CCTV Cable for Video Surveillance and Security Systems

CCTV Cable provides signal connectivity for closed-circuit television, surveillance and building-security systems. ETK Kablo manufactures a composite CCTV cable with one 75-ohm coaxial video element and additional signal conductors, together with a dedicated multi-core intercom cable for doorphone and communication systems.

The ETK Kablo CCTV range includes the CCTV (1 Coax) construction and Intercom Cable (DT). The CCTV cable combines coaxial video transmission with additional low-voltage signal conductors inside one overall cable, while the intercom product provides multi-core copper connectivity for door-entry, audio and communication circuits.

Selecting the correct surveillance cable depends on the camera technology and system architecture. Traditional analogue and compatible HD-over-coax systems can use 75-ohm coaxial transmission, while IP cameras normally use Category-rated Ethernet cable such as Cat 5e or Cat 6. Power, control and communication requirements should therefore be specified separately rather than treating every security-camera system as electrically identical.

What Is a CCTV Cable?

A CCTV cable connects surveillance equipment within a closed-circuit television system.

Depending on the system architecture, the cable can carry:

• Analogue video signals
• Compatible HD-over-coax video signals
• Low-voltage auxiliary signals
• Control or communication circuits where the cable construction provides them

The exact conductor and screen architecture should match the camera, recorder, control equipment and installation environment.

ETK Kablo CCTV Cable Range

Product	Main Construction	Primary Application Direction
CCTV (1 Coax)	One 75-ohm coaxial element plus additional signal conductors	Video-surveillance installations requiring coaxial video and auxiliary signal conductors
Intercom Cable (DT)	Multi-core flexible copper cable	Intercom, doorphone and building communication systems

The product range focuses on practical surveillance and building-communication connectivity.

CCTV (1 Coax) Composite Cable

CCTV (1 Coax) combines one coaxial video-transmission element with additional low-voltage signal conductors within the same overall cable construction.

The ETK Kablo coaxial element uses:

• 7 x 0.20 mm stranded copper center conductor
• Solid polyethylene dielectric
• Electrolytic copper braid

The coaxial electrical data includes a characteristic impedance of 75 ± 3 ohms, mutual capacitance of 54 ± 2 pF/m and propagation velocity of approximately 0.82.

The additional signal conductors use 0.22 mm² stranded copper in the available configurations.

Why 75 Ohm Coaxial Cable Is Used for CCTV

Many analogue and compatible video-surveillance systems use a nominal 75-ohm transmission path.

Matching the characteristic impedance of the cable and connected equipment helps control signal reflections and maintain video quality.

The ETK Kablo CCTV (1 Coax) product has a characteristic impedance of 75 ± 3 ohms for its coaxial element.

A 50-ohm RF cable should not automatically replace a specified 75-ohm CCTV cable simply because both products use coaxial construction.

Composite CCTV Cable

A composite CCTV cable places more than one circuit type inside one overall cable.

In ETK Kablo's CCTV (1 Coax) construction, the coaxial element carries the video signal while additional copper conductors provide separate low-voltage signal paths.

This architecture can reduce the number of individual cables required along a surveillance route and simplify installation where the connected equipment requires both video and auxiliary conductors.

The additional conductors should not automatically be treated as camera-power conductors without checking their cross-section and the electrical requirements of the camera system.

CCTV Coaxial Cable Construction

Component	ETK CCTV (1 Coax) Construction
Center Conductor	7 x 0.20 mm stranded copper
Coaxial Dielectric	Solid polyethylene
Coaxial Screen	Electrolytic copper braid
Characteristic Impedance	75 ± 3 Ω
Additional Signal Conductors	0.22 mm² stranded copper
Additional Signal Screen	Al/PET tape in applicable construction
Outer Jacket	PVC, halogen-free or polyethylene options according to construction

Screening in CCTV Cable

Video-surveillance cables can operate near power circuits, lighting equipment, motors and other sources of electromagnetic interference.

The coaxial structure itself provides a concentric screened transmission path. ETK Kablo's CCTV (1 Coax) product uses an electrolytic copper braid around its coaxial element.

The additional signal section can also use an Al/PET screen in applicable variants.

Correct termination remains important. The performance of a screened cable depends on connectors, continuity of the screen and the complete installation design.

Copper Conductor CCTV Cable

ETK Kablo's CCTV (1 Coax) product uses copper conductors for both the coaxial and additional signal elements.

The coaxial center conductor uses a 7 x 0.20 mm stranded copper construction, while the auxiliary signal conductors use 0.22 mm² stranded copper.

