Dual-channel — configure as TWO Frigate cameras: panoramic = channel=1 (3840x1080, 32:9 — set detect to 1280x360 to match), PTZ = channel=2 (2560x1440, rtsp://{user}:{pass}@{ip}:554/cam/realmonitor?channel=2&subtype=0, detect 1280x720). For ONVIF autotracking on the PTZ channel add 'onvif: {host, port: 80, user, password, autotracking: {enabled: true}}'. ONVIF PTZ confirmed working — Channel 2 profiles have both VideoEncoderConfiguration and PTZConfiguration (no split-profile issue, unlike SDT4E series). Verified in frigate#22135. Note: powered by DC 36V, not PoE.
