Alister Posted November 7, 2007 Author Share Posted November 7, 2007 are you pointing the camera through the glass of the window or using ambient light provided by it?you will likely get ir bouncing back into the lens regs alan Both the camera, either with built-in I/R or stand-alone I/R, will be positioned on a window cill. The light for the camera will be provided only by the covert I/R illuminator. Another aspect of the question is - If the camera (and I/R) are positioned hard up against the window glass will reflection still occur? Link to comment Share on other sites More sharing options...

Another aspect of the question is - If the camera (and I/R) are positioned hard up against the window glass will reflection still occur? if you use the type that have the led's as a ring around the lens they will 'halo' off the glass when the photo cell decides to switch on, end's up looking like a british gas advert to help void this you would be better off imo to use a separate lamp and camera, but the cheaper one's still give a visible red glow and you might still get reflections if the camera is away from the glass,, which it most likely will be to get the required view. depends on the job obviously, why not use a v/r dome they are not that big, but if you must hide it you could use a small bullet camera behind a mesh grill or air brick installed for just this purpose, then use an auto flood for illumination as imo better to try to try and deter prior to than detect after the event regs alan If you think education is difficult, try being stupid!!!!
