Stream live video from one Raspberry Pi (with camera) to another RPi (base station) over WiFi/TCP.

sudo apt-get update && sudo apt-get install -y python3-opencv python3-numpy python3-picamera2

The base station doesn't strictly need python3-picamera2, but it won't hurt to install it.

python3 receiver.py --port 9000

This opens a listening socket and waits for the camera Pi to connect.

python3 sender.py --host <BASE_STATION_IP> --port 9000

Replace <BASE_STATION_IP> with the base station's IP address. To find it, run hostname -I on the base station Pi.

Press q in the receiver's display window.

Example at higher resolution:

python3 sender.py --host 192.168.1.50 --port 9000 --width 1280 --height 720 --fps 24

On each Pi, run:

hostname -I

• "Connection refused" — Make sure the receiver is started first.
• No display window — The receiver needs a display (monitor, VNC, or X forwarding).
• Camera not detected — Run rpicam-hello to verify the camera works.
