Telnet into DVRs?
A reader writes in asking about various ways to connect to network enabled DVRs. Often times, the manufacturer provides software to connect a Windows PC to the DVR through TCP/IP, but the files that come out are transcoded ... leaving no way to get to the proprietary data.
One of the more popular low-end DVRs is Q-See. They are available all over the place on-line from $200.
I friend of mine has found a way into some Q-See models using Telnet (root/123456) go get to the DVR (on a port other than 80). The files that were transfered were encoded using Q-See's proprietary h.264 codec. He couldn't get them to play on anything - but he had them secured none-the-less.
(If you are reading this and you have a networked Q-See DVR on your network, you should think about changing that password)
