We put the COFDM receiver on the top of our building andput the transmitter on the moving car. Our engineers drove the car along with the road in the city with many high buildings. The camera looked forward outside.
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
Main Features: ■COFDM modulation, Stable transmission ■MPEG-2 video compression, DVD video quality ■Mobile and NLOS(Non line-of-sight) transmission ■High strength aluminium enclosure, dustproof, waterproof and shockproof ■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 multifunction amplifier for longer range requirement. The transmission range can be up to 100km in LOS (line-of-sight) condition
Product 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.
The COFDM mini transmitter is a new concept in remote surveillance, designed specially to meet the special requirements of covert missions. This product is modular design and highly integrates the antenna, digital modulation and AV compression into one. Every lithium battery can support the system to work for an hour continuously .If used with the multifunctional amplifier, longer transmission range can be up to 100kms in LOS (line-of-sight) environment. In the receiving center we use a portable multifunctional receiving suitcase(MV2025R/YJBK) that can record the real-time video by USB interface and control the PTZ in NLOS (non line-of-sight) condition.
