Features

  • Captures analog HD (AHD, TVI, CVI) and SD (NTSC, PAL) video over up to 1000 ft of coaxial cable
  • H.264 HP@L3 or MJPEG video compression
  • Supports MPEG-TS, H.264 VES, MJPEG over HTTP
  • Streams via HTTP, RTP, RTSP, UDP
  • Two independent output streams from one video input (for some resolutions)
  • AAC-LC audio
  • RS-232 port with Ethernet bridge

Model 2431 is a compact IP video server that captures, compresses and streams HD video and audio over Ethernet. It can simultaneously produce two output streams (one HD and one SD) with independent resolutions, frame rates, and bit rates, allowing it to be easily tailored to match network capabilities. Real-time text overlay is supported along with popular video processing functions such as image mirroring and rotation (180°), and frame decimation. Audio can be captured from a microphone or line source, or extracted from the SDI data.

Stream Formats
The video processor performs efficient H.264 video compression, producing output data formatted as transport stream, elementary stream, or RTSP. Alternatively, MJPEG compression can be performed, which is especially useful for capturing high definition snapshots. Audio compression is performed using AAC-LC. The stream multiplexer employs high precision hardware timestamps to ensure perfect A/V sync on players.

Real-Time Text Overlay
The text overlay generators can position up to 160 characters of monochrome text anywhere in the video frame. A unique text string, consisting of mixed constant and variable text, may be defined for each overlay generator. Text variables such as time, date, and frame count are automatically updated every video frame.

User Interface
The built-in web server allows device configuration and control, user management, and live stream previewing on any web browser. In automated applications, these functions can be accessed from a remote client through custom software (e.g., Curl, Python, Selenium) or multimedia frameworks such as GStreamer.
