System Introduction
The 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
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 portable multifunctional suitcase receiver that can record the real-time video by TF card and control the PTZ in NLOS (non line-of-sight) condition
