The security scenarios are grouped by room. Whenever you enter a room with the mobile orbiter, or choose a room with a regular orbiter, you will see a button for each of the security scenarios you created for that room. Security scenarios are used to operate security camera and alarm controls.
Add New Quad View Security Scenario
To add a new quad view security scenario, click the 'Add new quad view security scenario' button next to the room you want the security scenario to appear in. You will have the option of selecting up to four different camera to view when a security event is triggered. Adding this scenario to each room will give the orbiter in those rooms the ability to view this new security scenario.
If you want this scenario to do something besides just control security devices, like maybe turn on some music too, then first use this wizard page to specify the settings, and then click "Advanced" to go to the Advanced Scenario editor. That advanced page is a bit more complicated, but it allows to add any command to the scenario--not just security control.
