Aiphone Door Station Showing Wrong Timestamp? Effective Fixes You Can Try
Incorrect timestamps on your Aiphone door station can render recordings unreliable for security or legal purposes. This issue often stems from misconfigured NTP settings, disabled automatic time sync, or firmware incompatibilities. Fortunately, most problems can be resolved by verifying network time settings, checking for firmware updates, and ensuring correct power delivery. Follow the steps below to restore accurate time synchronization.
Quick Fixes for Aiphone Door Station Timestamp Issues
These are 30-second checks to address the most common causes without configuration changes:
- Power cycle the door station: Unplug the power adapter or disconnect the PoE cable for 30 seconds, then reconnect. For IX-DV models, use the factory reset button on the rear (10 seconds hold). For IXG-2C7, hold the reset button on the monitor for 15 seconds.
- Check the power LED indicator: A solid green LED indicates stable power. A flickering or amber light may signal a power budget issue or unstable network connection.
- Test a call from the AIPHONE IXG App: Open the app, initiate a call from the door station, and check if the timestamp appears correctly on the indoor monitor. If the timestamp is wrong during the call, the issue may be with the device's time sync.
- Verify the door station screen is responsive: Touch the screen to ensure it's not frozen. If unresponsive, the device may be in a low-power state due to insufficient PoE power or a failed firmware update.
- Check the Ethernet/PoE cable is firmly seated: For IX-DV and IXG models, inspect the cable connection at both the door station and the switch. Loose cables can cause intermittent power delivery and disrupt time sync.
Step-by-Step Troubleshooting for Aiphone Door Stations
Verify NTP Server Configuration in Web Interface
Access the Aiphone door station's web interface by entering its IP address into a browser. Navigate to System Settings → Network → Time Configuration. Ensure the NTP Server field is set to a public server (e.g. 'pool.ntp.org'). If the Manual Time option is enabled, disable it to allow automatic sync. For IXG models, check the Daylight Saving Time setting — it must be set to 'Auto' to adjust for time zone changes.
Is your door station PoE-powered or separately powered?
- PoE-powered → Check your switch's PoE budget — the port must deliver at least the wattage your model requires (IX-DV: 12W, IXG-2C7: 15W).
- Separately powered → Verify the 12V DC adapter output matches the door station's power requirements (typically 12V/1A).
Check SIP Registration and Time Sync Settings
Navigate to Services → SIP in the web interface. Confirm the Registration Status shows 'Registered'. If not, verify the SIP Registrar Address and Proxy Server fields match your SIP server's settings. For IXG-2C7 models, check the Authentication Credentials section to ensure the Username and Password fields are correct. If the device is unregistered, restart the intercom and re-enter SIP details.
Inspect Door Release Relay Configuration
Access the System Settings → Door Release menu. Verify the Relay Trigger Duration is set to '500ms' (default). Ensure the Relay Wiring (NO/NC/COM) matches your hardware setup. If the relay is wired to a third-party control panel, check the Input Signal Type (dry contact or voltage). Test the relay manually via the web interface by clicking Test Relay Output. If the relay activates unexpectedly, disable it temporarily to rule out interference with time sync processes.
Confirm Call Forwarding and VLAN Settings
For multi-tenant systems (IXG-2C7), navigate to Call Management → Call Forwarding and verify the Ring Group Configuration includes all indoor monitors and mobile apps. Ensure the VLAN ID in Network → VLAN Settings matches the switch port configuration. Incorrect VLAN settings can prevent the device from receiving time sync updates from the network.
Analyze PoE Power Budget and Switch Configuration
For IX-DV and IXG models, access the System Settings → Power menu. Verify the PoE Class setting (should be 'Class 3' or 'Class 4'). Ensure your PoE switch supports at least 12W per port. If multiple devices are on the same switch, check the Total Power Budget in the switch's management interface. For IXG-2C7 models, confirm the PoE Negotiation setting is enabled. If the power budget is exceeded, the device may enter a low-power state, disrupting time sync.
