Sistema de indicador de cuenta de RF inalámbrico para operaciones de cámara de transmisión
Tiene 14 años. Es posible que el equipo y los precios hayan cambiado desde entonces.
Lo que encontró el hilo
- Se puede construir un sistema de contador inalámbrico con un transmisor montado en la parte superior de una cámara sled utilizando un sensor de fotocélulas para detectar la luz de la cuenta de cámara, y un receptor separado con indicadores LED colocados en otro lugar en la plataforma o monitor.
- El prototipo logró un rango de transmisión inalámbrica de aproximadamente 150 pies.
- The system can run on 12 to 18 volts for the receiver and uses a 12-volt battery internally for the transmitter, eliminating the need to run cables down the outside of camera rigs.
- Photocell sensitivity requires adjustment during camera checks to ensure reliable operation throughout a production.
- Field testing over a full outdoor broadcast operation showed the system functioned without issues after initial photocell calibration.
- A four-pin XLR socket on the receiver allows flexible power input from various 12-volt sources such as sled power outputs or D-tap connectors.
Depende de
- This was a prototype and proof of concept that underwent limited field testing.
- The final production configuration had not been completed at the time of the discussion.
- Initial design used mixed power sources (9-volt and 12-volt batteries) that were intended to be consolidated into a unified 12-volt system.
- Photocell sensitivity required manual tuning and may vary depending on ambient light conditions and camera tally light design.
