CCTV Camera

It is almost impossible to move around town these days without being spotted by at least one CCTV camera. Most people will encounter several cameras in the course of their normal day. Cameras are used primarily for security but also for many other roles. The types available range from tiny pinhole cameras to large cameras that can be remotely pointed in any direction. Before installing a CCTV camera system, consumers need to be aware of the laws regulating their use. There are severe penalties in most countries for the illegal use of surveillance cameras.

A CCTV camera is one that is used to send a closed-circuit television (CCTV) signal. It is not broadcast like a television signal and can only be viewed by those who have access to the system. Technically, a CCTV camera is just like any other camera. The signal is usually sent over a cable but may also be sent through a secure wireless connection. The camera will usually have a few modifications that allow it to operate in harsh environments, but these changes are usually limited to the housing and support structure.

The number of roles that a CCTV camera can be used for has grown steadily since they were first introduced. Initially, they were used by governments for security, surveillance, and traffic monitoring. The widespread use of cameras has allowed police to quickly solve many crimes that would otherwise have taken much longer to solve, and some crimes would never have been solved without them. They were also adopted by businesses for theft prevention and facilities management. Around the home, cameras are used in video intercoms and some alarm systems.

When choosing a CCTV camera, it is important to consider where it will be installed. A waterproof housing is essential for outdoor use, along with a shroud to prevent water and dirt from getting on the lens. Locations with poor visibility or no lighting may require extra lights installed, or the use of an infrared camera that can see in the dark. Battery-operated wireless cameras are ideal for locations where installing cables would be costly and unsightly. A camera with a high resolution is important for identifying small details, like number plates. Also, a color camera is generally better for identifying people that a black and white camera.

A CCTV camera is only one part of an effective monitoring system. The other parts include monitors, recorders, multiplexers, and the cabling that connects them all together. Older systems that use VHS tape recorders are setup to record in time-lapse mode, taking one frame of video every few seconds to make the tape last longer. Newer digital systems work like a computer and use hard drives instead of tapes, avoiding the need for time-lapse. Digital cameras can also stream their video across an existing computer network, substantially reducing their installation cost.

Despite the drop in price of the average CCTV camera system over the past few years, it is still an expensive option for many small businesses. Fake cameras are a cheaper option that can be used in some roles, such as theft prevention. Some stores use fake cameras and empty domes to give customers the impression that they are being constantly watched. The low cost of these devices allows more of them to be installed around the store, but installing too many can be a giveaway that they are fake.

The huge growth in CCTV camera numbers over the last few years has given rise to concerns about privacy. There has been a great deal of legislation passed that regulates their use, particularly in the workplace. These laws vary widely between countries so it is important not to assume that they are the same everywhere. Companies that illegally use cameras in the workplace also risk being sued by their employees, and using them around the home can cause trust issues within the family.