Advanced Diagnostics for Persistent Aiphone Timestamp Issues
Factory Reset Procedures for Specific Models
If basic steps fail, perform a factory reset:
- IX-DV Door Station: Press and hold the factory reset button on the rear for 10 seconds until the status LED flashes rapidly. Reconfigure SIP and time settings after reset.
- IXG-2C7 Master Station: Press and hold the reset button on the back of the monitor for 15 seconds until the screen displays reset confirmation. Reconfigure all settings post-reset.
- JO-1MD Monitor: No network reset is required — use the dedicated 4-wire cabling and reconfigure via the JO Series Configuration Tool (available on Aiphone's support portal).
Analyze SIP Server Logs and Packet Captures
Use the IXG Support Tool (available via Aiphone's support portal) to capture SIP logs and analyze for registration failures or NTP timeouts. For advanced users, use Wireshark to capture packets on the network and inspect NTP traffic. Look for NTP response codes (e.g. '0x11' for unreachable server) or SIP 401 Unauthorized errors indicating incorrect credentials.
Troubleshoot NAT Traversal for Remote Access
If remote access is required, navigate to Network → NAT Traversal in the web interface. Ensure STUN Server and ICE Candidates are enabled. For UK users, confirm your ISP router does not create a double NAT (common with Virgin Media Hub 5x models). If double NAT is detected, configure the router to disable NAT on the PoE switch's port or use a port-forwarding rule to map SIP traffic (port ) and NTP traffic (port 123) to the door station's IP.
When to Contact Manufacturer Support
If timestamp issues persist after all steps, visit Aiphone's official support portal (https://www.aiphone.com/support) and submit a support ticket with:
- SIP server logs (from IXG Support Tool)
- NTP configuration details
- Firmware version (check System Info → Firmware)
- Photos of the door station's power and network connections
Understanding Root Causes of Aiphone Timestamp Errors
Incorrect timestamps on Aiphone door stations often result from:
- SIP server misconfigurations: Incorrect registrar or proxy settings prevent time sync updates from reaching the device.
- PoE power budget exhaustion: Insufficient power delivery (common in multi-device installations) causes the device to enter a low-power state, disrupting time sync.
- Audio/video codec mismatches: Incompatible codecs between the door station and receiving endpoints (e.g. H.264 vs. MJPEG) can interfere with time-stamped metadata.
- NAT traversal failures: Double NAT or CGNAT (common with mobile broadband) blocks NTP traffic, leading to outdated timestamps.
- UK-specific challenges: Older building wiring (non-PoE) or outdoor exposure can degrade signal integrity, affecting time sync reliability.
Prevention and Long-Term Maintenance for Aiphone Systems
To prevent future timestamp issues, follow these best practices:
- Schedule firmware updates monthly via the AIPHONE IXG App or IX Supervision Tool.
- Renew SIP server certificates annually to avoid authentication failures.
- Monitor PoE switch health using the PoE power budget feature in your switch's management interface.
- Weatherproof outdoor door stations with silicone sealant and replace degraded cabling annually.
- Use high-endurance microSD cards (Samsung PRO Endurance or SanDisk High Endurance) for NTP logs and recordings.

Replacement Decisions and Device Lifespan Guidance
Aiphone door stations typically last 5-8 years with proper maintenance. Signs your device may need replacement include:
- Persistent timestamp errors after all troubleshooting steps
- Firmware EOL notices in the System Info menu
- Physical damage to the door station housing or wiring
- Battery degradation in wireless models (3-5 years typical)
Under the UK Consumer Rights Act 2015, you have up to 6 years to claim faulty goods (5 years in Scotland). If your device is under warranty, contact the retailer for replacement. For non-warranty cases, consider upgrading to newer models like the IXG-2C7 or JO-1MD for improved reliability.
