Top Considerations for Buying an Intercom for Business

Many people thing they are just looking for an audio calling device and a button to let someone in. But they end up spending all day walking over to a buzzer and back, and letting people in. Most offices get upwards of 6 deliveries a day, and growing. Increase in online ordering and food delivery has made the problem worse. Consider the following factors and goals when purchasing a new system:

  • Wireless Intercom vs Wired Intercom: This refers to the receiver end of the communication. Do you want a system that’s wired to a receiver on your desk? Or something that calls your phone or computer, even when you are working from home or moving around in the office?
  • Cost: Most business intercom systems cost between $2400-$5500 with hardware and installation. Do you have the budget to get these installed, or are you looking for a simple doorbell chime? The doorbell chime is very cheap, and will just play a ring inside to let you know that someone is outside. You have to walk over and open the door. Only good for very small office with a dedicated front desk person.
  • Audio vs video intercom: These days, video intercom systems cost the same, or cheaper than traditional audio intercoms. An audio intercom also requires a telephone line to be purchased and paid monthly. Video intercoms will provide higher security, by showing you who is at the door before letting them in.
Three Types of Intercom Calls
  • Door release: Do you need the ability to release the door remotely. This intercom would act like a door buzzer system for your business, and release the door remotely, without having to walk over to open the door.
  • Calls to your phone: Do you need the ability to call your phone using a telephone call or app based call? Office managers are busy people – you wear so many hats, and constantly moving around. I think it’s liberating to not be stuck to the front desk all day.
  • Support for tablets and computer: Wireless calls are liberating. In addition to that, it may be important to receive calls on a tablet or computer, so that it supports device options for all people added to the intercom

  • Single tenant vs multi-tenant intercom: If installing outside a multi-tenant commercial building, the intercom must have the ability to display a directory of tenants.
Swiftlane Intercom
  • Fallback intercom calling: When you are busy running around, or out for lunch, it’s nice to have the ability to lean on a second person to handle visitors. With modern business intercoms like Swiftlane, you can set up a fallback person in case you are busy and can’t handle the visitor at the moment.
  • Route to multiple people: Often, it’s a beneficial feature when the intercom dials multiple people in parallel. This way, the likelihood of picking up the calls goes up, and you don’t leave important guests stranded outside the door.
  • Support telephone and desk phone numbers: Modern video intercom systems for business allow making VOIP based telephone calls to a cell phone or desk phone. Even zoom and Microsoft team phone numbers. You can press 9 to unlock the door. This capability ensures that all employees can choose the device their prefer. E.g. This is useful if someone does not want to use their personal cell phone data to take video calls.
  • Data Security: Is your data being protected? Does the vendor have data security audits, like SOC2 certification, to prove external verification of their data privacy and security practices?
  • Handle deliveries: Can you give access to delivery people? E.g. Can you generate unique PINs for your Fedex, UPS and USPS drivers? Does the system store
  • Temporary PINS: May be you have clients, interview candidates, cleaners etc coming in at all day long. Does the system give you the ability to temporary use PIN codes using the mobile app?
  • Shift (Schedule based) calling: Do you only want to receive visitor intercom calls when you are at work? Instead of getting calls at 2 AM? Does the system allow you to set up a schedule based calling for employees and front desk staff?
  • Vandal & Weather resistance: These intercoms mount on the building exterior. Does the system have protection from vandalism? E.g. What’s the IK vandal rating for the system? It goes on a scale of 1 – 10, 10, 10 being the most vandal protection for the hardware.
  • Employee Access Features: Can the intercom also grant and manage access to employees and contractors? E.g. Modern intercoms provide touchless face recognition access, mobile app based access and key card access through the same intercom device. This reduces your cost of running access control for employees.
  • Remote management: Can you change settings or directory in the intercom remotely from a web browser? Or do you have to connect locally through a cable or local IP address in order to program this system?
  • Works along side key card system: Does the system work alongside your key or key card based access to the building?
  • Support for elevators, gate, etc: Sometimes, you need door release to multiple areas. e.g When a visitor is standing at the front door, you may need to unlock both the front door and then elevator.

Installation: Swiftlane intercom retrofits alongside existing electric door locks and motion sensors. Swiftlane intercom reader requires simple ethernet-based wiring, using standardized cables and avoiding proprietary wiring. Swiftlane takes a single power over ethernet cable to install the reader.

