What is a 4G Video Doorbell?
A 4G video doorbell is an intelligent security device that transmits data based on 4G mobile networks. Integrating a camera, microphone, speaker, motion detection sensor, and doorbell button, it operates by inserting a SIM card (or with a built-in eSIM) directly, eliminating the need for Wi-Fi connection. Compared to traditional Wi-Fi-dependent video doorbells, its most prominent feature is breaking free from geographical and network environment constraints.
Core Working Principle
1.Trigger: The device is activated when someone presses the doorbell button or the sensor detects movement near the door.
2.Recording and Uploading: The camera starts recording video (or taking snapshots) and transmits the video data to the cloud server via the built-in 4G module and mobile network.
3.**Notification and Viewing: The user's mobile APP immediately receives a call or alarm notification. By clicking the notification, the user can remotely view the situation at the door in real time and conduct two-way voice communication with visitors through 4G/5G or Wi-Fi networks.
4.**Storage**: Videos are typically stored in the cloud (requiring a subscribed cloud service) or on a memory card built into the device.
