Infinova announced since 2005, basically all of the 1,500 miles (2,500 km) of expressways in service within China's Shaanxi province are using Infinova products for security surveillance. This includes more than 2,000 cameras, 100 video matrix switching systems and fiber optic modems. For intelligent, safe and efficient highways, China is leading the way.
"Effective highway video surveillance alerts authorities as congestion starts to develop and helps them deploy highway patrols to manage traffic flow and reduce delays," said Mark Wilson, Infinova VP of Marketing. "When accidents occur, the authorities can assess the situation quickly. Using rapid maneuverability cameras, operators can capture the early stages of a highway incident and provide life-saving information to emergency teams."
According to Wilson, the cameras used are designed for outdoor video surveillance on highways and intelligent transport systems (ITS). Infinova's integrated PTZ system can operate in winds up to 130 mph (200 Kph) and features a 15" (38 cm) housing for its 1/2-inch (1.27 cm) camera and 1/2inch (1.27 cm) motorized zoom lens, giving operators a better, long-range view.
The system is equipped with a compass display so that operators can see in which direction the camera is looking, as well as a privacy masking with 16 programmable zones. Unlimited continuous pan lets operators look straight down and tilt the camera up to look up hills in the highway. Its fast pan and tilt speeds enable operators to move the camera quickly when operators need to view incidents in multiple locations.
The housing is IP66 rated which means it is dust-tight and is equally protected against water ingress, even if a water jet is directed against the enclosure from any direction. The housing is also equipped with a wiper, heater and defroster for extreme conditions.
In an emergency situation, the system's flexibility and rapid maneuverability allow operators to move the camera quickly and point it in any direction. Using these cameras, operators can brief emergency teams as they are traveling to a highway incident, helping them save lives and function with maximum effectiveness when they arrive.
