Sometimes "no recordings found for this time" but not always

[bonjour81]

Hello,

Yesterday evening I had some events with "no recordings found for this time" : I can see the event in review tab, I have snapshots, I even have working video preview if I hover my mouse on the preview picture. but I cannot open the video footage.

2 days ago I setup frigate+ custom model and modified my config, so maybe it has something to do with it that if I didn't understood correctly some configuration.

Today I had a few captured events, with video, no more problem.

Here is an extract of my config:

Note: while it's a wifi camera, it's usually pretty stable and I didn't notice error message in logs (unless I missed it)

In order to setup my frigate+ model, I just follow like explained here : https://docs.frigate.video/plus/first_model
But I'm not fully sure of the need of step 4 here and what does it do vs my current config with objects/tracks/filters inside the camera settings.
Is this section at root of config mandatory ?

Note: I have not very high threshold on purpose (you can 0.65 or 0.7) to have more detection than expected, in order to evaluate where I am with new model and tune it later for each camera.

As I'm not sure about the purpose of object/filter at root of config file (step4), I was wondering : can it be that frigate trigger an event starting from 0.65 that I set here but filters recording below 0.7 as I set in camera settings ?
Say Frigate detect something at level 0.68...could it pass the 0.65 and trigger an event but won't record because it's below 0.7 ?

[NickM-27]

are you seeing this for only detections, or alerts too?

[bonjour81]

I think it was in alerts only, but I cannot find them again...can it be some automatic cleanup?

[bonjour81]

I mean gone from review section (even with "show reviewed" enabled),but still have then in snapshots.

[NickM-27]

It could be, the next version makes this simpler
