Determining the Right Security Camera for You

By Chad Buie

Security Cameras are complicated, and finding the right one can be a challenge. Decision must be made about lights, security goals, lenses, and camera types. This article will cover three camera types: infrared, bullet and dome cameras.

Bullet Cameras are the most flexible cameras around. They have interchangeable lenses that can be swapped out to meet changing security needs and are lightweight, small, hearty security cameras. Some lenses are also available with infrared technology. Bullet cameras are multi-functional cameras that can be used for almost every purpose needed in a security setup.

Durable and hardy, bullet cameras are extremely effective outdoor cameras. They also have ratings that declare the temperature conditions, wind speeds, and are either water resistant or water proof.

The second type of camera is an infrared security camera. Infrared technology measures infrared radiation (which is the byproduct of heat). Infrared cameras can capture video in complete darkness, as infrared technology is most know for its use in night vision goggles.

Considering an infrared security cameras have two rather large negatives to consider before deciding whether to implement one into your security camera setup. Number one, they do not work in daylight. This is because infrared security cameras measure infrared radiation, which is a byproduct of heat and the sun. Secondly, because they capture heat, like night vision goggles, they capture in black and white rather than color video.

If you are looking for an inexpensive camera, dome security cameras are your answer. They generally mount from the ceiling and so are generally used inside. They got their name from their protective shields that encase their lenses; these domes are very difficult to tamper with and make the security camera very secure.

Dome cameras have restrictions that need to be addressed. They should not be used to capture video beyond 300 feet, as their small size and protective shield prevents them from having lenses that are capable of zooming that far. Dome cameras are used almost exclusively in hallways in hospitals, medical offices, and other offices.

In short, if you want to use a security camera outdoors it is best to use a bullet camera. If you need to see in complete darkness, the only option is to use an infrared camera or at least one with infrared technology. And lastly, a dome camera is an excellent camera to use inside, especially in hallways.
