The IDX CW-1 is great to link a camera with a monitor video without cable. It's light and compact compare to cinema models. You can plug any camera with an HDMI out. To power the transmitter I provide the apdater for Sony NP-F batteries. I have this adaptateur for the receiver too and the DC-in. Even with the adapter and a battery, the transmitter and the receiver are light and compact and can be handle. With the clamp for flash slot you can attach the transmitter on the camera.
