LT-122
Dual SDI capture card with hardware compression

The LT-122 is designed for dual-channel SDI workflows that require continuous recording or streaming. Two independent hardware encoders deliver real-time H.264 compression from SD up to 1080p60, offloading the host system for reliable 24/7 operation.

  • Dual SDI inputs with embedded audio support
  • Real-time H.264 hardware compression
  • Two channels hardware encoders
  • From 1920x1080p60 down to 720x480i
  • High reliability, 24/7 operation
