Event and clip information is managed in a sqlite database at /media/frigate/clips/frigate.db. If that database is deleted, clips will be orphaned and will need to be cleaned up manually. They also won't show up in the Media Browser within HomeAssistant.
If you are storing your clips on a network share (SMB, NFS, etc), you may get a database is locked error message on startup. You can customize the location of the database in the config if necessary.
This may need to be in a custom location if network storage is used for clips.
The input and output parameters need to be adjusted for MJPEG cameras
input_args:
--avoid_negative_ts
- make_zero

--r
-'3'# <---- adjust depending on your desired frame rate from the mjpeg image
--use_wallclock_as_timestamps
-'1'
Note that mjpeg cameras require encoding the video into h264 for clips, recording, and rtmp roles. This will use significantly more CPU than if the cameras supported h264 feeds directly.
The default config will look for a USB Coral device. If you do not have a Coral, you will need to configure a CPU detector. If you have PCI or multiple Coral devices, you need to configure your detector devices in the config file. When using multiple detectors, they run in dedicated processes, but pull from a common queue of requested detections across all cameras.
Tune your object filters to adjust false positives: min_area, max_area, min_score, threshold.
For object filters in your configuration, any single detection below min_score will be ignored as a false positive. threshold is based on the median of the history of scores (padded to 3 values) for a tracked object. Consider the following frames when min_score is set to 0.6 and threshold is set to 0.85:
Frame
Current Score
Score History
Computed Score

0.7
0.0, 0, 0.7
0.0
No

0.55
0.0, 0.7, 0.0

0.875
Yes
5
0.88
0.7, 0.85, 0.95, 0.90, 0.88
0.88
Yes
6
0.95
0.7, 0.85, 0.95, 0.90, 0.88, 0.95
0.89
Yes
In frame 2, the score is below the min_score value, so frigate ignores it and it becomes a 0.0. The computed score is the median of the score history (padding to at least 3 values), and only when that computed score crosses the threshold is the object marked as a true positive. That happens in frame 4 in the example.
For HassOS installations, the default location for the config file is /config/frigate.yml.
For all other installations, the default location for the config file is '/config/config.yml'. This can be overridden with the CONFIG_FILE environment variable. Camera specific ffmpeg parameters are documented here.
It is recommended to start with a minimal configuration and add to it:
Each of your cameras must be configured. The following is the minimum required to register a camera in Frigate. Check the camera configuration page for a complete list of options.

Can be overridden at the camera level. 24/7 recordings can be enabled and are stored at /media/frigate/recordings. The folder structure for the recordings is YYYY-MM/DD/HH/<camera_name>/MM.SS.mp4. These recordings are written directly from your camera stream without re-encoding and are available in HomeAssistant's media browser. Each camera supports a configurable retention policy in the config.
caution
Previous versions of frigate included -vsync drop in input parameters. This is not compatible with FFmpeg's segment feature and must be removed from your input parameters if you have overrides set.
