We not talking about fish here. The DORI standard was developed by the British Security Industry Association, BSIA. DORI stands for Detect, Observe, Recognise, Identify. The DORI distance is a “general proximity” of distance which makes it easy to pinpoint the right camera for your needs.
The BSI document titled “planning, design, installation and operation of CCTV surveillance systems code of practice and associated guidance” covers many aspects of surveillance systems.
