OT Internet Camera Problem

Fascinating situation I have. A security camera keeps flashing its video in
monochrome, then grainy color, and maybe off, flashing very rapidly.
Replacing the camera and the power supply did no good. And this happens
only between about 3pm and 4:30. Otherwise both old and new cameras and old
and new power supplies work flawlessly during other time periods.

The power supply runs into a UPS power supply which also feeds the camera
DVR and monitor, which aren't showing any problems. The camera is above a
washing machine and adjacent to an ice machine, but the staff does wash
whenever needed, not at set times of the day.

It's not causing any problem except that the flashing means that the
movement sensing is always showing movement, so we get 17 days of video
rather than 19.

I'm just curious as to what could be causing this. It hadn't always been
this way, and as I said, it only seems to happen between about 3 and 4:30pm.

Odd, no?

It's a common bug where night mode turns on and off repeatedly at
morning and dusk. Try activating it at lower light levels when there
are no longer any moving shadows.

Yes, my security cameras cycle through like in the AM as the sun rises. It may or may not trigger an alarm.

I'm watching security cams for home getting cheaper. I have my two camera out of box system and another one 1080p cheap webcam keeping a 2 fps watch over the street in front. I'm thinking of replacing that with an inexpensive IP camera that can also be run on Ethernet or just to a micro SD card to capture night events.

We've had some burglars busted recently in the East Bay from videos that folks caught of them outside their home.

Hmmm...interesting idea and one I hadn't thought of. However, there is no
varying light level in the storage room. The lights are either all on or
all off, and this happens only during the afternoon...whoa! I think you're
onto something. There's a side door that is open during the afternoons.
I'm going to check it with that door open and closed. Excellent
observation!

Heat maybe? Also, in regard to cameras pointed outdoors, this community recently replaced the mercury vapor street lights with LEDs which may present an new problem as far as night viewing goes.

This is an indoor camera in a storage room. A side door is opened for
deliveries in the afternoon, but I haven't had a chance to check that out as
a culprit. Heat, now that's an interesting issue. I'll check on that.