Conductor construction affects resistance, flexibility and signal performance. Buyers should therefore compare exact conductor material and dimensions when evaluating CCTV cable quotations.

CCTV Cable with PVC, LSZH and PE Options

ETK Kablo CCTV (1 Coax) constructions include multiple material options according to the applicable variant.

Outer-jacket options include:

• UV-resistant PVC
• UV-resistant halogen-free material
• UV-resistant polyethylene

The additional signal conductors can also use different insulation material systems according to the exact construction.

Material selection should follow the installation environment and project fire requirements rather than assuming that one jacket type suits every CCTV project.

PVC CCTV Cable

PVC CCTV Cable can provide a practical construction for suitable indoor and protected installations where the project permits PVC materials.

PVC should not automatically be associated with one universal fire classification or environmental resistance level. The exact cable construction and project documentation should determine compliance.

LSZH CCTV Cable

LSZH CCTV Cable uses halogen-free materials where the project requires specific smoke and halogen characteristics.

Applicable ETK Kablo CCTV constructions include smoke-density, halogen-content, corrosive-gas and flame-retardancy test requirements.

LSZH does not mean fire resistant. A low-smoke halogen-free surveillance cable does not automatically maintain electrical continuity during prolonged fire exposure.

PE CCTV Cable for Outdoor Installations

Selected ETK Kablo CCTV constructions use a UV-resistant polyethylene outer jacket.

PE can provide an appropriate material direction for external surveillance routes where environmental exposure forms part of the cable specification.

However, outdoor suitability should always be confirmed from the exact product construction, route and installation method.

A PE jacket should also not be confused with mechanical armor.

Analogue CCTV Cable

Traditional analogue CCTV systems transmit video over a dedicated coaxial path between the camera and recording equipment.

A 75-ohm coaxial architecture remains relevant to these installations and to compatible surveillance technologies that continue to use coaxial video transmission.

System designers should verify camera technology, transmission format and maximum route length before selecting the cable.

HD-over-Coax CCTV Systems

Several modern surveillance technologies can transmit higher-resolution video while retaining a coaxial cabling architecture.

Where the equipment manufacturer specifies a compatible 75-ohm coaxial transmission path, cable attenuation and route length become important design parameters.

The exact camera and recorder specification should determine whether a particular CCTV cable is suitable for the required resolution and distance.

CCTV Cable vs RG Coaxial Cable

CCTV cable and general RG coaxial cable can overlap in video applications, but the product categories serve different procurement requirements.

Characteristic	ETK CCTV Cable	ETK RG Coaxial Cable
Main Product Concept	Surveillance-specific composite construction	Standalone coaxial transmission cable
Video Element	One 75-ohm coaxial element	Depends on exact RG type
Additional Signal Conductors	Available in CCTV (1 Coax)	Not part of a standard standalone RG cable
Typical Procurement Logic	Camera / surveillance system requirements	RG designation, impedance and RF/video performance

Where a project requires only a standalone coaxial video cable, ETK Kablo's Coaxial Cable portfolio provides multiple RG constructions. Where the route also requires additional signal conductors, the composite CCTV construction can provide a more integrated solution.

CCTV Cable vs Ethernet Cable for IP Cameras

Analogue CCTV and IP CCTV use different transmission architectures.

System Type	Typical Cable Direction
Analogue / compatible coaxial CCTV	75-ohm coaxial or composite CCTV cable
IP Camera Network	Cat 5e, Cat 6 or another suitable Ethernet category
Long-Distance IP Network	Ethernet infrastructure or fiber optic network according to design

IP cameras should therefore not be connected with a conventional coaxial CCTV cable unless the system includes equipment specifically designed to convert between the technologies.

CCTV Cable vs Cat 6 Cable

Cat 6 cable is a four-pair balanced Ethernet cable designed for data networking, while a CCTV coaxial cable uses an unbalanced 75-ohm coaxial transmission path.

Cat 6 is relevant to IP surveillance networks, especially where cameras communicate through Ethernet switches and network video recorders.

Composite CCTV cable remains relevant where the surveillance equipment uses coaxial video and separate auxiliary circuits.

CCTV Cable and Power over Ethernet

Power over Ethernet belongs to IP-based surveillance networks rather than conventional coaxial CCTV architecture.

PoE allows compatible Ethernet cabling to carry both network data and electrical power to an IP camera.

A CCTV composite cable should not be treated as a PoE cable simply because it contains several copper conductors.

For PoE camera networks, ETK Kablo's Cat 5e, Cat 6 or higher-category Data/LAN cables should be evaluated according to the required Ethernet and PoE performance.

