I think we're talking about two different type of devices. What I'm familiar with detects motion. Rectangular black colored light box with grey sensor at the bottom. Unit has a long, thin bulb that gets extremely hot when on. I forget the bulb type name? They do get set off by any motion within their range whether warm bodied or foliage.chopsticks wrote:Pete, I don't think bushes and trees will set them off as they use body heat (passive infra-red detectors).prcscct wrote:My problem which I think is common to many is too many bushes and trees. I don't have one spot, except straight down the driveway, where one wouldn't be set of continuously when the wind blows. As all this stuff grows what is a good spot now may not be in a few months.Super Joe wrote:Something no-one seems to mention or never seem install in HH is motion sensor flood lights, is it a gecko problem ?

Indeed there may be the kind you're referencing and I'd like to know more about them as would solve my problem. Pete
