What’s going on here? My NVR and cams will run fine for a couple of days and then out of the blue, one will go black, when I look on the monitor connected to the NVR, I see “log in return time is up”. Only way to fix is unplug the ethernet cable and plug it back in. Then it runs fine for a few more days. Happens on 2 different cams, both are HFW4300C cams. I have other HFW4300C cams that don’t do this. Any ideas?

Yeah that’s about all I could find on it too. Wish they were more specific.

some updates, cam went blank again today, so instead of unplugging and plugging it back in, I tried some troubleshooting. I am able to log in to the web interface of the cam and see all the settings. The live view of the video screen says “resource is limited, open video failed”. Also looked at the log and it looks like its logging in and out repeatedly.

That didn’t help much in my case, It works fine on the IE browser when it’s working on the NVR. Something about the login time bugged me so I set those two cameras on a separate login name and password to the NVR, maybe there are too many cams on one login. I’ll see if that works.

Hello Guys!
Dan from evosec here (nope, we’re not affiliated with DAHUA, but we do provide solutions based on their hardware… and our knowledge
).
Usually “Log in return time is up” is linked to network problems – firewalls, port forwarding settings, restrictions, maybe malware or some bad hardware etc.
Try to isolate the surveillance system and do it only only-TCP-wise.
I doubt you will ever have problems again…

Lol! Well, it gets a lot of attention from/by searches.
So, you’re one of those that in 4 months after you get “erased” will become a zombie?
By the way, thanks for taking your zombie time to prove that my time is zombie-wise-somehow… Nice

sounds possible, but why wouldn’t any of my other cams be doing this then?

I’m pretty sure they are all setup the same, main stream to the nvr and a sub stream for live. I’ll check them though.

What’s the outcome of the check? Figured out the problem?

Nope, still just unplugging and plugging back in the Ethernet cable when they quit on me.

The usual suspects apply…..
- Reboot Camera
- Reset Defaults
- Disconnect from internet and run cameras using only an internal private network.
If 1 and 2 don’t fix it. Try 3. If that works out, make sure ports to camera are not forwarded outside of the private network.
If you have trip wires or intrusion set up, turn on live view to make sure camera isn’t arbitrarily tracking something it shouldn’t be. My camera would track a light pole for some reason if I had it at a certain angle. The light pole never moved obviously but the green box remained fixated on it. Maybe the camera was chewing up resources tracking something that was of no consequence. Ended up tweaking the angles ever so slightly until it was happy with what it was seeing.
Last but not least, try turning down the frame rates and disabling any un-used sub streams.
As pretty as some ridiculous high frame rates are, it puts more stress on the cameras cpu tracking abilities if you got 8Mbit streams trying to pump out 60 frames / sec etc……keep it real when it comes to recording.
