Why Buyers Choose This Model
What This Helps You Avoid
A single unsecured entry point can leave your entire property vulnerable. Without immediate notification when a door or window is opened, valuable time can be lost before anyone realizes something is wrong.
DoorProtect Jeweller helps eliminate that uncertainty by providing instant opening detection and secure wireless communication to your Ajax Hub. Instead of worrying whether a window has been left vulnerable or a restricted area has been accessed, you'll know exactly when an opening event occurs.
The long battery life also helps you avoid frequent maintenance visits, while encrypted communication reduces the risk of interference or unauthorized access. The result is greater confidence, fewer security gaps, and dependable protection every day.
