Videalert Frequency Analysis (VFA)
VFA is a system that analyses CCTV images in real-time and counts people or vehicles as they move in and out of pre-specified areas. The unique aspect of the system is that it does not rely on directional consistency in order to count accurately, i.e. it can be used where there are no designated ‘in’ and ‘out’ areas etc. It is inherently far more accurate and reliable than the manual use of tally counters for counting footfall and vehicles.
VFA’s method of counting is becoming critically important to organisations like stadia, media centres, clubs, theatres and museums, as if the number of visitors to a location exceeds a licensed limit, there may well be a breach of health and safety rules, with serious consequences in legal terms. The ability to alert when a limit is being approached is also very valuable to an organisation, as it will allow time for procedures like manning of entrances and doorways to be implemented, prior to limits being breached.
Institutions that receive external funding also need to provide independently verified visitor counts, as grants and funding are now being driven by these statistics and a man with a clicker is not good enough.
Key Features
- VFA is very easy to setup
- The system learns the footfall/traffic to be counted quickly
- VFA produces reports which show visitors by hour, day, week, month and year and also has a live display of visitor numbers
- Traffic statistics can be exported into standardised file types like Excel spreadsheets, so that users can do further analysis beyond the standard reports provided by VFA
- Queuing bottlenecks can be detected, identifying the causes of traffic not being as expected at key time periods
- VFA can be used in conjunction with other Videalert products like VTC and VTM, such that the build-up of queues at turnstiles and retail outlets can be identified quickly and corrective action like directing visitors to locations without queues can significantly improve customer satisfaction
