CCTV Installation guidelines


Take time to plan your installation carefully as it will require longer than you think and will save you time overall. Work out the best way to run the cables back to the CCTV DVR recorder and your power source before you commence installation.

Think carefully about the sighting of your cameras and location of your recording equipment. Cameras should be out of reach and don’t under estimate the number of cameras you will require to provide proper cover. Locate your recording equipment in a secure place where it will not be found.

Ensure you have the right tools for the job: you will need a good drill, long drill bits that are capable of drilling through masonry when feeding the cables through brick work. The drill bits will also have to be wide enough to allow the ends of the cable to fit through.





DO’s & DON’Ts


tick Plan your install well and have everything ready before you start.
tick Be realistic! Don’t expect to cover a large property properly with only a few cameras, you may need more than you think.
tick Position cameras so as to capture subjects coming towards the camera rather than across the field of view.
tick Position cameras high enough to avoid vandalism.
tick Install the DVR in a secure location that will not be found by thieves.
tick Select a long range vari-focal camera if you want to cover an object or entrance that is quite far from the camera.
tick Get help from a competent person, CCTV installer or electrician if you don’t feel confident to complete the install.
cross Try to cover too much with one camera as you will lose definition.
cross Expose cable joints to the weather. You should use a junction box to protect from the elements.
cross Cut the ends of the cameras as this will void any warranty.
cross Switch on the power until you have connected and double checked everything is correct.
cross Install a DVR in a quiet area like a bedroom as they do makes some noise.
cross Expect to catch number plates unless you have positioned the camera at the correct angle and use an adjustable lens (5-50mm). At nigh you will require special ANPR cameras to capture plates when car headlights are on.
cross Cover lots of sky, it’s not important; position the camera to capture your interest.



bdot If you are using readymade BNC to BNC with power cables ensure you have them the right way around. i.e the male DC jack should be at the camera end.
bdot Use a CCTV test monitor to set up the cameras externally as its so much easier than going backwards and forwards to the monitor to check the image.
bdot Work out which way is up and down on a camera before you mount it.
bdot Use a metal coat hanger or cable rod to help get the cable through the wall. Fasten the cable with tape to the rod and push in to the hole. This will save hours of time as it prevents the cable falling down the cavity!
bdot Use junction boxes to connect the cables, use DC jacks to connect to the cameras when using RG59+2 cable.
bdot RG59 +2 cable Red = positive, black = Negative.
bdot Low Light – There is no substitute for good lighting, even IR cameras love light, the more light you have the better the image: If its dark, add a security light or a dawn till dusk light.
bdot Image quality is affected by poor weather: – rain, fog & low temperatures.
bdot Choice of Monitor – this is can have a significant effect on image quality. A traditional CRT TV screen or proper CCTV monitor will generally give the best results, especially in low light.
bdot Not enough power, ensure you don’t add too many cameras to the circuit without a good power supply. Too little amps will result in image loss especially when IRs come on in lower light.








All DVR’s are supplied network enabled and it is possible to add this functionality if you have an appropriate router and technical knowhow. This can be a complex process owing to so many factors and as such it is not possible to guide you through this process in this document.
