-1. The server must be installed on a Raspberry Pi, with Raspberry Pi OS bullseye or newer as operative system, and must be installed by using the standard method (Docker is not actually supported). If you're using the 64-bit version of the operative system, you need to pick the `arm64` variant of the server.

+```
+docker run --rm -it \

 After starting the server, the camera can be reached on `rtsp://raspberry-pi:8554/cam` or `http://raspberry-pi:8888/cam`.
 
 Camera settings can be changed by using the `rpiCamera*` parameters:
