Security

The most obvious use of CCTV on a farm is to provide security. Farms usually cover a large area, for CCTV to be effective it needs to capture detail and this means zooming in on smaller areas. A camera with a wide angle lens will capture the whole of a yard area or large shed enabling you to see general movement but it won't allow details to be recovered from the footage. Incidentally on this point if you've seen films where they zoom in on an image and miraculously detail appears from nowhere we've got some bad news for you. In real life that doesn't happen, in the real world your image just gets more and more unreadable.



CCTV cameras for farms

The distances involved on a farm tend to be quite large so for this reason you need to be looking at more telephoto lenses. The 2.8-11mm lens is a good all round lens for closer work, general overviews or fitting inside storage sheds. Our 9-22mm lens can capture detail at further distance, up to 15-20 metres. This could also be fitted inside a larger storage shed. Finally our B8 series 6-60mm long range cctv camera is fantastic at capturing high levels of detail at distances of up to 50-60 metres



Typical CCTV equipment for farms

CCTV cables for farms

We have already mentioned using Cat5 cable and video baluns for wiring. Often distances from cameras to the DVR recorder can be quite long. Our standard video baluns will transmit a signal up to 300 metres along a length of Cat5 cable. It is essential to use pure copper Cat5 cable and not CCA (copper coated aluminium) as this does not work well with video baluns. Quite a lot of CCA Cat5 is marketed and sold as pure copper when it isn't so it's essential to find a good source. We supply external grade pure copper Cat5 which is well suited to farms.
