Hi guys,
Our local cricket club cctv system has packed in and the installer is not available to repair so we've decided to try fix it ourselves. I ordered an h view dvr box from ebay
[Edit - no links please, generic bargain bucket 16 way analogue dvr]
The new box done the trick and works with the old cameras and we now want to add a few more. The problem is they will need 100m cables from the box to the camera. They come supplied with 20m cables so I've been doing some reading and read the best option is cat5 cable with baluns. Going to give it a go but I'm just wondering is there anything I need to be aware of?
