This is my go-to wireless PIR motion sensor when using 2Gig or Honeywell alarm systems. It has a good detection range, good battery life and a high-quality detector. It lacks pet immunity as my cats run it quite often, so it's better suited for non-pet applications, self-monitoring systems, or in conjunction with surveillance cameras. Yes, this particular step is fairly simple but effective and I have installed many of them with confidence.
