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.

Please note, to use the Ring Alarm Motion Detector you’ll need to download the free Ring app, which is compatible with all iOS and Android devices. You’ll also need the Ring Alarm Security Kit (sold separately).
