Upgrade Video Encoder with the Latest Firmware

Run IPCManager if you already installed it
Enter username and password
Go to Firmware Upgrading-->Add Online IPC
Select the encoder and Browse the latest firmware
Click "Upgrade" and it will start upgrading immediately
Check "Upgrading Status" whether it's upgraded successfully
Go back to "IPC Searching" and click "Refresh" to check whether it's upgraded to the latest version

NOTE: It's strongly recommended to upgrade it via IPCManager instead of accessing it from the browser if you're not the professional guys.
