What CCTV camera resolution do I need ?

The camera resolution required will depend on whether you want to detect, observe, recognize or identify. We typically use HD CCTV cameras with between 3 and 8-megapixel resolution (8MP CCTV cameras are termed 4K CCTV cameras). You will require 40 pixels per face or 5 pixels/cm for identification. Our designers will ensure that suitable CCTV cameras are selected for your system. Below we show you the difference between common camera resolutions.
