Our 4G door intercom and remote controller deliver a complete access control solution with multiple unlocking and communication options. 

Users can open doors via passwords, SMS, mobile calls with remote key press, or exit button, while visitors can call residents’ phones for remote intercom unlocking. 

Built with a built-in 4G module, the devices operate independently of Wi-Fi or fixed broadband, making them ideal for villas, warehouses, or remote locations.

Administrators can perform advanced management tasks such as unlocking, changing passwords, setting numbers, adjusting volume, or restoring factory settings via SMS, while multi-user support ensures visitor calls are always answered. 

The system intelligently switches to local access when network signals are weak, maintaining stability and security. With a wide voltage and temperature range, and multiple recovery options for admin control, these devices combine flexibility, safety, and convenience, upgrading traditional access control into a fully networked smart intercom system.
