T-POV Systems

Bidirectional HD & 4K Video/Audio/Data Robotic Camera Links

The T-POV line offers significant improvements in bidirectional fiber optic video and data transceiver technology for robotic point of view HD television cameras. These devices are an outstanding choice for sports, remote broadcasting, security, education or military applications. Most are TelePort 3G and TeleThon 3G compatible with more flexible and affordable integrated SMPTE hybrid powering options and distributed power supplies. There's now an Ethernet option and the 324 model offers a return HD-SDI option.

FEATURES

  • Bidirectional on one or two fibers
  • Uncompressed HD-SDI up to 3 Gb/s
  • Up to 4* duplex RS-232/422/485 data channels for full camera control and pan/tilt/zoom
  • GPI relay closure circuits
  • Return genlock, or tri-level sync for HD
  • 4 audio channels in each direction*
  • Use dry fiber or SMPTE hybrid cable
  • 10/100 Ethernet*

    • Rack mount holds up to 3 units
    • Throwdown for single applications
    • Robust Mini-Mussel shell for harsh-environment applications
  • Wide temperature range
  • High reliability design


*Features vary by model

*Available signal paths vary by model

**The maximum cable length varies due to optical loss that can depend on cable quality, dirt/dust/contamination on connectors, and number of fiber interconnects. When using hybrid cable for power, the size of the hybrid cable, as well as the power draw of the camera, lens and pan/tilt head are also factors.
