Wired 7-Inch HD Video Door Phone Intercom System with Colour Camera and Electronic Unlock

This comprehensive video doorbell intercom system is designed for homeowners seeking a reliable, wired security upgrade. It replaces a traditional doorbell with a dual-unit setup: a robust outdoor colour camera and a clear 7-inch indoor monitor. The system allows you to visually verify visitors via a high-definition screen, communicate hands-free through the integrated intercom, and grant secure access using the electronic door unlock function. With its standard AC power compatibility and included connection cables, it provides a complete, installable solution for controlled entry and enhanced door security, featuring night vision for low-light conditions and adjustable audio-visual settings for personalised use.

Features and Construction

The system's functionality is built around two primary components: the outdoor camera unit and the indoor monitoring station. Each is engineered for a specific role within the home security chain, from capturing a clear image at the door to displaying it inside your home.

Material and Build

The indoor monitor utilises a 7-inch TFT/LCD digital screen housed within a plastic casing measuring 250mm wide by 150mm high by 24mm deep, designed for low-radiation, low-power wall mounting. The outdoor camera is constructed with a waterproof housing to protect its internal components, which include a 1/4-inch HD colour CMOS sensor. This sensor delivers a resolution of 700 TV lines, ensuring detailed image capture for visitor identification.

Size and Practical Fit

The compact dimensions of both units facilitate installation in standard entryway spaces. The outdoor camera measures 138mm x 98mm x 40mm, while its 3.6mm lens offers a 92-degree field of view, which is adjustable to frame your doorstep correctly. The indoor monitor's 7-inch widescreen provides a clear picture without occupying excessive wall space. The system operates on a universal AC power input (100V-240V, 50/60Hz) and includes a 5-meter 4-core cable and a 2-core cable to connect the units over a typical door-to-monitor distance.

Uses and Placement

This system is suited for residential properties where a permanent, wired security and communication solution at the main entrance is desired. It integrates surveillance, communication, and access control into a single interface.

Event or Professional Use

For consistent daily use, the system provides reliable visitor management. The call duration is configurable for up to 120 seconds, and a monitoring function allows continuous viewing for up to 60 seconds after a call ends. The electronic unlock feature can be integrated with an existing electric door strike (not included) for remote door release, making it applicable for small offices or controlled-access residential buildings where verifying identity before entry is necessary.

Everyday Home Use

In a domestic setting, it enhances convenience and safety. The hands-free intercom lets you communicate with delivery personnel, friends, or family without opening the door. The 16 selectable polyphonic ringtones prevent the annoyance of a repetitive doorbell sound. Parents can use the monitor to check on children playing outside, and the night vision capability ensures the camera remains functional after dark, providing peace of mind during evening hours.

Benefits and Buying Value

The value of this video door phone lies in its integration of multiple security functions into a dedicated, hardwired system, which can be more reliable than wireless alternatives over the long term.

Reuse and Low Maintenance

As a wired system with a standard power adapter, it is designed for continuous, long-term operation without the need for battery changes or recharging. The power consumption is efficient, rated at less than 0.5W in standby and under 10W during active calling. The waterproof outdoor camera housing is built to withstand weather exposure, contributing to its durability and reducing maintenance concerns. All essential components for installation are supplied in the package.

Why Choose This Product

This product offers a concrete upgrade from a basic audio doorbell by adding a visual component and access control. The 7-inch HD monitor provides a clearer, larger image than smaller portable screens, and the 700-line camera resolution offers better detail than many basic models. The inclusion of electronic unlock functionality and adjustable settings for image and sound provides a level of customisation and control that meets practical security needs, supported by the provided cables and hardware for a complete installation.
