  • 2 camera inputs for simultaneous capture in both channels
  • Windows CE Operating System
  • Full color Touch Screen interface
  • On-screen menu programming
  • Ethernet (TCP/IP) connectivity
  • 2 USB 1.1 high-speed ports
  • 2 RS-2332 serial ports
  • 'No Good' image storage holds 16 full-frame images 

Casa Herrera is the Authorized Sharpvision Group, USA Certified Integrator.

  • Automated inspection solutions for the food industry
