Hikvision's Megapixel Solution Working on Brazil's Railroad

As a reflection of the industry trend, Hikvision continues to develop products demanded by the customer and continues their further expansion into this IP surveillance segment of the market.

It is in the metropolitan region of what Brazilians simply refer to as Rio that a groundbreaking surveillance system was developed for the urban passenger rail network. This rail network, on average carrying 450,000 passengers a day, represents Brazil’s first-ever megapixel surveillance railroad project.

One Camera, Two Uses
As noted, this Brazilian megapixel solution represented a landmark first; yet for VMI Sistemas de Seguranca, it was also a business landmark: this was a tangible opportunity to distance themselves from other distributers/ integrators that do not use megapixel technology in solutions of this nature.

One such component that added this dual value was one of Hikvision’s Megapixel Network Camera. This camera was vital for issues such as recognizing individuals, as well as clear, defined images of fast-moving trains. Mr. Souza elaborated: “Quality — this camera embodies the term. Since this camera needed to be used in two distinct locations; and since both of these locations have fundamental differences, we needed something that possessed both quality and the technical ability to achieve these concurrent goals.”

Additionally, PoE capabilities were used to simplify the installation and power of these platform — adjacent cameras. In both cases whether over the rails or over the platforms, the environment is outdoors. Hikvision’s Outdoor Camera Housing was selected to protect these units against any corrupting conditions they might encounter.

Indoor Camera
Around the actual train terminals themselves, a different Hikvision camera was chosen for optimal surveillance. Due to the placement of this camera — which ranged from on top of the ceilings to inside terminal corridors — it was important to address any potential distance issues that might adversely affect the performance of an indoor camera. In this particular case, compact design brought a less visible presence, thereby reducing the possibility of vandalism — either accidental or malicious.

Additionally, adding to the potent visible deterrent a security camera provides the general public, the 1/3” progressive scan CMOS”provides the ability to view the thousands of everyday passengers running to catch their trains and always in a clear and accurate fashion. 3-axis adjustment allows security personnel all the tools they need to keep an accurate eye on the quickly-changing internal environment of these stations.

In 2011, with Hikvision’s technical know-how, VMI Sistemas de Seguranca and Interimagen were able to secure 5 full stations of this Rio de Janeiro metro line. 2012 promises 10 more stations being secured with this same solution. As such, Brazilian passengers can ride easy knowing that wherever they go — in the station, on the platform, or in the cars, they are being taken care of.
