The present invention is directed to providing systems and methods for remotely
monitoring sites to provide real time information which can readily permit distinguishing
false alarms, and which can identify and track the precise location of an alarm.
In embodiments, monitoring capabilities such as intrusion/fire detection and tracking
capabilities, can be implemented through the use of multistate indicators in a
novel interface which permits information to be transmitted using standard network
protocols from a remote site to a monitoring station in real-time. In embodiments,
communications can be handed from the centrally located host monitoring station
to a mobile monitoring station (for example, a laptop computer in a responding
vehicle, such as a police or fire vehicle). Additional embodiments include high,
low, and rate-of-change alarms; chromagraphic representation of the value of an
environmental or other parameter measured in a space; and detection and location
of portable interface devices in a space.
