asmikle1 on CCTV Camera cycles on and off at night only

Hello,

I have three cameras (all Honic model HN-IA60E200FS) that work great in daytime but at night they constantly cycle on and off (see image). I use a 12V 5A power supply separate for each. The DVR is the Tridvr ELE8 (2015). I have 5 other camera that do cycle also but only a few times them stop. What do I need to do. I recently purchased a new system from SecurityCamera Kings but not sure if it will do the same thing (Order# 438312).
