# systemd service for the SONIC composed camera server.
#
# Publishes JPEG-encoded camera frames over ZMQ so the data exporter
# (on the workstation) can subscribe and record.
#
# ── Setup ────────────────────────────────────────────────────────
#  The install script can generate and install this automatically:
#       bash install_scripts/install_camera_server.sh
#
#  Or manually:
#  1. Edit USER, HOME, REPO_DIR, and the ExecStart command below.
#  2. Copy to systemd:
#       sudo cp systemd/composed_camera_server.service /etc/systemd/system/
#  3. Enable and start:
#       sudo systemctl daemon-reload
#       sudo systemctl enable composed_camera_server.service
#       sudo systemctl start composed_camera_server.service
#  4. Check status:
#       sudo systemctl status composed_camera_server.service
#       journalctl -u composed_camera_server.service -f
#
# ── Finding your device ID ───────────────────────────────────────
#  OAK cameras:
#       python -c "import depthai as dai; print(dai.Device.getAllAvailableDevices())"
#  RealSense:
#       rs-enumerate-devices --short
#  USB:
#       ls /dev/video*    # use the index number, e.g. "0" for /dev/video0
