CCTV is the use of video cameras to send out a signal to a specific, small set of monitors. Many stores use cctv as a theft prevention deterrent. Cctv is used in a wide range of areas where large amounts of people gather. Cctv is also used in areas where security is very important. Many factories use cctv to keep track of entrances and exits.
Cctv is different from broadcast television due to the fact that the signal is not openly transmitted. Cctv is widely used for surveillance. Cctv is generally used in areas that need heightened security. Banks, casinos, and airports and military installations often use cctv in addition to security patrols. Cctv allows these areas to employ less security officers and still have a high security level. Many, if not all, cctv systems allow images to be recorded. These recordings can be used in case of any theft, security breaches or other incident.
IR cameras combine a black and white camera with infrared illuminators for night time surveillance. Even if you use color night vision cameras, they will switch to black and white when used with the IR LED’s at night. This is because black and white cameras produce a better image that color cameras in low light levels. Cameras that are able to switch modes are also called day/night cameras. A built-in light sensor determines when light has changed enough for the camera to operate in night mode and prevents the switching of modes due to a cloud or another temporary object.
To view or record clearly in the minimum light we are recommending this cameras for scattered light places like factories. The camera comes with minimum of 10mtr IR to maximum of 100mtr IR Distance. The Distance mentioned in the product is to capture the image in the night time upto the specific distance but the picture clarity will be depends upon the TV Lines of the cameras.

DVR is an integrated system which accommodates different combination of multiplexers, quads, video recorders and alarm controllers. This system represents a great step forwards beyond any of conventional analogue surveillance systems. The system not only performs monitoring, motion detection, alarm control and different electric/electronic devices control at the same time, but also stores images from camera into hard disk for playback later.
Through networking it can be easily accessible from anywhere and at any time. Further, the system employs an easy-to-use interface which maximizes the efficiency of the surveillance.
We are proud in introduction of these user-friendly systems to you. The system is best equipped with advanced technologies.
