Closed-Circuit Television, CCTV is a reliable means of security. It monitors a premise continuously and records all the activities going on in that particular premise in a Digital Video Recorder (DVR). It serves as a deterrent to crime as people refrain from any misdeeds in the presence of this device. Even if any crime is committed in the premise, the wrong doer can be easily caught with the help of this application. It will record all the incidents going on in the range specified by this system. The events can also be viewed live for immediate actions in case of any suspicious activity.

However, there is one small problem with any CCTV camera in India. You do not get more than what you see! For example, suppose you install an application in a closed room at one corner. It will have a predetermined focal length. The lens that majority of them use are fixed lenses. The angle of the shot cannot be adjusted. The shot cannot be narrowed or widened. The area that is seen in the recording cannot be even slightly changed to get a better shot from a different angle or focus on a certain corner.

This limitation ...
... may cause problems when it comes to CCTV cameras in India. A common problem with any normal application is that it requires the intruder to stand very close to the application in order to be identified. In any case, the system is installed at a height to protect it from deliberate damage. There are very little chances of getting a recognizable image of the intruder in the recording if the distance between the intruder and the camera is more. A fixed focal length makes it impossible to identify the face of the trespasser. A varifocal security camera in India may overcome this limitation.

Varifocal dome cameras in India come as a relief in such a situation. These applications have a special kind of lens known as the varifocal lens. These lenses can change their focal length at any point of time. You can refocus your shot after adjusting the focal length to get a tighter shot.

Varifocal dome cameras in India usually have a joystick for operation. The application can be installed at any location in a premise. The incidents going on in the premise can be viewed from a distance with the help of a DVR.

A varifocal security camera in India, thus, gives him a better shot of that particular area on which he is focusing.
