Pi Camera Module
The Pi camera module is a portable light weight
camera that supports Raspberry Pi. It communicates with Pi using the
MIPI camera serial interface protocol. It is normally used in image
processing, machine learning or in surveillance projects. It is commonly
used in surveillance drones since the payload of camera is very less.
Apart from these modules Pi can also use normal USB webcams that are
