Perhaps I'm expecting a bit much but why is the security of this firmware so poor? It's a security camera which should be secure...?
My gripes:
You can't specifically use HTTPS and disable HTTP.
Where is the SSH support? ... Telnet, who uses telnet still, it's 2013 we use encryption now?
I ran a scan against the device and it has several high ports open, not sure why...
Can you change the logon message prompt? It displays: "The Server <YOURHOSTNAME.COM> at DCS-5020L requires a username or password. Anybody can look up the model number and find the default username/password (which you can't disable in the firmware).
