Anything that moves is exhibiting behaviour, and most behaviours are predictable, regular and expected. This can apply as much to a person going about their business as it can to a vehicle, a roulette wheel or a queue of customers in a bank.
Some behaviours are very subtle and in these situations there is no substitute for the trained eye of an experienced CCTV operator. However many behaviours are entirely mundane and easily analysed; it is these scenarios where intelligent analytics can prove to be the most effective, providing vigilance 24 hours per day at a fraction of the cost of additional control room staff.
Behaviours such as approaching a secure perimeter or loitering in a car park are ideal candidates for automation, but this approach goes far beyond human behaviour. The behaviour of a roulette wheel or a vehicle is equally predictable and anomalies can be identified instantly and appropriate action taken.
In many instances, such as analysing the way that people behave when they enter the lobby of a bank or identifying congestion build-up on the highways, it would be impossible to gather this information cost effectively without automating the process.
