Closed-circuit television, or CCTV, is one of the components used in home and business security systems. CCTV cameras can help keep an eye on many different parts of a property at the same time, and they also can help keep a record of incidents. There are many options available on CCTV cameras, but an understanding of the basics of CCTV camera technology will help you to decide which camera is right for your application.
CCTV Camera Features
CCTV camera technology has come a long way in a short period of time. According to Privacyinternational.org, a CCTV camera offers a variety of remote control features that give an operator complete control. In most cases, a CCTV camera is hooked into a security system using coaxial cable, which is the same cable used to install pay television into your home. A CCTV camera can have such features as night vision and motion detection that can be set to alert the operator when anything in the camera's field of vision moves. High-end CCTV cameras can also be bulletproof. To help combat criminals that may try to deactivate a camera, a CCTV camera system can be set to record activity around a specific camera that is being attacked.
Colors With CCTV Cameras
Color CCTV camera systems cost significantly more than black and white contrast CCTV cameras, but you should look at a CCTV system based on your needs more than the color features. According to the Texas School for the Blind and Visually Impaired, a CCTV with multiple color-contrast options is ideal for viewing images, but black and white systems are preferred if you will need to read text or if you will be using a significant amount of night vision.
In some cases it may be easier to have your CCTV cameras operate wirelessly. If you are putting your camera where cabling may be difficult to install, or if you are using many cameras that are long distances from the base station, then a wireless option may be preferable. Otherwise, you may have to troubleshoot hundreds of feet of coaxial cable. You can purchase CCTV cameras that are already wireless, or you can purchase equipment to make your wired cameras run on a wireless system.
