I just got the "COMPLETE 32 CHANNEL DVR ULTIMATE SECURITY CAMERA PACKAGE" and I hooked up one camera  just to make sure I got a feed. It worked fine but then the system started beeping. I had the top of the DVR case opened up because I was installing the hard drives and I notice a red LED at location LED9 amongst the blue and green ones on the board itself. It is right next to the little round siren component that was making the noise. I logged in to the system which I thought might stop the noise, but it didn't. I'm not sure what the problem is. The tone isn't constant, it's about a half second beep every couple seconds. Any insight would be much appreciated!
