Introduction
The mini transmitter is highly integrated digital video transmission equipment that 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 (technical investigation and covert intelligence gathering). It can be also applied in emergency and evacuation, railway, marine and so on. We can use the mini transmitter with a specially designed multifunctional amplifier to meet the requirement of longer transmission range.
Features
COFDM modulation, Stable transmission
MPEG-2 video compression, DVD video quality
Mobile and NLOS (Non line-of-sight) transmission
High strength aluminum enclosure, dust-proof, water-proof and shock-proof
Lithium battery for power supply (continuous working time of every battery is an hour)
Modular design and highly integrated
Adjustable working frequency
Can be used conveniently with the specially designed clothes
Transmission security by encryption of AES 128 bit/ ALLTECH Basic Scrambling
Matched with power amplifier for longer range; Up to 80km in LOS (line-of-sight) condition
Application
The product is an ideal solution in remote surveillance, designed specially for the covert intelligence gathering market. By using a pinhole camera, the first responder can catch live scenes at the accident ground. Then the mini transmitter sends real-time images to the receiving center.
