You have detailed control of the threshold levels and can set limits for any of the sensors. For example, you can set the temperature sensor to send an alert if it drops below 40 degrees or goes above 80 degrees. The alerts can be sent to a pager, email or as an onscreen warning.
The onscreen warnings are pop-up windows, accompanied by a very annoying sound that is sure to capture the attention of anyone in front of the screen. Here we are looking at the Bump Alert, which is useful for tracking if anyone is trying to break into your room or server closet.
