In any apartment building, communication and security are key. Residents want to feel safe, and building managers need to keep track of who’s coming and going. That’s where intercom systems and video door phones come in. These systems help people inside the building communicate with visitors, grant access, and stay aware of who’s at the door—all without opening it. In this post, we’ll break down how these systems work and why they’ve become a standard part of apartment living.
An intercom is a device that lets people talk to each other inside a building without using a phone. In apartment buildings, intercoms are used for two main reasons:
- To communicate with visitors at the main entrance, and
- To communicate between units or with building staff.
Traditional intercoms use audio only, while newer systems include video and app-based features.
A basic apartment intercom system has three main parts:
- Entrance Panel: Located at the main gate or lobby, it lets visitors call a specific apartment.
- Indoor Unit: Placed inside each flat, this device receives the call. The resident can answer and speak with the visitor.
- Electric Door Lock: This connects to the system and allows residents to unlock the main door remotely with the press of a button.
Modern systems may also connect to a smartphone app so residents can answer calls even when they’re not home.
A video door phone is an upgraded intercom system that includes a camera, allowing residents to see who is at the door before letting them in. It’s a great way to improve security, especially in buildings with high foot traffic or delivery activity.
Video door phones usually include:
- A doorbell camera at the building entrance or apartment door
- A video screen inside the apartment
- A microphone and speaker for two-way audio
- An unlock button to open the door remotely
Some models come with motion sensors, night vision, and recording capabilities for added security.
Today’s intercoms and video door phones go beyond basic audio. Here’s what many systems now offer:
- Mobile App Integration: Residents can get calls and video feeds on their smartphones.
- Call History & Snapshots: See who rang your bell, even if you weren’t home.
- Touchscreen Interfaces: Sleek, easy-to-use indoor units with high-res displays.
- Multiple Entry Points: Control access at gates, lobbies, and even parking areas.
- Visitor Logging: Useful in gated communities to track visitor history.
These features are especially helpful in buildings with many units or security-conscious residents.
- Security: See and speak to visitors before opening the door. Prevent unauthorized entry.
- Convenience: No need to walk to the gate—just answer from your couch or phone.
- Privacy: You can ignore or block unknown callers easily.
- Control: Know when maintenance staff, deliveries, or guests arrive.
- Community Management: Building staff and guards can also use the system to contact residents when needed.
For apartment owners, these systems also add value to the property and are a selling point for tenants or buyers.
There are two main types of installation:
- Wired Systems: More stable and secure, often installed during construction. Ideal for large apartment complexes.
- Wireless Systems: Easier to install in existing buildings. Uses Wi-Fi or radio frequencies. Some offer video calling via mobile apps.
Both systems can include features like remote unlocking, recording, and integration with home automation.
When selecting an intercom or video door phone system, consider:
- The number of units in the building
- Whether the system should connect to smartphones
- If you need video monitoring or just audio
- The range of the system (important in large buildings)
- Your budget and installation space
Intercoms and video door phones are no longer luxury add-ons—they’re essential for secure, convenient apartment living. These systems give residents control over who they let in, while improving communication and peace of mind. Whether you’re upgrading an old building or moving into a new one, installing a reliable communication system is a smart step toward safer, smarter living.
