jray3369 0 Posted July 30, 2011 i have a problem with my coms cams, when i view thru our energy efficent windows the picture is great but as soon as i put them out side or just open the window the color is washed out and looks b/w. Any solution, thought about window tint ont he lens as it may be a UV thing? Cheap cams by the way but do able for my situation. thanks Share this post Link to post Share on other sites
Soundy 1 Posted July 30, 2011 My guess would be that the window has a UV-blocking coating that's causing this effect. It's probably acting similar to a "haze filter" for a still camera. Share this post Link to post Share on other sites
Gator 0 Posted August 13, 2011 It's the infrared coating that causes this difference. Energy efficient windows are coated to block IR. The camera is sensitive to IR but the IR response shows as different colors. If you can put an IR filter in front of the camera, the colors will improve.

Soundy 1 Posted August 13, 2011 Ah, Gator, good catch! You're right, of course: cheap IR color cameras don't have the standard IR cut filter that color cameras normally need for proper color reproduction, so an IR-blocking window is just like adding that filter in.

It's probably acting similar to a "" for a still camera. it is the tint that is saving your butt here... the uv film will bring the brightness and glare down...
