Ah OK I see now. Literally no difference...hmm. guess I will hold off on upgrading since it breaks my other cams.

There is a new update out. 4.6.4.3. I wonder if this has any other fixes for h.265.
Just finished my first 1hr clip using 4.6.4.3 and not seeing much difference. The clip recorded fine, but with no reduction in size I rather stick with h.264. KEEP in mind I am using a I5 3rd gen. processor that doesn't support h.265.....so maybe it can't write direct to disk as it should. I would think it would only involve decoding. I asked Ken this and all I got was try the 4.6.4.3.

I had an idea. Not sure if it's correct but I thought I would share.

H.264: 24~9472Kbps H.265: 14~5632Kbps

These are the bit rates for the 5231R-Z. H264 dropdown for me maxes out at 8192kbps and H265 maxes out at 4096. So let's say I had it sent to h264 at 8192 well when I switched to h265 I would be forced to a max of 4096 (or slightly higher with custom setting) which would be the same quality as h264 at 8192 (that's a guess). So maybe space saving comes from being able to use a lower bitrate or getting better quality with the same bitrate. It would make sense that MPxFPSxbitrate gives you the same size file despite the encoder setting. So wouldnt it make sense that you did not change Megapixels, FPS, or bitrate so of course your file size remained the same! I think that makes sense?

Anyway I upgraded now. Running H265 now. Will report back tomorrow.

Ok, When I change mine in cam settings mine goes from 2048 to 1280 when I switch it to h.265. I updated to 4.6.4.4 and will try it today and see if the quality has dropped and post results later.

Just to update everyone H.265 seems to be recording correctly now in 4.6.4.4. No more grey or black screen. I do have an issue where by fps jump up to 30fps (and stays at 30fps) regardless of the setting but I believe that is due to the new firmware on the camera (2.460.0000000.16.R, Build Date: 2017-09-04).


It appears it is only effecting h.265 so for now I've switched back to h.264 to test if fps will stay constant on h.264.

Same here. It works fine here with h265 except for the 30frames which I also believe is caused by the new dahua firmware.

Yep 30fps issue affects H.264 also. Says at set rate (15 in my case) for a bit but sure enough it shot up to 30 at some point during the day.

Seems there is no beta testing for Dahua firmware before release.
Sure they do @looney2ns ! They have plenty of them (us). It's OK though. I just won't update My other cam. The one I updated will be my guinea pig. Hopefully they fix it relatively quick though.

Well I had the same grey screen issue appear today for about 2 seconds. I had some Jehova witness people knock on my door today and when they were walking away the screen went blurry for a sec. I'm on the current version of Blue Iirs (4.6.4.6). Guess I should just revert to h264 and be done with it.

Is the grey/black-screen bug for sure fixed in the latest BI (4.6.4.11)? I reverted back to 4.5.8.5 due to this bug. (I have not yet updated the Dahua firmware for the camera btw).

Yes I do believe so. I haven't seen it reappear. I had it happen once on 4.6.4.6 (for like 2 seconds) but have not have it happen since. I'm pretty confident the issue does not exist on 4.6.4.11. I went through many clips today and have seen no evidence that the grey screen issue occurs on any newer versions.
