Using IDX Cam-Wave CW-5HD wireless video transmission for live event coverage
16 years old. Gear and prices may have changed since.
What the thread found
- The CW-5HD can transmit stable video signals for live multicam productions over distances exceeding 100 meters indoors with minimal or imperceptible delay.
- Signal transmission works more reliably indoors than outdoors due to reflections.
- Transmitting in SD mode may provide better reliability than HD mode, though this was not definitively confirmed.
- When using the CW-5HD with a production switcher, genlocking the signal is necessary, and modern switchers with internal frame synchronizers can limit delay to approximately one frame.
- Range is approximately 20 to 30 meters in typical conditions, but actual performance can extend significantly beyond this depending on the environment and interference.
- Positioning the receiver as close as possible to the transmission area and mounting it at height improves signal reliability by providing a clear line of sight.
- The CW-5HD is unsuitable for broadcast television work but can work adequately for non-broadcast live event relays.
- Green line artifacts appearing on the display may indicate RF signal contamination from other transmitters or receivers in the vicinity.
Depends on
- The 2010 discussion reflects older equipment capabilities and may not apply to current hardware.
- Range and reliability vary significantly based on environmental factors including building materials, RF interference, and receiver placement.
- One user reported successful operation in an arena environment but later experienced interference issues that remained unresolved in the thread.
- Performance difference between SD and HD transmission modes was mentioned but not scientifically tested or confirmed.
