Using video analytics, other than a data compression process, pre-processing of the video data is performed at the source end to reduce the bandwidth requirement for transmitting the video data to below a bandwidth limit of a Wide Area Network (WAN) over which the video data is to be transmitted. The pre-processed video data is transmitted to a central server via the WAN, where other video analytics processing of the pre-processed video data is performed. Based on a result of the other video analytics processing, a signal is generated for performing a predetermined action, in response to an occurrence of the event of interest at the source end. ## Claims ### Claim 1 A method comprising: receiving video data at a source end, the video data including video data relating to an event of interest captured using a video camera disposed at the source end; pre-processing the video data comprising performing first video analytics on the video data using a first processor disposed at the source end, the first video analytics for detecting the event of interest in a portion of the video data; in dependence upon detecting the event of interest in the portion of the video data, transmitting pre-processed video data comprising the portion of the video data, via a Wide Area Network (WAN), from the source end to a second processor connected to the WAN; transmitting with the portion of the video data at least a pre-processing result other than the pre-processed video data itself; using the second processor, interpreting the pre-processing result and selecting second video analytics processing based on a result of the interpreting; and performing the second video analytics processing on the portion of the video data, the second video analytics for determining predetermined information relating to the event of interest. ### Claim 2 (depends on 1) A method according to claim 1, wherein transmitting the at least a pre-processing result comprises inserting metadata into the transmission of the portion of the video data. ### Claim 3 (depends on 2) A method according to claim 2, wherein the metadata is descriptive of a type of the event of interest detected during the pre-processing. ### Claim 4 (depends on 2) A method according to claim 2, wherein the metadata specifies a particular video analytics engine to be used to perform additional video analytics processing of the pre-processed video data. ### Claim 5 (depends on 1) A method according to claim 1, wherein the second video analytics processing selected by the second processor is fee-per-use-based or subscription based. ### Claim 6 (depends on 1) A method according to claim 1, wherein a bandwidth requirement for transmitting the portion of the video data is less than a bandwidth requirement for transmitting the received video data absent pre-processing thereof. ### Claim 7 (depends on 1) A method according to claim 1, comprising providing a real-time indication of the results of the second video analytics processing. ### Claim 8 (depends on 1) A method according to claim 1, comprising providing the results of the second video analytics processing to another video analytics engine. ### Claim 9 (depends on 1) A method according to claim 1, comprising generating a signal for performing a predetermined action in response to the second video analytics determining the predetermined information relating to the event of interest. ### Claim 10 (depends on 9) A method according to claim 9, wherein the signal is for generating an alert. ### Claim 11 (depends on 10) A method according to claim 10, wherein the alert is a human intelligible alert provided to an indicated user. ### Claim 12 (depends on 9) A method according to claim 9, wherein the alert is provided via a wireless communications channel to a portable electronic device associated with the indicated user. ### Claim 13 (depends on 9) A method according to claim 9, wherein the signal is for forwarding at least a portion of the video data for review by a human operator. ### Claim 14 (depends on 9) A method according to claim 9, wherein the signal is for storing at least a portion of the video data. ### Claim 15 (depends on 9) A method according to claim 9, wherein the signal is for providing at least a portion of the video data to another video analytics engine for further processing. ### Claim 16 (depends on 9) A method according to claim 9, wherein the signal is for billing for usage of a fee-based video analytics engine.
