A Guide to CCTV Cabling

Cabling is a key component of any CCTV system. Careful consideration of the cabling is required to ensure that CCTV performs effectively and reliably. What do you need to know about cabling for CCTV cameras and how can you ensure that your CCTV cabling supports reliable performance of your system?

Can I use any cable for CCTV camera?

While it might be tempting to use any available cable for cabling for CCTV cameras, it’s essential that cables specifically designed for the purpose are installed. Improper cables can result in signal loss, interference, and unreliable transmission, all of which can be problematic if you’re looking for clear, reliable footage.

The two primary types of cabling for CCTV cameras are coaxial cables and twisted pair cables.

Coaxial cables, such as RG59 or RG6, are commonly used for analogue CCTV systems. Twisted pair cables, such as Cat5e or Cat6, are typically used for IP-based CCTV systems. These cables are capable of transmitting both power and data, making them useful for modern surveillance setups.

What cables are needed for a CCTV camera?

The type of cabling for CCTV cameras will depend on the type of system and the particular requirement of the installation. Coaxial cables are typically used to transmit video signals from the cameras to the recording device or monitor on analogue systems. Twisted pair cables, often in the form of Ethernet cables, are usually used to connect the cameras to the network switch or recorder in an IP-based CCTV system. Because these cables can transmit data and power they simplify the installation process and reduce cable clutter.

Other cables may be required depending on the system being installed, such as cables for audio, Pan-Tilt-Zoom (PTZ) control, and alarm triggers.

What size cable is used for CCTV cameras?

The size of the cable used for CCTV cameras depends on various factors, including the distance between the cameras and the recording device, the power requirements of the cameras, and the type of signals being transmitted.

What is the best way to run cable for security cameras

It’s essential to ensure that cabling for CCTV cameras is routed properly to ensure efficiency and reliability. The cable route should be carefully planned before installation to minimise exposure to environmental hazards, interference, and tampering.

Sharp bends and kinks should be avoided as these can cause damage to the cables as well as cause the signal to deteriorate. Cables should be properly secured using cable clips, straps, or ties, to secure them along the route and prevent them from sagging or becoming loose over time.

Once the installation is complete, the cables should be thoroughly tested to assess connectivity and signal integrity before setup is finalised.
