BRAZIL: Rio de Janerio metro operator MetrôRio chose IndigoVision and its local partner Setha Prosegur to supply an IP-based video security system incorporating an activity controlled frame rate feature. This reduces data storage requirements by regulating image capture rates according to motion observed.
When there is no activity, video is streamed at minimal frame rate. As soon as movement is detected, the video is transmitted at the maximum configured frame rate, providing greater detail for analysis.
Existing analogue cameras have been integrated into the system using IndigoVision encoders.
