Event surveillance system
First Claim
1. A surveillance system, comprising:
- an event information capturing device;
a random access data store for storing event information captured by the event information capturing device; and
a control processor connected to the event information capturing device and to the random access data store, the control processor responsive to an identification of the occurrence of events of interest, and including a data management functionality for dynamically managing the storage of captured event information in the random access data store by identifying, accessing and deleting from storage certain portions of the event information previously captured by the event information capturing device and stored in the random access data store that is not related to the identified events of interest in order to make room for the storage of subsequently captured event information.

Abstract
A surveillance system operable to capture images and sounds concerning events for storage in a random access data store. A data management functionality is provided to dynamically manage storage of information in the data store and thus emphasize retention in storage of information concerning those events identified as events of interest. No longer wanted information is deleted to make room in storage for subsequently captured information. The identification of an event as being "of interest" is made by a mode control functionality in response to the processing of signals received from an environment sensor monitoring conditions related to the events. The mode control functionality further controls the operation of the imaging and audio device used to capture images and sounds. The captured information is encrypted prior to storage to insure its integrity.

13. A surveillance system, comprising:
-
event sensing means for capturing information concerning events; an environmental sensor for sensing event conditions and outputting sensor signals indicative of event occurrences; a storage device for storing the information captured by the event sensing means; and a control processor connected to the event sensing means, the environmental sensor and to the storage device, the control processor including a mode control functionality for processing the sensor signals to identify the occurrence of an event of interest and, in response thereto, dynamically select a mode of operation for controlling operation of the event sensing means to emphasize the capture of information concerning the event of interest for storage in the storage device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

28. A surveillance system, comprising:
-
a plurality of sensing devices for acquiring event information; a storage device for storing acquired event information; and processing means connected to the sensing devices and the storage device including means responsive to the detection of an event of interest for controlling the operation of the sensing devices to acquire information concerning the event of interest and means for managing the storage and subsequent deletion of acquired event information to emphasize the retention in the storage device of event information concerning the detected event of interest. - View Dependent Claims (29, 30, 31, 32, 33)

34. In a surveillance system operating to acquire frames of event information, a method for managing the storage of the acquired frames of event information in a random access data storage device having a plurality of storage addresses, comprising the steps of:
-
initially storing all frames of acquired event information at addresses in the random access data store; monitoring for the detection of an event of interest; accessing the addresses of those frames of previously acquired and stored event information not relevant to the detected event of interest; and deleting the accessed frames of event information from storage making the accessed addresses available for the storage of subsequently acquired frames of event information. - View Dependent Claims (35, 36, 37, 38)
