    What chips are used in devices like this? There are some boxes for model planes/helicopters that perfrom similar “video-to-wifi” bridging to use with iPhone/Android, so I am wondering how they are made? Is it ralink/mediatek AP solution with usb video? Or something with digital CMOS video input?

    I don’t know. The best would be to open one. I can see you can buy the Wi-Fi and USB microscopes above in Aliexpress:

    The Wi-Fi version ($199) seem a bit too expensive compared to the F.O.B price announced ($100).

    This is something similar:

    But chip marking is hard to see. I believe the BGA is something like Ralink RT5xxx AP chip, with some kind of video interface in the smaller tqfp on the left side.

    I’ve just remembered I have a Wi-Fi IP camera. It’s using an HiSilicon Hi3512 (ARM9) + OV7725 sensor. I’m not sure about the Wi-Fi module.
