    Tips for mounting cameras behind glass?

    But if it can reach out to 45 metres, presumably it is emitting more IR than a spotlight that is designed to reach only 10 metres i.e. it's 'brighter'. To me, that means that there will be more IR to pass through the glass and be picked up by the internal camera. Or doesn't it work that way?

    Tips for mounting cameras behind glass?

    I have been monitoring my driveway with an internal IP camera behind a double-glazed window. I have disabled the IR leds, so as to avoid any window glare, and have illuminated my driveway with an external IR spotlight with a range of 10 metres - which is the length of the driveway. Whilst this is fine during the day, the night image is extremely poor, presumably because a lot of the IR light is being blocked by the double-glazing. In addition, the driveway is 45 degrees to the house so I cannot get the camera right up to the window, although it is in a spare room that is unlit. If I were to replace the 10m spotlight with one that has a range of 45 metres, would I see any significant improvement in the image? At present, I can barely make out the shape of the car on the driveway. With the window open, the image is much better so it does seem that the window blocks most of the IR light. Clearly, the best option would be to have an external camera, but I was hoping to have the camera inside so as not to annoy neighbours etc. Thanks for any advice.
