Creating a config file

This guide walks through the steps to build a configuration file for Frigate. It assumes that you already have an environment setup as described in Installation. You should also configure your cameras according to the camera setup guide

Step 1: Configure the MQTT server#

Frigate requires a functioning MQTT server. Start by adding the mqtt section at the top level in your config:

mqtt:
host: <ip of your mqtt server>

If using the Mosquitto Addon in Home Assistant, a username and password is required. For example:

mqtt:
host: <ip of your mqtt server>
user: <username>
password: <password>

Frigate supports many configuration options for mqtt. See the configuration reference for more info.

Step 2: Configure detectors#

By default, Frigate will use a single CPU detector. If you have a USB Coral, you will need to add a detectors section to your config.

mqtt:
host: <ip of your mqtt server>
detectors:
coral:
type: edgetpu
device: usb

More details on available detectors can be found here.

Step 3: Add a minimal camera configuration#

Now let's add the first camera:

mqtt:
host: <ip of your mqtt server>
detectors:
coral:
type: edgetpu
device: usb
cameras:
camera_1: # <------ Name the camera
ffmpeg:
inputs:
- path: rtsp://10.0.10.10:554/rtsp # <----- Update for your camera
roles:
- detect
- rtmp
rtmp:
enabled: False # <-- RTMP should be disabled if your stream is not H264
detect:
width: 1280 # <---- update for your camera's resolution
height: 720 # <---- update for your camera's resolution

Step 4: Start Frigate#

At this point you should be able to start Frigate and see the the video feed in the UI.

If you get a green image from the camera, this means ffmpeg was not able to get the video feed from your camera. Check the logs for error messages from ffmpeg. The default ffmpeg arguments are designed to work with H264 RTSP cameras that support TCP connections. If you do not have H264 cameras, make sure you have disabled RTMP. It is possible to enable it, but you must tell ffmpeg to re-encode the video with customized output args.

FFmpeg arguments for other types of cameras can be found here.

Step 5: Configure hardware acceleration (optional)#

Now that you have a working camera configuration, you want to setup hardware acceleration to minimize the CPU required to decode your video streams. See the hardware acceleration config reference for examples applicable to your hardware.

In order to best evaluate the performance impact of hardware acceleration, it is recommended to temporarily disable detection.

mqtt: ...
detectors: ...
cameras:
camera_1:
ffmpeg: ...
detect:
enabled: False
...

Here is an example configuration with hardware acceleration configured:

mqtt: ...
detectors: ...
cameras:
camera_1:
ffmpeg:
inputs: ...
hwaccel_args: -c:v h264_v4l2m2m
detect: ...

Step 6: Setup motion masks#

Now that you have optimized your configuration for decoding the video stream, you will want to check to see where to implement motion masks. To do this, navigate to the camera in the UI, select "Debug" at the top, and enable "Motion boxes" in the options below the video feed. Watch for areas that continuously trigger unwanted motion to be detected. Common areas to mask include camera timestamps and trees that frequently blow in the wind. The goal is to avoid wasting object detection cycles looking at these areas.

Now that you know where you need to mask, use the "Mask & Zone creator" in the options pane to generate the coordinates needed for your config file. More information about masks can be found here.

caution

Note that motion masks should not be used to mark out areas where you do not want objects to be detected or to reduce false positives. They do not alter the image sent to object detection, so you can still get events and detections in areas with motion masks. These only prevent motion in these areas from initiating object detection.

Your configuration should look similar to this now.

mqtt:
host: mqtt.local
detectors:
coral:
type: edgetpu
device: usb
cameras:
camera_1:
ffmpeg:
inputs:
- path: rtsp://10.0.10.10:554/rtsp
roles:
- detect
- rtmp
detect:
width: 1280
height: 720
motion:
mask:
- 0,461,3,0,1919,0,1919,843,1699,492,1344,458,1346,336,973,317,869,375,866,432

Step 7: Enable recording (optional)#

To enable recording video, add the record role to a stream and enable it in the config.

mqtt: ...
detectors: ...
cameras:
camera_1:
ffmpeg:
inputs:
- path: rtsp://10.0.10.10:554/rtsp
roles:
- detect
- rtmp
- path: rtsp://10.0.10.10:554/high_res_stream # <----- Add high res stream
roles:
- record
detect: ...
record: # <----- Enable recording
enabled: True
motion: ...

If you don't have separate streams for detect and record, you would just add the record role to the list on the first input.

By default, Frigate will retain video of all events for 10 days. The full set of options for recording can be found here.

Step 8: Enable snapshots (optional)#

To enable snapshots of your events, just enable it in the config.

mqtt: ...
detectors: ...
cameras:
camera_1: ...
detect: ...
record: ...
snapshots: # <----- Enable snapshots
enabled: True
motion: ...

By default, Frigate will retain snapshots of all events for 10 days. The full set of options for snapshots can be found here.
