This varies according to the number of CCTV units installed, and the type of CCTV installed.
A sequence of images is picked up on by the camera, which is transmitted as a signal that passes on to recording device and display device. The camera itself captures the video source. At the front of the camera is an opened aperture, and this is what captures the light stream through the lens. The light stream is captured by a digital chip inside the camera and turned into a sequence of images. This camera records this sequence of image and transmits either by cable or wirelessly.
Install CCTV Cameras
If you can install a camera yourself, then it’s pretty much free after you pay for the equipment.
Most cameras these days are not only easy to install on your own, but also designed to be as pain-free as possible. Some you can set on a table, mount on a wall, or attach to a magnetic surface. However, not everyone is comfortable with drilling into their walls.
There are several ways in which this can be done.
A DVR box can be connected to a TV set by a HDMI Cable, DVI Cable, component cables and s-video cable.
HDMI – Turn off TV and DVR. Connect the DMI cable to HDMI out port of the DVR Box. Turn on DVR and TV, and these will no be connected. On the TV screen you should have option to select HDMI.
DVI Cable – Turn of TV and DRVR. Plug in the DVI end of HDMI-to-DVI cable the DVI port at the side or back of your TV. Connect the audio cables to the TV and the DVR. Switch on TV and DRVR, and select “HDMI 1” as input source.
Component Cables – ensure TV and DVR are turned off. Connect the component cable’s green, blue and red connectors into the matching ports of the TV. Connect the other colour coded component cable’s connectors into the DVRs matching out ports. Next step – connect the audio cable into the TV using an audio cable. Plug the other end of the audio cable into the DVR. Switch on the TV and DVR and select HDMI 1 as an option.
S-Video Cable – turn off TV and DVR. Connect S-video cable to TV into the S-video in port, then connect the other end of cable into the S-video out port on the back of DVR. Next step – connect the audio cable to the TV and then attach the other end of audio cable into the DVR. Select HDMI 1.
, and what’s great is that they can even work without electricity. An internet connection is only required when the footage needs to be accessed remotely. Although using the internet has its benefits, it is certainly not a necessity.
