cfa3c\" class=\"wp-block-wd-title title\">Using the Wrong Coaxial Impedance<\/h3>\n\n\n\n<p id=\"wd-6e888d8c\" class=\"wp-block-wd-paragraph\">The cable impedance should match the connected video equipment.<\/p>\n\n\n\n<h3 id=\"wd-02fa850f\" class=\"wp-block-wd-title title\">Assuming Outdoor Means Direct Burial<\/h3>\n\n\n\n<p id=\"wd-175a3a5e\" class=\"wp-block-wd-paragraph\">Direct burial adds mechanical and environmental requirements beyond a simple outdoor jacket.<\/p>\n\n\n\n<h3 id=\"wd-6d9a9b8b\" class=\"wp-block-wd-title title\">Using Heavy Armour Everywhere<\/h3>\n\n\n\n<p id=\"wd-76ad0238\" class=\"wp-block-wd-paragraph\">Unnecessary armour increases cable size, weight and installation difficulty.<\/p>\n\n\n\n<h3 id=\"wd-462806aa\" class=\"wp-block-wd-title title\">Assuming Fiber Powers the Camera<\/h3>\n\n\n\n<p id=\"wd-12490fc3\" class=\"wp-block-wd-paragraph\">Standard optical fiber carries network data as light.

The exact construction depends on whether the system uses coaxial video, Ethernet or an optical backbone.<\/p>\n\n\n\n<h3 id=\"wd-e63312ad\" class=\"wp-block-wd-title title\">Which cable is best for CCTV?<\/h3>\n\n\n\n<p id=\"wd-9f36afcb\" class=\"wp-block-wd-paragraph\">There is no universal best option. Compatible 75-ohm coaxial cable can suit analogue and HD-over-coax systems. Cat 5e or Cat 6 can serve many IP cameras, while fiber works well for longer backbones.<\/p>\n\n\n\n<h3 id=\"wd-ecb21b4d\" class=\"wp-block-wd-title title\">Is RG59 used for CCTV?<\/h3>\n\n\n\n<p id=\"wd-4d59772b\" class=\"wp-block-wd-paragraph\">Yes. RG59 remains widely associated with compatible surveillance video systems.<\/p>\n\n\n\n<h3 id=\"wd-ba6a73db\" class=\"wp-block-wd-title title\">Is RG6 better than RG59?<\/h3>\n\n\n\n<p id=\"wd-1fa2799d\" class=\"wp-block-wd-paragraph\">Not automatically. The required frequency, attenuation, route length and equipment interface should determine the choice.<\/p>\n\n\n\n<h3 id=\"wd-680fd3d0\" class=\"wp-block-wd-title title\">How far can RG59 run?<\/h3>\n\n\n\n<p id=\"wd-762043c6\" class=\"wp-block-wd-paragraph\">There is no universal maximum distance. The supported route depends on cable attenuation, signal technology, connectors and the equipment specification.<\/p>\n\n\n\n<h3 id=\"wd-8bf670a1\" class=\"wp-block-wd-title title\">Can Cat 5e be used for IP cameras?<\/h3>\n\n\n\n<p id=\"wd-ae094a98\" class=\"wp-block-wd-paragraph\">Yes. Cat 5e supports Gigabit Ethernet and can serve many IP camera systems when the complete link meets the network and PoE requirements.<\/p>\n\n\n\n<h3 id=\"wd-85296f77\" class=\"wp-block-wd-title title\">Is Cat 6 better for surveillance?<\/h3>\n\n\n\n<p id=\"wd-b5bba0f7\" class=\"wp-block-wd-paragraph\">Cat 6 provides more transmission margin than Cat 5e. However, camera resolution alone does not make Cat 6 mandatory.<\/p>\n\n\n\n<h3 id=\"wd-eeae8487\" class=\"wp-block-wd-title title\">Can the same cable carry video and power?<\/h3>\n\n\n\n<p id=\"wd-c09d818c\" class=\"wp-block-wd-paragraph\">Some architectures can. PoE carries Ethernet data and compatible power on balanced copper cabling. A composite coaxial construction may also contain additional conductors, but engineers must verify their electrical suitability before using them for power.<\/p>\n\n\n\n<h3 id=\"wd-e3f83046\" class=\"wp-block-wd-title title\">What is PoE CCTV?<\/h3>\n\n\n\n<p id=\"wd-fa7a6297\" class=\"wp-block-wd-paragraph\">PoE surveillance uses Ethernet cabling to carry both network data and electrical power to a compatible IP camera.<\/p>\n\n\n\n<h3 id=\"wd-098ba217\" class=\"wp-block-wd-title title\">How far can an IP camera run on Cat 6?<\/h3>\n\n\n\n<p id=\"wd-db715ef3\" class=\"wp-block-wd-paragraph\">Conventional balanced-copper Ethernet structured cabling normally uses a maximum 100-meter channel architecture. Longer routes require another network design.