Wireless video transmission systems for on-set monitoring at 2.4 GHz
20 years old. Gear and prices may have changed since.
What the thread found
- The Denz Video-Link AVL-01 operates at 2.4 GHz and features a diversity receiver, which helps mitigate signal interference issues common at this frequency band.
- The Teletest 2.4 GHz system has been reliably used for extended periods and includes transmitter and receiver boxes plus a 7-inch LCD monitor with integrated receiver.
- The Transvideo Titan system also operates at 2.4 GHz on four channels and offers proper connector types that reduce the need for custom cables.
- Devices operating at 2.4 GHz can tolerate hot 12V power supplies up to approximately 16V without degradation, whereas cheaper systems may fail under sustained higher voltage.
- Power and video distribution on ARRI rigs can be managed through various connector types including 2-pin and 3-pin small Lemo, 4-pin large Lemo, and 4-pin Hirose connectors, allowing flexibility in cable configuration.
Depends on
- Pricing information for the Denz Video-Link AVL-01 was not readily available during the discussion.
- Constructive and destructive interference at 2.4 GHz remains a fundamental limitation of wireless systems operating at this frequency.
- Availability of US dealers for the Denz system could not be confirmed in the thread.
- The exact type of diversity implementation on the Denz receiver was uncertain.
