NVR DS-7604NI-K1-4P(B) rebooting same time every night

[tedted22]

For some reason, and I just cannot figure it out, my new DS-7604NI-K1-4P(B) reboots itself nearly the same time every night.

See the last 2 days alert I receive by email:

EVENT TYPE:    Video Signal Lost
EVENT TIME:    2019-01-29, 03:08:15
NVR NAME:      Network Video Recorder
CAMERA NAME(NUM):   Front(D1)  Back(D2)  Garden(D3)  Side(D4)

EVENT TYPE:    Video Signal Lost
EVENT TIME:    2019-01-28, 03:06:52
NVR NAME:      Network Video Recorder
CAMERA NAME(NUM):   Front(D1)  Back(D2)  Garden(D3)  Side(D4)

and so on. Nearly the exact same time.

I've tried rebooting the NVR manually at random times but the 3AM reboot persists. Even factory reset a few times.

I have 4 x 8MP camera's (2385's) and when it's not rebooting itself it works great.

I was on 3.4.99 firmware but tried upgrading to the latest, 3.4.101 but no change in behaviour. Camera's also upgraded to 5.5.8.2 the other day but again no improvement.

Any idea's before I declare it faulty? (but why only 3AM!)

Thanks

It's an odd one.
Do the NVR's Logs show any anomalies?
Is it showing a power loss at that time each night?

 

[tedted22]

Yeah, it's definitely rebooting fully rather than a network outage.

The NVR log shows "Abnormal shutdown" and then its totally fine again all day until around 3AM ish the next morning!

Can you eliminate the mains socket / circuit as a possibility?
i.e. move it upstairs/downstairs/to the kitchen circuit to test.

Otherwise, send it back to your supplier, and let them run it overnight to see what happens.

Hello tedted22,
I have trouble with the same problem. Did you manage to solve it somehow? Many thanks for your reply.
