Hi! Sorry for the delay (I'm not a "regular" here)
Please elaborate on the "Eliminate the emails..." request 
ActiveX is not required for all browsers. Firefox uses Java.

The e-mail .log issue has already been addressed above. I was also able to make them less frequent by increasing the blank-out time between detecting motion events.
On the Java/ActiveX issue: I have three The DCS-942L cameras that use a Java applet for drawing the motion area in the Manual Motion Detection setup screen. It works with any browser that supports Java including Safari and Firefox on Mac OSX.
On the DCS-2230, the Manual Motion Detection Setup seems to use an ActiveX control for choosing the motion area, so it works only with IE on a Windows computer. It does not work with Safari or Firefox. Everything else with the camera works with the Mac except for the motion setup.
