I have a motion sensor that was here when we bought the place. The previous owner had some company doing some monitoring for them and that’s who installed it.
Anyways, when I take off the back cover, it says “Secure Wireless Inc” and the model number is SW-PIR-SW.
Anyone have any idea on how to pair this with ST?
Thank you.
It’s unlikely that it will pair with smartthings. Smartthings hubs have a Z wave radio and a Zigbee radio, but most security systems use other frequencies. 
Is there an FCC license number on it? If it’s a battery operated device, the label might be inside the battery compartment. The FCC license will tell you what frequency it uses.
FCC ID is QNP-EVPIR433
Ok, that operates on 433 MHz, which is a radio that the smartthings hub does not have, so no integration is possible. 
Thanks.
Do you think it’s a safe bet to say the open/close sensors are the same? The biggest chip on the board says 13.560zOZ
The chances of it being anything but… Is ridiculously small… Especially if thats a security system board more than two years old.
So new motion detector and sensors it is! Thanks everyone!
Or you do what I did, dump the security board for one Icould integrate into ST. 
but you are correct that tose sensors won’t directly integrate. HOW you solve that problem is your choice.
