Looks great bp. Watched them at 2160p full screen.

The 6Mbps maximum bit rate should be OK due to the frame rate limitation.  I'd want a higher bit rate to run 10MP at, say, 15 fps, but at 6 fps max, it should handle the encoding ok.

Sounds like the cam's CPU is marginally powerful enough for 10MP, which makes sense, given the low price.  It's probably the same CPU they use in the lower res cams. 

How's BI's CPU load look when running 10MP?

I've got one of these on the way, and am looking forward to putting it through its paces.

As I mentioned in

It adds 4 to 5% to the total blueiris.exe CPU usage on my i7-3770k, with direct-to-disk enabled.

8-10% with direct-to-disk disabled, which you may seriously consider doing since the OSD is so remarkably bad on this camera.

Indeed the timestamp OSD on my D32 cameras sucks. It can not be read because it's so small.

Yes...the timestamp on my Acti E33 is so small as to be next to useless. The night image isn't very good either. The day image is very good.

It is really bright outside and I notice the ACTI is having trouble with that.  It is quite blurry and it would really be nice if the WDR setting did anything at all.



For comparison, here is the same location capture by an Ubiquiti AirCam:


And by my silly Chinese EC-IP5911P camera:


I think the blur in the ACTI image must be caused by extremely short shutter speeds.  The only thing that is in focus is water droplets falling off my roof just inches away from the camera.  I guess the camera could use an Auto Iris :)

Well, that's ugly!  It looks like the focus has shifted.  You can see the pixels (or something that looks like them) pretty sharply, but the image is all blurred out.

When it's not bright, does it go back to a sharper image?

I think so - it is still bright out :)

Also I have DNR on which adds a lot of artifacts around the edges of objects.  If DNR is off, the image doesn't get any sharper though :)

Here are some pics of water droplets in midair.  There have been bigger and rounder ones, but I haven't managed to capture one yet :)






Also, it is even brighter outside now.  Poor chinese cam:

The water droplets look great!  Look like your focus has shifted to much nearer.

I got my E77, but haven't unboxed it yet.  I'm waiting for 36 hour days to start...

I've always wanted an extra 24 hours each day (during which I did not have to work or sleep, of course).  But an extra 12 would do.

FYI everything is sharp again once the light gets a little dimmer :)

Well, that's interesting.  There have been a few cases of Dahua cams shifting focus when the sun is on them, including one of mine, and it's not clear whether it's heat related (seems unlikely in your case), or something else is going on.  I guess I'll unbox it this weekend.

If you can post a sharper version of the same view, that would be interesting.

There are quite a few sharper pics in the first page.

Well, that really looks like a focus shift.  On a non-motorized focus/zoom cam, that can only come through a few things:

- Lens to sensor spacing changing.  This can depend on how the lens focus is locked and how the lens holder is mounted to the sensor board (often as part of the IR filter).  It's pretty rare for the lens to actually turn in the holder, but stuff happens.

- Lens elements shifting within the lens.  I've had a few rattly lenses in my day, and a lens that worked well through QA may have had elements loosen up during shipping.

There's a bit of chromatic aberration (purple fringing) on the lens, but that's not uncommon on M12 lenses, since it costs more money to make lenses without it.

I'll be tearing mine apart and taking pics at some point, but should probably test it a bit first.

ETA: It just occurred to me that software could cause an apparent focus shift as well.

Assuming the lower resolutions show the full FOV, or something close, they are likely to sum and average adjacent pixels to get the larger pixels that would make up, say, a 720p image.  If it were displaying averaged pixels in 10MP mode, this would look just like being out of focus.

I'm not sure how you'd test something like this (maybe reducing the 10MP image to a smaller resolution, though that should give the impression of better focus anyway), but if the mechanical components are solid, a software glitch makes some sense.

are you using BlueIris for this camera?  Is so, what config are you using?  I seem to have a major delay in the video refresh

I will post screenshots of the appropriate config areas from the camera and BI tonight.
