Surveillance cameras come in many forms and sizes, are wired or wireless, and some even have features such as motion detectors. They can be set up in public places or in the privacy of a home.
Traffic Safety Surveillance Cameras
Next time you drive through an intersection, look up to see whether a camera is mounted on the traffic light pole. These traffic safety surveillance cameras are there to give operators and emergency units a visual of traffic congestion and vehicle accidents. Some are even mounted to take a picture of a car's license plate if they run a red light.
Home Surveillance Cameras
People use home surveillance cameras to not only protect themselves from intruders, but also to monitor what is going on inside the house. Outside cameras sometimes have night vision and are known as motion sensor cameras, which use infrared energy. The camera will use the difference in a infrared light pattern to trigger an alarm or a floodlight. Infrared energy will detect any movement within its view and activate. Night vision cameras use the same monitors that motion sensor cameras use, except it uses infrared emissions, which puts together a high resolution image. Even if it is in pitch dark, the image will be revealed. Cameras on the inside of the house can be made so small that they can stick on the side of stuffed animal toys or be placed on shelves between objects. These are sometimes used to monitor a nanny or babysitter.
Other Features of Home Surveillance Cameras
All home surveillance camera systems come with numerous cameras, usually somewhere between eight and 32. They will additionally come with a DVR recording unit that allows each camera angle to be recorded on a hard disk. This allows the owner to have a long recording time and the ability to look at previously recorded images.
Fake Cameras
The most inexpensive way to put up a surveillance system on your property or business is by installing fake video surveillance cameras. They are designed to trick people into thinking they are being recorded.
Wireless Video Cameras
Wireless video surveillance cameras have become one of the most common forms of cameras because they are convenient to use in your home or office. Cameras can be positioned easily. They are powered by batteries and then inserted with a video receiver that will send a live feed back to your television, VCR or computer.
