What does this mean? To maintain object tracking during PTZ moves, Frigate tracks the motion of your camera based on the details of the frame. If you are seeing this message, it could mean that your `zoom_factor` may be set too high, the scene around your detected object does not have enough details (like hard edges or color variatons), or your camera's shutter speed is too slow and motion blur is occurring. Try reducing `zoom_factor`, finding a way to alter the scene around your object, or changing your camera's shutter speed. + +### Calibration seems to have completed, but the camera is not actually moving to track my object. Why? + +Some cameras have firmware that reports that FOV RelativeMove, the ONVIF command that Frigate uses for autotracking, is supported. However, if the camera does not pan or tilt when an object comes into the required zone, your camera's firmware does not actually support FOV RelativeMove. One such camera is the Uniview IPC672LR-AX4DUPK. It actually moves its zoom motor instead of panning and tilting and does not follow the ONVIF standard whatsoever. diff --git a/docs/docs/configuration/cameras.md b/docs/docs/configuration/cameras.md index 20bd7e48b..4555e8469 100644 --- a/docs/docs/configuration/cameras.md +++ b/docs/docs/configuration/cameras.md @@ -93,4 +93,5 @@ This list of working and non-working PTZ cameras is based on user feedback. | Sunba 405-D20X | ✅ | ❌ | | | Tapo C200 | ✅ | ❌ | Incomplete ONVIF support | | Tapo C210 | ❌ | ❌ | Incomplete ONVIF support | +| Uniview IPC672LR-AX4DUPK | ✅ | ❌ | Firmware says FOV relative movement is supported, but camera doesn't actually move when sending ONVIF commands | | Vikylin PTZ-2804X-I2 | ❌ | ❌ | Incomplete ONVIF support | diff --git a/docs/docs/integrations/mqtt.md b/docs/docs/integrations/mqtt.md index cd6de8651..9b4ad7547 100644 --- a/docs/docs/integrations/mqtt.md +++ b/docs/docs/integrations/mqtt.md @@ -220,3 +220,29 @@ Topic to turn the PTZ autotracker for a camera on and off.
