How Intercom Systems Increase Office Security


What Is An Intercom System?

The complex definition: Intercom systems are two-way communication electronic devices that contain circuitry for the purpose of transmitting and receiving audio and/or video transmissions.

The basic definition: An intercom system is a way to communicate with someone in another office or location using voice or video calls.

Now, let’s get to the important part and figure out which intercom system is the best one for you.


Intercom System: Key Considerations for Offices and Businesses

Intercom systems help solve a lot of issues around safety, security, productivity, access control, and visitor management for offices of every kind. But there are a lot of features, functions, and considerations to consider before deciding which intercom system is the right solution. Do you need access control built-in to your video intercom system? Is face recognition a priority? Is visitor management important? The following checklist details what questions you should be thinking about before buying an intercom system.

Wired vs. Wireless Intercom System

Wired intercom systems typically have less issues with connectivity as they have a direct Ethernet connection.

Wireless intercom systems do not require invasive installation however outside interference and environmental factors make for less reliable connectivity.

Doorbell Feature 

The simplest solution is to just buy a battery powered doorbell, however it’s operationally very cumbersome, since you have to walk to the door everytime it buzzes, which is a huge pain point. 

Audio Intercom

If you want to be able to perform audio calls to visitors, then you need to make sure your intercom has an audio component that allows for two-way calling. 

Video Intercom 

A video intercom component is necessary if you want to be able to visually verify who is at the front door and perform two-way video calls. 

Video intercom systems can offer one-way or two-way video capabilities that allow for secure visual verification of all visitors and anyone requesting access at the front door.

Access Control Integration

The best intercom systems integrate seamlessly with access control by utilizing face recognition and mobile app unlock. This comprehensive solution enables modern access that securely authorizes visitors, tenants, and employees. 

Weatherproofing

Depending on where you’re located and if inclimate weather is a reality, ensuring weatherproofing is a must if you want to install an intercom station outdoors. 

Scalability  

The number of channels you need will depend upon the number of locations or offices you need to connect

Automatic Door Unlock

Automatic door unlock capabilities allow remote unlock from anywhere and can be extremely useful for managing visitors, vendors, janitorial services, and more without needing face-to-face interactions. 

Remote Visitor Management

Remote functionality will allow you to pick up calls and grant access from anywhere using just a mobile phone, browser, or desktop cloud-based dashboard.  

Administrator Permissions

Do you need to be able to assign multiple admins and easily update administrator permissions? Cloud-based video intercom systems will allow for easy, streamlined admin controls and permissions.

Hardware Cost

It’s important to identify budgets up front because intercom systems and the corresponding hardware can range from affordable to expensive — and expensive doesn’t always mean better. Some intercom systems will require upfront costs to buy hardware, and other options will allow leasing for a determined and agreed upon contract.

  • Monitor the front door, make announcements, and connect via mobile phones.
  • Provides automatic or remote touchless unlock for individual doors.

Disadvantages

  • Ethernet provides better quality and security, but you’ll need to lay down cables if your facility doesn’t have Ethernet networking installed. Luckily, most offices and multi-tenant buildings already have ethernet wires since it’s the most common format of wiring in buildings.
  • More expensive than single doorbells like Nest or Ring, that do not have built in wired support for unlocking doors.

Conclusion

Swiftlane’s system’s interoperability as video intercom, face recognition, mobile and legacy access control makes it a great choice for residential and commercial buildings as well as offices of all shapes and sizes. Swiftlane is well-suited for enterprises and small and medium businesses that want more security, flexibility, and future readiness from their office intercom systems.

The face recognition feature is optional. The video intercom works as a standalone system, thanks to its wired architecture. Even micro businesses can use it as a video doorbell and remote unlock system. Strong privacy controls built for data, with SOC II certification, secure transfer and storage of data.


Aiphone Intercom

Aiphone is one of the most respected brands of security communication systems. They have an extensive range of intercoms and related products. The product lineup includes peer-to-peer IP intercoms, hardwired intercoms with IP capability, multi-tenant intercoms, app capable video intercoms, emergency intercoms, intercom doorbells, and more.

