Wireless door and window sensors

Remotely monitor doors and windows are open or closed

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.

If you’re looking to order sensors for a project or have regular requirements for sensors, please contact our friendly team to discuss pricing options and availability.

We offer volume discounts and bespoke branding.
