I will describe the steps you need to take to update the firmware of the D-Link DCS-910 camera:
1) Download the new firmware from the official site:
http://ftp.dlink.ru/pub/Multimedia/DCS-910/Firmware/
2) Open the web interface of the camera by typing the address http://192.168.0.1 in the browser (maybe 192.168.1.1) and enter the login / password (standard is admin without a password).
3) In the interface that opens, select “MAINTENANCE” – “Firmware Upgrade”, then click “Browse” and select the previously downloaded firmware file (unpacked from the downloaded archive), then click “Upload” to start the update process.
We are waiting for the completion of the process 2-5 minutes.
Done.
