This video encoder device implements H.265/H.264 video encoding and audio codec, the stream will output via Ethernet after encoding. One channel uart data can also be packed with the stream and output to the Ethernet. The video encoding bitrates is controlled via web UI.

This device is compact in size and suitable for real-time live video monitor via wireless link or Ethernet. We have two options:
* HDMI, Mini HDMI/AV video input
* SDI, SDI/AHD video input

Video and audio input

SMA female connector for SDI HD video input, 4PIN ZH1.5mm connector for AHD input. The AHD input is AV-compatible. SDI input model supports one-channel video input and encoding with default firmware. The system will auto-detect the input video after system start-up. When SDI video and AHD video are connected in, the SDI input or the specified input (via Web UI) is the priority. The SDI input model can also support both SDI input and AHD input and encode two-channel videos at the same time with specified firmware.

• Support SDI video input formats: 1080@60P, 1080@50P, 1080@30P, 1080@25P, 1080@24P, 1080@60I, 1080@ 50I, 1080@30I, 720@60P, 720@50P, 720@30P, ……
• Support AHD video input formats: 1080P30, 1080P25, ……
• Support AV video input formats: 720*480 60I(NTSC), 720*576 50I(PAL)
• Video encoding: H.265/H.264, setup via Web UI
• Video encoding bitrates adjustable via Web UI
• Supports proprietary H.264 video compression only using p-frames for the lowest latency(the encoding and decoding latency is about 80ms to 150ms when working with our H264 decoder module).
• When paired with the H265 decoder module, the H.265 encoding/decoding video latency is about 200ms to 250ms.
• Audio input: embedded SDI or analog audio
• Audio coding: AAC, 16bit, stereo, 32Kbps

Data UART

3PIN ZH1.5mm connector, RS232 by default (can be modified to TTL3.3V before ship out). This UART data will be packed with the video stream and output to the Ethernet. When this device module works paired with our decoder module and Ethernet linker (wireless or wired), the data to this UART will be transferred to the data UART of our decoder module.

SPK interface

2PIN ZH1.5mm connector. When this encoder is paired with our video decoder module, this device system is capable of decoding the audio stream from our video decoder module which is received via an Ethernet port with a wired or wireless connection, and the audio will output to a speaker. This interface is used for connecting the speaker. It can drive a 1W speaker directly.

Ethernet interface

4PIN ZH1.5mm connector, RTSP/TS stream output, TCP/UDP protocol, setup by Web UI.

Encoder and Latency (Delay)

H265

This encoding board is matched with our H265 decoding board and wireless transmission link, and the video delay is about 200~250ms.

H264

This encoding board can be configured for ultra-low-latency H264 encoding mode (via the network port Web method or serial port configuration). With our corresponding decoding board and wireless transmission link, the delay of 1080P high-definition video (1080P) is within 130ms, and AV SD video latency is within 100ms.
