Andy asked me to test this with the 5241-Z12E and
Blue Iris since this has a new encoding strategy and we know that Smart Codec can be problematic with Blue Iris.
Personally, I have never had an issue with the AI in these cameras and have always been spot on, and believe in the don't fix what ain't broke mentality, but thought I would give it a try on the older model camera.
First thing I noticed when I updated was it asked for a plug-in. Thought those days were gone LOL.
When I changed it to the AI Codec, it now forces your to use iframe interval of the FPS or twice the FPS - those are the only two options.
Fortunately I have a few runners and walkers go by like clockwork so I could pull them up from previous days to compare.
I have ran it for 24 hours now and it all appears to be running fine with Blue Iris, with an exception that may or may not be an issue for you.
With SMD, the recognition of the subject is delayed compared to previously. I suspect that is in part due to additional analysis being performed. It still recorded on every event, but in many instances, the vehicle would have moved all the way across the screen and be half a car from outside of the field of view all together before the vehicle would get the AI box around it (so actually a half a box). Previously it would draw the box around the whole car when it was in the center of the frame.
I do not know if this update also impacted IVS AI, but it did in mine. Similar things happened as with SMD. Previously, the camera would trigger on the leading edge of the box around a person. Now the person is completely through the IVS before it would trigger. It still got them and triggered, but was delayed.
This impacts if you use it as a spotter cam for a PTZ. The jogger would be almost out of the field of view before the IVS triggered well beyond the jogger crossing the line right in the middle of the field of view. This impacted the spotter cam in that by the time the camera recognized it as a person and sent the command to BI for an ONVIF trigger and then the PTZ would move, the jogger was out of the frame. This did not happen previously.
And here is an interesting issue. Switching back and forth between SMD and IVS changes the shutter speed and iris. I am enabling and disabling right now and watching the screen darken and then go into the exposure and I am watching the shutter speed and iris change. IVS is a 6.66ms shutter and 70 iris. Change to SMD and it goes to 8.33ms and 95 iris. Switch back to IVS and back to 6.66ms shutter and 70 iris.
It will be interesting to see what results
@Wildcat_1 gets with this camera. I am so happy with the AI performance on my 5442-Z4E that I am not risking this update for it. I will give this a few more days on the Z12E and maybe try 3 factory resets LOL and see if anything changes.
