Hi All,

I purchased 3 x 2032's and an NVR off ali express over a period of about a year, starting around 2015. The cameras are POE via injectors and a chunky 12v power board I bough, and are run directly into the back of the NVR.

I have had the system running for the past 1.5 years, but with a reoccurring problems - the cameras will randomly hang. This usually happens at least 3 times a day, and can happen to any camera. Sometimes the cameras will randomly come back online after an outage of a few hours (ie this weekend, one camera went offline, then came back after about 8 hours). To fix the cameras, I just need to unplug them from the NVR and plug them in again, and they will start working (ie. dont need to be power cycled)

To date I have been managing this issue by running the power board off a wifi power switch that I can either manually toggle, or schedule to turn on/off every 3 hours. However, the relay is gone on it an I just want the problem fixed! Things I have tried:

Running directly into a switch, setting ip's fixed
Factory resetting everything
Isolating cameras external to the NVR, see if they hang if not recording (they do)
Changed switch<
Changed router

Ive attached some screenshots of my setup - any help would be appreciated!

Did the seller tell you if you should/could update the firmware?. Otherwise if you look around in the menus you'll prob find some Chinese words in some well hidden places that they forgot to translate that's an other way to tell. Hmm this was my best guess of the next step you could take to solve it. ... You don't have much too loose I guess. But you'll probably get a bunch of more clever answers if you wait a bit.

That's a bit of a contradiction - - PoE uses 48v nominally - are you running 12v up the cable with 'passive injectors / splitters' ?
If so - you may have marginal power due to drops in the cables when it gets to the cameras. You can only runs a few meters before you start to get out of spec with passives.
If that is the setup - maybe get an 802.3af active PoE injector and see if it makes a difference to the problems.

Yes sorry, got that bit wrong. I've got passive injectors / splitters sending 12v up the cable to the camera, which is then split at the other end and feeds the 12v into the female DC pin on the camera.
 
Funny you ask that. I can't seems to enable Poe on the NVR (it's not an option on the menus), so I went the splitter route instead. Am I missing something?
 
Nothing to enable - it's automatic, just plug the camera in and it should just work.
That's assuming the cable is OK - PoE uses the 2 unused pairs that are not used for data on a 10/100Mbps Ethernet connection. So you need all 4 pairs available. But that's normal, nothing special.
A straight cable, no splitters at either end.
 
Pretty sure I tried just plugging in but they didn't work. I'll try again tomorrow. I'm assuming cables are fine because splitter would us the Same pairs?

Probably true. You may be able to see the wires in use at the connector ends if you look carefully with a magnifier.
How long are the cables, do you know if they are pure copper, or CCA? (copper clad aluminium, fine for data, less fine for power).

If you do re-try it - you need to remove the splitter at both ends, leaving just the cable between the NVR and camera.
And watch the lights on the NVR PoE ports to see if there is any activity.
 
Thank for your help,

I'll check tomorrow...fingers crossed. I'f your right I'm going to do an epic face palm.

There are several ways to tell:
1. From the NVR, Menu, Camera management. Look at the camera serial number. If you see the letters CCCH, it is chinese. If you see the letters CCWR it is "World Region" (US). Not sure if you can see the S/N with a switch though.
2. Via a web browser, connect to the NVR, then to the camera (not sure it works with a switch). After login, click Configuration, System. In the screen capture below, I circled the CCCH indicating it is a chinese camera.
2. Connect the camera to a computer with an ethernet cable, power the camera with a separate power suply (you already have one) and run SADP. SADP will reveal the serial number.

OK, so checked the camers

1. DS-2CD2032-I0120131023CCRR438311918
2. DS-2CD2032-I20150125CCCH501697787
3. DS-2CD2032-I0120130701CCRR426046730
