A video analysis, indexing and retrieval system for connecting to a surveillance camera multiplexer. Designed to run on a mid-range PC (in 2001 - a 500MHz Athlon), Warden provided the following features: - Demultiplexing of 16 camera streams
- Motion graphing for easier searching
- Motion thresholding to save space
- Rotating buffers so periods leading up to "interesting" events are guaranteed to be saved
- 2 months of recording on the internal 80GB HDD
- Java front-end for quickly finding periods of interest in the video stream
Despite being written in 2001, the system was still in use as recently as 2004 (and might still be - I've not been back since!). During that time it has helped to resolve several security incidents without needing an officer to wade through hours of tape.
