Conclusion: All three cams have focus problem when heated during video recording. Furibee cam shows the worst result the other two are slightly better but some fine details bluring occurs.

good test so far...

yeah, i first noticed this problem in in October (or maybe November) in my F60B crane imx179 from Gearbest. I gave that cam away weeks ago. and the external power source more quickly heats the cam. but my andoer fuxin imx179s seems to stay in focus, even when it's inside the waterproof case (without vents / slits).

or MGCOOL ES - https://www.gearbest.com/action-cameras/pp_619266.html ?

[nutsey]

Ehmm... The first one is $53.41 and the second is $40.14...

nutsey - I'm in Thailand now. so my IP address is of Thailand. Would your location and/or IP address effect the prices on sites?

[nutsey]

Seems to be pretty reasonable explanation of such price difference

[petesimon]

By the way, some Q3H-2 cameras (but without the white LED at front) shown in the videos are very similar to the Tomtop D4876B . My D4876B and if I recall right ... and some Q3H-2 are both Fuxin inside .

I flashed late 2017 Beike firmware to my D4876B cam and this replaced the original Fuxin fw. The cam seems to work fine and has FOV, Motion Detection and lower ~22Mbps bit rate instead of ~31Mpbs for 1080p30fps.
