Here's a video from YouTube member Kicapiproduction showcasing one of Wondlan's new Wireless Follow Focus System products. The new WFF is designed into a single unit that contains an 5" 1200x800 resolution HDMI monitor [thanks Kicap].
According to the details of the video, the wireless focus system is rated to have wireless range of up to 100 meters, but the the wireless monitor is only rated for a 30-60 meter range. I'm not sure what's going on with the use of an external HDMI cable to the monitor. It seems like they just threw an HDMI monitor inside of a case along with one of their existing Wondlan Memonic Wireless Follow Focus system (found here).

With more refinement i'm sure they can shrink the entire package down, keep all the circuitry internally, and actually make it one single unit. Looks like a cool system, but might be a bit early on the design right now. The unit isn't posted on their website yet, but i'll keep an eye open to how this new product develops.
