I'm getting really frustrated with my recently purchased NVR108-4KS2 from Empire Technology. After setting it up and going to work, it's online. But when I get back home, it's offline / locked up. Weirdly, I can still ping at it from my terminal with a good return, and I can view old camera images (not the current timestamp) on the monitor. If I try to access the menu with the mouse, it won't work. SmartPSS would say the NVR is offline.

The NVR is suppose to record two Dahua turrent cameras (one is 2mp, another is 6mp). They are connected to a separate PoE switch. The NVR has a brand new 2TB purple HDD. I've also uploaded the latest (June 2018) firmware into the NVR.

The IP addressing should be correct because I can access the cameras perfectly via openVPN and when I'm local. Both cameras and NVR have static IPs (192.168.22.200+) outside the range of the DHCP (192.168.22.100+). The gateway is set to my router's local IP (192.168.22.1) . DNS is Google's DNS (8.8.8.8, 8.8.4.4)

I've been hacking at this for a couple weeks now and I am getting really frustrated. I don't know what's wrong.

Does anyone have any ideas or experience? Thanks.

Have you ever set the NVR back to factory defaults, and started fresh?
Do you have it connected to a good backup UPS?

Hey Looney,

Yup, I've reset the NVR back to factory after the firnware update. I don't have a UPS but I rarely have issues with the house supply.
 
With a different NVR, I found if the camera bit rate was set to high the NVR would throw hard drive errors and reboot. Just a though.
 
Are you sure the POE switch is staying up, sometimes the power wart is not any good.

Provide a screen shot of the NVR camera configuration, address...
 
Completly different system, however, I have 1080p cameras bit rate around 4000 and 12-15 fps.
