Record to much during night time.

Post by dalbjerg »

Hi

I have a video that recode this area: http://kennethdalbjerg.dk/files/downloa ... 013343.png

Duing daytime, there are not many videos.
But doing the night it will record at lot of time 4-5 times pr. hour.
For duing around 10 minutes. so almost everytime.
Screenshot from one of the video: http://kennethdalbjerg.dk/files/downloa ... 013156.png

The camera is unifi G3 camara.

The video is set to record in Modect, and have this zone configure: http://kennethdalbjerg.dk/files/downloa ... 0Zones.png

Alarm Check Method is set to Blobs
min/max pixel: 35
filter width/hight 9 / 9
min/max alarmed area: 2800
min/max filtered area: 1000
min/max blob area: 9000
min/max blobs: 1

But I can't figure out what this number mean, and how to set it correct up.
Can anyone help me, why the camera duing the night is recording almost everytime?

Is the movement camera noise? I had to change the color change values to stop the noise movement.

My cameras have low light noise, a pixel shifts from one color to another. This frequently happens in groups and causes a motion event to be detected.
