Picolo U4 H.264™: Optimized Capture and H.264 Compression Card for 4 Video Inputs with Audio Capability

Picolo H.264 Series: High-Quality Video Capture and H.264 Compression Cards
Full Datasheet



  • Picolo H.264 general features
  • 4 real-time PAL or NTSC video inputs
  • H.264 on-board compression, 100/120 ips at full resolution (25/30 ips x 4)
  • 3 simultaneous and independently configurable output streams per video channel:
    - Two H.264 compressed streams
    - One raw uncompressed stream
  • 4 high-quality audio inputs
  • 8 professional I/O lines and watchdog capability
  • One selectable video output with cascade capability
  • Form factor: PCI Express x1 full-height, half-length


The Picolo U4 H.264 is high-quality video capture card featuring real-time H.264 on-board compression for 4 video channels along with audio capability. This card offers cost effective acquisition and compression delivering three independently configurable output streams for each video input: two compressed streams and one raw uncompressed stream.


Easy and quick integration in any video surveillance application

- Simple and convenient standard-based drivers:
  • DirectShow Drivers for Windows® (32-bit and 64-bit)
  • Virtual File System Drivers for Linux (32-bit and 64-bit)


- Connecting accessories

  • HD44M to female BNC Breakout Cable for video (in, out and cascade) signals
  • HD44M to female RCA Breakout Cable for audio signals
  • FTSH34 to HD44F Adapter for the Picolo U4 H.264 card: it brings the video, the audio and the Professional IO signals from internal connectors to an HD44F connector.
  • Audio-on-Bracket Link for Picolo U4 H.264: it connects the audio and video signals to the HD44 connector of the card bracket.


- Available as a predefined component of CamID (PRELIMINARY) for simple and convenient design, programming and maintenance of surveillance applications
