High Contrast Lighting Cameras
Widely differentiating light conditions are usually refrained from in professional photography. Over- or underexposure are the usual outcome as either too much or not enough light makes it's way to the camera's sensor.
For security cameras we do not have this luxury as neither the place nor the time will be chosen for the scene. Furthermore, security cameras are supposed to survey independently and thus would need to react on changing conditions.
The newest technology regarding Wide Dynamic Range features will deliver sharp contrasted images in less then ideal conditions. Scenes with partial in and outdoor areas, dark shadows and daylight, will produce clear and analysable images.
Super low lux recordings are another point of quality criteria for a security camera. If the camera fails to produce a clear nightvision image the investment was wasted.
The priority for the current standard of security cameras is the recognition of faces (i.e. humans) and number plates. To allow a comprehensive recollection of recorded events. The video may even be cross-referenced to other simultaneous occuring data such as POS transactions or parking enforcement information.
