Product Description

System Introduction
The COFDM mini transmitter (MV2025 TWLE) 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 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/ ALLTECH Basic Scrambling
MPEG-2 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 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
