Advances in surveillance technology, coupled with cost reductions, have enabled more people to set up their own home security camera systems. The use of so-called "nanny cams" help people keep an eye on their children, examine the outside perimeter of their house from inside and monitor any workers inside the home. Cameras vary in their size and recommended usage, but the basic function remains the same. A camera needs to be hooked up to a monitor so you can see what the camera sees, and most people prefer to attach a DVR as well to record the footage.
Connect the CCTV cable to the DVR by taking the male connector of the cable and inserting it into the female "Input" jack on the DVR. If you are not using a DVR and want to connect directly to the TV without recording, plug the cable directly into the 'Input" jack on the TV, normally located in the back.
Insert the other end of the cable into the cable jack on the camera the same way you did the TV or DVR. They should twist in pretty easily. You'll want to determine the distance between the TV and the camera ahead of time to know how long your cable needs to be. If you are using a DVR, you would have the cable go from the camera to the DVR to the TV. Without the DVR, it goes from the camera to the TV directly.
Attach the power side of the cable into the power jack of the camera. It should slide in easily.
Connect the power supply plug of the camera into the other end of the CCTV cable.
Plug the power supply into a standard electrical socket.
If you want to use a DVR, connect the DVR to the TV by using RCA cables. They are colour-coded with red or white-tipped cables for audio and the yellow-tipped cable for video. The cables would run from the outputs of the DVR to the inputs on the TV, Make sure the colours match with the cable going from the yellow output of the DVR to the yellow input on the TV. You can use a coaxial cable for this instead if you need to.
