  • The Aleph America AL-40 PIR Intrusion Detector provides high quality security at an outstanding value. PIR devices can detect a person moving into or through a detection zone with high reliability. The slightest positive or negative thermal radiation change in contrast to a background triggers the sensor element. There is no interference between neighboring units due to the passive nature of the detection principle. The use of differential or dual-channel sensor technology and advanced digital signal processing reduce false alarms caused by turbulence. Similarly, precision optics accurately define the field of view, allowing consistent and long-range coverage. The PIR Intrusion Detector features Qualified Motion Analysis (QMA), digital operating system, dual slope temperature compensation and rock-solid RFI immunity. The detector also features multi-function LED with ambient temperature detection and self dimming LED. Optional 100 lb Animal Immunity lens included.

    Smarthome does not accept defective returns for this product. You will need to contact the Manufacturer (or Supplier) directly for all warranty issues.

    Review of 79200

    An ADT second party company installed these in our home when we ordered an alarm system. They charge a lot more for them too, $100. We had two of these installed and they were needed to cover out to about 30 feet. They will do this but only on target walking upright at normal speed. My wife and I both repeatedly crawled right past these at about 20 feet and at a moderate speed. My wife was able to slowly crawl right up to it from over 30 feet away until she was below it. At about 20 feet I walked right past it by moving slowly. Just understand the limitations of this sensor. It wont work well on slow moving targets, especially if they are crawling. A criminal may decide to just see how far he can get and then run if it detects him. You never know and we didnt want to take the chance.
