Your Fermax Intercom Shows the Wrong Timestamp? Here's How to Fix It
Incorrect timestamps on your Fermax intercom can render recordings unreliable for evidence or system logs. This issue often stems from misconfigured NTP settings, disabled automatic time sync, or incorrect timezone configurations. Follow the steps below to restore accurate timekeeping and ensure your system functions as intended.
Quick Fixes for Fermax Intercom Time Sync Issues
These 30-second checks address the most common causes without requiring configuration changes:
- Power cycle the intercom: For Fermax Meet Panel models, press and hold the reset button on the rear PCB for 15 seconds until the LED flashes rapidly. For Fermax Skyline models, press the reset button inside the panel housing for 10 seconds until an audible tone confirms the reset.
- Check the power LED indicator: A solid green LED indicates stable power. If blinking or off, inspect the ethernet/PoE cable for looseness or damage. For hardwired models, verify the 12V DC adapter is properly connected.
- Test a call from the Fermax MEET ME app: Open the app, select your intercom, and initiate a call. If the timestamp appears correct during the call, the issue may be app-specific. Restart the app and check again.
- Verify the door station screen is responsive: Tap the screen to ensure it reacts to input. A frozen display may indicate a software glitch requiring a reset.
- Confirm the ethernet/PoE cable is firmly seated: For PoE models, ensure the cable is fully inserted into the switch port. For hardwired models, tighten any loose connections at the back of the device.
Step-by-Step Troubleshooting for Fermax Intercom Time Sync Issues
1. Verify NTP Server Configuration
Incorrect NTP settings are a frequent cause of timestamp errors. Access your Fermax intercom's web interface by entering its IP address into a browser. Navigate to System Settings → Time & Date. Ensure NTP Server is enabled and set to a public server like 'pool.ntp.org'. If custom settings are required, confirm the NTP Server Address matches your network provider's configuration. Save changes and wait 5 minutes for the device to synchronise.
2. Check Daylight Saving Time Auto-Adjustment
Manually disabling DST can cause timestamps to drift by an hour. In the Time & Date section of the web interface, ensure Daylight Saving Time is set to 'Auto-adjust'. If manually configured, verify the Time Zone matches your location (e.g. 'Europe/London' for UK users). Save changes and test timestamp accuracy after 5 minutes.
3. Confirm Time Zone and Manual Correction
If automatic time sync fails, manually correct the time. In the Time & Date section, set the Time Zone to your location and adjust the Time Offset if necessary (e.g. +0 for UK). For Fermax Meet Panel models, ensure the Time Format is set to '24-hour' to avoid confusion.
4. Check SIP Registration and Call Routing
Incorrect SIP settings can disrupt time sync through network misconfigurations. Open the Fermax MEET ME app, select your intercom, and check the Device Health tab. If SIP Registration shows 'Unregistered', access the web interface at the device's IP address and navigate to Services → SIP. Verify the SIP Registrar, Proxy Server, and Authentication Credentials match your network provider's settings. Save changes and restart the intercom.
5. Review PoE Power Budget and Wiring
PoE power issues can cause intermittent resets, leading to timestamp errors. For Fermax Meet Panel models, access the web interface and go to Network → PoE Settings. Confirm the PoE Class matches your switch's capabilities (Class 2 or 3 for most Fermax models). Ensure the Power Budget on the switch is sufficient (minimum 12W for most models). For hardwired models, verify the 12V DC adapter output matches the device's requirements (usually 12V/1.5A).

Factory Reset Procedures for Fermax Models
If basic steps fail, perform a factory reset:
- Fermax Meet Panel: Press and hold the reset button on the rear PCB for 15 seconds until the LED flashes rapidly. Reconfigure the device via the web interface.
- Fermax Skyline: Press the reset button inside the panel housing for 10 seconds until an audible tone confirms the reset.
- Fermax VEO-XL Monitor: Press and hold the door release button and settings button simultaneously for 8 seconds until the screen displays a reset confirmation prompt.
Analyse SIP Server Logs and Packet Capture
For persistent issues, access your network's SIP server logs to identify registration failures or timeouts. Use packet capture tools (e.g. Wireshark) to inspect SIP messages for errors. Ensure the intercom's SIP Port (typically ) is open on your firewall or router.
NAT Traversal Troubleshooting
If remote access fails, configure NAT Traversal in the web interface (navigate to Network → NAT Settings). Ensure STUN Server and ICE Candidates are enabled. For complex networks, consult Fermax support at https://soporte.fermax.com.
Root Causes of Fermax Intercom Timestamp Errors
Common causes include:
- Misconfigured NTP settings or disabled automatic time sync.
- Incorrect timezone or DST auto-adjustment settings.
- PoE power budget exhaustion causing intermittent resets.
- SIP registration failures disrupting network communication.
- UK-specific challenges like outdated building wiring or single-band Wi-Fi.
Prevention and Long-Term Care for Fermax Intercoms
To avoid recurrence:
- Schedule periodic firmware updates via the Fermax MEET ME app.
- Monitor PoE switch health and ensure sufficient power budget for all connected devices.
- Use surveillance-rated microSD cards for local storage (e.g. Samsung PRO Endurance) to prevent card degradation.
- Weatherproof outdoor units and inspect cable connections regularly.

When to Replace Your Fermax Intercom
If troubleshooting exceeds 30 minutes and basic steps (restart/reset/reconnect) fail, hardware failure is likely. Check for physical damage, corrosion, or outdated components. Under the UK's Consumer Rights Act 2015, you have up to 6 years to claim faulty goods (5 years in Scotland). Contact Fermax support or a certified installer for further assistance.
