Mini cameras maybe suitable for nestcam (Westmill SG5)

I hoped to use one or ather of these as a nestcam, but lost enthusiasn. Instructions with both.
The larger one has zoom lens 2.8-12mm and a bracket I made to fit a standard tripod. Needs 5.5 to 12V supply.
The smaller one claims 6mm lens and needs 6-12V supply.
