Q: 7. Does anyone have experience using the Mars 300 where the transmission is not line-of-sight but must deal with walls or doors?

A: There are a lot of variables that come into play when you are not doing line of sight. The only way to truly be certain is to do a test in the space where you want to use it under similar conditions. The material of the walls, the distance, and Radio Frequency environment will all affect how well this system is able to send a video signal from the transmitter to the receiver.

Q: 8. It says pro version support 1080 at 59.94p but the monitor shows 1080 at 60p. Is there a way to select the output frame rate to be exactly 59.94p? Otherwise there are no benefits in 300 pro version compare to 400s version.
