Compatibility and performance characteristics of the CW-5HD wireless video transmitter with cinema cameras

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

What the thread found

  • The CW-5HD works with the Epic camera when connected to the video output and produces usable signals without glitches during high-speed recording.
  • Firmware version 1.3.0 improves out-of-range re-linking speed so the transmitter does not need to return as close to the receiver to restore connection.
  • Firmware 1.3.0 eliminates spurious frequency appearances on random channels that occurred when the transmitter was initially powered on.
  • The CW-5HD does not properly handle true 24FPS video signals despite supporting 1080p/23.98PsF and other standard formats.
  • Hardware upgrades involving EPROM chip replacement require service at the manufacturer facility and take approximately 20 minutes.
  • A hardware revision marked with the letter D in the serial number represents the latest production version.
  • The CW-5HD achieves transmission range of 200 to 300 feet outdoors on an open backlot with standard equipment.
  • Third-party antenna additions provide approximately 10 to 20 percent increased transmission range but may void the two-year warranty.
  • The CW-5HD performs poorly in RF-dense environments like casinos where signal reflections interfere with picture lock.
  • Firmware updates must be performed by the manufacturer rather than downloaded for home installation.

Depends on

  • Practical experience described is limited to episodic television and feature film production, not live broadcast work.
  • Performance comparisons with competing systems like the Boxx Meridian are based on limited day-player experience rather than extended use.
  • Outdoor range testing was conducted on a specific film studio backlot and may not represent performance in other RF environments.
  • The warranty implications of third-party antenna modifications are unclear and warrant confirmation with the manufacturer.
  • The discussion does not address whether newer firmware versions maintain or resolve the FCC-compliant transmission power limitations.
