Using NestMTX as a feed source for Frigate
Frigate is a complete and local NVR designed for Home Assistant with AI object detection. Uses OpenCV and Tensorflow to perform realtime object detection locally for IP cameras.
NestMTX was designed primarily with integration with Frigate in mind. Specifially, it ensures that feeds are output using H.254 encoded video tracks, and AAC encoded audio tracks. And while NestMTX is compatible with the majority of the protocols which Frigate is able to work with, it is recommended to use the RTSP protocol.
Note
This tutorial assumes that you have NestMTX running at the hostname my.nestmtx.local
, has enabled RTSP feeds, and has been setup to listen for RTSP connections on port 8554
.
Important Note
This tutorial assumes that you are running Frigate version 0.14.x
. While this tutorial may also work for previous versions, we do not have confirmation at this time of it working with previous versions.
Basic Camera Configuration
The following example is the most basic camera configuration for integrating a NestMTX feed into Frigate:
My_NestMtx_Camera:
enabled: true
ffmpeg:
input_args: preset-rtsp-restream
inputs:
- path: rtsp://my.nestmtx.local:8554/my_nestmtx_camera
roles:
- detect
- record
- audio # for audio detection
Note
The preset-rtsp-restream
ffmpeg preset was chosen due to its overall stability and compatibility.
Setting Resolution
NestMTX is able to detect the camera stream resolution from the camera's API properties. Because this information is known in advance you can configure Frigate to use this resolution by default instead of having it try to determine the correct resolution. This is done by configuring the detect
property of the camera. For example:
My_NestMtx_Camera:
enabled: true
ffmpeg:
input_args: preset-rtsp-restream
inputs:
- path: rtsp://my.nestmtx.local:8554/my_nestmtx_camera
roles:
- detect
- record
- audio # for audio detection
detect:
width: 640
height: 480
Setting up Go2RTC for Live View
In order to allow the Frigate UI to use a higher quality live view, you can also set your camera feed under the go2rtc
> streams
configuration. For example:
go2rtc:
streams:
My_NestMtx_Camera:
- rtsp://my.nestmtx.local:8554/my_nestmtx_camera
