Closed-Circuit Television (CCTV) represents one of the most highly utilized types of security systems in operation. They rely on cameras to capture video of areas under their surveillance and possibly acts of crime. They are most appropriate for large-scale needs, such as large commercial and industrial establishments or areas, large estates, or entire communities.
Purpose of Home Security Camera Systems
CCTV may require heavy installation, so before deciding to install a CCTV system, you should identify your concerns and needs to justify the installation and expenditure. Many neighborhoods, at a communal level, use CCTV to monitor their grounds. Common needs may include reducing vandalism, reducing or supplementing the need for human guards, obtaining visual evidence of crime, and providing surveillance on a twenty-four hour basis.
For most single homeowners, CCTV may represent an overly elaborate system, notwithstanding extraordinary needs for high security. Nevertheless, you should not rely solely on CCTV for your security needs, but rather treat it as one component of an overall security system. Other components may include lighting, fencing, and motion detectors.
Design of Home Security Cameras
These systems consist of cameras which are connected by cables to a central monitoring station, equipped with monitors and possibly recording equipment, such as digital video recorders. The sophistication of the system depends largely on the quality of its cameras. Generally speaking, the more expensive cameras are more durable and reliable. However, some quality cameras are priced inexpensively, for as little as $150.
More expensive designs may include cameras hidden inside other objects such as light fixtures. More expensive cameras may also be smaller and less bulky than the more inexpensive models. As a general rule, some experts estimate that the cost of a system including monitors and cables will cost from $500 to $1,000 per camera.
Cameras vary in their abilities to point, tilt, and zoom (known commonly as PTZ), resolution, coloration, and light level. The more expensive lenses will also increase the cost of your system. You should ensure that your other system components, such as monitors and recording equipment, match the specifics of your cameras as closely as possible.
Operation of a Security Camera System
Most people program these systems to run automatically on a twenty-four hour basis. If you include human guards and monitors in your system, you may opt for real-time video. In many communities these systems are connected to local police departments.
In general, CCTV represents a popular system for home security, but is generally more suitable at the community, commercial, or industrial levels. Most homeowners do not require CCTV, especially when justifying the cost and installation.
