Rain causes steaking on video

Hello All

I am using Geovision Cameras and they see very sensitive in the rain. Does any one have any ideas what settings I would have to adjust on the camera to stop this? My Amcrest Cameras do no seem to have this issue.
Thanks!

That is infrared bounce off rain close to the camera.

Put the camera in color or use external IR instead of camera IR or provide longer cover distance over the cameras by moving cameras back.

Ok thanks for the quick responds. Do you know if there are 3rd party "visor" to put on a turret camera? some thing to maybe glue on. Like the camera below has a "visor"

Thanks

Many here will make one out of metal or pvc pipe to extend.

No one has made a heat shield out of a beer can before?

I've gone to using external IR on all my cameras because of this. It's even worse with snow. Why it's different with the Amcrest cameras is a head-scratcher for me.

I've made a few sunshades out of cans. Some soup cans are the exact correct size for some of the Dahua turrets.

Might just be the location/view of the Amcrests. Some of my identical cams look different as far as that goes depending where they are. You could try changing shutter settings but that's going to change things overall beyond just rain.

Doubt that any shield like that will help much. It's not rain that's hitting or that close to the lens. It's rain that's farther away than that but still close enough to be highlighted by the IR.

In your image note that the only cam with rain streaks are the ones in IR...the color image has none. If this issue is important enough to you to resolve, then read further.

I'd say if there's not enough ambient light to force cams into color mode then place outboard IR emitters away from the face of the cam and in such a way as to target the ground that the cam is pointed at; the IR will still be seen by the cam if it's strong enough and oriented properly. Under the cam would be a good place to start with the location of the outboard IR emitters.

The IR emitters should have their own built-in photoelectric cell that will turn the unit on a dusk, off at dawn. Most will also require 12VDC to operate.

You'd then disable the cam's IR so it won't be hitting the rain which is just a few inches away from the cam's face, causing the issue.
