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.
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.
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. Second, 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 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.
