# Camera system time is set to the year 2000.

The incorrect time can cause various issues, such as recording problems, start-up boot problems (emergency system) or any other issues that require the correct time for communication.

MOBOTIX has already provided a firmware update for this issue.

> First, set the camera to the **current time** and then update the camera firmware.

### Camera firmware:

> **[MX-System Release 4.7.3.11-r7 | MOBOTIX AG](https://www.mobotix.com/en/node/20701)**

## From the release notes 4.7.3.11-r7:

### Bug fixes

- **When restarted, the Mx4 and Mx5 camera series were reset to the year 2000.**  
Since 1 January 2026, the Mx4 and Mx5 camera series have been reset to the year 2000 when restarted without an NTP server.

**IMPORTANT - Step-by-step instructions for installing firmware MX‑V4.7.3.11‑r7:**

If the camera is operating with the system date set to **2000** , the firmware update may abort with the message **‘Fatal: Signatures failed. Aborting.’** In this case, the time must be set correctly once before the update. After the update, the camera may revert to **year 2000** again – this is **expected** and will be corrected afterwards.

1. **Set the time and date before the update**

- Open **Admin Menu → Time & Date**.
- Click on ‘ **Set time to local PC time** ’.
- Wait until the setting has been applied.

1. **Update firmware**

- Open **Admin Menu → Update System Software**.
- Select the file **MX\_system\_4\_7311\_r7.mpl**.
- Upload the file and start the update.
- Restart the camera.

1. **Reset the time and date after the update**  
5.\*Note: After restarting, the camera may start up in the year 2000. This is expected behaviour.

- Open **Admin Menu → Time & Date**.
- Click on ‘ **Set time to local PC time** ’ again.

1. **Final restart**

- Open **Admin Menu → Restart**.
- Click on ‘ **Restart Camera** ’.

**RECOMMENDATION: Reset the camera to remove any remaining files from the year 2000:**

- Open the **Admin Menu → Reset to Factory Settings**
- Click on ‘ **Remove Logs** ’ and confirm.
- Check the **settings for the SD card and MxFFS recording**

**If you encounter problems:**

- Format the SD card.
- Delete the MxFFS archive.
- For classic file server recording with directory structure (NFS or CIFS as primary destination), move the old directory to a new location and start a new recording.
