    Caution – this model add on sensor (CWPIR) will not work with the RWA-300R base staion. For the RWA-300A base, you need the PIR2-300R add on sensor. (I made this mistake.)

    For the options this is my choice. I bought two base units and three transmitters. I live on five acres and feel safer that i know if a perimeter has been breached. I do have some redundancy because they don’t allays fire off so with layers they catch it, and I’m not surprised by someone coming over. This is common with any PIR sensor no matter how much you pay for it. These PIR sensors are very well protected from climate which is half the battle with this type of sensor. They allow you to know which one was breached with number of tones.

    I have one mounted to my garage. A couple months after installing, I caught a thief breaking into my vehicle (on foot) at 3 a.m., to which I would have otherwise been oblivious. He’s undoubtedly clueless about how I caught him so quickly. For the money, this simple device will help protect your property and family as well as any. If someone’s where they don’t belong, you’re the first to know. Well, technically, the second. Great for a simple alert when you’re away from view of the driveway, and someone pulls in. Great for hiding from approaching Mother-in-laws, too.
