Your Fermax Intercom May Have Been Hacked — Here’s What to Do
Your Fermax intercom has likely been compromised by unauthorized access, potentially exposing video feeds or call data. This issue typically arises from weak passwords, outdated firmware, or misconfigured network settings. The solution requires immediate action to secure the device, change credentials, and ensure network security protocols are enforced. Follow the steps below to restore control and prevent future breaches.
Quick Fixes to Try First
These are 30-second checks to address the most common causes without configuration changes:
- Power cycle your Fermax intercom: Unplug the device for 10 seconds, then reconnect it. This resets the system and may resolve temporary glitches.
- Check the power LED indicator: A steady green light indicates normal operation. If the light is blinking or off, verify the power supply is stable.
- Test a call from the Fermax MEET ME app: Open the app, select your intercom, and initiate a call. If no response occurs, the issue may be with the intercom or network connectivity.
- Verify the intercom screen is responsive: Ensure the display is not frozen or unresponsive. Tap the screen to check for touch sensitivity.
- Inspect the Ethernet/PoE cable: Confirm the cable is firmly seated in both the intercom and the switch. A loose connection may cause intermittent issues.
Step 1: Secure Your Fermax Intercom’s Network Settings
Check SIP Registration Status
Log into your Fermax intercom’s web interface using its IP address. Navigate to Services → SIP and verify the SIP Registrar and Proxy Server settings match your network configuration. Ensure the Authentication Username and Password are not default and have been changed to strong, unique credentials. If the Registration Status shows 'Unregistered,' restart the intercom and confirm the SIP server is reachable. For Fermax Meet Panel models, use the Network Diagnostics section in the Fermax MEET ME app to monitor connectivity in real time.
Enable SRTP Encryption
If your intercom is connected to a SIP server, confirm that Secure Real-time Transport Protocol (SRTP) is enabled. This prevents eavesdropping by encrypting audio and video transmissions. Navigate to Advanced Settings → SIP → Encryption and select SRTP as the preferred protocol.
Step 2: Update Firmware and Enable Two-Factor Authentication
Ensure Firmware Is Up to Date
Outdated firmware can introduce vulnerabilities. Access the Fermax support portal and check for available firmware updates for your intercom model. Download the latest version and follow the installation instructions. Firmware updates often include critical security patches and performance improvements.
Enable Two-Factor Authentication (2FA)
To add an extra layer of security, enable 2FA in the Fermax MEET ME app. Open the app, navigate to Settings → Account Security, and activate Two-Factor Authentication. This requires a second verification method (e.g. a code sent to your phone) before granting access to the intercom.
Step 3: Review and Secure Access Logs
Check for Unauthorized Access
Access logs can reveal if your intercom has been compromised. Log into the web interface and navigate to System → Access Logs. Review recent activity for any suspicious entries, such as login attempts from unfamiliar IP addresses or unusual call patterns. If unauthorized access is detected, reset all user credentials and enable 2FA immediately.
Remove Shared Users
If your intercom is shared with other users (e.g. building managers), ensure only trusted individuals have access. Navigate to User Management → Shared Users and remove any accounts that are no longer needed. This minimizes the risk of unauthorized access.
Step 4: Inspect PoE Power Budget and Wiring
Verify PoE Switch Compatibility
Fermax intercoms require a PoE switch that supports at least 802.3af (15.4W) for stable operation. For models like the Fermax Meet Panel or VEO-XL Monitor, ensure the PoE switch provides 12–25W to avoid power negotiation failures. Inspect the Ethernet cable for damage and confirm it is securely connected to both the intercom and the switch.
Check Hardwired Power Supply
For hardwired models like the Fermax Skyline, verify the 12V DC power supply matches the device’s specifications. If the power budget is insufficient, consider upgrading to a higher-wattage PoE switch or using a separate power adapter.
Step 5: Configure Door Release Relay Settings
Verify Relay Wiring
Access the Advanced Settings → Door Release section in the web interface. Ensure the Relay Type (NO/NC) matches your lock’s wiring configuration. For Fermax Meet Panel models, set the Trigger Duration to 1–3 seconds to prevent false activations.
Test the Relay Manually
If using a Fermax VEO-XL Monitor, test the relay manually via the Door Release Test feature in the Fermax MEET ME app. If the relay fails to activate, inspect the wiring for continuity and ensure the door lock is compatible with the intercom’s relay output.
When Basic Fixes Have Not Worked
Perform a Factory Reset
If your intercom remains unresponsive after basic troubleshooting, consider a factory reset. For Fermax Meet Panel models, press and hold the reset button on the rear PCB (accessible after removing the panel from its frame using the security tool) for approximately 15 seconds until the LED indicator flashes rapidly. For Fermax Skyline models, press and hold the reset button inside the panel housing (access via security screws on the faceplate) for 10 seconds until an audible tone confirms the reset.
Analyze SIP Server Logs
If the issue persists, consult your SIP server logs to identify potential misconfigurations. Look for errors related to SIP registrar, proxy settings, or authentication failures. If the logs indicate a problem with your network provider, contact them for further assistance.
Contact Fermax Support
If all troubleshooting steps fail, reach out to Fermax support via their official website. Provide detailed information about the issue, including any error messages, firmware versions, and steps already taken. A certified technician can guide you through advanced diagnostics or recommend hardware replacements if necessary.
Understanding the Root Causes
Common Reasons for Security Breaches
Security breaches on Fermax intercoms are often linked to weak passwords, unsecured SIP configurations, or outdated firmware. Default credentials are a common vulnerability, so it is critical to change them immediately. Additionally, misconfigured SIP settings (e.g. incorrect registrar addresses or proxy configurations) can leave the system exposed to external attacks. Outdated firmware may lack critical security patches, making the intercom susceptible to known exploits.
UK-Specific Challenges
UK-based users may encounter additional challenges, such as weather exposure on outdoor intercoms or older building wiring that may not support modern PoE requirements. Ensure outdoor models are properly weatherproofed and that the network infrastructure meets current standards for reliability and security.
Prevention and Long-Term Care
Maintain Firmware and Security Settings
Schedule regular firmware updates to ensure your Fermax intercom remains secure. Enable SRTP encryption and two-factor authentication in the Fermax MEET ME app to add layers of protection. Monitor access logs periodically to detect any unusual activity.
Weatherproof Outdoor Models
For outdoor intercoms, ensure they are installed in weatherproof enclosures and that the wiring is protected from moisture and corrosion. Regularly inspect the device for signs of water damage or exposure.

When to Consider Replacement
Assessing Intercom Lifespan
Fermax intercoms typically last 5–8 years, depending on usage and maintenance. Signs that replacement may be needed include frequent malfunctions, inability to update firmware, or incompatibility with modern network standards. If troubleshooting exceeds 30 minutes without success, hardware failure may be the root cause.
UK Consumer Rights Context
Under the Consumer Rights Act 2015, UK consumers have up to 6 years to claim faulty goods. If your intercom is still under warranty, contact the manufacturer for a replacement or repair. For non-warranty cases, consider consulting a certified installer for professional assistance.
