Fix Incorrect Timestamps on Your Comelit Intercom
Incorrect timestamps on your Comelit intercom can render recordings unreliable for evidence or system logs. This issue typically stems from misconfigured network time protocols (NTP), incorrect timezone settings, or firmware that hasn’t synced with the correct time server. By following these steps, you’ll resolve the problem and ensure your device’s clock aligns with the correct time.
Quick Fixes for Comelit Timestamp Errors
Before diving into advanced settings, try these 30-second checks:
- Power cycle the door station: Unplug the device or disconnect the power supply for 10 seconds, then reconnect it. This resets the internal clock and may resolve temporary sync issues.
- Check the power LED indicator: A steady green light indicates proper power. A blinking or unlit LED suggests a power supply issue or a failed firmware update.
- Test a call from the companion app: Use the Comelit App to make a test call. If the timestamp appears correct in the app but not on the door station, the issue may be local to the device.
- Verify the door station screen is responsive: Tap the screen or press buttons to ensure it’s not frozen or unresponsive due to software glitches.
- Check the Ethernet/PoE cable: Ensure the cable is securely connected to both the intercom and the router/switch. A loose connection can disrupt network time sync.
Working Through Your Comelit Issue for Comelit Timestamp Issues
1. Configure NTP Settings via the MyComelit Portal
Log into the MyComelit management portal using your administrator credentials. Navigate to Device Settings > Network > Time & Date. Ensure the NTP Server field is populated with a public time server (e.g. pool.ntp.org). If the field is blank, enter a valid server. Confirm the Time Zone matches your location (e.g. Europe/London for the UK) and that Daylight Saving Time is enabled. Save your changes and wait 5-10 minutes for the clock to sync automatically.
2. Verify Manual Time Settings (if NTP fails)
If your device is set to Manual Time instead of Automatic Sync, this may cause persistent timestamp errors. In the MyComelit portal, go to Time & Date and switch to Automatic Sync. If you must use manual settings (e.g. in a disconnected network), set the Date, Time, and Time Zone manually. Ensure the Daylight Saving toggle is correct for your region.
3. Check for Firmware Updates
Outdated firmware can cause time sync failures. In the MyComelit portal, navigate to System > Update. If an update is available, download and install it. Ensure your device is connected to a stable internet connection during the update process. After updating, restart the intercom and verify the timestamp.
4. Test Relay and Door Lock Functionality
Incorrect timestamps may indicate broader system issues. In the MyComelit portal, go to System > Relays. Select the relay associated with the door lock and press Test Relay. If the relay fails to activate, check the wiring (NO/NC configuration) and ensure the Relay Output is enabled in the settings. A faulty relay can cause the device to behave unpredictably, including timestamp errors.
5. Reset the Device to Factory Defaults (Model-Specific Instructions)
If the issue persists, perform a factory reset. The process varies by model:
- Comelit Icona (PoE/hardwired): Press and hold the reset button on the rear panel using a thin tool for 15 seconds until the LED flashes rapidly.
- Comelit Quadra (hardwired/PoE): Press and hold the reset button on the PCB (inside the panel) for 10 seconds until the status LED flashes.
- Comelit Visto (wireless): Press and hold the pairing button on the back for 10 seconds until the LED flashes rapidly.
After resetting, reconfigure the device via the MyComelit portal, ensuring NTP and time zone settings are correctly applied.
Advanced Diagnostics for Persistent Timestamp Issues
Check SIP Server Logs for Time-Related Errors
If your intercom uses SIP for communication, incorrect timestamps may be linked to SIP server misconfigurations. Log into your SIP provider’s portal and check for error logs related to time sync or authentication failures. Ensure the Registrar Address and Proxy Server in the MyComelit portal match your provider’s settings. If discrepancies exist, update the fields and restart the device.
Perform a Packet Capture for Network Time Issues
For advanced users, use a packet capture tool (e.g. Wireshark) to monitor NTP traffic between your intercom and the time server. Look for NTP packets (port 123) and ensure they’re being received without errors. If packets are dropped or delayed, check your network firewall settings and ensure port 123 is open.

Comelit engineers can guide you through advanced diagnostics or dispatch a technician if hardware failure is suspected.
Understanding the Root Causes of Timestamp Errors
Incorrect timestamps on Comelit intercoms often arise from one of these causes:
- Misconfigured NTP settings: If the NTP Server is incorrect or disabled, the device cannot sync with the correct time.
- Incorrect timezone or daylight saving settings: A mismatch between the device’s timezone and your location can cause timestamps to drift.
- Outdated firmware: Older firmware versions may lack support for modern NTP protocols or contain bugs affecting time sync.
- Network connectivity issues: If the intercom is isolated from the internet or behind a restrictive firewall, it may fail to reach NTP servers.
- UK-specific challenges: Older buildings may have inconsistent power supplies or outdated wiring, affecting PoE stability and, indirectly, time sync.
Preventing Future Timestamp Errors
To avoid recurring timestamp issues, follow these best practices:
- Schedule regular firmware updates via the MyComelit portal to ensure your device remains compatible with NTP protocols.
- Enable automatic time sync and avoid manual settings unless absolutely necessary.
- Monitor PoE switch health using your network administrator tools to prevent power-related disruptions.
- Weatherproof outdoor intercoms to avoid environmental damage that could interfere with internal components.

When to Consider Replacing Your Comelit Intercom
If troubleshooting fails and the timestamp error persists despite factory resets, hardware failure may be the cause. UK consumers have up to 6 years to claim faulty goods under the Consumer Rights Act 2015. Signs that replacement is needed include:
- A device over 8 years old with no available firmware updates.
- Persistent timestamp errors even after factory resets and firmware updates.
- Physical damage to the intercom (e.g. water ingress on outdoor models).
- Inability to sync with NTP servers despite correct configuration.
For replacements, consult your local Comelit dealer or visit the official support site for guidance.
