Product overview
The Kimpok Technology KP-HDT20W-1 is a wireless video and audio transmitter for UAV filming, broadcasting and real-time image monitoring. Its architecture combines video encoding, COFDM digital modulation and a power amplifier, with two cooling fans and an OLED control panel. The transmitter measures 220*140*66mm and weighs 2.5kg. It operates from DC12V with working current of ≤6A at that voltage, across a working temperature range of -25°C~55°C. AES 128-bit encryption is provided for the wireless transmission.
Output power is adjustable from 10-20W, with 300-900MHz operation or customized alternative frequencies and adjustable 2/4/6/8MHz RF bandwidth. HDM/SDI and CVBS video inputs accompany optional RS232/TTL data input at up to 115200bps. Video formats include 1920*1080P/I@60fps and 1280*720P/I@60fps, with MPEG-2/H.264/H265 coding. The receiver configuration has an N-type, 50Ω RF input and a 1U chassis weighing 1.5kg. Its power requirement is AC220V/DC12V, less than 1A, and its working temperature range is -20°C~+50°C.
