Datasheet of ON-AHD-16EM
Overview
EXVIST ON-AHD-16EM – 1080P AHD Encoder w/SD Card & Multi-Protocol Streaming
The EXVIST ON-AHD-16EM is a compact embedded AHD encoder that converts analog AHD video (up to 1080p@60fps) into H.265/H.264 network streams. It supports simultaneous streaming via RTMP, RTSP, SRT, HLS, TS, UDP, and Multicast. With a built-in microSD slot (up to 128GB) for local recording, ONVIF/Hikvision compatibility, cross-browser web UI, and ultra-low latency (70–140ms), it is ideal for live broadcasting, IPTV, CCTV surveillance, video conferencing, and remote teaching.
Application Scenarios
- Live broadcasting to YouTube, Facebook Live, Twitch, Wowza, and RTMP platforms
- IPTV systems and multicast streaming for hotels, campuses, or enterprises
- CCTV surveillance with NVR integration (ONVIF, Hikvision iVMS-4200/8700)
- Video conferencing and telemedicine systems
- Remote teaching, e-learning, and major events streaming
- Esports and video game live streaming
- WeMedia and personal live streaming with HLS for mobile viewing
Hardware
Advantages
- Multi-Platform Broadcasting – Supports pulling streams via TS (H.265/H.264) to any server and pushing RTMP (H.264) directly to Wowza, YouTube, Twitch, Facebook Live, Livestream, Wirecast, vMix, and more. Also supports dual-address push streaming.
- Comprehensive Protocol Support – RTMP, RTMPS, SRT, RTSP, HLS, TS, UDP, Multicast, HTTP, HTTPS, ONVIF, and Hikvision private protocol. Works seamlessly with iVMS-4200/8700 and Hikvision NVRs (H.265 recording supported).
- True Cross-Browser & User-Friendly UI – Live preview and full configuration on IE, Edge, Chrome, Firefox, and Safari. Insert logo (JPG 200×200), add OSD text, set AAC audio, adjust bitrate, and remotely upgrade firmware – all from the browser.
- Ultra-Low Latency & Flexible Streaming – Stream latency as low as 70–140ms (PC-to-encoder + decoder HDMI output). Supports 6 concurrent RTSP streams, adjustable bitrate (64–12000 Kbps), dual-stream encoding (main/sub), and 1080p@60fps encoding performance.
- Compact & Rugged Design – Tiny footprint (38mm × 38mm × 8mm) and lightweight (9.5g), making it easy to embed into any system, install in tight spaces, or use in mobile applications.
