The box camera uses a separate lens that screws on to the front surface and provides flexibility for different view requirements and is sold without a lens. An auto-iris lens will have a small cable that connects to the camera for iris control in various lighting conditions.
Outdoor Dome Cameras
Outdoor Dome Cameras are typically hard shell vandal-proof casings that offer the same versatility in a variety of lens options. Day/Night outdoor dome cameras are common in applications that have entry and exit points with limited lighting during the night.
Day/Night Camera
The Day/Night camera is the best choice for low-light conditions. The cameras are standard colour during daylight conditions, the Day/Night camera switches either digitally or mechanically to a low-lux B/W mode.

Camera Enclosure
Box cameras can be mounted in a variety of enclosures. Outdoor enclosures in cold climates should include a heater/blower that keeps frost and condensation from forming on the lens and camera. Heater/Blower are commonly 24VAC and should be considered when selecting the CCTV power supply system.
Camera Location
Camera mounting location is critical to the success of the CCTV project. Cameras should be mounted as close as possible to the field of view required, and the closer the camera to the subject the better the identification of the subject will be. Proper lens selection relative to the camera location and the view required is essential to a quality picture.
