4-Wire 7 in Tuya 1080P WiFi Smart Video DoorPhone Intercom - Remote

In this review of the 4-Wire TMEZON 7 in Tuya 1080P WiFi Smart Video DoorPhone Intercom System, the bottom line is straightforward: it is a practical, feature-rich intercom for homeowners who want smartphone access and a clear 7 in indoor monitor. The setup is aimed at users comfortable with wiring or hiring a technician, and the biggest reason to buy is the combination of a 7 in touch screen monitor, 1080P outdoor camera with night vision, and TuyaSmart app control that lets you see and remotely unlock the door from anywhere.

Key Features

• Remote App Notifications: When a visitor presses the doorbell the TuyaSmart app notifies the phone so you can see, hear and talk to callers and remotely unlock from anywhere.
• 7 in Touch Screen Monitor: The slim 7 in TFT monitor offers touch key operation and hands-free indoor use for clear local monitoring and control.
• 1080P Doorbell Camera: The doorbell unit records 1080P video with a 125 degree wide angle, infrared night vision and a waterproof, anti-vandal enclosure for outdoor reliability.
• Automatic Snapshot and Recording: The system takes snapshots or records video to a Micro SD card when the bell is pressed or motion is detected, allowing later review on the app or monitor.
• Multi-Unit Intercom: You can connect up to six monitors, two doorbells and two CCTV cameras for flexible multi-room communication and call forwarding between monitors.
• Wired 4-Wire Connectivity: The 4-wire design supports runs up to 100 meters between the bell panel and the last monitor and integrates with 12V electronic locks for remote unlocking.

Who It's For

This system suits homeowners in apartments, villas or small commercial sites who want an integrated video doorbell with a local indoor monitor and smartphone access via TuyaSmart. It is especially useful where multiple indoor monitors are helpful, or where a wired, reliable connection over longer distances is required.

It is less suited to users who need 5G WiFi support or who want a purely wireless battery-powered doorbell experience; the product supports only 2.4G WiFi and relies on wired 4-wire installation and external power for locks and monitors.

Pros & Cons

• App notifications and remote unlock via TuyaSmart let you answer the door from anywhere.

Cons

• Supports only 2.4G WiFi, so users with 5G-only networks will need to adjust their router or use a 2.4G network.
