Utilizing presence information for the purpose of enhanced surveillance

摘要

Surveillance system endpoints communicate with each other to send and receive presence information. The surveillance endpoints may react to the received presence information. For example, if one surveillance camera stops functioning, one or more other cameras can react to the presence information, or lack thereof, sent from the malfunctioning camera. Thus, one or more of the other cameras can cover the area normally covered by the malfunctioning camera. Thus, the surveillance endpoints can automatically react to presence events in a network of surveillance endpoints.

1. A method for adjusting surveillance in a surveillance network comprising three or more surveillance endpoints, the method comprising:
a first surveillance endpoint receiving a plurality of broadcast presence events from a plurality of other surveillance endpoints, wherein one of the plurality of broadcast presence events is from a second surveillance endpoint, wherein the one of the plurality of broadcast presence events is a command to focus on a location of an individual person that the second surveillance endpoint is currently focused on, and wherein the first surveillance endpoint and the second surveillance endpoint are video cameras; in response to receiving the command to focus on the location of the individual person, the first surveillance endpoint automatically determining, based on the location being within a panning range of the first surveillance endpoint, if the first surveillance endpoint can respond to the command to focus on the location of the individual person; and in response to determining that the first surveillance endpoint can respond to the command to focus on the location of the individual person, the first surveillance endpoint automatically performing an action to focus on the location of the individual person.
