  1. 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
  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?
