COFDM Range 2km Handheld Image Transmitter with Voice Intercom and Low Latency
The ZKManet1131T is a portable HD image transmitter. With low power consumption, small size and stable performance, it can capture and transmit high-quality images in real time during high-speed movement. It adopts COFDM modulation technology, encrypts the image and data during transmission, and is used with the back-end handheld receiver to form a close-beat wireless image transmission system. It is often used to close complex environments and block relatively many places.
The system utilizes omnidirectional antennas, allowing for the rapid establishment of wireless transmission links. Both the capture and receiving ends can be moved freely without directional restrictions, making the system simple, reliable, and flexible in application. In complex electromagnetic environments, it demonstrates excellent anti-interference capabilities against frequency-selective fading or narrowband interference, as well as superior performance in mitigating interference between signal waveforms. Through joint coding of various subcarriers, it possesses strong resistance to fading.
