Yeah, I agree 5Ghz doesn't make sense for a doorbell - the range is already lower in the higher frequency range, and you'll get more attenuation through the heavy materials like your walls/doors. But I guess it's another feature you can market.
As for H.265 it makes sense to use a better compression codec if they're increasing the resolution, although I'm keenly aware of the compatibility problems H.265 can present (I'm the guy who rewrote a lot of the Home Assistant stream component to handle H.265 and just contributed some PRs to Frigate to do the same).
So the main benefit of this camera over the DB1C is just the increased resolution? Same FOV/fisheye?
I didn't have the Db1C before, so not sure how compares. Video quality is pretty crisp and it does have fisheye.. Stream resolution shows up as the widespread, usual, and totally very common 2544x1888.
I'm using Frigate and the 265 is not working well at all, video is all mangled. Ezviz app, or VLC looks fine. In addition, Linux is a horrible mess for 12th gen Intel graphics drivers, they don't work at all and I've tried
everything including various GUC/HUC settings in the kernel along with latest linux-firmwares from Intel, and hand-compiling and installing the whole absurd libva/mediasdk/etc.. stack.
Man, that stuff is silly, I don't know how they can present "here are the 230 steps required to maybe get video acceleration working on Linux" with a straight face, then turn around and swear "2022, finally the year of the Linux desktop!".
Just played with it a bit more.. The cloud connection is surprisingly good, but the RTSP stream isn't good which is weird. Even in VLC it hangs and drops out quite a bit, while the app on my phone shows good, low lag video even when I shut off wifi and go over LTE.
Another edit - just confirmed the RTSP stream is busted, both VLC and tinycam on android and VLC on Windows show the stream as constantly dropping out, going gray, garbling, then coming back for a second or two, then corrupting again. Disappointing - I will mail the vendor and see if they can fix, otherwise it's going back to Amazon.
