S2 4K Video Encoder

S2 4K video encoder is an Ultra High Definition(UHD) video encoding device which supports 4K 30Hz resolution video input with H.265(HEVC)/H.264 encoding. HDMI video sources can be encoded and compressed over a wired network, to realize long-distance transmission and live broadcast for UHD video in network WAN and LAN.

S2 4K UHD video encoder supports 1 channel 4K UHD HDMI signal input with 1 channel 4K signal loop, it adopts H.265(HEVC) coding, which can transmit 4K ultra HD video in lower bandwidth with low latency while stable.

Ultra high definition, lower bit rate, lower latency video transmission.

• With advanced H.265/HEVC encoding technology, lower coding rate can be achieved. It can also transmit UHD video on low bandwidth network which can greatly save your network flow.
• Slice encoding technology ensures lower latency at the encoding side.
• Supports up to 4K 30HZ resolution.
• Wider adjustable code rate from 64kbit/s to 40Mbit/s.

Powerful streaming media service function, supports RTSP/ RTMP/ TS/ Onvif/ SIP/ GB/ T28181(Customized)/ NDI(Customized) and SRT protocols.

• RTP/ RTSP/ RTMP/SRT/ HLS/ TS/ Onvif/ SIP and some other streaming media protocols supported for live broadcast on Facebook, YouTube, Ustream, Twitch, Wowza etc or security platform / NVR system.
• SRT supported to ensure secure and reliable transmission.
• Dual stream output, the main stream code rate can be up to 4K 30Hz, and the sub-stream supports 720p 60Hz video encoding and customization available.

Portable size, image and characters overlay supported with functions of voice intercom, NAS storage, loop monitoring etc.

• Portable and low power consumption makes it 24 hours continuous working available.
• Capable with customized text and image overlay function, which can be at any position on the screen.
• Audio embedding encoding supported, with voice intercom function (need to deploy voice intercom software).
• Supports NAS network storage.
• With video real-time loop function, there is no delay and convenient for live monitoring.
