Cameras

Setting Up Camera Inputs#

Up to 4 inputs can be configured for each camera and the role of each input can be mixed and matched based on your needs. This allows you to use a lower resolution stream for object detection, but create clips from a higher resolution stream, or vice versa.

Each role can only be assigned to one input per camera. The options for roles are as follows:

Role	Description
`detect`	Main feed for object detection
`clips`	Clips of events from objects detected in the `detect` feed. docs
`record`	Saves 60 second segments of the video feed. docs
`rtmp`	Broadcast as an RTMP feed for other services to consume. docs

Masks & Zones#

Masks#

Masks are used to ignore initial detection in areas of your camera's field of view.

There are two types of masks available:

Motion masks: Motion masks are used to prevent unwanted types of motion from triggering detection. Try watching the video feed with Motion Boxes enabled to see what may be regularly detected as motion. For example, you want to mask out your timestamp, the sky, rooftops, etc. Keep in mind that this mask only prevents motion from being detected and does not prevent objects from being detected if object detection was started due to motion in unmasked areas. Motion is also used during object tracking to refine the object detection area in the next frame. Over masking will make it more difficult for objects to be tracked. To see this effect, create a mask, and then watch the video feed with Motion Boxes enabled again.
Object filter masks: Object filter masks are used to filter out false positives for a given object type. These should be used to filter any areas where it is not possible for an object of that type to be. The bottom center of the detected object's bounding box is evaluated against the mask. If it is in a masked area, it is assumed to be a false positive. For example, you may want to mask out rooftops, walls, the sky, treetops for people. For cars, masking locations other than the street or your driveway will tell frigate that anything in your yard is a false positive.

To create a poly mask:

Visit the web UI
Click the camera you wish to create a mask for
Click "Mask & Zone creator"
Click "Add" on the type of mask or zone you would like to create
Click on the camera's latest image to create a masked area. The yaml representation will be updated in real-time
When you've finished creating your mask, click "Copy" and paste the contents into your config.yaml file and restart Frigate

Example of a finished row corresponding to the below example image:

motion:
  mask: '0,461,3,0,1919,0,1919,843,1699,492,1344,458,1346,336,973,317,869,375,866,432'

poly

# Optional: camera level motion config
motion:
  # Optional: motion mask
  # NOTE: see docs for more detailed info on creating masks
  mask: 0,900,1080,900,1080,1920,0,1920

Zones#

Zones allow you to define a specific area of the frame and apply additional filters for object types so you can determine whether or not an object is within a particular area. Zones cannot have the same name as a camera. If desired, a single zone can include multiple cameras if you have multiple cameras covering the same area by configuring zones with the same name for each camera.

During testing, draw_zones should be set in the config to draw the zone on the frames so you can adjust as needed. The zone line will increase in thickness when any object enters the zone.

To create a zone, follow the same steps above for a "Motion mask", but use the section of the web UI for creating a zone instead.

# Optional: zones for this camera
zones:
  # Required: name of the zone
  # NOTE: This must be different than any camera names, but can match with another zone on another
  #       camera.
  front_steps:
    # Required: List of x,y coordinates to define the polygon of the zone.
    # NOTE: Coordinates can be generated at https://www.image-map.net/
    coordinates: 545,1077,747,939,788,805
    # Optional: Zone level object filters.
    # NOTE: The global and camera filters are applied upstream.
    filters:
      person:
        min_area: 5000
        max_area: 100000
        threshold: 0.7

Objects#

# Optional: Camera level object filters config.
objects:
  track:
    - person
    - car
  filters:
    person:
      min_area: 5000
      max_area: 100000
      min_score: 0.5
      threshold: 0.7
      # Optional: mask to prevent this object type from being detected in certain areas (default: no mask)
      # Checks based on the bottom center of the bounding box of the object
      mask: 0,0,1000,0,1000,200,0,200

Clips#

Frigate can save video clips without any CPU overhead for encoding by simply copying the stream directly with FFmpeg. It leverages FFmpeg's segment functionality to maintain a cache of video for each camera. The cache files are written to disk at /tmp/cache and do not introduce memory overhead. When an object is being tracked, it will extend the cache to ensure it can assemble a clip when the event ends. Once the event ends, it again uses FFmpeg to assemble a clip by combining the video clips without any encoding by the CPU. Assembled clips are are saved to /media/frigate/clips. Clips are retained according to the retention settings defined on the config for each object type.

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.

clips:
  # Required: enables clips for the camera (default: shown below)
  # This value can be set via MQTT and will be updated in startup based on retained value
  enabled: False
  # Optional: Number of seconds before the event to include in the clips (default: shown below)
  pre_capture: 5
  # Optional: Number of seconds after the event to include in the clips (default: shown below)
  post_capture: 5
  # Optional: Objects to save clips for. (default: all tracked objects)
  objects:
    - person
  # Optional: Camera override for retention settings (default: global values)
  retain:
    # Required: Default retention days (default: shown below)
    default: 10
    # Optional: Per object retention days
    objects:
      person: 15

Snapshots#

Frigate can save a snapshot image to /media/frigate/clips for each event named as <camera>-<id>.jpg.

# Optional: Configuration for the jpg snapshots written to the clips directory for each event
snapshots:
  # Optional: Enable writing jpg snapshot to /media/frigate/clips (default: shown below)
  # This value can be set via MQTT and will be updated in startup based on retained value
  enabled: False
  # Optional: print a timestamp on the snapshots (default: shown below)
  timestamp: False
  # Optional: draw bounding box on the snapshots (default: shown below)
  bounding_box: False
  # Optional: crop the snapshot (default: shown below)
  crop: False
  # Optional: height to resize the snapshot to (default: original size)
  height: 175
  # Optional: Camera override for retention settings (default: global values)
  retain:
    # Required: Default retention days (default: shown below)
    default: 10
    # Optional: Per object retention days
    objects:
      person: 15

24/7 Recordings#

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.

# Optional: 24/7 recording configuration
record:
  # Optional: Enable recording (default: global setting)
  enabled: False
  # Optional: Number of days to retain (default: global setting)
  retain_days: 30

RTMP streams#

Frigate can re-stream your video feed as a RTMP feed for other applications such as HomeAssistant to utilize it at rtmp://<frigate_host>/live/<camera_name>. Port 1935 must be open. This allows you to use a video feed for detection in frigate and HomeAssistant live view at the same time without having to make two separate connections to the camera. The video feed is copied from the original video feed directly to avoid re-encoding. This feed does not include any annotation by Frigate.

Some video feeds are not compatible with RTMP. If you are experiencing issues, check to make sure your camera feed is h264 with AAC audio. If your camera doesn't support a compatible format for RTMP, you can use the ffmpeg args to re-encode it on the fly at the expense of increased CPU utilization.
