gtxkid 0 Posted April 2, 2011 What is used to go 1/4 mile to a mile. They have an 18 gauge wire run that a customer has been using for that camera. They have had surge protection problem's. I think they said there Balum's are working ok. Share this post Link to post Share on other sites
Soundy 1 Posted April 2, 2011 18ga. is a bit small for a run that long, especially if they're running a 12VDC camera - I expect "surges" isn't a problem, but power dropouts. I'd suggest using AT LEAST 16ga. wire, and if it's not possible to power the cameras locally, using an adjustable power supply, measuring the voltage at the camera (WITH the camera connected and running) and dialing up the voltage at the other end until you get the appropriate 12V at the camera.

gtxkid 0 Posted April 2, 2011 I found out there is power at the camera. Share this post Link to post Share on other sites
Soundy 1 Posted April 3, 2011 Probably best to power the camera locally then (adapter near the camera). If you're using baluns, passive should be okay for 1/4 mile, but getting upwards of a mile, you may need to go active at both ends. Share this post Link to post Share on other sites
