Ring Motion Detector (2nd Gen)

Keep an eye on every room in your home – without the cat triggering a false alarm – with the Ring Alarm Motion Detector. Compatible with Amazon Alexa, it alerts you via the Ring app anytime there’s movement inside your home, and the smart sensor can tell the difference between people and pets weighing up to 22kg. Also, the self-adhesive pads and battery operation mean no rewiring is needed, so it can be installed by even the most DIY-phobic. No Wi-Fi or Bluetooth required – Ring’s motion detector uses Z-Wave Wireless Mesh Network technology, so it won’t interfere with your other wireless devices.
