And its consequences for Modern Security Surveillance

Traditional door phones were the preferred method for simple visitor communication for many years.  One thing they did was permit someone at the building’s door to make a call to someone inside. However, contemporary structures, businesses, and residential neighborhoods no longer run on “basic.”  Technology has advanced far beyond a basic button-and-buzzer configuration, security concerns have altered, and user expectations have shifted.

These outdated devices are being quickly replaced by cloud-based intercom systems, which are changing how building management platforms, access control systems, and security surveillance cameras interact.  The intercom is now more than simply a means of communication.  It is now an intelligent, cloud-based, video-capable security endpoint that connects to mobile devices, cameras, analytics, and credentials.

What Changed with the Rise of Cloud-Based Intercoms?

Conventional door phones had limited functionality, local-only connectivity, and analog circuitry.  They don’t provide flexible access control or remote visibility, are prone to failures, and need on-site maintenance.  These older technologies began to reveal their age as buildings got more intelligent and interconnected.

Outdated hardware is replaced with cloud-based intercoms, sometimes known as IP video intercoms, with:

• Access to the internet
• Live video
• Access to mobile apps
• Cloud storage
• Management from a distance
• Astute integrations
• Automatic firmware updates

Alongside IP cameras, door access systems, visitor control software, alarms, WiFi networks, and cloud video management systems, they act as part of a building’s larger ecosystem rather than as standalone devices.

With older equipment, this degree of integration was not feasible.  Additionally, the shift to cloud-based solutions is becoming unavoidable as more automation and visibility are required for both residential and commercial premises.

Market Trends Driving the Shift

The replacement of outdated door phones is being accelerated by several industrial trends:

1. The Smart Building Boom

Smart building technologies: Systems that monitor, automate, and optimize building functions are being used by property developers and facility managers throughout the globe.  Because cloud intercoms offer digital credentials, automated guest flows, and remote control, they perfectly integrate into this ecosystem.

2. Mobile-First User Expectations

Residents anticipate using their phones to respond to guests.  Even when employees are off-site, commercial tenants want them to handle deliveries.  Remote visibility is what property managers desire.  These evolving expectations are supported by cloud intercoms through:

• Mobile applications
• Two-way video and audio
• Push alerts
• Visitor records and access logs

 Conventional door phones are just unable to keep up.

3. A greater focus on liability and security

 All sectors now have stricter security regulations.  Structures require:

• Video recordings
• Unambiguous audit trails
• Verification of identity
• Combined surveillance

 Improved responsiveness to incidents

These needs are met by cloud intercoms in conjunction with contemporary IP security cameras, which offer time-stamped video logs, cloud recording, and remote review.

4. Off-Site Management and Remote Work

Security operators, IT departments, and property managers no longer operate exclusively on-site.  Cloud-based systems enable:

• Administration from a distance
• Managing users from any location
• Quick lock/unlock
• Troubleshooting remotely
• Monitoring via remote camera and intercom

 This capability has become essential for modern operations.

5. Reduced Maintenance and Cost Effectiveness

 Cloud intercoms have fewer moving parts and no on-premises servers, which lowers:

• The cost of installation
• The expense of wiring
• Hardware malfunctions
• Service calls made on-site
• Downtime
• Costs of upgrades

Physical repairs and part replacements are necessary for traditional systems.  Only software upgrades and sporadic hardware inspections are necessary for cloud systems.

Why Security Surveillance Cameras and Cloud Intercoms Work Better Together

Cloud intercoms and security cameras are now a single, integrated solution.  Together, they provide enhanced visibility, more robust verification, and a comprehensive access control experience.

1. Video Verification in Real Time

You can see directly who is asking for access thanks to a cloud-based intercom with built-in video.  However, adding more IP cameras to that intercom provides complete context:

• Is there a tailgater?
•  Do they have anything in their hands?
• Are they attempting to conceal who they are?
• Is there somebody hanging around the door?

 This degree of situational awareness is not possible with traditional door phones.

2. Cloud VMS Integration

Cloud video management systems (VMS) may be synchronized with contemporary intercoms. This permits:

• The smooth synchronization of camera video and intercom events
• Quick clip retrieval
• Timelines that can be searched
• Centralized oversight

 These days, forensic investigations may be completed in minutes instead of hours.

3. AI and Analytics

 Features of contemporary security cameras include:

• When allowed by law, facial recognition
• The detection of loitering
• Classification of people and vehicles
• Recognition of license plates
• Heat maps of motion
• Alerts for behavior patterns

These analytics can inform security professionals, lock doors, and notify the intercom system when they are activated.

4. Remote Access & Centralized Monitoring

From a single dashboard, security teams may see camera feeds, intercom calls, and logs.  

This is particularly beneficial for:

• Multi-building campuses
• Gated communities
• Retail chains
• Storage facilities
• Academic institutions
• Business establishments

Everything that was previously dispersed across several devices is centralized via cloud systems.
