Determining the Right Security Camera for You
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 cameras are also very durable, and can still work in extreme conditions, such as heat, cold, rain, and even high wind (some models can even withstand hurricane conditions). They make excellent outside security cameras.
Infrared technology is the basis for the second type of camera, the infrared security camera. Infrared technology, which is also found in night vision goggles, heat seeking missiles, and television remotes, measures infrared radiation (a by product of heat). It then coverts those measurements into video.
There are two drawbacks to infrared security cameras. First, because they are converting the heat signature readings into video, they can only do so in black and white. Secondly, as infrared cameras capture infrared radiation, sunlight (which also emits infrared light) can overwhelm the camera, making it worthless during the day.
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.
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 conclusion, deciding on a security camera can be challenging. It's best to use infrared security cameras when you need to see at night or in darkness. Bullet cameras make excellent outdoor cameras and are adaptable to any situation, and dome cameras make great indoor cameras.