Hardware: SwiftReader comes in a compact, easy to mount intercom system with a sleek silver-gray or matte-gray design and touchscreen interface. The SwiftReader X comes with optional weatherproof casing and is IK07 impact rated for vandal resistance. Swiftlane door unlock relay sits on the secure side of the building, which means it is not vulnerable to outside security risk. Swiftlane hardware works with existing electric door locks reducing dependence on proprietary hardware as it reuses the majority of the hardware already in place.

Swiftlane Features

  • Video and audio intercom: Ability to receive video calls on the mobile app, iPad, Android tablet or computer. Also, support regular telephone call intercom, VOIP and Zoom phone.
  • Easy to manage from anywhere: Swiftlane is a cloud based system. The receptionist can be on the go or remote and still pick up calls. The directory can be managed remotely through a web browser.

  • High-Quality Video: Swiftlane video intercom provides adaptive 1080 P HD video calls, offering a seamless visitor management experience for your guests.

  • Effective Delivery Management: Issue single-use pin codes to help guarantee convenient, high-security deliveries. These pin codes expire after one use to avoid unauthorized access.
  • Front Desk, Reception and Multi-Tenant Intercom Support: Easily call the front desk with Swiftlane intercom. Multi-tenant intercom settings allow creating an unlimited number of recipients and giving them the ability to receive calls from their visitors easily on their phones.
  • Wireless Intercom for Offices and Enterprises: Because Swiftlane users can receive their visitor calls straight on their phone, there is no need to mount a tablet on the wall or answer a door buzzer in person. This avoids expensive installation costs and hassle around letting people in.

    • Eliminate constant cost of creating new keys and key fobs
    • Eliminate cost of printing visitor badges

DoorBird Intercom

Doorbird Intercom Review

DoorBird is a German-built doorbell system, providing several different types of intercom readers. DoorBird Intercom installs by disconnecting the current doorbell system and connecting the wires to the inputs on the DoorBird device. It can then be connected to WiFi and operated from the mobile app. Doorbird is popular among small apartments, and not so much as a commercial video intercom.

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 office 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.

DoorBird 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

DoorBird Review


  • 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 systems
  • Doorbird products come in variety of sizes and form factors. New DoorBird models are aesthetically very appealing and come in up to 50 different shades.
  • DoorBird provides products at flat hardware cost, with no subscription needed to use the base product. This provides customers with the ability to purchase it upfront without any recurring cost.
  • Impressive weather-proofing


  • 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

IPVM reported that DoorBird suffers from the following issues:

  • Noisy Audio: even though the product comes with noise cancellation, it does not seem to be effective
  • Poor image quality: high compression, poor WDR performance and focus mainly on nearby objects.

*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.

Latch Intercom

Latch is most notably known for its line of smart locks, but has just introduced its multi-tenant intercom system in the past few years.

Latch Price

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.

Latch Features

  • Latch Hardware: Eliminates the need for buying additional hardware and software.
  • Visitor Access: Allow and share access through the Latch App. The system allows for temporary codes for guests, delivery people and cleaning crews. Multiple entry methods include mobile app, NFC, passcodes, and keys.
  • Video Intercom System: Building tenants can choose how their name is displayed on screen and whether or not to share their video and photo.
  • Security: Security integrators have expressed concerns about door lock relays that are directly attached to the intercom system. Relay triggers on the intercom device can provide a security vulnerability to an intruder. By removing the intercom device from the wall and connecting the two relay wires, someone can open the door electronically.

Latch Review


  • Integrated intercom, access control and building management system
  • Restrict video streaming and choose custom display names
  • Multiple entry methods including mobile app, NFC, passcodes, and the good old metallic key
  • Comes with optional energy saving tools, visitor access, deliveries, and sound-based access
  • Innovative door lock design


  • Needs an external camera for video calling
  • The intercom is a part of the Latch full-building solution, which requires a two-year service contract
  • 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

Benefits of Intercom in Offices and Businesses

Employee safety and security is always the top priority in the workplace. But beyond enhancing safety and security, intercom systems also offer other benefits for office buildings and businesses that drastically improve efficiency, decrease overhead, and minimize expenses.

