Hello guys, this is my first topic, hope that i`m posting it correctly to the right section. I have an issue with a Dvr system, the software used is ComArt Pillar latest win version and the board is a ComArt hicap50 with 16 cammeras installed, 12v power supply installed separately. I haven`t gone yet to the clients location but I encountered this issue before: The cammeras work correctly but from time to time the image on every cammera turns gray and fluctuates, black to gray, unfortunately this time the cameras shows this gray image continuously (in the past a simple power reset was working but not now.) Do you have any ideas ? I mean what`s wrong, do the cammeras don`t receive enough power ? I installed 16 cameras to another location recently and saw that with only 1 12v power supply the image on cameras are not smooth therefore I installed 2 separate 12v power adaptors to work each with 8 cameras. This is the case for the problematic location ? Sorry for my english, I would go directly to ComArt support but haven`t found yet the client code... Thank you in advance. Andrew

in an 500 square meters area 16 cameras all over the place. the electric cable that was used I think that it was 2x0.75mm but i`m not sure due to the fact that I haven`t installed it myself. I`ll check the power rates for that power supply in load and off load to see exactly how much power do I get in the circuit. Thank you
