The NB-IoT-based Smart Locks Solution requires no gateway, facilitating construction and maintenance and reducing maintenance costs.

This solution features good coverage and long standby time. Four AA batteries can lock or unlock a door 8,000 times. This ensures stable lock signal connections.

With the development of NB-IoT, and as privacy protections get stronger, hotel room reservation, check-in, and check-out can all be performed using cloud locks. No reception will be required, making operations a lot less expensive.
