Tips on installing CCTV to your home.
WES ELECTRICAL WESTEND GLASGOW
The prospect of drilling a hole through the outside wall of your house to run the power and video cable for a camera may seem a big job. With a little forethought it can be quite simple.
Positioning of cameras
Most people want to hide the camera as much as possible. The modern cctv camera can easily be located under or on the fascia/soffit boards where the roof meets the wall. When located here it is sheltered from wind and rain and can be shaded from most sunlight. The height of the camera gives a good area of view and minimizes the risk of vandalism.
Another advantage of this location is cabling. It is pretty easy to run the cables into the loft from this position. Many houses have a small ventilation gap between the roof tiles and the external wall, or a small hole may be drilled in the fascia board to gain access to the loft.
Cabling
It is usually quite easy to pick up mains power in the loft or, if additional cabling is required it is now internal. Wireless transmission can be used for the video signal with the receiver being placed next to the monitor or recorder (TV, VCR, PC etc.). That's it, job done.
A 'hard-wired' system is almost as easy to install. Locate the TV aerial down-lead that may be in the loft or run down the outside of the house, then run the CCTV camera video cable alongside the aerial cable, which will lead directly to the TV.
A good method of connection is an RF modulator. This changes the camera's video output to an RF output. You can pipe the CCTV images down the existing TV aerial down-lead and view on the TV/VCR as if it were another channel. If your house is fitted with a TV distribution system, this method will allow the pictures to be seen on all the TV sets.
Addition of Switchers etc.
Consider placing switchers, multiplexers or DVRs in the loft. This keeps all the cabling in the loft with just one output cable to your monitor. It also hides your recording device.
