@hidefvideo Thanks for the great teardown photos. That confirms there are two models of the v1 sold by Wyze. I got two v1’s at that were ordered on Jan 18, 2018, and although I haven’t dissected them, I know they are different than the v1 cam you have, since mine had 4 LEDs, like your v2. Also, I wonder if mine also had the same audio chip as what is in the v2, because my cameras have the “helicopter”, or “sprinkler” noise profile. And LikeWise said in
that v1 can have Ocean wave sound, and v2 can have the “chirping or helicopter” sound, which both my v1 and v2 cameras have. I am wondering what the (Q12) three terminal SMD chip is. It could be a power regulator, or transistor (for FET). It may be involved with the sprinkler aka chirping aka helecopter sound. But someone would have to probe with an oscilloscope to know for sure.
Several observations: It looks like the v2 no longer have a light sensor (Q2) which may be one of the reasons that mode switching behavior is different. Also there is another missing chip (U49) but perhaps it was just moved to the other side of the board (U13) next to the (J21) power connector. My guess is those are flash memory chips.
The fourth picture down showing the SOC (System On Chip) or “processor”, the circuit board one on the left has an earlier date code than the one on the right.
Left 2017-09-06, Right 2018-03-02. If I am interpreting the dates correctly as ISO 8601, then the right board must be v2.
The little green boards are the wifi chip modules.
Earlier pictures I have seen of Xiaofang camera guts showed that at one time there was an unpopulated PIR (Passive InfaRed motion detector) which was probably eliminated and delegated to the processor in a Xiaomi cost cutting design change.
Another thing I notice is that every picture of the lenses shows a distortion pattern on the v2 camera. I suppose it could be something in what is being reflected, but there are several pictures from different angles, so that makes me think it is something to do with the lense.
Thanks again for the detailed pictures.
The paint job looks fine to me. It reminds me of the type of the textured finish that was on my dad’s toolbox. If it was too smooth it would more reflective.
