Like most systems a poor input yields a poor output. CCTV cameras should be matched to their applications. If you want to record faces then a low resolution camera will not work. Want to recognise faces at night then additional technologies are required. A good camera will allow for facial recognition, numberplate recognition, motion detection, smoke detection and other analysis systems to be accurate. Having historical recorded video as evidence enables all interested parties to see what happened as well as potentially influencing it happening in the first place.
CCTV systems are often integrated with both access control systems and intruder detection systems to create a holistic layered security solution to protect a businesses assets, employees, visitors and customers.
