[QUOTE="Channel Hopper, post: 1110211, member: 175144"] I've been asked to change the existing RF delivery of camera images to a man cave some 170m from the front entrance since the estate where the property is based are changing the brick wall out front (it is over 80 years old and a tree root has caused a dangerous tilt) Whilst I can run a coax cable to the house from the proposed replacement wall , there is only a single coax to the cave, (plus mains) and the client is running DVB-T and S from their main dish/aerial from the roof. I am thinking of having the signals from one of those HD /IR cameras run to a cheap DVR in the cave, inserting it in the lower spectrum of the cable already providing the entertainment, though I'm not sure of the bandwidth these things take up. Splitting/dplexing the signals shouldn't be an issue if there is a margin between the lower end of the DVB stuff and the upper frequency requirement of the camera since I've got a number of adjustable Taylor boxes I can play with, client is willing to pay for the privilidge in beer tokens as well (which is nice). So, what is the needed clearance that these cameras require for moving images (whch will be colour in the daytime) , is there a ratio style graph available that determines the upper limit on the camera pixel count - 2M up to 5M ? Thanks in advance. [/QUOTE]
