4K Encoder / Decoder with SRT

Product Features

TCS-8500 is a 4K encoder / decoder that supports SRT, Onvif, RTSP, RTMP, MPEG-TS, etc.
It is possible to switch between encoder mode and decoder mode by setting, and when operated in decoder mode, various video sources such as SRT, Onvif, RTSP, MPEG-TS can be decoded and displayed on a 4K monitor.
When operated in encoder mode, it can stream the video and record to a USB memory connected to the main unit at the same time.

– Equipped with SRT (Secure Reliable Transport) protocol
Advanced video transmission technology with security through encryption, reliability by packet loss recovery, and interoperability that enables networks connected with many different devices.