CCTV Cable for Commercial Buildings

Commercial properties can use surveillance systems throughout entrances, corridors, parking areas, technical rooms and external perimeters.

The correct cable depends on whether the project uses analogue cameras, HD-over-coax equipment or IP surveillance.

Indoor and outdoor sections can also require different jacket materials and installation methods.

CCTV Cable for Industrial Facilities

Factories and industrial sites can create challenging electromagnetic and mechanical environments for surveillance networks.

Camera routes can pass near motors, power cables, drives and other electrical equipment. Screen construction and cable routing therefore deserve particular attention.

Where the surveillance system uses Ethernet cameras, a suitable screened or industrial Data/LAN cable may be more appropriate than coaxial CCTV cable.

CCTV Cable for Transportation Infrastructure

Airports, railway stations, metro facilities and other transport environments often use extensive surveillance infrastructure.

The project can require different cable characteristics according to indoor or outdoor routes, smoke and halogen requirements and the selected camera technology.

LSZH material requirements should be evaluated separately from video-transmission technology and circuit-integrity requirements.

CCTV Cable for Outdoor Security Cameras

Outdoor surveillance routes expose cable to sunlight, temperature changes and environmental conditions that differ from indoor installation.

ETK Kablo offers UV-resistant PE, PVC and halogen-free jacket options within the CCTV (1 Coax) product family.

The exact cable should be selected according to the actual outdoor route rather than assuming that every CCTV cable is weather resistant.

CCTV Cable Electrical Characteristics

The ETK Kablo CCTV (1 Coax) product has the following key electrical data for its coaxial element:

Parameter	Value
Characteristic Impedance	75 ± 3 Ω
Mutual Capacitance	54 ± 2 pF/m
Propagation Velocity	Approximately 0.82
Operating Voltage	300/500 V
Test Voltage	1200 V

Electrical requirements should still be verified against the exact product configuration and surveillance equipment.

CCTV Cable Temperature and Bending Radius

The ETK Kablo CCTV (1 Coax) product has an operating-temperature range of -30°C to +70°C.

The minimum bending radius is 15xD, where D represents the overall cable diameter.

Respecting the bending radius helps prevent excessive mechanical deformation of the coaxial geometry during installation.

Intercom Cable (DT)

Intercom Cable (DT) provides multi-core copper connectivity for intercom, doorphone and building communication applications.

The cable uses stranded copper conductors, polyester wrapping and PVC or halogen-free material options for building communication applications.

Available configurations include 4, 6, 8, 12, 16 and 20 conductors.

Conductor cross-sections include 0.14 mm² and 0.22 mm² options.

Intercom and Doorphone Cable

Intercom systems connect entrance panels, handsets, indoor stations and related building-communication equipment.

The exact number of conductors depends on the communication system and equipment architecture.

ETK Kablo's Intercom Cable range provides multi-core configurations up to 20 conductors.

System installers should determine conductor count and cross-section from the doorphone or intercom equipment specification.

PVC vs LSZH Intercom Cable

The ETK Kablo Intercom Cable is available with PVC and halogen-free insulation and outer-jacket options.

PVC can provide a conventional material solution where permitted by the project.

Halogen-free variants can suit buildings where low-smoke and halogen-related requirements form part of the specification.

The material system should not be confused with communication protocol or conductor count.

Intercom Cable Electrical Data

The Intercom Cable has a 300/500 V operating-voltage rating and a 1200 V test voltage.

The operating-temperature range is -30°C to +70°C, with a minimum bending radius of 10xD.

The exact conductor count, cross-section and material configuration should be specified during procurement.

CCTV Cable Fire and Smoke Requirements

Fire-related requirements belong to the exact cable construction rather than the generic term CCTV cable.

Applicable ETK Kablo CCTV and Intercom variants include test families such as:

• IEC 61034-2 for smoke density
• IEC 60754-1 for halogen content
• IEC 60754-2 for corrosive-gas characteristics
• IEC 60332-1-2 for flame retardancy

These tests should be applied according to the exact material variant and technical documentation.

LSZH CCTV Cable Is Not Fire Resistant Cable

Low-smoke halogen-free construction addresses smoke and halogen characteristics during combustion.

It does not automatically mean that video, control or communication circuits remain operational during a fire.

Where the project requires defined fire-resistant circuit integrity, a separately tested fire-resistant cable construction should be specified.

How to Specify a CCTV Cable

A complete CCTV cable RFQ should identify the surveillance technology and cable requirements clearly.
