Welcome to The CCTV Cameras Guide
CCTV, Closed Circuit Television, is the monitoring of a specific location by the use of video cameras. This system is most often used to monitor areas that require regular surveillance such as banks, shops or areas of high security.
The camera system works by taking the signal from the video camera and sending it through to specific and limited monitors. CCTV is unlike broadcast television as it cannot be transmitted openly to the public but is a closed and private system.
CCTV is used by public services such as the police and council but can also be commissioned by private individuals to monitor their own buildings or property.
IP CCTV Cameras
The IP CCTV camera system uses the same basic technology as the standard webcam and, unlike standard Closed Circuit Television, can transmit its signal over the internet to any computer or computer based mobile device including smartphones, iPads and iPods.
The Internet Protocol used in these cameras means that they can run on a wireless system and only require power to function. These cameras are of a much higher quality than a standard surveillance system and, with the right technology attached, can even assess the activity they are monitoring and raise the alarm if unusual activity is detected.
Wireless CCTV Cameras
Wireless CCTV Cameras are based on the same principals as standard CCTV units but require no wires for transmission, only a single wire for power.
This makes wireless CCTV much cheaper and easier to install and can be more convenient in areas where a lot of wires can be inappropriate or unsightly making wireless CCTV ideal for installation in homes or small shops.
Originally based on an analogue system of transmission, most wireless CCTV is now based on a digital system which provides a much clearer and crisper picture and more definitive sound with less risk of interference.
