[Support]: Person count = 1 when night mode activated on camera

[krustophenia]

Describe the problem you are having

When the night mode starts, the camera entity person_count increases to 1 for a random period of time (it can be a couple of hours, 6...) and even checking on debug mode there's no person detected anywhere.

Any other information that may be helpful

When setting the switch from day to night mode automatically the error popped on one of the cameras. Switching it to schedule fixed it. The other camera that showed this same behaviour had the same configuration (auto switch) (profile management > Day/night). Is maybe an issue with the way the cameras switch the modes?

[NickM-27]

night mode itself won't affect this, most likely it saw a person. What did you do to check the debug live view? (what switches are enabled)

more info is needed to help with this, but I'd say this is most likely just a false positive

[krustophenia]

There you can see one of the cameras on debug when that was happening and the two entities (the cuts on the graph are because I tried to restart HA, frigate and the cameras). Trust me, nobody was there for that amount of time.

[NickM-27]

Your debug screenshot is not helpful in terms of knowing if frigate sees a person or not. That screen is just for editing the zones and masks.

Trust me, nobody was there for that amount of time.

Sure, but it could easily be a false positive where frigate thinks it sees a person. I still think this is the case as nothing has been shown to show otherwise.

[krustophenia]

I've done a test and it was detecting a person where there was a chair on the patio. I removed the chair and the person count was still 1. Is there a way to make it update faster? Is it still a false positive?

[krustophenia]

Just found out that if I restart home assisstant, those entities go back to 0... Any idea?

It updates immediately so if it shows 1 then it still sees something as a person

Just found out that if I restart home assisstant, those entities go back to 0... Any idea?

Right... because restarting it makes it lose current detections and then it restarts it doesn't see the false positive anymore

[renorg]

Hi, i would like to come back on this problem, as i got exactly the same. Like krustophenia, this happens only in night mode. I'm sure there is no false positive detection because frigate makes records for all person detection, and in this case, there's no record. I would like to use this detection to switch on a light, but in this case, the light is always on 😅 Don't you have an idea about this ghost presence? 😁 Thanks a lot
