With its growing popularity, most of the people know what a CCTV (Closed Circuit Television) system is. It comprises of a number of cameras connected to a viewing device and or a recorder. Once this system is installed, the area covered by the CCTV cameras is clearly visible on the monitor. It makes it easier to check upon the intruders and other doubtful movements. A CCTV system varies in terms of the area covered, the equipment used and the purpose of recording.
This first thing that you require to set-up a CCTV system is suitable equipment. You must have a few things clear as to what kind of recording you want and the area you would want to cover. Do you need 24hr surveillance with high definition images or something of a lighter technology will do? You would also have to choose in between black and white and color cameras; color cameras are expensive but they provide a clearer image. Then is the low light capability of the camera you are looking to install. If the area of surveillance is dark, you would need a camera of higher low light capability. You must select apt cameras as per your requirement.
The second step would be to place the cameras in a way so that they cover maximum area for surveillance. See that the display angles of the camera overlap a bit and that you avoid the blind spots while placing the cameras. Make use of a camera housing if it is exposed to elements. If you want a lesser coverage of the surveillance area, hide the cameras behind the face plates that are specially constructed for the purpose
With the help of data wiring, connect the cameras to a central monitor. The coaxial cables or the Ethernet networking cables can be used to make the connections. Arrange the wires in a way that no one is able to access them. However, if you wish to avoid the wires, you may use wireless cameras. But, similar to other wireless devices, these cameras get easily interfered by other electronic devices of the same frequency
Connect the CCTV system to a central monitor and choose your recording device. It could be a VCR or a DVR. If you are using a large number of cameras, you will require an integration unit for CCTV inputs. For viewing the recording of all the cameras at once make sure you have the required software and that your system is of the right size
The wireless cameras can be connected to the central system using a router. This can be done using the IP addresses of the cameras.
This is a basic description of a CCTV system you must know, but you would require a professional to fix it for you.
