Security camera housings are relatively simple devices but picking the wrong one can increase the cost of maintaining your security camera system. Security cameras might be placed in housings for several reasons. A camera housing gives a user the flexibility to change and replace a camera by simply opening the enclosure. This makes it easy for installers because they don’t have to dismount a camera that’s been secured to the wall. When a camera becomes defective, the housing can stay mounted while the camera is being repaired.
Even though it is not recording, a housing can be used a dummy camera until the camera is replaced. A long range lens can be added to the camera without taking the entire enclosure down. Some enclosures have added infrared light for long distance applications where IR light needs to reach objects over 100 feet. Using an enclosure with built in long range IR illuminators is useful for those who want to avoid the installation of a separate infrared illuminator. These types of enclosures can be bulky but cost effective. Some enclosures have built in heaters and blowers.
A heater will keep a camera from freezing in the harsh cold. Because cameras produce a small amount of heat from the sensor, a small amount of precipitation can start to build on the camera lens. This can create images which appear smudged. A camera heater prevents camera from accumulating precipitation and from freezing in the cold weather. An enclosure with a blower helps circulate air throughout the enclosure. This is very important for cameras installed in warm weather climates. Cameras already produce small amounts of heat from the electrical components inside of the camera body. Added heat can easily damage camera if its temperature specifications are exceeded.
