Review on 🔌 ANNKE 4 Pack 30M/100ft All-in-One Video Power Cables for CCTV Security DVR System Installation - BNC Extension Surveillance Camera Cables with Free 4 x BNC & RCA Connectors and 100pcs Cable Clips Included by Marc Hawkins

I bought this product because of the good rating. After spending an entire weekend installing my security system and using these longer cables, I thought it was fine as the security system I bought only had 60ft cables and I needed several 100ft cables. I bought a Samsung security system and the first time I set it up everything was fine until one night my system started beeping because I was losing signal from several cameras. Turns out that after several days of troubleshooting (removing and replacing the security system), hooking up a new one to my cameras and the same, the electrician found out that these VERY CHEAP CABLES lose signal at night because they have to think about copper wire, and more voltage is required at night with infrared night vision. Therefore, half did not work at night, but usually during the day. So I had to go back to my attic and remove all those cables that Revain bought and replace them with new, thicker 100ft cables so there would be no voltage drop across the cameras at night. After testing, all cameras work as they should. These cables MAY work well if you place them in a location where it is NEVER DARK and where night vision is required.
