Paralinx Arrow uncompressed wireless HD transmission system capabilities and limitations

14 years old. Gear and prices may have changed since.

What the thread found

  • The Arrow transmitter is compact and powered via USB, with a receiver about the size of a 3x5 card and 1 inch thick, both designed for portable use on sets.
  • The system advertises 320 feet line-of-sight transmission range and 150-200 feet with obstructions, using enhanced antennas and power amplification compared to consumer WHDI sticks.
  • Transmission is uncompressed with sub-2ms latency, allowing reliable on-monitor scoping and histogram readings for camera operators.
  • The system requires 7-10 seconds to lock signal initially and the same time to recover if signal is lost during a shot, which could cause production delays.
  • HDMI is the only connection type available; achieving HD-SDI compatibility requires adding converter boxes like a Decimator 2 on both ends, significantly increasing system cost and complexity.
  • Total system cost with necessary converters reaches approximately $1,985, which is still notably less expensive than competing wireless systems like new Canatrans or Switronix Recon.
  • If a camera has HDMI output, the Arrow can connect directly without requiring external converters like a Decimator 2.
  • The system was initially priced at $995 during CineGear 2012, then increased to $1,195 after the show ended.
  • Multicast capability allowing one transmitter to work with multiple receivers was under development but release timeline was not provided.

Depends on

  • Testing was limited to demonstrations at CineGear; real-world on-set performance had not been comprehensively verified at the time of discussion.
  • The HDMI-only connector type makes integration into professional HD-SDI workflows difficult without additional conversion equipment.
  • Manufacturer stated no plans to release an HD-SDI version, though some participants believed this position might change after seeing industry demand.
  • Signal recovery time could be problematic on larger professional productions with multiple crew members monitoring video village.
  • Power input via USB rather than professional power connectors like D-tap was considered less robust than industry alternatives.
  • Performance of the system indoors versus outdoors had not been fully tested by participants.
