Abstract

A method for performing video analytics includes receiving at a source end video data including first video data relating to an event of interest. 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.

Claims16

Dependent claims

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.