<\/p>\n\n\n\n<h3 id=\"wd-a0941c20\" class=\"wp-block-wd-title title\">Can fiber optic cable be used for CCTV?<\/h3>\n\n\n\n<p id=\"wd-306e49db\" class=\"wp-block-wd-paragraph\">Yes. Fiber works particularly well for long-distance surveillance backbones, large campuses and high-EMI environments.<\/p>\n\n\n\n<h3 id=\"wd-e550964a\" class=\"wp-block-wd-title title\">Does optical fiber power the camera?<\/h3>\n\n\n\n<p id=\"wd-4c4eeb68\" class=\"wp-block-wd-paragraph\">Standard optical fiber does not carry electrical camera power. The system needs another suitable power method.<\/p>\n\n\n\n<h3 id=\"wd-34124971\" class=\"wp-block-wd-title title\">What cable should I use outdoors?<\/h3>\n\n\n\n<p id=\"wd-64cf775d\" class=\"wp-block-wd-paragraph\">Choose a construction that addresses UV, moisture, temperature and mechanical conditions. The exact solution can use coaxial, Ethernet or fiber depending on the system architecture.<\/p>\n\n\n\n<h3 id=\"wd-1f5b10a1\" class=\"wp-block-wd-title title\">Do surveillance links need shielding?<\/h3>\n\n\n\n<p id=\"wd-de705cb9\" class=\"wp-block-wd-paragraph\">Coaxial cable inherently includes a metallic screen. Ethernet shielding depends on the electromagnetic environment and complete cabling-system design.<\/p>\n\n\n\n<h3 id=\"wd-69a8e18d\" class=\"wp-block-wd-title title\">What is a composite surveillance cable?<\/h3>\n\n\n\n<p id=\"wd-dd706c6d\" class=\"wp-block-wd-paragraph\">It combines a coaxial video element with additional low-voltage conductors within one overall construction.<\/p>\n\n\n\n<h2 id=\"wd-92e04352\" class=\"wp-block-wd-title title\">Conclusion: Which CCTV Cabling Architecture Should You Choose?<\/h2>\n\n\n\n<p id=\"wd-8f06dc37\" class=\"wp-block-wd-paragraph\"><strong>What is a CCTV cable?<\/strong> In practice, it is the physical cabling that supports a surveillance-system connection. However, the correct construction depends on the camera technology and network architecture.<\/p>\n\n\n\n<p id=\"wd-d91ff39f\" class=\"wp-block-wd-paragraph\">For analogue or compatible HD-over-coax systems, begin with the required 75-ohm transmission path. Then compare RG59, RG6 or a dedicated composite product by actual attenuation and equipment requirements.<\/p>\n\n\n\n<p id=\"wd-ecaa0f96\" class=\"wp-block-wd-paragraph\">For IP cameras, use compliant Ethernet cabling. Cat 5e and Cat 6 can serve many access links, while higher-category cabling can support broader network requirements where justified.<\/p>\n\n\n\n<p id=\"wd-357e21b2\" class=\"wp-block-wd-paragraph\">If the same route needs auxiliary low-voltage conductors, evaluate a suitable composite construction. Meanwhile, large sites can use fiber to connect remote camera networks and switches over longer distances.<\/p>\n\n\n\n<p id=\"wd-57bdcd4c\" class=\"wp-block-wd-paragraph\">Finally, consider the installation environment. Outdoor exposure, EMI, PoE, mechanical risk and fire requirements can change the correct cable even when the camera technology remains the same.<\/p>\n\n\n\n<p id=\"wd-f138acb9\" class=\"wp-block-wd-paragraph\">Therefore, the best solution is not simply the thickest RG cable or the highest Ethernet category. It is the construction that matches the complete video, data, power and installation requirements of the surveillance system.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading time: <\/span> <span class=\"rt-time\"> 12<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>Cable Type Typical System Main Function RG59 coaxial Analogue \/ compatible HD-over-coax Video signal RG6 coaxial Compatible video systems Video<\/p>\n","protected":false},"author":5,"featured_media":5402,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[87],"tags":[],"class_list":["post-5404","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog-posts"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.1.1 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What Is a CCTV Cable?
