Motion Detector Bug Guards
This is a bug guard. You sometimes see them talk about bug guards, that it's a feature that cuts down on false alarms. Bugs love to get into motion detectors because they're warm, especially when the seasons change, like in the fall. They like to get in there and get warm. And if a bug gets in, he's going to probably set it off. Because if you think about it, like my glasses. Motions are a lot like people. If they don't have a lens, they can't see anything. If I don't have my glasses, I can't see anything. If I look at a fly on that wall over there, it's going to look tiny to me here. If that same fly is walking across the lens of my glasses, it's going to look huge. And it's the same for a motion detector. That's why we say bugs crawling across the lens can trip it, bugs getting inside on the lens can trip it. So the bug guard is actually built into the lens on this one, which is interesting, but you can take it off. So here's the lens. You have to be able to take it off because you can mask this lens. So pass that around. You can see what the swirly parts on the inside, this is where all those zones come from. So infrared energy passes through this lens. It gets kind of divided up into these zones. And it kind of takes a picture of the room, if you will, when that happens. And then if somebody walks in, they're going to change the infrared energy that it sees coming into one or more of those zones, and that's what's going to cause it to trip. You can actually mask these. So there's different ways that you can determine where the motion can see. This is the masking thing for that particular motion. It's got a grid layout that shows you all the different little zones that we talked about, short range, long range, and intermediate. And you can say, oh, I need to mask off this zone. You can take this sticky stuff and stick on there and it'll mask you. If it's masked, it can't see in that area. So let's say you had a pet and you had that motion, you probably want to mask off the lower zone. Right. Now, some of these, if they're pet immune, they just don't have a lower zone. So some of them don't do look down, some of them do. Some of them have an option. This one, actually, has an option right here. If you don't want look down, you pull this little tab out. If you do want it, you push it in. So you [INAUDIBLE]? Right, sometimes. Different environments have different requirements. So you might have an area where you have an environmental factor of it that happens certain times of the year, certain times of the day where maybe the sun comes in a window and heats up a particular area. That can sometimes cause a [INAUDIBLE].. You might be able to mask and make that not happen. You may be looking at a doorway. You want to cover this room, but not that room with this motion. You could mask for that.
