1. Camera Installation
1. Hardware Installation
Electrostatic Handling
The camera circuit board connects to the Raspberry Pi via a 15-pin ribbon cable.
Lift the clips on both ends of the connector.
The blue marking should face the network interface direction.
2. Software Installation
Modify the Raspberry Pi configuration to enable the camera module.
sudo raspi-config
Camera module detection

Currently, three applications are provided:
•raspistill captures images•raspivid captures video•raspistillyuv captures images
raspistill uses the image encoding component, raspivid uses the video encoding component, and raspistillyuv does not use an encoding component but directly outputs YUV or RGB from the camera component to a file.
