Review-Dahua IPC-HDBW4231F-E2-M Dual Starlight Cam
- Thread starter looney2ns
- Start date
Took a quick look: No apparent change.
Neither backlight mode for channel 2, nor simultaneous IVS. For the latter I don't think there will be a fix, as the CPU of this thingy is probably to slow to analyze two frames at the same time. However, why backlight compensation isn't separately selectable is beyond me.
For me, this thing is a toy, without any practical value with the severe limitations it has.
(As a sidenote, I could not make it show any image on any browser on Mac, neither Safari, nor Chrome, nor FF.)

Getting the hang of it
Yep. No change on my end either.
In addition, I had to set the IVS parameters on channel 1 through the NVR. Not ideal, but that was my only workaround. Channel 2 isn't available whatsoever in the IVS parameters. I can click on it, but nothing even comes up.

@EMPIRETECANDY
New issue. Buddy has 5 of these cams, 1 has been acting up for a while, now having another issue. Hooked up to a Dahua 4k NVR.
Here is the cam log. Here is what I think is going on: LOG HERE Index of /dave
NVR has IPC Time Sync enabled. Also, cameras have NTP time server enabled.
Every 2 weeks or so, 1 camera in system becomes unresponsive until power cycle. A message appeared on the nvr for that cam that said something like login timeout then it became inaccessible even by ping.
Looking at log it appears a few hours before connection was lost the NVR attempted to login and set time repeatedly every minute or so until the camera lost connection. The log showing this is attached. This started at about 5:51PM in the log and the camera crashed at about 7:56PM. Looks like the camera is still alive after that as there are motion events before the camera was unplugged and power cycled at 10:27PM. Looks like the network connection was just lost. I dont know why the NVR was continuously trying to set the time though.
Today he had a different camera go offline..... he writes The first camera that went out was the lowest, 192.168.1.101. Then .102 went out. Seems strange.
Anyone help? Thanks

What is his NVR model? Drop line mostly because of the not stable power/power cable. So the problem maybe the NVR or the cables. Can try some other power to power it or test with some new cable.

The NVR is the brand new (few months old 4k, s2, non POE nvr. ) He has a cisco 16 POE large switch.
He tried a small cable, lasted about a week on the test bench, with the same result. Hes also tested other POE ports. He has the same camera and the front door, and its working great, even at a distance a bit farther from the one that cuts out.
It baffles me
Hi everyone, I just installed this baby on a PFB203W. It fits fine.
Now I have to figure out how to get both streams on my 4108 NVR.... [ I am still new so figuring out how to manually add etc... ]

I tried those but couldn't get it to work. One of the issues is that I get different options and screens depending on whether I use Mac (chrome), Windows (Chrome), Windows (IE - this won't even work!), or directly on the NVR which is tricky because I can't find my wireless mouse....
Maybe I need to upgrade as Dahua calls it; (update) my NVR.
Even with the latest firmware two issues are still present. SmartIR settings reset after reboots and channel 2 remains in B/w mode during the day.
Just a quick note here: i received one of these last week and installed it yesterday after a week or so of testing on my desk.
After installing it-- it stopped working. I did put the POE cable in a tight pinch when screwing it in-- though maybe I broke it. Couldn't ping it-- POE lights were on.
Ends up-- must have held the reset button down when installing and it defaulted to the default IP. Thanks to Andy for his help....

That original night video-- was the IR light genereated by this camera or the one next to it.
I mounted mine and the angles are large on camera 2. I think I am getting IR reflection from the case at night. Maybe ill take the cover off some night to see if it gets better without it. Thinking of getting external IR lighting...

@looney2ns would you recommend this camera? I read something about no backlight for the 2nd cam and no IVS? I plan to use this with an NVR if that matters. It's for my mom's new house. I may try to convince her to use blue iris but that may be a stretch.
Good question. I have one installed but I value @looney2ns opinion as an experienced camera punter.
You are correct, it appears with the latest firmware that any back light settings, must be done for ch1, and that setting gets set for ch2. You can't adjust ch2 separately.
IVS will only work on one channel at a time.
The IR is weaker than a turret would be as well.
I've had it up in use for several months with BI, and other than that, it's a fine camera.
