The CineEye Air is the younger brother of the CineEye and is priced at a meagre $149. It will support only up to 2 smartphones at a time.
According to BHphotovideo.com :
CineEye Air simultaneously transmits up to a 1080p video signal from an HDMI source to two iOS/Android mobile devices such as smartphones and tablets, treating them as video receivers and allowing you to use them as real-time video monitors. The signal is sent from its full-size HDMI type A input over 5 GHz Wi-Fi up to 328' line of sight with a low latency of approximately 50 ms. A companion CineEye iOS/Android app provides features such as false color, peaking, zebra, and histogram, as well as .cube format 3D LUT support, allowing your devices to function as professional video monitors. The CineEye Air can be used for standard monitoring, remote focus pulls, and various other applications on set and otherwise.
The CineEye Air is made of durable aluminum, and it has an ultra-compact, pocket-sized design that weighs only 4 oz. The 5 GHz Wi-Fi signal is more resistant to interference than standard Wi-Fi, so Wi-Fi reliability is at its optimal with the CineEye Air. You can power the unit using the included USB Type-C cable or a DC source using its barrel input. The CineEye Air can easily be mounted on your camera or other video device using its 1/4"-20 mounting thread as well as using the included shoe mount.
