  1. Hi I am about to purchase a cam system for my hm and shop the distance between the two is 200ft my concern is stray voltage induced it my cabling from other sources I am not sure which cable to use Rg6 would be preferred due to size and being more flexible and the fact there is already 1 1/2 pcv conduit in ground, In the back shop I have a milling machine with a 3 phase converter in the front I have a 1750hp Eddy current chassis dyno my question is how far away from these devices does the cable have to be ? [of course at night they are not in service and during the day only part time ] and how far away from 110v romax wire i have read not to make runs parallels to high current My conduit is installed with a run in the hm right next to each other for 3 ft my equipment is about 15 feet from any camera or cable run i plan but i must pass over 110v wiring how far away from the 110v do i need to be ? I need to run for 8 cameras into the shop and around the building should I use shielded wires wireless is out of the question any thoughts would help . thanks Royal T
  2. I have a 21 camera setup (Dahua A511K02 Lite Series HDCVI 5MP), all cameras are crystal clear in daytime. At night, when LED flood lights come on, (4 out of 5) parking lot cameras have waving interference lines. Of the 4 cameras, some see the LED light and some don't.. same interference on all 4. How can i remove this interference? Video links, with and without flood lights on.. https://www.dropbox.com/s/d0q4jxwdwcyahtv/20211112200632.mp4?dl=0 https://www.dropbox.com/s/rvzoj48edwsp763/20211112195510.mp4?dl=0
  3. 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?
