BlueIris camera software has added some new DDE commands....schedule= profile= ptzpreset=
This used with AHP to execute .bat files you can do many neat things for your IP cameras or any camera supported with BlueIris software.
For example: I have different profiles for nightmode and daymode....which have different motion sensing settings. Also say if motion is detected on one camera...you can make another PTZ camera move to that area and start recording....the possiblities are limited only to your imagination.
Here is a thread about the new commands.
