Video Intercom vs Audio Intercom: Which Is Right for Your Property?
Choosing between a video intercom and an audio intercom depends on how much visibility, convenience and access control you need at your front door, gate or business entry. Both systems allow communication with visitors, but they suit different property types and budgets.
An audio intercom lets you speak with visitors before granting access. A video intercom adds a camera and monitor so you can see who is at the door or gate before you respond. Some video intercom systems also support smartphone app access, allowing you to answer visitors remotely where the system is correctly configured.
In this guide, we compare video and audio intercom systems, explain where each option works best, and help you choose the right intercom for your home, unit, townhouse, front gate or business.

What Is an Audio Intercom?
An audio intercom allows two-way voice communication between the door station and an internal handset, monitor or room station. When a visitor presses the call button, the person inside can speak with them before allowing entry.
Audio intercoms are commonly used for:
- Front doors
- Small offices
- Units and apartments
- Internal room-to-room communication
- Simple door entry control
- Budget-conscious intercom upgrades
- Properties where video is not required
Audio intercoms are often chosen because they are simple, reliable and cost-effective. They are ideal when you mainly need to speak with visitors rather than visually identify them.

What Is a Video Intercom?
A video intercom includes a camera at the door station and a screen inside the property. When a visitor calls, you can see who is at the door or gate before you answer or release access.
Video intercoms are commonly used for:
- Family homes
- Townhouses
- Duplexes
- Front gates
- Driveway gates
- Small businesses
- Reception entries
- Properties receiving regular deliveries
- Homes wanting smartphone access
Video intercoms provide extra confidence because you can visually confirm who is at the entry point before speaking or granting access.
Video Intercom vs Audio Intercom: Quick Comparison
| Feature | Audio Intercom | Video Intercom |
|---|---|---|
| Main Function | Speak with visitors before granting access. | See and speak with visitors before granting access. |
| Best For | Simple homes, offices, apartments and internal communication. | Homes, gates, families, businesses and properties needing visitor verification. |
| Visitor Identification | Voice only. | Visual and voice confirmation. |
| Smartphone Access | Usually limited, depending on the system. | Available on selected smartphone-enabled systems. |
| Cost | Usually more budget-friendly. | Usually higher due to camera, screen and added features. |
| Security Level | Good for basic visitor communication. | Stronger for visual screening and entry control. |
When Should You Choose an Audio Intercom?
An audio intercom is a good choice when you want simple, reliable communication without the added cost or complexity of video. It may be the right option if you do not need to see visitors and are comfortable identifying people by voice.
Audio intercoms may suit:
- Homes with a clear view of the front entry
- Small offices
- Internal room-to-room communication
- Simple apartment or unit entry points
- Budget-conscious customers
- Properties where video is not required
- Basic door release applications
- Replacement of older audio-only systems

When Should You Choose a Video Intercom?
A video intercom is usually the better choice when you want stronger visitor screening, visual confirmation and the ability to check who is at the door or gate before responding.
Video intercoms may suit:
- Family homes
- Homes with children or elderly family members
- Front gates or driveway gates
- Properties with poor visibility from inside
- Homes receiving frequent deliveries
- Townhouses and duplexes
- Small businesses and reception entries
- Properties where security is a higher priority
- Customers wanting smartphone app access where supported
For most modern homes, video intercoms offer the stronger long-term option because they combine communication with visual verification.
Best Option by Property Type
| Property Type | Recommended Option | Why |
|---|---|---|
| Family Home | Video intercom | Allows visual screening before opening the door or gate. |
| Small Office | Audio or video intercom | Audio may suit basic entry communication; video is better for visitor verification. |
| Front Gate | Video intercom | Helps confirm who is at the gate before release. |
| Apartment or Unit | Audio or video intercom | Audio can suit simple entry; video gives stronger visitor confirmation. |
| Internal Communication | Audio intercom | Simple handset-to-handset communication may be enough. |
| Retail or Reception Entry | Video intercom | Helps staff screen visitors, deliveries and after-hours access. |
Security Benefits of Video Intercoms
The biggest advantage of a video intercom is visibility. You can see who is at the entry point before deciding whether to answer, ignore the call or release access.
Video intercoms can help with:
- Identifying visitors before opening the door
- Checking couriers and trades
- Screening unknown visitors
- Managing front gate access
- Supporting elderly family members
- Helping children avoid opening the door to strangers
- Improving entry control at homes and businesses
- Providing better context when an entry event occurs
For homes where the front door or gate cannot be seen clearly from inside, video is usually the better choice.

