Hi all, I have a NVR5416-16P-4KS2E NVR and a bunch of IVS-capable Dahua cameras. The system has been running great and doing motion detection recording without fail for over a year now. Unfortunately, I have never been able to get IVS recording working properly. Yesterday I updated to Andy's...

I've posted an entire thread discussing the issue here: NVR5416-16P-4KS2E ... was working ... now all cameras disconnected I ask if this particular issue is resolved because through discussion with Andy, we now suspect that the issue in my case is a faulty POE board in my NVR. Andy's sending me...

Did you end up resolving this? I am potentially having the same issue with the 5216. POE tab shows power but there is no network connectivity to the cameras.

Hi Chris, thanks for that information. I did not know that it was intentional that devices on the switch ports could not talk to each other. If that's the case, then I suppose it's working as intended. I did try changing the internal subnet to something else but also with no luck. Previously...

Spent another night playing with this and I think there is nothing left to do. At this point the only explanation can be a bug in the firmware. Without shell access I cannot debug how the unit itself is routing between switch ports. I reset the NVR again. Tried to see if the NVR was saying it...

Hi Chris, yes -- I took it a step further. That screen, when accessed directly via the NVR, has a Factory Reset button. I did a full Factory Reset of the NVR and there has been no change. I feel the only way I can resolve this is if I can get shell access to the NVR. But there is no...

Out of desperation I also just upgraded the NVR firmware from V3.216.0000002.0 to V3.216.0000004.0 (latest available on Dahua's website). No change.

Well, the saga continues. I need some serious help! This is driving me nuts. I've done some troubleshooting and I can now say the following is true: All the cameras work fine. I connected each camera to my regular Unifi POE switch, plugged a laptop into the same switch and assigned a static...

Thanks everyone for the suggestions. I did not consider plugging a laptop into the POE ports. But, this would allow me to test DHCP assignment on the NVR "switch" side and also have a route to the individual cameras on the 10.1.1.0/24 subnet. Further I can try the Dahua Config Tool without...

Hi all, I recently bought and installed 10 Dahua POE cameras powered and controlled by a NVR5416-16P-4KS2E NVR. For several days the cameras were working great. I was able to access them via the gDMSS Plus app with no complaints. The other night, for no discernible reason, all the cameras...

:facepalm: I see! Okay, then POE splitter it is...

At the risk of sounding like a dummy, I'm going to throw this out there in the event a) I'm understanding the spec sheet correctly, b) this would actually work, because c) it would be really neat... I see this microphone has been used successfully with a POE splitter in a few threads here...

I think you are correct. I misinterpreted the "A" as meaning it had a mic. In the Dahua comparison tool, models with audio in/out are distinctly different from models with built-in mics. I didn't notice that...thanks for pointing it out. If a model has audio in, is that simply a 3.5mm jack or...

Well, thank you guys again. I had a suspicion that PPF didn't seem right...certainly the videos posted here looked way better than 44 PPF! I didn't see that some cameras have the option to configure the zoom in the calculator. That is tremendously helpful and makes a big difference in the...

Thanks everyone for all the insightful comments! Hmm, perhaps automated LPR is unreasonable at night due to the compromise of settings on that camera which would make it useless for any other purpose. This might only be attainable with an additional, purposefully configured camera, and might...
