Grend 0 Posted March 9, 2004 Sorry if this topic has already been covered, I am new to this site! I have seen some small (OEM) modules for injecting DC into a coax at the receive site and another module for extracting the DC at the camera. The DC rides up the cable with the video. Can anyone advise where I can get specs for these modules and suppliers in the UK or US. Thanks G [/b] Share this post Link to post Share on other sites
