U-乐队340M-550MHz远距离录像监测系统

Product model: SG-FB99This system introduced Germanic high mixers and chips, and adopt down cinversion technology with a unique modulation. SG- FB99 has strong ability of anti-interference,diffraction and penetration, small size, good for hiding, very suited for basements, mines, caves, mountains and other environments with obstacles. (1) The transmitter used a common video interface, which can connect to an ordinary analogic camera and digital video camera, you can also connect to the head mounted camera or night-vision camera, infrared camera,thermal Imager,etc;(2) Water-proof, AC 220V(can be ordered 12-24V for solar power interface), adopted different cores in order to distinguish from other interfaces, prevent from destroying the equipment by accident. (3) Using with 24dBi directional antennas. Transmit 35-50 km in the general urban environment, 80 km on sea-level. Power supply voltage: (AC 220V 5A), (DC 12V 7.8A), provide standard switch DC 12V 25A, or powered by batteries, but it must have enough current more than 8A.RF indicator Frequency: 340MHz (U-Band) Frequency stability: 0.0005%( Standard) Modulation: F.M.

Such as appearance injury, High-voltage fuse, Damp, Broken seals, soaking,and so on. (PS: The fees of replacement, repairment, etc. all paid by the buyer!!!)Warnings: Make sure the current is switched off before you install the antennas. Otherwise, the transmitter will be destroyed! And do not touch the antenna while it is working!
