Wireless door and window sensors

Know whether doors and windows are open or closed, in real time

Our wireless door and window sensors automatically detect open doors or windows around your building, including doors on cupboards, cabinets and fridges. The small, solar-powered contact sensors use ultra-low-power wireless technology, making them easy to install and very low maintenance. Optional battery back-up version available for low-light environments


Get accurate, reliable door and window status updates

The sensor simply sticks to the frame and sends an instant update if the open/close status changes.


Solar-powered with battery back-up for easy install

The sensors use ambient room light – natural or lighting – with a battery back-up, making them super easy to install and very low maintenance.


Access real-time data locally or in the cloud

Open/Close data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi — using Pressac’s smart gateway.


  • Use magnetic fields to detect open/close status. Reports open/close changes in real time and status updates every  15 minutes
  • Small, discreet sensors simply stick to a door/window frame
  • Solar-powered using ambient room light – optimally angled to absorb light – with a battery back-up for periodic low-light conditions. Batteries typically last up to 10 years
  • Transmit data wirelessly and securely – using AES-128 encryption – via EnOcean wireless protocol, which uses internationally approved, licence-free ISM bands
    • 868 MHz for Europe (RED)
    • 902 MHz for North America (FCC) and Canada (IC)
    • 928 MHz for Japan (ARIB specification)
  • EnOcean Equipment Profile (EEP): D5-00-01
  • No recurring fees. Access the data through your chosen platform, without any additional costs from Pressac
  • Manufactured in the UK to high-quality and high-safety specifications, they are subject to rigorous testing procedures
  • Dimensions:
    • Sensor: 76.5 x 28 x 17.5 mm (approx)
    • Magnet: 62 x 12 x 13 mm (approx)
