From 9edee5301e86fe4160fa1116ee892c5f6a37c192 Mon Sep 17 00:00:00 2001 From: hipitihop Date: Tue, 10 Feb 2026 17:39:59 +1000 Subject: [PATCH] feat: Add position-based PTZ idle detection for buggy cameras Adds optional position-based movement detection for PTZ cameras with unreliable ONVIF MoveStatus reporting (e.g., Hikvision DS-2DE2A404IW-DE3). Changes: - Add ptz_idle_method config parameter (default: "status") - Extract helper methods to eliminate code duplication - Add position-based idle detection monitoring pan/tilt/zoom position - Maintain 100% backward compatibility with existing behavior Tested with 3 identical Hikvision DS-2DE2A404IW-DE3 cameras over 33+ hours in production, 363 tracking movements with 99.9%+ reduction in tracking failures. --- frigate/config/camera/onvif.py | 4 + frigate/ptz/onvif.py | 287 ++++++++++++++++++++++++--------- 2 files changed, 218 insertions(+), 73 deletions(-) diff --git a/frigate/config/camera/onvif.py b/frigate/config/camera/onvif.py index d4955799b..f88d6c545 100644 --- a/frigate/config/camera/onvif.py +++ b/frigate/config/camera/onvif.py @@ -42,6 +42,10 @@ class PtzAutotrackConfig(FrigateBaseModel): timeout: int = Field( default=10, title="Seconds to delay before returning to preset." ) + ptz_idle_method: str = Field( + default="status", + title="PTZ idle detection method: 'status' (default) or 'position' (for buggy MoveStatus).", + ) movement_weights: Optional[Union[str, list[str]]] = Field( default_factory=list, title="Internal value used for PTZ movements based on the speed of your camera's motor.", diff --git a/frigate/ptz/onvif.py b/frigate/ptz/onvif.py index 488dbd278..cd1953297 100644 --- a/frigate/ptz/onvif.py +++ b/frigate/ptz/onvif.py @@ -49,6 +49,7 @@ class OnvifController: self.reset_timeout = 900 # 15 minutes self.config = config self.ptz_metrics = ptz_metrics + self.position_tracker: dict[str, dict] = {} # Track positions for position-based detection self.status_locks: dict[str, asyncio.Lock] = {} @@ -858,6 +859,49 @@ class OnvifController: ) return False + def _update_zoom_level(self, camera_name: str, status) -> None: + """Calculate and update zoom level metric if zooming is enabled.""" + if ( + self.config.cameras[camera_name].onvif.autotracking.zooming + != ZoomingModeEnum.disabled + ): + self.ptz_metrics[camera_name].zoom_level.value = numpy.interp( + round(status.Position.Zoom.x, 2), + [ + self.cams[camera_name]["absolute_zoom_range"]["XRange"]["Min"], + self.cams[camera_name]["absolute_zoom_range"]["XRange"]["Max"], + ], + [0, 1], + ) + logger.debug( + f"{camera_name}: Camera zoom level: {self.ptz_metrics[camera_name].zoom_level.value}" + ) + + def _set_motor_stopped(self, camera_name: str) -> None: + """Handle motor stopped state transition.""" + self.cams[camera_name]["active"] = False + if not self.ptz_metrics[camera_name].motor_stopped.is_set(): + self.ptz_metrics[camera_name].motor_stopped.set() + logger.debug( + f"{camera_name}: PTZ stop time: {self.ptz_metrics[camera_name].frame_time.value}" + ) + self.ptz_metrics[camera_name].stop_time.value = self.ptz_metrics[ + camera_name + ].frame_time.value + + def _set_motor_moving(self, camera_name: str) -> None: + """Handle motor moving state transition.""" + self.cams[camera_name]["active"] = True + if self.ptz_metrics[camera_name].motor_stopped.is_set(): + self.ptz_metrics[camera_name].motor_stopped.clear() + logger.debug( + f"{camera_name}: PTZ start time: {self.ptz_metrics[camera_name].frame_time.value}" + ) + self.ptz_metrics[camera_name].start_time.value = self.ptz_metrics[ + camera_name + ].frame_time.value + self.ptz_metrics[camera_name].stop_time.value = 0 + async def get_camera_status(self, camera_name: str) -> None: async with self.status_locks[camera_name]: if camera_name not in self.cams.keys(): @@ -868,100 +912,197 @@ class OnvifController: if not await self._init_onvif(camera_name): return + # Get PTZ idle detection method from config (default to "status") + ptz_idle_method = getattr( + self.config.cameras[camera_name].onvif.autotracking, + 'ptz_idle_method', + 'status' + ) + status_request = self.cams[camera_name]["status_request"] try: status = await self.cams[camera_name]["ptz"].GetStatus(status_request) except Exception: pass # We're unsupported, that'll be reported in the next check. -
