Frage: How can I enable telnet access?
Antwort: On some devices you can use this URL: http://DEVICE IP:HTTP port/cgi-bin/configManager.cgi?action=setConfig&Telnet.Enable=true . You will need a valid username and password for this operation to succeed.
If you have forgotten your password, you can use our DVR / NVR password recovery service.
We do not recommend to keep your telnet service enabled, as your device and your private video surveillance system will become a target for hackers.
