Frequency selection for wireless video transmission when using a BFD wireless follow focus system

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

What the thread found

  • The BFD wireless follow focus system operates in the 900-927 MHz license-free band in the US
  • A 900 MHz video transmitter placed near a BFD receiver can cause the receiver to overload, resulting in loss of reception
  • Careful positioning and channel selection may allow a 900 MHz video system and BFD to coexist, but this approach is unreliable
  • A 2.4 GHz or 2.5 GHz video transmission system is recommended when using a BFD to avoid frequency interference

Depends on

  • The interference issue and recommended frequencies apply to US license-free band regulations
  • Success with simultaneous 900 MHz operation depends on specific equipment placement and channel choices, making it unpredictable
