Finding the Right Security Camera
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.
Bullet Cameras are the most flexible cameras around. They have interchangeable lenses that can be swapped out to meet changing security needs and are lightweight, small, hearty security cameras. Some lenses are also available with infrared technology. Bullet cameras are multi-functional cameras that can be used for almost every purpose needed in a security setup.
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.
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.
A dome camera is not a good fit for security needs that require the user to capture video beyond 300 feet. The small size of dome security cameras restricts their zooming capabilities. Dome cameras are the preferred cameras for hallways, and are mostly used in medical offices, hospitals, fast food chains, and small 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.
