LT-124
Dual DVI capture card with hardware compression

The LT-124 is designed for capturing two DVI sources simultaneously, such as workstation displays or imaging systems. Two independent hardware encoders provide real-time H.264 compression from SD up to 1080p60 with minimal host CPU load, for reliable 24/7 operation.

  • Dual DVI-D 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
  • Optional audio input jack 3.5 mm
