This is the so-called 'mini-system' recovery mode that is used after a failed or incompatible firmware update. It's a basic Linux kernel with no web server (so no GUI) or applications loaded.
You should be able to get your camera back into a working state as follows:
Download the firmware from here:
http://www.ipcamtalk.com/showthread...are-Downgrader-5-3-0-Chinese-to-5-2-5-English and extract the digicap.dav file.
Place it in the folder where the tftpserve.exe resides.
This
tftp server must be the Hikvision-specific one - it says 'Hikvision tftp server' in the window title. A normal tftp server will not work, it doesn't respond to the Hikvision-specific handshake.
Change your PC IP address to 192.0.0.128, subnet mask 255.255.255.0
Start the tftp server.
Ensure that both the PC and the camera are wired as usual into your LAN router or switch.
Power-cycle the camera and watch the status window of the tftp server for messages. The update can take several minutes.
If successful, shut down the tftp server and power cycle the camera. Find it on SADP and set the IP address as required.
If nothing happens, it's likely that your Windows firewall is blocking access to the tftp server, depending on the answer you gave to the prompts about the firewall when tftpserve.exe was first run.
In Windows firewall 'Advanced settings', check that full access is allowed to UDP and TCP for both private and public networks for tftpserve.exe, modify as required.
