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
