Video Door Entry System: A Comprehensive Guide

Introduction

A video door entry system is a modern security solution that allows residents and property owners to see and communicate with visitors before granting them access. This system integrates video surveillance, audio communication, and remote access control, making it an essential component of residential, commercial, and industrial security setups.

As technology continues to evolve, video door entry systems have become more advanced, offering features like high-definition cameras, mobile app integration, and biometric authentication. This article explores the functionality, types, benefits, and future trends of video door entry systems in detail.

What is a Video Door Entry System?

A video door entry system, also known as a video intercom system, enables secure entry management by providing video and audio communication between visitors and property occupants. The system typically consists of:

• Outdoor Unit: Equipped with a camera, microphone, and speaker.
• Indoor Unit: Features a monitor and controls for interaction and access control.
• Access Control Mechanism: Allows remote door unlocking through RFID, PIN codes, or biometric authentication.

How Does a Video Door Entry System Work?

1. Visitor Initiation: A visitor presses the call button on the outdoor unit.
2. Video & Audio Transmission: The camera captures live video while the microphone and speaker enable two-way communication.
3. Verification & Decision: The resident verifies the visitor’s identity via the indoor monitor or a connected mobile app.
4. Access Control: The resident can grant or deny entry remotely using the system’s interface.
