Our clients are able to make use of what’s known as Black Screen Technology or Black Screen Monitoring with our iSentry integration. Essentially, it removes the need for live viewing of video footage, by only displaying system-flagged events in the control room and as a result, operators are only viewing short flagged events. The rest of the time, the screen is “black.”
The software also tackles the issue of human concentration. According to a Harvard study, CCTV control room monitors are only able to effectively concentrate on TV screen footage for approximately 22 minutes on average.
The iSentry behavioural module only delivers a 9-13 second clip of an “unusual event ” which the operator can then dismiss or escalate. The software sees no detail whatsoever - imagery fed into the system is downscaled and grayscale. iSentry merely analyses groups of pixels and has no concept of what those groups of pixels represent. It ‘sees’ only the interaction of groups of pixels within a specific scene and their interaction with the fixed environment. When a group of pixels behaves in a way that is not consistent with the previous behaviour, it will be flagged as unusual with no further context.
The unusual event that is flagged is then made available in the form of a video clip for operators to then view. Black screen means the operators in a control room are only viewing flagged events, never full video feeds. The cameras and software do the monitoring.
In a nutshell:
“Artificial Intelligence software ‘self-learns’ normal behaviour patterns within 24hrs. Operators can now view a video on an event basis, not a constant stream - in other words, they only watch what matters. Unusual behaviour alerts reduce the video that an operator needs to monitor initially by more than 95%. It also eliminates up to 80% of the remaining video through deep learning. As a result, monitoring companies can scale efficiencies. They are typically able to increase the number of cameras that an operator can monitor up to 100 times.
The iSentry unusual behaviour module is an entirely unsupervised network. There is no ability whatsoever to programme it in any way (eliminating the question of pre-programmed bias) except to make it more or less sensitive to pixel changes.