Aiphone Intercom Series Overview

IX Series (Peer-to-Peer Intercom): With a capacity of 5000+ door stations and 5000+ master stations, the IX Series is a simple, network-based intercom calling system through SIP.

IXG Series (Multi-Tenant Video Intercom): With a system capacity of 9999 devices including physical stations, gateways, and lift control adaptors, the IXG Series is a scalable visitor management solution that allows visitors to call building tenants from a directory. Tenants can receive calls from in-unit stations, or now via mobile device.

JP Series (Touchscreen Intercom): A simple, touchscreen video intercom for room to room communication.

JO Series (Video Intercom with Mobile App Capability): This video doorbell supports 2 door, 2 monitors, and 8 mobile devices for two-way audio and one-way video communication between hardwired stations. Tenants can also receive calls from their mobile device.

GT Series (Multi-Tenant Security Intercom): Finally, the GT Series is compatible for additional security purposes. The GT Series can include up to 5 entrance stations, 2 video guard stations, and 48 tenant stations. Guard stations can connect multiple sites, monitor the built-in PTZ cameras, and forward incoming visitor calls to tenant stations.

Advantages

  • Series models cater to different industry needs with specific user features, creating a solution for any need
  • Reliable hardware and connectivity
  • Hardwired in-unit stations make visitor accessibility easier than ever

Disadvantages

  • Only the IXG, IX and JO Series are cloud based and offer a mobile app for management
  • Most Aiphone models are network-based, local systems that can only be managed from inside the building
  • Need for on-site monitoring and maintenance
  • Lack of two-way video calling depletes visitor experience at the door
  • Visitor engagement prior to the time of visit, such as pre-registration, one-time access pin code, and health screenings are not available.

Conclusion

Aiphone intercoms offer solutions for virtually any need or industry. Their systems are reliable and do not require add-ons to perform their functions. While standard in functionality, it would, however, be hard for Aiphone to generate an engaging and hospitable visitor experience with the lack of engagement at the door or prior to the time of visit.

DoorBird Intercom

DoorBird Intercom is a German-built video doorbell system. DoorBird Video Intercom is a high-end doorbell intercom system that easily connects with access devices like electronic doors and gate controls. DoorBird is unique in that it replaces a traditional doorbell with an IP-based system.

DoorBird Pricing

Depending on the products you choose, a single Doorbird Door Station will cost between $384 for a simple home IP doorbell and $2,502 for an IP video door station for multi tenant buildings. 

The indoor station costs $505. 

There are no charges for the automatic cloud storage of entry photo logs for the 50 most recent motion sensor events. An annual subscription of $53+ has 7-day HD storage, if required.

Key Features

  • Simple installation: built-in connectors for traditional door chime, Ethernet, electric door strike, and door opener button
  • Remote unlock function through DoorBird mobile app
  • Sends photo records of visitors to the cloud where they can be accessed through the DoorBird app
  • 4D motion sensor and infrared Night-Vision
  • Each video doorbell can connect with up to 8 iOS or Android phones or tablets

Advantages

  • Works on eight devices simultaneously 
  • Ultra sharp, 180-210 degree ultra wide angle HD image, straightened and without black fish eye edges
  • Aesthetically designed, durable, and high-quality video doorbell
  • Open API and extensive integration options including NVR, VMS, NAS, RFID, and a range of smart locks and smart home systems

Disadvantages

  • Door relays included in the intercom, such as DoorBird, pose a security risk*
  • Limited access control functionalities
  • No built-in SIP or PBX connectivity, can only send push notifications to non-IP phones
  • Camera lens should be at a minimum height of 57 inches, compared to the ADA compliance height of maximum 48 inches

*Door relays that are programmed into the intercom can be removed from their mount to connect the relays, which would trigger an unauthorized door unlock. Typically, more intercom devices avoid this by having a separate device on the secure side of the building that triggers door unlock.

Conclusion

DoorBird is an innovative and convenient video doorbell designed for small to medium sized operations. It has a compact and sleek design with simple installation. However, as an access control system, DoorBird does not offer a comprehensive solution and should undergo close consideration for implementation when access management and security are a factor in implementation.