Benefits of Audio Intercoms
Audio intercoms remain a practical choice for many properties. They are simple, easy to use and can be more cost-effective than video systems.
Benefits of audio intercoms include:
- Clear two-way visitor communication
- Lower cost compared with many video systems
- Simple operation
- Good option for homes and offices
- Suitable for basic entry management
- Useful for internal room-to-room communication
- 2-wire options available in selected kits
- Can support door release on selected systems where configured
If your main need is to speak to a visitor before unlocking the door, an audio intercom may be enough.
Smartphone Access: Where Video Intercoms Stand Out
One reason many customers now choose video intercoms is smartphone app access. Selected video intercom systems allow you to answer calls, see visitors and manage entry from your mobile phone where correctly configured.
Smartphone-enabled video intercoms may allow you to:
- Answer the door from your phone
- See visitors remotely where supported
- Speak with couriers or trades
- Unlock a compatible gate or door strike where configured
- Receive app notifications
- Check visitor activity where supported
- Manage entry when you are away from home
If remote access and mobile alerts are important, a video intercom is usually the better choice.
Do Audio Intercoms Support Door Release?
Many audio intercom systems can support door release where the correct electric strike, door hardware and wiring are installed. This allows the user to speak with the visitor and then press a button to release the door or gate.
Door release may require:
- A compatible electric door strike
- Correct power supply
- Suitable cabling
- Relay or release wiring from the intercom system
- Professional installation and testing
- Safe exit hardware where required
For simple entry communication with door release, an audio intercom may be suitable. For visual screening before release, video is usually stronger.
Video Intercoms for Front Gates
For front gates, a video intercom is usually preferred because the person inside may not be able to see the visitor from the house. Video helps confirm who is at the gate before access is granted.
Video gate intercoms are useful for:
- Driveway gates
- Pedestrian gates
- Long driveways
- Gated homes
- Townhouses and villas
- Properties with poor front-door visibility
- Homes receiving frequent deliveries
If the intercom needs to release a gate, the correct gate relay, electric strike or access control hardware must be selected and installed properly.
Audio Intercoms for Internal Communication
Audio intercoms can also be useful for internal communication, especially where the goal is simple handset-to-handset communication rather than front-door video screening.
Internal audio intercoms may suit:
- Home offices
- Reception areas
- Workshops
- Warehouses
- Rooms separated by distance
- Properties needing simple communication between two points
Where visibility is not required, audio intercoms can provide a practical and cost-effective solution.
Wired, 2-Wire and Wireless Considerations
Both audio and video intercom systems can depend heavily on the wiring available at the property. Before choosing a system, it is important to check whether the installation is new, existing, wired, 2-wire, IP or wireless-style.
| Connection Type | Best For | Considerations |
|---|---|---|
| Wired Intercom | Permanent installations and reliable long-term use | Requires cabling between stations, monitors or handsets. |
| 2-Wire Intercom | Selected upgrades and simpler cabling projects | Can be useful where compatible existing wiring is available. |
| IP Video Intercom | New builds, renovations and smart entry systems | Often suits video, app access and future integration. |
| Wireless or Wi-Fi Intercom | Difficult-to-wire properties and selected retrofit projects | Performance depends on signal strength, power and network conditions. |
Cost Considerations
Audio intercoms are generally more budget-friendly than video intercoms because they do not require camera and screen components. However, the total cost depends on the brand, wiring, number of stations, door release hardware and installation requirements.
Costs may be affected by:
- Audio-only or video system
- Number of handsets or monitors
- Door station type
- Existing cabling condition
- New cable runs
- Front gate distance
- Electric door strike or gate release requirements
- Smartphone app features
- Professional installation
Choosing the cheapest system may not always be the best result if the property needs video verification, smartphone access or gate release functionality.
