What Is a Video Door Phone System?

A video door phone is an electronic visitor-management and entrance communication system consisting of an outdoor door station and one or more indoor monitors or management interfaces.

A typical operating sequence is: Visitor presses call button → Outdoor camera and microphone activate → Indoor monitor receives call → User views and communicates with visitor → Door release is activated when access is approved

Depending on the model and system architecture, communication can occur through dedicated wiring, an Ethernet network or Wi-Fi. A complete system can include:

Outdoor video door station
Indoor monitor
Camera and microphone
Loudspeaker
Call button
Door release relay
Ethernet/network connection
PoE or DC power supply
Electric lock
Exit button
Mobile application
Access-control integration

A standard doorbell normally provides only an audible or mobile alert. A video door phone adds live video, two-way voice communication, visitor verification and controlled door unlocking.

For installations where visitor control must work together with employee or restricted-area entry, Safelincs also provides Hikvision access control systems including electronic locks and access-control devices.

Main Components of a Video Door Phone System

1. Outdoor Video Door Station

The outdoor station is installed at the gate, main entrance, apartment entrance or other controlled access point. It acts as the visitor-side interface of the video intercom system. Depending on the model, an outdoor station may include:

HD camera
Wide-angle lens
Infrared illumination
Microphone
Speaker
Call button
Relay output
RFID card reader
PIN keypad
Tamper protection
Weather-resistant enclosure

Camera specifications may vary between models. Resolution, field of view, WDR performance and low-light capability determine how clearly visitors can be identified under different lighting conditions.

Outdoor installations should also consider the IP protection rating of the enclosure. Models designed for external installation may use weather-resistant housings such as IP65 or similar protection levels, but the exact rating should always be checked on the selected model.

2. Indoor Monitor

The indoor monitor is the main user interface for answering visitor calls. Common monitor configurations can include:

7-inch or 10-inch display
TFT/LCD display
Capacitive touchscreen
Microphone and loudspeaker
Two-way audio
Live outdoor-station view
Door-unlock controls
Snapshot or recording support
microSD storage on supported models
Alarm inputs/outputs
Ethernet or Wi-Fi connectivity

In larger systems, multiple indoor monitors can be assigned to different rooms, offices or apartments. Certain IP-based systems can also display compatible network camera feeds, allowing the indoor monitor to serve as part of a broader security interface.

For properties requiring continuous security-camera monitoring, explore Safelinc's CCTV surveillance cameras and systems.

3. Door Lock and Relay Control

A video door phone does not normally unlock a door mechanically by itself. Instead, an integrated relay or access-control interface sends an electrical signal to the connected locking system. Compatible door hardware may include:

Electromagnetic lock
Electric strike
Electric bolt
Automatic gate controller
Electric gate lock

Additional access-control components may include:

Lock power supply
Exit button
Door-contact sensor
Emergency break-glass unit
Access controller
Relay module

The relay may operate using Normally Open (NO) or Normally Closed (NC) contacts depending on the lock and security design. When designing a video door phone with lock, the lock voltage, current requirement, relay capacity and fail-safe/fail-secure operation should be checked before installation.

Network and Power Requirements

Modern IP door-phone systems use structured network infrastructure similar to many IP surveillance systems. Typical components can include:

Cat5e cable
Cat6 cable
PoE switch
Ethernet switch
PoE injector
12V DC power supply
Router
LAN infrastructure

For new structured installations, Safelincs provides Cat6 network cables that can be used for compatible Ethernet-based security and networking systems.

Power over Ethernet

With compatible equipment, Power over Ethernet (PoE) carries network data and electrical power over the same Ethernet cable.

Typical architecture include: Outdoor Station → Cat6 Cable → PoE Switch → LAN

This reduces the need for a separate power cable to supported devices. However, PoE compatibility must be checked carefully. Depending on the system, equipment may support standards such as IEEE 802.3af or IEEE 802.3at, while some manufacturers may use specific powering requirements. Safelincs also supplies Dahua PoE switches for compatible network-security installations.

Types of Video Door Phone Systems

1. IP Video Door Phone

An IP video door phone transmits video, audio and signaling through an Ethernet/IP network. Typical features can include:

TCP/IP communication
