What is CCTV?

By Jonathan Ratcliffe

Closed-circuit television (usually shortened to CCTV) is effectively a network of cameras that films the area around them. The system broadcasts the footage to a specific system – allowing you to monitor what is going on. This means that the most common application of CCTV is for security cameras – for example in public areas, in the home, or on business premises.

The cameras can all be linked together and monitored in one place. There are a variety of ways that these systems can be configured, a traditional set up normally means that cameras are fed into a monitor which can then be monitored live or viewed retrospectively. The most up to date systems are also compatible with a variety of mobile phones or tablets, meaning that you can link up with your system, and view CCTV cameras wherever you are, providing a reassuring security option for your home or business.

CCTV systems can be set up with a number of different types of camera.

Analogue cameras are the most common type used.

Wired cameras are suitable for use in video surveillance for security purposes, although the signal can weaken over distance. Luckily there is a range of signal boosters that can be incorporated into the CCTV system to help create an interconnected network around a large site.

Wireless cameras can also be used – a network doesn’t have to be connected by wires in order for it to be ‘closed circuit’.

IP (internet protocol) cameras are an increasingly popular choice for CCTV systems, and are generally considered to offer the best quality images, with a range of remote control options such as zoom and repositioning.
