- 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.
