Comparison of wireless video transmitters for professional use: Canatrans versus Modulus systems
18 years old. Gear and prices may have changed since.
DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- Canatrans transmitters have received consistent praise for reliability and customer service availability
- The Modulus 4000 did not reach production and remained a prototype that most users never saw in person
- Modulus 3000 units were no longer being manufactured as of 2008 and spare parts became difficult to obtain
- Customer support for Modulus systems was reported as inconsistent and unreliable after purchase
- Cramped Attic transmitters function as plug-and-play replacements for Modulus units with modern design improvements
- Measured transmitter output power varies significantly by model: Dynawave at 0.13-0.15W, Modulus 3000 at 0.18-0.2W, and Canatrans at 0.42-0.65W at 1W setting
- Range performance directly correlates with transmitter power output when operating on clear channels
- Channel interference from external sources such as nearby digital television transmitters can cut transmission range by approximately half
- MiniSpy transmitters achieve superior range due to single-channel design on a dedicated frequency but are not suitable for commercial use in the United States
- Some users found the Canatrans more expensive than comparable alternatives without proportional improvements in picture quality
Depends on
- Measurements were conducted in northern Mexico rather than under typical operational conditions
- The discussion dates to 2008 and equipment availability may have changed significantly since then
- Several participants reported opinions about customer service rather than systematic evaluation
- Whether the Modulus 4000 was truly vaporware or encountered development delays remains unclear from the discussion
- Frequency regulations and legality of equipment use vary by country and have changed since 2008
