1. What Is an Intercom System and Why Share Access?

An intercom system is a communication device used to facilitate audio and/or video communication between different areas of a property or building. These systems are commonly used in:

• Residential homes
• Apartment complexes
• Office buildings
• Industrial facilities
• Hospitals
• Schools

Modern intercoms often include video functionality, mobile app control, and integration with smart home ecosystems. Sharing access to an intercom system means allowing multiple users — such as family members, tenants, employees, or building management — to:

• Receive calls or alerts from the intercom
• View real-time video footage
• Unlock doors or gates remotely
• Communicate with visitors

Why Sharing Access Is Important:

Use Case	Benefit
Households	All family members can respond to visitors from their phones
Apartment Buildings	Tenants can individually manage visitor access
Offices and Warehouses	Staff can monitor and control entry points
Commercial Complexes	Simplifies visitor and delivery management
Elderly Care Homes	Caregivers can remotely check in and respond to calls

Allowing shared access improves convenience, security, and operational efficiency — especially in multi-user environments.

2. Methods to Share Intercom Access: Wired vs. Wireless

Intercom systems come in wired, wireless, or hybrid configurations. The method of sharing access depends on the type of system installed.

Wired Intercom Systems

These systems are physically connected via cables, typically installed in permanent buildings. Sharing access usually involves:

• Installing multiple indoor monitors (substations)
• Configuring master control units for user management

Pros:

• Stable connection
• No Wi-Fi dependency
• High-quality audio/video

Cons:

• Complex installation
• Limited flexibility for mobile access

Wireless Intercom Systems

Wireless systems use Wi-Fi, Bluetooth, or RF signals to operate. They often come with mobile app integration, making it easy to share access digitally.

Ways to Share Access Wirelessly:

• Add authorized users via a mobile app
• Send QR codes or temporary access links
• Set up RFID tags or NFC cards

Feature	Wired Systems	Wireless Systems
Installation	Professional, complex	Easy, plug-and-play
Remote Access	Limited	Full app-based control
Multi-User Management	Hardware dependent	App or cloud-based
Maintenance	Low once installed	Requires Wi-Fi reliability

3. How to Share Access on Smart Video Intercoms via Mobile Apps

Modern smart video intercom systems allow access sharing through dedicated mobile applications. This is the most efficient and scalable method for both residential and commercial settings.

Typical Access Sharing Process:

1. Install the Intercom App
   Most brands offer apps compatible with iOS and Android devices. E.g., Tuya Smart, Hik-Connect, Ring, or custom OEM apps.
2. Register the Main Account
   The main user (admin) sets up the intercom and connects it to the home or office Wi-Fi.
3. Add New Users
   Under app settings, locate “Device Sharing” or “Add Members.”
4. Select Sharing Method:
   • Email invitation
   • QR code scanning
   • Username/Account ID entry
5. Assign Permissions
   Define what users can do:
   • View camera feed
   • Answer calls
   • Unlock doors
   • Modify settings
6. Confirm and Send Invitation

Example: Sharing Access via App (Step-by-Step)

Step	Action	Description
1	Open the App	Launch the intercom’s official mobile app
2	Go to Device Settings	Tap on the intercom device
3	Choose ‘Share Device’ or ‘Add User’	Find the access sharing option
4	Select Method	Choose email, QR, or account ID
5	Set Permissions	Limit roles — admin, viewer, control-only
6	Confirm	The recipient receives access immediately

Additional Tips:

• Enable push notifications for all shared users
• Use two-factor authentication for better security
• Set temporary access for delivery personnel or guests

5. Security Considerations When Granting Intercom Access

While shared access offers convenience, it also introduces potential security risks if not managed properly. Here are some best practices and technologies to ensure safe access sharing.

Key Security Features to Look For:

• Role-Based Access Control (RBAC): Limit what each user can do based on their role.
• Two-Factor Authentication (2FA): Adds an extra layer of verification.
• Activity Logs: Monitor who accessed the intercom and when.
• Auto Revoke: Temporary users should be automatically removed after expiry.
• Encrypted Communication: Ensure all audio/video streams and commands are encrypted.

Common Threats:

Threat	Preventive Measure
Unauthorized access	Enable 2FA and assign strong passwords
Forgotten shared users	Regularly audit access list
Data interception	Use intercoms with encrypted data channels
Physical tampering	Install tamper alerts and secure mounting

Always choose intercom systems from reputable OEM manufacturers like FARHD, which comply with ISO 9001, CE, ROHS, and FCC standards. Their products are built with security-first architecture, making them ideal for sensitive use cases like hospitals, schools, and high-end residential complexes.

To ensure smooth and secure operation of your intercom system, it’s important to implement access management best practices.

For Personal Use:

• Revoke access for guests after use
• Regularly update app passwords
• Use biometric login if available

For Businesses and Apartment Complexes:

• Define user roles clearly (Admin, Viewer, Controller)
• Schedule regular audits of access logs
• Automate onboarding/offboarding of users
• Integrate intercom with access control systems and elevator control

Best Practice	Purpose
User Role Segmentation	Prevent unauthorized actions by employees
Access Expiry Dates	Ensure temporary access doesn’t become permanent
