purvissp 0 Posted February 8, 2014 Hello, new to the forum and need some help. I just purchased a Uniden UDR444 Guardian 4.3-Inch Video Surveillance System with 2 Cameras (UDR444) and I need to know a couple of things. The 9v camera cords are very short, is it safe to use cable extenders for the power supply cord (Uniden was not sure). Also are the plugs, male, 2.1mm or 2.5mm? Thank you for your advice.

purvissp 0 Posted February 9, 2014 Thank you, that's a great idea. I'll take the charger and cord over to RS as soon as it arrives. Share this post Link to post Share on other sites
