- Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors.
- It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point (P2P), point-to-multipoint (P2MP), or mesh wired or wireless links.
- Video surveillance is an important element of management and security control. New advancements in security camera and Digital Video Recording have made CCTV camera and video surveillance one of the most valuable security and loss- prevention solutions available.
- CTV security systems are reliable, efficient and simple to use. CCTV can be used to monitor virtually anything including town centres, transport system, commercial, industrial and domestic premises, visitors to buildings and access-controlled points. The CCTV images can be recorded on DVR and can be viewed locally or remotely via PC.
Infrared Technology (IR) refers to the cameras ability to capture images in total darkness. Infrared cameras are sometimes referred to as IR cameras or “Night Vision Security Cameras-. Infrared cameras have IR LEDs positioned around the outer edges of the camera lens which gives the camera its “night vision”. Infrared cameras can capture acceptable video in total darkness and even in a better quality video in low light. Even a small amount of ambient light helps the overall night vision capability of IR cameras. IR cameras are available in dome and bullet styles.
