Mars X is the only transmitter design which transmit the video from the camera to phones/tablets directly. 

The MARS X turns your phones/tablets into external monitors with a maximum transmission range of 300ft/91m, and a latency of only 0.07s. The image is transmitted via an internal WiFi network, which requires a password to connect. To avoid interferences, there are eight frequency channels available that you can switch with the button on the side of the unit.
