Choosing a security camera can be difficult, as there are many options. Before deciding on a specific model, general questions must be answered: will the camera be inside or outside? in good lighting conditions or in darkness? How far away does the camera need to capture. This guide covers three 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.

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.

Infrared security cameras, however, have two drawbacks. One, they are only able to capture black and white video, and two, they cannot be used during the day, as sunlight will wash out the sensor’s ability to capture heat. Infrared technology should also not be used near reflective surfaces.

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.
