So, I purchased an older MacBook from work - that has been my own for 4 year, and got hands on a older MacBook and it seemed fit according to the Recommended Hardware.

Also, I am equipped with 4 Reolink Cams and a Coral stick, but I have not used any reolink Reolink specifics from Camera Specific Configuration.

And of cause, I have a Home Assistant installation running.

Preparing the MacBook Firmware/T2

I had some problems with removing the activation lock and even do an Internet recovery (that just failed with 1008F Error). but when the MACOS finally was cleanly installed, make sure to enable USB Boot, as this:

Installing Ubuntu

I had a lot of trouble actually getting the danm thing to boot, but on a stick with Ubuntu 22.04 (used Balena Etcher), it finally did.

...

I had a lot of problemes getting to use the disk, several times the installer just crashed and restarted, and or stopped with "Installing grub on taget device failed"

But I finally got the installer to r emove remove all partitions and install, with the "Use custom partitions" option - make sure to whipe and erase all partitions on the disk. 

After the install the "df -h" command told me that only 100 GB of the disk was used - I have no clue why the installer sets it up this way..

But the fix was eady easy - first examine the LVM:

Now, we can see 0 "Free PE :/ Size 0 / 0"

Ubuntu is installed and the complete SSD Disk usedis now utilized.

Docker install

Lets install docker.io:

Kodeblok
apt install docker.io


Frigate NVR Install

Find information on Frigate here

Tip

First, I generally put all docker stuff in /opt 

Creating the needed Directory and the config file:

opt - and I dont use docker-compose very much. Maybee one day...


Creating the needed Directory and the config file:

Kodeblokcode
mkdir /opt/frigate
vi /opt/frigate/config

...

The config file can be huge and there are plenty of options, here is my current:

Tip

In short, the file sets up three cams (Reolink) - using:4 cams - using:

  • go2rtc as "proxy" - this made a huge difference and improvement (Istarted using RTSP streams directly into frigate, and the recorded videos lagged and was sometimes broken). See https://docs.frigate.video/guides/configuring_go2rtc
  • The Lowres RTSP stream (sub) for the Detect role as generally recommended, as frigate only uses a 300x300 pixel image for object detection. See https://docs.frigate.video/frigate/camera_setup
  • The highres RTSP stream (main) for the Recording Role (sub) as generally recommended.
  • The highres RTSP stream for the Recording Role (Main) as generally recommended.

  • input_args: preset-rtsp-restream as recommedded for Reolink (see https://docs.frigate.video/configuration/camera_specific)

  • Recording event Recording on object detection
  • Take snapshots on event
  • The tracking of persons and cars
  • The use of a Coral stick for Object processing .- instead of the CPU

Reference to the configuration file is here.

Coral Stick on Linux

I had some problems getting the Coral stick to work (the Frigate docker image has all needed for it), but it did not show up as an Device on the MacBook:
