DVR Security Forum

I am a newbie to these forums so please bear with me...

I'm having problems with video quality when installing cameras to a GV1480 card. I install 1, 2, 3, 4, cameras and video quality is beautiful but when I add all 16 cameras to the system video quality is horrible. Lots of flickering and lines.

I figured there was some kind of interference but I can't figure out what it is.

I thought maybe it was the power supply so I changed it and am now using 2 power supplies.

Nothing improved.

It works fine for up to 4 cameras but as soon as I add the fifth the video quality is horrible.

Please help!

Hi, What Spec PC are you using?
What chipset, CPU, GPU, RAM etc

You are using 2 psu's?

Where did you get your Gv1480 from?

We have recently build 2 Gv1480 systems and have them both connected to control center and so far there has been no problems.

We purchased the cards from ezcctv and pc parts from Ebuyer.

If you can give some more information then maybe we can find a solution.
