Product Overview

ANT-38500 is HEVC 4K Encoder / Decoder that could be applied to various applications such as broadcasting, house of worship, video surveillance, sports event, Medical etc. using multiple transmission protocols such as NDI, SRT, Onvif, RTSP, MPEG-TS etc. The ANT-38500 can be used as an Encoder or Decoder for End to End solutions with reliable, high quality and low latency video transmission. When the ANT-38500 is set as a Decoder it can receive A/V IP data over a network via various protocols such as MPEG-TS, RTSP, SRT, Onvif and HDMI output to a monitor.

The ANT-38500 has ability to record files locally to USB attached storage while A/V is transmitted over a network at the same time. This recording feature can reduce the risk of network congestion during peak times and prevent loss of files due to network connectivity issues or errors.  Using RS-232/42/485 and various PTZ protocols including Sony Visca, Panasonic etc, the ANT-38500 can be connected to a high quality Broadcast PTZ camera via HDMI and controls the pan / tilt / zoom over the network.
