Wireless HD video transmission with tally integration for Sony broadcast cameras without CCU
What the thread found
- Wireless video transmitters with built-in tally support compatible with Sony cameras like the PDW-700 and PMW-800 are difficult to find and typically exceed 10,000 USD when available
- The Teradek Beam was suggested as a potential solution offering RS-422 connectivity and IFB capabilities, though Sony cameras use a modified RS-422 protocol that requires special handling
- Sony cameras use a non-standard RS-422 implementation that flips between odd and even parity settings mid-command, but this can be worked around by sending the parity bit itself without validation
- Vislink's L1500 system was reported to offer full support for PDW-700 cameras including tally without requiring intermediate devices
- Most wireless transmitters on the market require either external tally lights or separate devices for different functions like serial communication, tally, intercom, and reference signals
Depends on
- Discussion dates from 2015-2019, so current product availability may differ
- No definitive confirmation that Teradek Beam successfully implements Sony camera tally in operational setups
- Solutions requiring intermediate devices like CNA1 adapters were considered less than ideal
- Price range of under 10,000 USD may not be achievable for fully integrated systems
- Range requirement of 650-1000 feet was mentioned but no specific products were verified to meet this
