The Complete Sentry Kit

All four techSafe devices in one box. The Room Sentry 130 braces and alarms the main door. The door jammer adds a second physical layer at floor level. The wireless door and window alarm covers every other way in. And the pocket SOS alarm rides on your keys for the walk back to a locked door.

Bought separately they come to $165.96. The kit covers every layer of the night for $99.99.

Every device works without apps, wifi or pairing, and the 60-night guarantee covers the whole box.
