What is a Video Intercom and How Does It Work?

A sistema di citofono video is a communication device that allows audio and visual interaction between individuals in separate locations — typically between a visitor at the entrance and a resident inside a building. These systems are commonly used for:

• Residential gate and door security
• Complessi di appartamenti
• Edifici commerciali e uffici
• Warehouses and industrial facilities

🔧 Key Components of a Video Intercom System:

Componente	Funzione
Unità esterna	Installed at the entrance; includes camera, microphone, and call button
Monitor interno	Allows residents to see and talk to visitors
Alimentazione	Powers the system (wired or PoE)
Unità di controllo	Manages communication between devices
Wiring or WiFi	Facilitates signal transmission

🧠 Come funziona:

• Un visitatore preme il pulsante di chiamata sull'unità esterna.
• The video signal is transmitted to the indoor monitor.
• The resident can view, speak, and optionally unlock the door.

Some systems are standalone and work independently, while others connect to cloud servers for remote access via smartphone apps.

Can Video Intercom Work Without Internet?

Sì, video intercom systems can work without internet, especially those designed for offline or local area communication. These are usually sistemi cablati o wireless systems operating via local RF or LAN connections.

This type of intercom is ideal for:

• Buildings with limited or no WiFi access
• Sites with strict data privacy requirements
• Users who prefer not to rely on cloud services

🔍 Types of Video Intercom That Work Without Internet:

Tipo	Internet Required?	Come funziona	Ideale per
Wired Analog Intercom	❌ No	Uses coaxial or 2/4-wire cabling	Apartments, villas
Wired IP Intercom	❌ Optional	Uses LAN for internal communication	Offices, campuses
Wireless RF Intercom	❌ No	Uses radio frequency (RF) communication	Remote areas
WiFi-enabled Intercom	✅ Sì (per remoto)	Requires internet for mobile app access	Smart home

✅ Offline Use Scenarios:

• Local communication only (e.g., between entrance and reception)
• No need for mobile app or cloud video recording
• Lower risk of hacking or privacy breaches

However, without internet, the system cannot:

• Send notifications to smartphones
• Allow remote unlocking via app
• Store video footage on cloud