Best Brands to Compare
CTC Communications supplies a range of intercom brands for different applications. Audio intercom options include Aiphone and Golmar, while video intercom systems are available across multiple leading brands depending on the required features.
Brands commonly considered for intercom systems include:
- Aiphone: Strong option for premium audio and video intercom reliability.
- Golmar: Practical option for audio intercom and selected intercom applications.
- Dahua: Popular for video intercoms, smartphone intercom kits and connected security systems.
- Hikvision: Strong option for video intercoms, IP systems and app-enabled entry.
- Kocom: Practical option for residential video intercom kits.
- Akuvox: Smart IP intercom option for modern entry and access control-style applications.
The right brand depends on whether you need audio-only communication, video monitoring, smartphone access, gate release, apartment entry or commercial access control.
Video Intercoms and Deliveries
Video intercoms are especially useful for homes that receive regular deliveries. Instead of opening the door without knowing who is outside, you can view the visitor or courier first.
This can help with:
- Confirming courier arrivals
- Giving delivery instructions
- Managing gate access where supported
- Reducing missed deliveries
- Helping family members feel more secure
- Checking unexpected visitors before responding
For delivery-heavy households, a smartphone-enabled video intercom may be worth considering.
Privacy and Simplicity
Some customers prefer audio intercoms because they are simple and less intrusive. Not every property needs video, recording features or smartphone access.
An audio intercom may be the better choice if:
- You only need simple voice communication
- The entry point is already visible from inside
- You want a cost-effective upgrade
- You do not want app-based features
- You want a simple handset system for older users
- You need internal communication rather than visitor video
For elderly users or people who prefer simple technology, an audio handset can sometimes be easier to operate than an advanced touchscreen or app-based system.
Questions to Ask Before Choosing
Before choosing between video and audio intercoms, think about how the system will be used every day.
- Do you need to see visitors before opening the door?
- Is the front door or gate visible from inside?
- Do you want smartphone app access?
- Do you need to unlock a door or gate from the intercom?
- Is the system for a home, office, apartment or gate?
- Is there existing intercom wiring?
- Do you want one handset, one monitor or multiple stations?
- Will elderly users or children operate the system?
- Is simple voice communication enough?
- Do you want future integration with CCTV, alarms or access control?
Common Mistakes to Avoid
Intercom systems should be chosen around the property, wiring and user needs. Avoid choosing based only on price or appearance.
Common mistakes include:
- Choosing audio when visual visitor screening is needed
- Choosing video when a simple audio system would be enough
- Not checking existing wiring before purchase
- Forgetting door strike or gate release hardware
- Assuming every video intercom supports smartphone access
- Installing a door station in poor lighting
- Not considering weather exposure at the door or gate
- Choosing Wi-Fi where a wired system would be more reliable
- Not planning for future extra monitors or stations
- Skipping professional installation for a complex gate or door release setup

Professional Installation Is Recommended
Both audio and video intercoms need correct wiring, door station placement, power supply setup and testing. Video intercoms may also require monitor installation, network configuration, app setup and door release wiring.
Professional installation can help with:
- Choosing between audio and video intercoms
- Checking existing wiring
- Installing door stations and handsets or monitors
- Connecting electric door strikes or gate release hardware
- Setting up smartphone app access where supported
- Testing two-way audio quality
- Checking camera angle and lighting for video systems
- Reducing installation faults
- Explaining how the system works day to day

For modern homes, front gates and businesses, video intercoms provide better visitor verification and can support smartphone access on selected systems.
The best choice depends on your property layout, budget, wiring, visibility, access control requirements and whether you want smartphone features now or in the future.
