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.
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.
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.
The third type of security camera is a dome security camera. Dome cameras are the least expensive cameras around, but are generally only used inside, as they generally mount from above. Dome cameras also have protective shields which make tampering with them very difficult.
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.
