I bought these just a few months ago, and it's not only this DCS-932l that doesn't do https, but the DCS-930L doesn't either. I bought the DCS-930l (I actually thought I was getting 2x DCS-932L's as I grabbed that and the one behind it) at the same time, and these two were all they had...
Https has been around for how long? We have been required to send plain-text passwords until recently?
https should have been the default years ago.
