Wevi’s wobble but they don’t break up
Art Adams | 07/31
IDX’s new Wevi CW-5HD wireless HD system will have you looking for hidden wires and cackling maniacally when you don’t find them
If you want all the specs and details, click here. The short version: it mounts like a V-mount battery, draws a fraction of the power necessary to run the RED, is small, compact, light weight, easy to use, easy to power, and transmits a very pretty picture.
This is where John took the RED:

(That’s John holding the camera, with prep tech Mecky ready to save it in the event of a hit-and-run.) At this point the camera was outside the rental facility while the receiver was inside, about 50’ away. Here’s the image we saw:

It was extremely clean and nearly indistinguishable from a wired feed. (Any defect you see in this image is due to capturing it at low resolution off a Leader 5750 waveform/vectorscope.) We didn’t run into problems until Mecky took the camera farther across the street:

At this distance, approximately 120’ from the receiver, we started seeing some hits, although the picture was still viewable and looked a lot like the kind of images we’re used to seeing from previous generation video transmitters in a best-case scenario. When Mecky took the transmitter down the street, placing a brick wall and a vehicle or two between the transmitter and receiver, the image fell apart into small blocks until it was completely lost. There was no occasional reacquisition of the signal; once the signal was gone it stayed gone until it became strong enough to read reasonably well. This unit doesn’t tease. There’s either a picture or there’s not.
John was quick to point out that we’d probably get better results if the transmitter was inside with us or if we were outside with it.
It looks like we now have a wireless option for mounting RED cameras on Steadicams without having to watch a nasty, broken down-converted standard-def signal. Apparently there are many possible configurations, including broadcasting one signal to many different receivers.
If you need it tomorrow, or before anyone else has one, call John, Jay or Erin at Chater Camera. If they say it’s in use, request that John get out of the street and knock off the gleeful cackling.
