Compact lightweight UHF 30km 400mw COFDM wireless transmitter for moving transmission
System Introduction
ST6200TPS-SD COFDM mini transmitter is a new concept in remote surveillance, designed specially to meet the special requirements of covert missions. The equipment is highly integrated and can realize wireless video transmission in mobile and NLOS (Non line-of-sight) conditions. With professional clothes and pinhole camera, it can be used in public security bureau or security department to finish covert missions. The transmission range can be up to 30km in LOS (line-of-sight) condition.
Transmitter Features
COFDM modulation, stable transmission
Transmission security by encryption of AES128 bit
H.264 video compression
High capacity of Lithium battery for power supply
Modular design and highly integrated
Adjustable working frequency
High strength aluminum enclosure, dustproof, waterproof and shockproof
NLOS (Non line-of-sight) transmission.
The transmission range is 20km in LOS (line-of-sight) condition
Good transmission with high definition video and stereo audio
Product Application
By using a pinhole camera, the first responder can get live scenes. Then the mini transmitter transmits real-time video to the receiving center. In the receiving center we use a rack mount receiver which can be installed in the van/vehicle to realize LOS / NLOS (non line-of-sight) condition
