Product Overview

ANT-38500 4K UHD HDMI,HD-SDI & Composite Input ONVIF H.265 or H.264 4KP60 Video Encoder or Decoder, capable of up to a maximum 4096 x 2160 at 60 fps (frames per second) using an IP LAN ethernet connection. This product replaces the ANT-38000.

The inputs are HDMI with full ONVIF profile S control for integration with VMS software, such as Milestone / Exac etc. The inputs and outputs are provided to allow for signal bypassing or looping. This product can also be used as a decoder.

Multiple streaming formats are supported such as MPEG-TS, UDP, HTTP, SMTP, FTP, DHCP, DNS, dDNS, RTP, RTSP & SNMP.

The encoder has on board recording via USB for monitoring and litigation purposes and can be powered via 12V or PoE.

AAC and G711 two way audio is supported with embedded audio in HDMI or analogue stern jack (1vpp).

RS232/485/422 2 way serial data communication, motion detection , sensor and alarm I/O.

Rack mountable with 1U rack mount kit available supporting up to 3 encoders.

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.
