Specifications
COFDM modulation and MPEG-2 video compression;PTZ control in NLOS condition;
Ethernet interface for compressed video output
Introduction
This surveillance equipment is developed with passive infrared imaging technology that enables the system to work in both daytime and pitch-black conditions. Especially by adopting the latest technologies of COFDM modulation and MPEG-2 video compression technologies, it can realize high quality of NLOS (non line-of-sight) transmission with stable, real-time and high definition images. The system is of low power consumption and the double-lens camera that has complementary working modes enables the system to work continuously. In the receiving center we equip a portable multifunctional receiver that can record the real-time video by USB interface and control the PTZ in NLOS (non line-of-sight) condition. Since it is easy to be installed everywhere, this system has been widely used in many fields such as Battlefield Scouting, Frontier Defense, Airport Inspection, Oil Field Guarding, Coast Patrolling, Prison Monitoring, Safe-care Region Guarding and Hunting etc.
