MONMOUTH JUNCTION,
NJ - December 9, 2009 - Infinova today announced that analog video, fiber and
Ethernet have been combined to create a best-in-class hybrid surveillance solution
for the 222-acre Nanjing Olympic Sports Center, one of China's largest. The
sports complex consists of several best-in-class public sports venues including
a large multipurpose stadium with a capacity of 80,000, an indoor gymnasium
with a capacity of 15,000, an aqua-center with four pools and a tennis center
with 20 professional courts, plus a technical operations center and related
facilities.
Given the diverse
size and location of the complex, system requirements demanded that the solution
be flexible, highly reliable and provide excellent quality video. To achieve
these goals, the integrators opted for analog video from Infinova's PTZ Dome
cameras to be directly viewed and controlled through matrix switchers. By using
direct control, the integrators could guarantee video quality and real-time
PTZ control of the cameras with no noticeable delay between the time operators
move their joystick and the time the camera responds. The system also features
fixed cameras and fiber optic transceivers.
"This
installation shows how Infinova is able to help integrators bring together multiple
technologies to ensure customer project requirements are met affordably,"
affirms Mark S. Wilson, Infinova vice president, marketing. "Even though
the Center chose an analog solution, it did not have to give up the advantages
of IP technology because the Infinova matrix switchers and keyboards use hybrid
technology, being IP-enabled through their Ethernet ports."
By controlling
the distributed network of matrix switchers over Ethernet, system reliability
was significantly enhanced. There is no "master" matrix switch that
can become a single point of failure for operator control. Plus, the video matrix
switchers incorporate advanced video loss detection on each input signal and
issue an alarm if the camera fails or the cable is cut.
Multiple cameras
are installed throughout the complex, controlled by operator keyboards or video
management software. The keyboards can communicate with the matrix switchers
either over the network or via a direct RS-232 connection, providing an additional
level of flexibility.
Since each
sports center is a long distance from the central control room, the designers
selected Infinova fiber optic transceivers to connect all the matrix switchers
together. The fiber provides crystal clear video while the distributed robustness
of Ethernet yields problem free control. An additional advantage is that fiber
optics provides excellent protection against lightning, common in the area.
From a financial point of view, using a single fiber for multiple cameras resulted
in a significant reduction of installation costs versus traditional coax cable.
