Closed Circuit Television or CCTV as it is now more commonly known has been around since 1942 when it was first used by the Germans to watch the launch of the V2 Rocket.

CCTV cameras were usually found around the outside of commercial properties that were at high risk of burglary but nowadays are seen every day on domestic properties around the country.

Digital cameras provide a high resolution colour image during daylight and automatically switch to monochrome in low light conditions, LED’s enable continued quality images throughout the night. Cameras are terminated at a digital recorder where images are stored for later retrieval if required.

Images can be viewed remotely from the point of installation using the internet and computer, phone or tablet devices.
