1. A surveillance system, comprising:
- an unattended sensor includingan event module that receives an event detection signal that indicates an event external to the surveillance system;
a power control module that selectively operates a data recording device at least partially concurrent with said event based on said event detection signal;
a selection module that selects a portion of data recorded by said data recording device based on content of said data; and
a data transmission module that transmits said portion of data over a wireless radio link;
a channel access mechanism operable to negotiate access to the radio link in accordance with an access protocol;
an encryption module interposed between the event module and the channel access mechanism and operable to encrypt said portion of data received from the selection module before negotiating access to the radio link; and
a remote command node configured to receive said portion of data via the radio link from the unattended sensor and transmit a request for the data recorded by said data recording device to the unattended sensor, wherein the selection module cooperatively operates with the data transmission module to send the data recorded by said data recording device via the radio link to the remote command node in response to the request for the data.

Abstract
A surveillance system includes an event module that receives an event detection signal that indicates an event external to the surveillance system. The system also includes a power control module that selectively operates a data recording device at least partially concurrent with the event based on the event detection signal. The system also includes a selection module that selects a portion of data recorded by the data recording device based on content of the data. A data transmission module transmits the portion over a remote communication link.

13. A surveillance system, comprising:
-
a data recording device that digitally records at least one of video and audio data; a control module that comprises a detection module that receives an event detection signal that indicates an event external to the surveillance system, a power control module that selectively switches said data recording device into an active mode from at least one of a low-power mode and an off mode based on said event detection signal, and a selection module that selects a portion of said one of video and audio data based on at least one of detection of motion within said video data, detection of an object within said video data, detection of sound modulation in said audio data, and detection of a specific sound in said audio data; and a data transmission module that transmits said portion over a wireless radio link, a channel access mechanism operable to negotiate access to the radio link in accordance with an access protocol; an encryption module interposed between the selection module and the channel access mechanism and operable to encrypt and decrypt data sent over the radio link;
wherein the selection module is further configured to receive a request over the radio link for data recorded by the digital recording device and cooperatively operates with the data transmission module to send the recorded data over the radio link in response to the request for the data. - View Dependent Claims (14, 15)

16. A method for providing data within a surveillance system, comprising:
-
receiving an event detection signal that indicates an event external to the surveillance system; selectively switching a data recording device into an active mode from at least one of a low-power mode and an off mode based on said event detection signal; digitally recording at least one of video and audio data; selecting a portion of said one of video and audio data based on at least one of detection of motion within said video data, detection of an object within said video data, detection of sound modulation in said audio data, and detection of a specific sound in said audio data; negotiating access to a wireless radio link in accordance with an access protocol; encrypting said portion of data prior to negotiating access to the wireless radio link; transmitting encrypted portion of data over the radio link; receiving a request at the data recording device for said one of video and audio data based upon a users review of said portion; and transmitting said one of video and audio data from the data recording device over the radio link in response to the request.
