street cameras

[c2lkis 0]

Hi there... I've been installing cameras for over 2 years now but i havent tried installing long cable runs with coax and utp cables. Currently the longest coax cable run that i made was a 200m RG59-U (with power) and using a 18CH 20A Centralized PSU. Same with 4wire-UTP with power cable, using Passive Video Baluns, 150-200m cable runs.

 

Problem that I encountered frequently is voltage drop, especially when all cameras are long cable runs and using varifocal cameras or cameras high beam IRs that usually need more wattage. I was forced to install power adapters(12V 1A) for each cameras.

 

What system should I use especially long cable runs? Should I use long rang IP cameras but I haven't tried it since I think it needs to be in light of sight (the receiver and transmitter antennas)?

As distances are typically quite large for street camera projects, work on the basis that you need to provide main power in each pole and for transmission only consider fibre optic cable or wireless (E Band has the best reliability in most locations that have line-of-sight).

We always use fiber optical. If the distance is too far like 3-5km, we use wireless transmission system.
