COFDM Wireless Video & Audio Transmitter with Video ON/OFF Control

उत्पाद अवलोकन

इस professional-grade COFDM wireless transmitter is specially designed for mobile surveillance, vehicle-mounted operations, and tactical monitoring. The unique feature is a dedicated button to disable video transmission while keeping audio active. This allows operators to switch between full audio-video mode तथा audio-only mode instantly, depending on the mission needs.

With robust COFDM modulation, the system ensures स्थिर, non-line-of-sight transmission within a 2 km radius, even in urban or complex environments. The receiver can be deployed at a high vantage point or control center, ensuring uninterrupted monitoring.
