Overview

4K HDMI Encoder: The HEM-4K video encoder supports up to 2160p@30Hz HDMI or UVC input & 2160p@30Hz encoding output. It is a 4K SRT encoder to deliver secure, reliable, and low-latency video. Support H.265 HLS for 4K video broadcasting. 

USB-C Powered IP Encoder: Low power consumption with 4W only and powered by 5V/1A USB-C connection. With size in 85x63x23mm/101g, the encoder is neat and tidy enough to integrate with your live production system. It 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. Support H.265 & H.264 SRT, HLS, RTMP/RTMPS, RTSP, UCP/TCP, DDNS, Multicast, and Unicast.

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. 

Reserved Interfaces for More Features: The HEM-4K encoder comes with a variety of debugging interfaces 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. Support OSD and video preview. 

The HEM-4K Encoder is the DDMALL latest innovation for easier integration with customers' live production systems. It comes with semi-clear acrylic case in a compact form factor. With power consumption 4W, the low-power live stream encoder supports up to 2160p@30Hz UVC or HDMI input, and encoding ouptut is up to 2160p@30Hz, 64Mbps with built-in HEVC & AVC SRT, HLS, RTMP/RTMPS, RTSP, UDP/TCP, RTP, DDNS, Multicast, and Unicast. The encoder supports UVC video Input to capture the camera video for streaming directly, and it supports real-time switching between the HDMI input and UVC input. Moreover, the UVC input port supports Host USB mode and Device USB mode. In Host mode, it captures camera video; while in Deivce mode, it can be expanded to support USB data transmission with keyboard and mouse for remote PC control. The IP encoder also supports video recording to SD card or NAS system for storage. Support RS232 bi-directional communication protocol for control. The GPS interface is reserved to add GPS module for positioning, which is significantly making your streaming one-step forward. The encoder always works as an extension of your live productions, especially for the remote streaming, command dispatch, remote rescue and more. 

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. 

Neat & Easy Streaming System Setup 

The HEM-4K encoder comes with USB-C input and HDMI input ports that you can stream your IP camera video at ease. At the same time, it handles the switching between the UVC input and HDMI input in real time without interrupting your video streaming. Support up to 4K30Hz input and up to 2160p@30Hz encoding output at up to 64Mbps. It offers the most affordable and compact 4K live streaming solution for live productions. Support Multi-channel streaming with SRT, HLS, RTMP/RTMPS that you can push up to 4 streams simultaneously to live platforms like YouTube, Facebook, Twitch etc. 

DDNS Helps Control Your Stream Remotely 

The HEM-4K comes with bult-in DDNS that you can control the encoder through domain to edit encoder paramters and transmit video in public Internet without using third-party live platforms. It helps you manage your encoder no matter where you are! You can enjoy the freedom of accessing to your encoder as long as there is Internet services. 

Hardware Encoder Provides Low Latency Video Solution

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. 

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.
