  1. Please forgive my layman's questions. I need to purchase a 12v power distribution 18Ch box for my 16 hard wired cameras (large house...large gardens, some self build plots we are developing) Most boxes on Amazon/Ebay offer either 10a or 20a or 30a with subsequent price increases 1. what is the recommended amperage 10/20/30a and why...I wish to keep the purchase price as low as possible 2. are the distribution boxes designed so that each channel supplies 12v to each camera; obviously with a smallish reduction due to cable length/efficiency
  2. I have seen this weird lines showing up randomly during different nights. What is the issue here? I have checked the voltages, wires, everything is fine. My system is made of 1 Hikvision DVR, 2 power supplies 12V 5A, 4 Hikvision 5MP 40m IR cameras (max power consumption 0.5A/camera) and I'm using 8mp video baluns and cat 5e cable UTP. Used outdoors. The lines appear on 2 cameras powered by the same power supply, being at 35 meters/ 25 meters away. But only on one of them these lines seems to be more visible (the 25 m away one). I have to mention that all power is supplied from the same cord. I am using 3 pairs for the power supply for the affected cameras and still have the issue so I dont think its voltage related. Here is how this situation looks: https://www.dropbox.com/s/8cichfr3qks435z/screen_recording_20210523-225806_hik-connect.mp4?dl=0 For some reason, if I take a screenshot not all the lines appear. What do you think it is?
  3. New here...I have a dilemma and here is some background. We have a location where we need a security camera. That location has a Ubiquiti NanoBeam powered by a Ubiquiti switch putting out passive 24v dc. We also have a Ubiquiti Outdoor NanoSwitch there to split up the ethernet that also supplies passive 24v dc. We are trying to keep things simple and go strictly POE, not run dedicated power to a 12v dc camera. 1.) I cannot find an outdoor camera that runs on 24v dc, is one available anywhere? 2.) Is there a ethernet splitter that will drop voltage from 24v dc to 12v dc? 3.) Am I screwed? LOL I would REALLY like to just find a 24v dc camera... THANKS for ANY help you can provide!! Paul
