7.3.3  Firmware Update 
Firmware updates are available at us.zyxel.com/support. After downloading the latest 
firmware for your camera, click the [Browse] button to locate the firmware file on your 
hard drive, then click the [Upgrade] button to update the camera’s firmware. Once the 
upgrade process begins, it must not be interrupted or you risk permanently damaging 
your camera. 
If some icons are out of place after reboot, press [Ctrl] + [F5] to force your browser to 
refresh its cache. 
Caution: 
Before updating firmware, close all other browser windows and 
background applications. 
Note: Should you accidentally close your browser’s window during the 
upgrade process, DO NOT unplug the power cable or reset the camera 
immediately. Try waiting 3-5 minutes, as the camera may complete the 
upgrade process on its own.
