The camera should have Infrared (IR) capabilities to best meet the requirement of identifying individuals under various lighting conditions. Infrared allows cameras to capture clear images in low or no light, making it possible to identify individuals regardless of the lighting conditions. Motion-activated features do not guarantee image clarity in different lighting, and a zoom function could compromise the ability to automatically capture all individuals passing by the camera if not set up properly. High resolution is beneficial, but without infrared, poor lighting conditions can still render images unusable for identification.
