Rio Metro goes IP

by Mark Rowe

An IP video security contract to replace ageing analogue CCTV at MetrôRio, Rio de Janeiro’s metro, was won by UK manufacturer IndigoVision. Newton Werneck, CIO of MetrôRio said: “IndigoVision’s image quality is excellent and the distributed architecture of the system will allow the surveillance network to grow along with the metro system.”

Another factor according to the manufacturer is its products’ storage capability. The company points to its compression technology and the use of the Activity Controlled Framerate (ACF) feature, built into the IP cameras. ACF regulates the frame rate of the video stream according to the motion in a particular scene. When there is no activity, video is streamed at minimal frame rate; once any motion is detected, video is simultaneously transmitted at the maximum configured frame rate. This provides greater detail for analysis and allows for economy of data storage, the makers add.

IndigoVision’s Brazilian partner Setha Prosegur worked with MetrôRio to create the CCTV system, which includes 141 fixed IP cameras, 21 PTZ cameras and about 700 analogue cameras that have been integrated into the system using IndigoVision encoders. An IndigoVision NVR-AS 3000 (network video recorder) is in place at each metro station, with back-up provided between stations.

Founded in 1979 with five stations operating on one line, MetrôRio now covers 47km (29 miles) divided into two lines and 35 stations. The network continues to grow with a further line under construction and due for completion in 2016.
