Benefits of HD or 4K CCTV


Technology has improved massively over the years. First analogue CCTV, then came HD CCTV and now 4K CCTV (with 8K soon to follow). Most of us have seen examples of fuzzy images taken by analogue where you are suppose to identify the culprit. Usually, this is just a pixelated picture which is no good. HD CCTV systems make things a lot clearer. As a comparison,  a typical analogue system has a maximum of 400,000 pixels, HD over 1,000,000 (up to 4,000,000) and 4K over 8,000,000 pixels (or 8MP). By having either a HD or 4K CCTV set up, any incidents will be recorded clearly allowing you to zoom in to faces, number plates etc making convictions easier.

We can supply and install a CCTV system to meet your specifications. Call today to book a free site survey on 0800 043 3019.
