This paper describes the ongoing development of the TERRA(TM) (Timeline Editing for Real-time Review and Analysis) application by Waterfall Solutions Ltd. (WS), which is a high-throughput video analytics tool designed to be highly flexible to user requirements. One of the known pitfalls associated with video analytics is the lack of sufficient user interaction within existing systems, often leading to system unreliability due to an unacceptably high level of false alarms. Therefore, instead of aiming to produce a fully automated system, TERRA(TM) emphasises the importance of having a human user in the loop, and consequently concentrates on providing information in the most intuitive and efficient a manner possible.
