Hi there need some help........... been asked to install a camera at a farm, the only problem i have is that the camera has to be installed down a farm track which is about 500 to 600 metres away from the house were the DVR is installed. Now what type of cable should i use and what other equipment do i need.Power has also to be run along with video as there is no power near the camera.

any help would be great thanks

you will need a big cable for power that long, but it will depend on the overall draw of the cam.

700m Yoiu 'could' use coax and amplifiers, but id go for active twisted pair, nvt etc

You could look at snt duo products, they can power two cameras (2 12v outputs, 1amp each) and allow for two cameras, all down one ct100 coax cable up to 750 meters, longer with ct125 cable.

Never tried it at that lenght, but the product works well at the short lenghts I used it for, if the specs are accurate, it may do the trick as it would give you room for a second camera also down that one cable.

Otherwise, go with baluns as suggested, and if not possible to power locally at all, then good luck on the power side..
