Takex America Inc.(Pulnix) PA-7012E Passive Infrared Motion Sensor

We're going to talk about peripherals, in particular motion detectors and glass break detectors. Sometimes I hear you guys explain how motion detectors work and I cringe a little bit, so I want to make sure that we're on the same page as far as how that happens. So I don't have a fancy thing like Frank did, and I didn't put my name on it so I can disavow it if I need to, but-- So light, heat, and IR energy all go together. They're not all the same thing, but if you have one, you'll usually have at least one of the other. And the only reason I say most likely have at least one of the other is because LED lights don't give up a lot of heat. But that's what makes it easy to think that when you're talking about passive imprint motion detectors detecting a person's body heat, that that's what's happening. But in reality, that's not what happens. It's detecting infrared energy. Infrared energ
