MIC2182YM

Received in 25 days. Stitched through the USB-TTL for 3,3 volts and arduino ide. Works. While only tried as a wi-fi camera, then i'll try bluetooth and as a video from the camera to write to a memory card. It is a pity that the thread setting sharpness is fixed with a drop of varnish or epoxy, but this is fixable if you need to adjust to a certain distance, or object. After the firmware, this module can be built somewhere and after the power supply to it, it connects to the wi-fi network for a few seconds and starts to transmit the image. I think you can do that if there is movement, it will wake up and start broadcasting and (or) recording to a memory card. There are more features than esp8266 or arduino. About $8 is a great price for such a powerful fee.
