Local realtime person detection for RTSP cameras

From the user experience - how many TPUs are needed to run eight full HD cams? 4k cams?

3397

Any ideas why the CPU latency grows over time? Had a fresh install of the forked addon (running on an old c2d processor machine). One camera attached with 640*480@5fps resolution. At first inference speed showed up at 10ms.
After 8 hours of running it’s behind 800ms. Looking at htop - cpu utilisation is below 2%

Thanks! I will give it a try when I get home from work. That sounds similar to what I tried to achieve, but I failed extracting the relevant content from the mqtt-feed. I might come back later with further questions :wink:.

You did not specify if you are using a coral and what is your CPU. Read the docs again for Frigate for recommendations and how to run

Without Coral.
Config is as follows

detectors:
  cpu1:
    type: cpu
  cpu2:
    type: cpu
3401 
detectors:
  coral:
    type: cpu
    device: usb
    num_threads: 2

This is my setup for i5.

3402

Getting confused by Hass addons.

Witch Frigate addon is the latest?
NVR Beta or NVR version?

3403

Looking at the tensorflow docs - what is the point of putting in device:usb?

3404

This is expected than, your CPU is not able to handle the 10ms inference time, 800ms is expected.

3405

I concluded that the ‘NVR Beta’ was older/obsolete.

3406

From the docs:

format=android, what does this do and is there an equivalent for iOS?

Thanks

3407

Thanks. Strange this is version numbers.
NVR says 1.6 and NVR Beta says 1.8 …

Will try to install NVR and see what happens.

3408

Beta is always newest version :smiley_cat:

3409

In this case it’s not . :slight_smile:
Just saw this …

I got my coral from Raspberry store it seems they still have them in stock. They ship to european countries.

Currently no active beta version (it mean that beta is outdated):

3412

i ahve to admit that i have some difficulties followig this app. Configurations are not the same for beta and stable releases and version numbers are weird BUT the app is MORE THAN AWESOM! :heart_eyes: Now I just need that @blakeblackshear throws an eye on this as there might be a problem with latest supervisor version. Config cannot be saved as described above in my post :frowning:

this sounds like this addon is no longer working without coral if I am not wrong.:

  • Fallback to CPU if the EdgeTPU is not detected has been disabled. It will now keep trying to detect your EdgeTPU.

You should use cpu mode in config in that case.

It’s normal that configuration may changed between major versions.

3414

all right I get this :slight_smile: thanks @arkoko I am absolutely NOT complaining :slight_smile: I use coral. Now I just wait for a fix to save config.I manually added my config in the frigate container but this does not work at all as i need ingress. Does someone else use latest Suervisor here and has problems with this addon?

I’ve not using HA and Supervisor beta versions, but if I understood correctly today will be expected scheduled release 2021.2.1. Then we’ll see :slight_smile:
