Overview

4K HDMI Video Encoder: Max. HDMI or UVC input in 2160p@30Hz, & max. encoding output in 2160p@30Hz at 64Mbps. Built-in HEVC and AVC codec, stream with SRT, HLS, RTMP(S), RTSP, RTSP-to-SRT, RTP, TCP, UDP, Multicast, Unicast. 

USB-C Powered: Low power consumption of 4W; Powered by 5V/1A USB-C connection. Size in 85x63x23mm/101g. Comes with semi-clear acrylic casing that you can take the housing off according to your scenario needs. 

Two USB Modes: The USB-C input port supports both USB Host and USB Device modes. In Host mode, it captures UVC image; while in Device mode, it can be expanded to support USB data transmission with keyboard and mouse for PC remote control. 

UVC Video Input: The streaming encoder supports UVC video input to stream USB camera video to live platforms directly. Support real-time switching between HDMI video and UVC video without glitches.

Remote Control & Live: The hardware encoder supports DDNS that users can remotely control the encoder through domain to modify parameters and transmit video in public Internet without using any third-party live video platforms. 

SD Recording & NAS Recording: The low-power encoder supports recording during streaming that you can record your video to SD card or NAS storage system. 

Low Latency Video Transmission: The HEM-4K encoder comes with built-in DDMALL proprietary Low Latency protocol. When pairing with DDMALL low-latency decoder HDD-20 or HDD-10, you can enable the Low Latency protcol for video transmission in LAN that the latency is as less as 80ms. Contact us to custom even lower latency products if you have such requirements. 

Reserved Interfaces for More Features: Debugging interfaces are reserved to realize customized development requirements such as diversified control and GPS positioning. Support RS232 bi-directional communication protocol and supports access to modules such as GPS positioning and Analog audio input. 

OEM Module for DIY: Contact us to get the hardware design guide of the I/O board. So you can craft a totally new and powerful HDMI encoder. The encoder always works as an extension of your live productions, especially for the remote streaming, command dispatch, remote rescue and more. 

More Features: Support OSD and video preview. Support encoding 4 streams at the same time with different protocols. Support one click to start/stop RTMP streaming. Support NTP sync and clock OSD. 

4K Low-Latency SRT Encoder for Live

The HEM-4K HDMI encoder is with built-in H.265 and H.264 SRT protocol. It delivers secure, reliable and high-quality SRT video streams. No fair of congested network anymore. At the same time, It supports H.265 HLS that users can playback 4K ultra-HD video with the iOS terminals. 

Track your Live Video Position with GPS 

The HEM-4K comes with GPS interface for the access of GPS module. With the GPS positioning, you can easily track your streaming live status. No matter where you are, you can monitor the latitude, longitude, position, altitude, speed, satellites number, date and time of our live video so that you can take crucial measures timely. This function significantly improves the efficiency of strategy making and changing especially for command dispatch, remote live productions, remote rescue etc.
