Built for main and internal wooden doors (35–90mm thickness), the GL-400 features a built-in doorbell, voice guidance, and Bluetooth unlocking for smooth and secure operation. The user-friendly mobile app enables you to add or delete users, view access logs, and generate one-time OTPs for guest entry, even remotely.
