Outdoor camera with night vision - pollen
« on: April 05, 2018, 11:24:55 AM »
I have seen these with my indoor and outdoor cameras at night, particularly the outdoor.   Very interesting.

I would guess more noticeable with a light breeze

I have outdoor security cameras around the house (long story) and they are IR/Night vision.  So  I sometimes see blasts of these,  I also see the heat pattern from the furnace and bugs when they are out and about.   Interesting.

I see stuff flitting by mine, but I figure it's bugs.

Banners, tags, widgets, etc. are why I have Signatures turned off.

I have seen this too but have never heard an explanation for it.

I have seen it on one of my cameras like a flock of something, but the wind is calm, at least that my Davis isn't registering it.  that IR light sure detects things.   I just bought a new air cleaner for the living room . I used to see stuff float at night, it should be interesting now to see how well that stuff stops floating, unless it is supernatural. Then you can find me hiding under the bed with the dust bunnies.

I've seen pollen at night also. I've got a weird looking ribbon bug that trips my cameras all the time and don't know what it is. Any ideas? Correction not all the time only summer months.

I get very similar images if I have IR turned on - thousands per night. The first night I had a camera turned on, I filled a free Dropbox account (2 GB). When I checked, it was mainly fireflies and moths.

I sat out on my porch after dark with a tablet showing a live camera image and a flashlight. When I could see a ribbon on the camera, I tried to get a flashlight on it. I was amazed at how many insects are not visible to the eye but light up under IR.

The length of the ribbon was determined by the "Snapshot duration, Snapshot frame rate and Alarm interval" settings on the camera. The longer duration gave me longer ribbons. The spiral around the ribbon was the wings moving up and down as the insect moved through the frame.

Good to know... The spiral around the ribbon was confusing me, but makes sense now.
Thanks for the report
