S2 H.265 4K Video Encoder

• 4K HDMI Input
• Lower Bandwidth
• Better Image Quality

S2 4K Video Encoder

S2 is an UHD 4K video encoder which is designed to meet the needs of all 4K video transmission applications. The input resolutions is up to 4Kp60 and encoding resolutions is up to 4Kp30. It supports H.265 (HEVC)/H.264 high-performance encoding. Also, it supports the most protocols including NDI|HX/SRT/RTMP/RTMPS/HLS/UDP/RTSP/Onvif, etc.

Adopt H.265 to save over 50% bandwidth

With H.265 HEVC encoding, S2 realizes lower encoding bitrate and save more than 50% bandwidth with same image quality comparing with H.264. (Typical encoding bitrate: H.265: [email protected],H.264: [email protected])

4K transmission to ensure better image quality

With HDMI 2.0 input, S2 supports real 4Kp60 HDMI input and encodes up to 4Kp30. Besides, it is compatible with SD/HD/VESA resolution etc., to meet your needs for a high-quality image.

More Protocols Supported

S2 supports RTSP/RTMP/RTMPS/HLS/TS-UDP/Onvif1.1/2.0/ and NDI|HX, so users can live stream with RTMP/RTMPS, live production with NDI|HX and remote production with SRT, all can be handled at the same time with one device.

Support SRT/NDI/NDI|HX etc

S2 supports RTSP/RTMP/RTMPS/HLS/TS-UDP/Onvif1.1/2.0/ and NDI|HX, so users can live stream with RTMP/RTMPS, live production with NDI|HX and remote production with SRT, all can be handled at the same time with one device.

Powered by PoE & DC 12V

Driven by PoE/5-18V DC/camera battery

S2 is easy to use since it can be powered by PoE and DC 12 V. One ethernet cable can supply power and transmit signals at a time.

Powered by PoE as well as DC5-18V wide range voltage power supply, makes S2 convenient to use.

Application scenes

S2 is widely used in broadcast/conference/program/live streaming and other video IP transmission, interactive connection, video network recording, integrated media projects etc..
