hadn't heard of that issue. It's two cameras on 1 POE port so it's rated for 802.3at power. not 802.3af power.

I don't know that garbled video is common. Earlier in this thread it was reported by at least one other person (but i see now that it was for a Color4K-T not Color4K-T180). I remember seeing it in a few other threads too, but don't have access to them right now.

To clarify a bit, yes, that GUI I posted is from BI. Based on the suggestions from earlier in this thread, I made sure to use H264 and the result is the same. I can replicate it 100% of the time by switching on one of the backlight modes such as WDR or HLC. If all dynamic lighting modes are off, then it's fine. Also, this seems to only affect the main stream since the overview in BI never shows garbled video. It's only when viewing the camera in single camera mode (which I assume is main stream) that the video gets unusable.

Do you restart the cams in Blue Iris after you make changes to the settings in the cam?
 
Found the other post where this issue is discussed. Seems it's not specific for Color4k-T180, but any models using WizColor processing. What I'm seeing almost exactly match the conditions mentioned in that post. Observations from steve1225 seem to be spot on and clarifies things quite a bit.

Thread 'Bug in IPC-Color4M-T firmware?'

I recently purchased four IPC-Color4M-T cameras from EmpireTech and think I may have found a bug in the firmware. The cameras are all running V3.140.0000000.10.R, Build Date: 2025-02-26.

Here is what happens... When the cameras are set to "Day/Night switch" their video feed stops for a little bit causing it to disconnect from my NVR when it switches between Day and Night modes (typically at dawn and dusk). Notably, this only happens when I have Day's backlight mode set to WDR or SSA (I haven't tried the other settings) and Night's backlight turned off. (I will also note that Day's AFSA is...

Solution is to avoid using WDR/SSA.

For the record, yes, restarting the cam in BI fixes the issue until the next time WDR/SSA is enabled. This means you can't use different backlight settings for profile switching between day/night.

So do we call that a +1 for NVR’s

Nope because the OP thread mentioned above is with an NVR. Now bigredfish has an older NVR so maybe that is part of why he doesn't have a problem?

Or there is something else going above with some other type of codec that he isn't using.

I suppose I missed that, I just saw something about restarting the cam in BI a couple posts up. As well I probably should have added a smiley face or something to indicate I was just being a smart ass.
