I would like to put Outdoor IR cameras inside metal housing but was told the IR Leds will reflect off the glass in the housing. The cameras are designed to mount stand alone. Is there anyway to set these up without removing the glass in the housings? They are being used in a very crime ridden area and the highest they can be mounted under eve is around 14 feet off the ground. Thank you Dave
The problem is that some light will be reflected back and the camera will just see the inside of the glass lens. Just like standing inside your house at night and looking out. You just see a reflection.
HOWEVER there are some package cameras built that eliminate this problem by having a rubber boot/gasket around that lens of the camera that rests flat against the inside of the glass.
I have used domes built this way. With domes its difficult to get everything adjusted and positioned correctly, but it can be done. Just takes times. There are also some complete packaged cameras and illuminators with a fixed focus that handle this nicely.
I originally ran across this problem many years ago when trying to video tape out a window. A piece of cardboard around the lens to block the reflection did the trick.
Thank you for the suggestion. These cameras have a gasket around the lens preventing surounding IR lights around it from reflecting back into it. I'll experiment with a gasket between the housing glass and the camera to see if this works. Dave
The camera worked in the outdoor enclosures after installing a 1/4" long round plasic cylinder wrapped with black tape around the lens preventing IR reflections. Lens cleaning in the future may prove to be difficult. Dave
