2. SURVEILLANCE CAMERA A surveillance camera is used in surveillance to monitor public or private areas that need to be monitored for security reasons.Modern security cameras use CCTVtechnolog,which employs video cameras that transmit signal to a specific limited set o monitors. Some functions of a surveillance camera are that it allows you to observe activity that is happening without you actually having to be there. There is no need to inform the people involved and you can gain access to the video via your web browser on the Internet or a local network without having to even be in the same state much less the same building. Depending on your specific needs, you can pause and still capture an image, zoom in and enlarge a part of the image, and even have the surveillance system notify you via email if there is an "occurrence" it has captured on film.

3. HOW IT WORKS? CCTV camera system includes one or more cameras which are used to send video images & audio data to a monitor. Essentially,thesecamera systems use cameras to transmit the signals to a main hub which then records that data for later viewing or live viewing if you have full time security personnel on your premises.

5. TYPES OF CCTV SYSTEM • Wired CCTV System • Wireless CCTV System

6. WIRED CCTV SYSTEM Wired CCTV systems connect the camera to the recording device & monitor with the help of standard coaxial cable or unshielded twisted pair cables or fiber optic cables. The image data is usually transmitted over a coaxial cable. The signal transmitted over these cables is then fed into a monitor or set of monitors if the image needs to be visible in different locations.

8. WIREDLESS CCTV SYSTEM Wireless CCTV systems are similar to wired CCTV systems. Radio transmitter is attached to the camera. A radio receiver then attached to the input on the monitor system or computer. Wireless systems are useful when the distance between the camera and the monitor is too far to be practical for a cable run.

The area is certainly very limited.  The wireless technology: The technology of this wireless CCTV is such that they can subject to distortion due to the other powerful devices that are installed alongside.The wired technology: The disadvantage of using a wired CCTV camera is that it cannot be ported to any other place but has to be installed in a particular part of an area and has to be left it that way for the rest of the time. Haunts the privacy at times: There are certain places where people need to have some privacy, be it the changing rooms or the toilets.
