NVR Starts up then shuts down and beeps?

[DavidMalan]

I got my NVR today, installed a HDD, and powered it up. IT starts on the bootup screen (says NVR), but will not take me through the initial setup process, then the monitor shows nothing like it has been disconnected and it starts to beep 4 times. It beeps 4 times about every 20 seconds or so.omegle xender

What is the make/model? What did the manufacturer say, when you contacted them?