Latch Smart Lock

Latch is a U.S. based innovator that started with locks and has evolved into a video intercom and access control system. It is positioned as a complete building system and contains hardware, software and services to make buildings better for everyone. 

Latch Intercom Pricing

The visitor entry intercom is priced at $2,999, and you need to buy an external camera for video. Latch charges $2 monthly per unit as software fee. Pricing may vary by number of units and contract length.

  • Doors can be unlocked by a key, a passcode, or remotely through a smartphone 
  • The system  allows for temporary codes for guests, delivery people and cleaning crews.
  • Beautiful door lock that even has a keyhole if you want to enter the old fashioned way
  • Each smart door lock comes with a built-in camera for image capturing during entry
  • Optional property management features including Ecobee climate control, Leviton smart light switches, and  Sonos sound based access

  • Comes with optional energy saving tools, visitor access, deliveries, and sound-based access
  • Built-in camera with every door, and entry photos are synced to the cloud

  • External camera required for video calling
  • Does not mention support for key card system
  • No health check or remote screening tools available for compliance with CDC/OSHA COVID safety guidelines
  • The intercom page does not mention support for PIN based unlock. It’s unclear whether one-time use pins for delivery can be granted ahead of time
  • The website does not mention if multiple admins can be assigned for a unit or commercial tenant
  • The intercom is a part of the Latch full-building solution, which requires a two-year service contract
  • Face recognition is not available
  • Powering using PoE would require POE+ with 55W+ power. Just POE enabled switches do not support that much power from a single output, so you would need to make sure you use a POE Switch that supports 55W on a single port

Conclusion

Latch is a great system for small and large buildings, particularly residential. Latch intercom integrates with Latch front door devices and software, so users need to buy the complete system to use the intercom for access control.

Increase Safety and Security with Office Intercom Systems

Employee safety and security is the most important reason to integrate an office intercom system into the workplace. Now, modern solutions are making it even easier to do just that.

But, what if you have an old or outdated intercom? What replaces old intercom systems?

Modern intercom systems that operate from the cloud can easily replace outdated systems and are quick to install and deploy (especially if the system allows the users to use mobile credentials instead of key cards) so there is no gap in security. The cloud also offers better visibility with real-time data and reporting on top of additional layers of security and advanced functionality that wasn’t available before.

Here’s how offices and workplaces are using modern intercom systems.

office intercom system

1. Quick Interoffice Communications

Interoffice communication (or intercom) systems are the best way to make announcements or send notifications to anyone in the office instantly.

2. Make General or Emergency Announcements

Intercom systems can be joined with public address systems to send out informational or emergency announcements, such as at airports or healthcare facilities.

3. Ramp Up Security and Surveillance

Video intercom systems that come with speakers and microphones can be used to complement video surveillance systems at certain facilities. The security team can make a cautionary announcement after observing a person entering a prohibited area, such as a section of the building that has been closed because of fire or infection risk.

4. Mobile Communication

High-end intercom systems can integrate with iOS and Android devices and allow the caller to speak to a person even when they’re not in the office.

5. Controlled Access Points

Intercom systems provide a simple but reliable form of remote access control when you don’t want to issue key cards to employees or tenants. A person can remotely unlock the door from inside the building or from anywhere if an Ethernet based or wireless IP video intercom is being used, after speaking to the visitor or after visual verification.

6. Grant Access for Janitorial or Deliveries

Cleaning services or deliveries may arrive at odd hours. IP intercoms allow security teams to unlock doors remotely from anywhere and allow entry without having to come to office. Modern cloud-based facial recognition video intercom and bluetooth access control systems can be programmed to allow automatic scheduled access to visitors.

7. Integration With Electronic Locks

Sometimes the intercom is integrated with a keypad that automatically unlocks the door after an authorized person enters their personal identification number or PIN. However, use of common touch surfaces including office entry keypads should be avoided in post-COVID-19 workplaces.

8. Integration With Touchless Access Control

Touchless access control systems come with video intercom systems built in and can provide a safer way to enter offices. The door automatically unlocks to grant access when the face credentials of a visitor match authorized credentials. When the user is not registered on the face recognition database, they can simply speak to the front desk via video intercom and can be allowed to enter the office.
