Description:

     SF-MR4H800P4 portable 4-way wireless image real-time transmission system, is our company's new generation of broadcast high-definition real-time image transmission system.Using the current leading COFDM modulation technology,has a relatively narrow bandwidth(2 / 2.5 / 4 / 8MHz) and a very strong anti-multipath interference capability,to overcome the multi-path reflection and blocking of images under analog technology and conventional modulation techniques,and realize, high-speed shooting and real-time non-line-of-sight (non-visual) transmission of high-quality images, especially suitable for use in complex environments; combined with efficient H.264 new digital video coding standards,the image can reach full HD 1080P, the solution can reach (1920 * 1080 compatible 1080I, 720P, 480P and SD), built-in high-performance lithium battery,can support the front-end 4-channel video signal at the same time,supports local real-time viewing and storage, two-way voice Intercom, and the device built-in 4G module, you can send the local image to the far end real-time. Widely used in public security, armed police, fire, electricity, emergency control, emergency and other environments.
