Two Clever Dog security cameras (Burridge SO31)

These both use a free app, you’d need to put a micro sd card in each (ideally high endurance ones as these are designed for CCTV).
Both need a usb to micro usb charger which most people have already but are cheap to purchase.
One is a fisheye one the other a normal camera.
Both need resetting but this only requires a pin.
Good instructions available on the internet for these. To go together ideally.
