Determining the Right Security Camera for You

By Chad Buie

Deciding upon a security camera can be complicated, with decisions that must be made about lenses, lighting, and camera type. This guide will cover the first three different camera types: bullet, infrared, and dome cameras.

Things change, but when they do so can a bullet security camera. A bullet camera's interchangeable lenses allow it to adapt to changing security needs, which often makes it less expensive than other cameras. Also many bullet cameras lenses have infrared technology that automatically detects when there is not enough light to capture color video.

Bullet security cameras make excellent outdoor cameras, as they are able to be used in hot, cold, rain, and even hurricane winds. They are extremely hardy cameras.

Infrared security cameras are the second type of camera, which only capture in black and white. This is caused because, infrared cameras work by measuring infrared radiation (IR). Infrared technology converts IR, which is a byproduct of heat, readings into video.

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.

Dome Cameras are the last type of camera discussed in this guide. Dome cameras are known for the tamper proof dome that encases their lens. Dome cameras are also the cheapest cameras around. They mount from the the top, and thus are used almost exclusively inside.

The dome on a dome security camera does have two drawbacks. First, it prevents most dome cameras from being used outside as most dome cameras must be hung from the ceiling. Secondly, dome camera's domes prevent these cameras from installing long distance lenses, so you will not be able to capture video beyond 300 feet.

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.
