Hikvision IP cam: where's the save button??

[jrmymllr 0]

I just got some DS-2CD2332-I cameras and am on Advanced Configuration/Image/Display Settings screen, and am trying to change the Day/Night Switch settings. Where's the save button? This is crazy. The other tabs have it. I change the Sensitivity and it won't stay, because there's no save! There's some good screenshots on this webpage:

Go down to where this text is: "HOT TIP: For better Infra Red results at night turn Smart IR on. To do this go to the Image Section, Day/Night Switch and change Smart IR to ON". It's the screenshot right below that.

 

If I change Switch Day and Ni.... to scheduled, it will say "Saved" at the bottom, but I want auto switch and I want to change the Sensitivity.

 

What am I missing that's obvious?

 

EDIT: I got it. I needed to install "webcomponents.exe" from the camera and use IE.
