Baje 0 Posted January 24, 2012 Hi Everyone, I have an installation where one of the cameras is about 300ft cable distance from the DVR. I plan on running cat5 and baluns. Only problem is that i see according to a voltage drop calculater using 3 twisted pairs i still see a significant drop in the voltage. And gettin power from somewhere else along the cable run will be somewhat impossible. Will a regulated power supply solve my problem? Or do they just keep the voltage at 12vDC as opposed to cranking it up to say 13-13.5 to compensate for voltage loss? Thanks for any help Share this post Link to post Share on other sites
Soundy 1 Posted January 24, 2012 Best idea is to use a 24VAC power transformer, then add a 12VDC regulator at the camera end. If that's not possible, use an adjustable regulator (such as this: http://www.ebay.com/itm/1-5-27V-DC-Adjustable-Voltage-Regulator-Module-Board-/200615218756 - NOT AN ENDORSEMENT of this product or seller, just what came up in a google search), then measure the voltage at the camera end while you dial it up to give you 12-ish volts. The catch to this method is that IF it's an IR camera, the voltage at the camera WILL go up when the IRs turn off. Most cameras should be able to handle that, but just be aware... the preferred solution is to put the regulator close to the camera. Share this post Link to post Share on other sites
Baje 0 Posted January 24, 2012 Thanks alot. Thought of something else. Cant i just run another dedicated power cable with a higher gauge? Where im from its not easy to get ahold of these kinda things and if i can are usually fairly expensive. Think the extra power cable can work instead? Thanks for ur knowledge and help!
