The average CCTV product guide is so highly charged with specs and numbers that it’s enough to put many completely off the idea of getting a camera installed at the gate. The good news is that it need not be complicated at all; you’ll see that after working through this web page.
CCTV is by no means only within reach of the wealthy. You can set the ball rolling by starting off with a single camera, a power supply and some cable. This need not cost you an arm and leg. It’s only when you’ll want to add more cameras that you’ll have to start investing in either a Video Splitter or a Digital Video Recorder (DVR).
Standard off-the-shelf cameras come with fixed lenses giving you about a 60 to 70 degree view. These cameras need decent light at night to be effective. Choose a camera with built-in infra-red led’s that will allow you to see between 15 and 30 meter away in the dark. (Longer distances will obviously cost more). Alternatively mount it next to a strong low consumption led spotlight. This may be even more effective.
Cameras can (but don’t have to) be hooked up to a recording device. There is no evidence that this will act as a deterrent. Also keep in mind that the use of any recordings in a court of law is not always admissible. It will probably only be useful if you want to use these recordings for your own peace of mind.

How Will I View My Surveillance Camera?
A dedicated small 12 volt monitor. Models offering around 5 to 7 inch screens are available.
A Flat Screen Computer PC monitor. You’ll need to hook it up to a VGA Converter to be able to view the picture.
Any stand alone TV with AV input. The camera is connected to the AV input. Switch between normal TV and your surveillance camera with the TV/AV button on your remote.
Your cameras can also be connected to a network of TV’s in your house if they are connected to a central decoder. You’ll need to acquire a Video Modulator and incorporate it at the decoder to achieve this. Your cameras now become viewable as t TV channel on your remote control.
Traditionally C-Axial cable (RG-59) has been used. Picture quality drops off when the cable length exceed about 130 meter.
PC network cable (CAT5) is an excellent cable to use. This cable consists of 4 pairs of twisted cable; which means that you can theoretically get the images of four cameras on each cable. (That is if you don’t use any of them foe powering up the cameras). You’ll need two Baluns for each camera if you want to use this type of cable.
It is advisable to use lightning protection on these cables; especially if your cameras are hooked up to expensive TV’s and a DVR. We are always available to assist you with your CCTV system design.
