Because of some false ‘door opening’ alerts, I was thinking about relocating my Garadget’s laser beam to the less-bright, lower region of my garage door. However, thinking about your recommendation to point the laser toward the garage door’s top panel, I decided that point the laser beam below the top panel would would almost never be a good idea, for these reasons:
- When the Garadget device is located on the (bottom of the) door opener, directing the beam toward the top panel of the door usually results in a fairly level beam — thereby, more intense — reflection back from the reflector tape;
- A tall enough person walking in the vicinity of a lower-pointing laser beam might inadvertently move his/her head through the laser beam, thus risking retinal damage from looking directly at the laser beam.
- A person who accidentally interrupts a lower-pointing laser beam would thereby trigger an erroneous ‘door opening’ alert each time.
So for these primary reasons I wholeheartedly endorse your recommendation to point the laser beam at the center of the top panel. However, I am still left with a challenging problem to resolve: I have a type of garage door in which the panel immediately below the top panel is made up of a row of windows. I think the bright, albeit indirect, midday light passing through those garage door windows is somehow diluting the Garadget’s ability to ‘see’ the reflected laser light, which I believe is why my device gives a number of false ‘door opening’ alerts in the middle of bright, sunny days.
Question: For garage doors like mine, viz., with a row of windows comprising the panel immediately below the top panel, Could I resolve those false ‘door opening’ alerts simply by reducing the amount of light that passes through the window(s) nearest my laser target?