Highlighted below are the main ways video intercoms are increasing office safety and security:

Secure Visitor Management

Intercoms give businesses and enterprises a seamless way to manage visitors in the building by supporting access for personnel ranging from clients to cleaning staff. Video intercom used for business is the best and most efficient solution for monitoring and keeping track of who is in the building, when they have access, or whether their access is authorized.

Contactless Sign-In

Video intercom used in the enterprise setting is a professional and COVID-safe way to welcome visitors without additional check-in or face-to-face interaction with building staff.

Seamless Temporary Access

Office intercom systems allow administrators to create PINs, QR codes, and other unique IDs for intermittent visitors to the building such as cleaning or maintenance staff. This access can be programmed on a schedule basis to control access remotely throughout the facility 24/7.

Access Event History

Accessing event history with a high-traffic building such as an office can be critical in managing compliance and other regulatory matters. It also allows administrators to be proactive should there be any irregularities in access events or at certain access points.

Secure Deliveries

Offices and businesses regularly receive confidential and important business-related deliveries. This can be client documents or internal business matters. Whether intercepted with malicious intent or otherwise, package theft can be detrimental to an organization. Regardless of the content, office intercoms mitigate the risk of theft by ensuring that delivery personnel always have secure access to the building to delivery packages.

Built-In Access Control

Some office intercom systems also offer built-in access control systems. A built-in access control system makes it easy for office buildings to manage employee access and visitor management under one platform. A single platform for managing access is much more secure than two different siloed systems that operate independently of one another. Data privacy is increased with just one system. Administrators and security teams are also able to retrieve better data and reporting of access events and activity.

Office Intercom Components

There are several components to an intercom system for office buildings and businesses including both hardware and technology. It’s important to talk about each component to make sure you get the system that best fits the needs of your workplace.

First, hardware will always consist of the visitor-facing interface (basically, the system itself), door controller, wiring (if any) and door locks.

The Intercom System

Person Using Swiftreader X Video Intercom

The intercom system itself is the hardware that is placed outside the workplace entrance. Legacy intercom systems are typically large metal structures with buttons and keypads. Modern intercom systems will display a touchscreen and allow visitors to scroll through a directory, make an intercom call to someone in the building, scan a QR code, or type in a PIN code.

Door Controller

Swiftlane door controller hardware 5.1

The door controller connects the doors and provides door unlock capabilities, to grant someone entry into the building or office.


Traditionally, intercom systems required wiring throughout the building’s infrastructure. The wiring allowed the intercom system at the front door to communicate with whoever the recipient was within the building. Installing wiring, however, is time-consuming and expensive. These legacy systems also limit recipients to answering intercom calls from the hardware station the wiring is connected to.

Modern intercom systems do not require any wiring at all. Wireless intercom calls go directly to a smart device or telephone.

Electronic Door Locks

While electronic door locks are not always provided by an intercom manufacturer, they are still a component of an intercom system. The intercom door controller will connect to these electronic locks and be able to trigger a door unlock for visitors. Most intercom systems are able to work with any type of electronic door lock.

Secondly, the technology component of an intercom system consists of the software used to run it.

Intercom Software

Intercom software will vary by company. Each interface will look different and have operational nuances. The important distinction to make with intercom software is whether it is installed manually on local hardware or if it operates off-site from the cloud.

How much do business intercom system costs?

Most intercom systems for office cost between $1400-$5000, depending widely based on the installation type and hardware. Most new intercoms only require wiring the panel at the front, to the internet and power. The door lock power is also connected to it. Installation typically costs between $1200-$1800. Traditional wired intercoms require installing an inside wall tablet, or a desk mounted tablet, which cost more in wiring and hardware costs.

Why You Need an Office Intercom System

Most businesses or offices keep their front doors locked all day or part of the day. All kinds of visitors come to an office. Video intercom systems should help meet the following scenarios:

  • Communicate with visitors at the front door
  • Grant entry to clients
  • Allow delivery drivers with access to the building
  • Corporate offices may have Interview candidates coming in
  • Larger offices may have multiple entrances and only one or no dedicated front desk person
  • Offices need to buzz people remotely through many entrances.
  • The intercom system may also provide access control for employees
