I'm pricing an install where I need to future proof for expansion. Currently 16 cams on site, I'll be adding another 8 but with potential for 8 more after that (I'm swapping out existing DVR & installing 2 x 16 ways). I need to allow for some redundancy in case of cable breakdown & the additional possibility of maybe 1 or 2 more cameras. Power will be available at the camera split location where the duct comes out the ground. then run up a pole where cables will be aerial with catenary wire. This will prevent voltage drop.
All cams will be HD-TVI 1080p 2mp 2.8mm - 12mm varifocal domes/bullets depending on location.
I have to install cams approx 100 or so metres away from DVR. I came across a US manufacturer who makes 4 or even 8 CAT cables in one outer sheathing. This would need to be duct grade preferably gel filled. Obviously I can pull 4 in, but if there is a supplier in the UK that does this I would like a price. I have trade accounts with Luxrite, System Q, CEF, Kew, HBL, Norbain, Techvision, SAS but none of them do this.
I have contemplating putting a cab in to the expansion area and multiplexing the signals back to the DVR then separating them maybe using fiber, but I think the cost will be prohibitive.
Any suggestions?
