A few weeks ago we had the opportunity to test drive the Varavon Wirecam. The Wirecam is a Cable Cam system that flies a camera over a rope tied between two points. Although the affordability and use of drones are increasing for aerial imaging, there are still many instances in which a Drone would either not work, would be illegal, unsafe, or would be just a noisy nuisance.
Unlike most Drones that could only fly for about 20 minutes, the Varavon Wirecam could go for hours at a time. Not to mention if you wanted to fly a larger camera than just a GoPro, you'd need a fairly large Drone. In our example we were able to fly a DJI Ronin-M + GH4 + 12mm Rokinon Lens + Radian Wireless Video System. Now that we've made our point that Drones can't solve everything, here's a quick montage video (below) of us setting up and operating the system.
Operating the Varavon Wirecam was extremely simple to operate as it only moves either left or right and the entire system weighs only about 7lbs (without camera). Of course this is not a tool you should show up with without some type of practice setting it up. You'll want to get a few hours in getting familiar with tying down the line, mounting your camera system, and any other accessories.
Setting up Varavon Wirecam Cable-Cam System
The most difficult part about working with the system is finding a good place to attach the rope. Our warehouse project had plently of steel beams, but out in an open area is where you'll need to be creative. When attaching the Rope, you should brush up on your knot tying skills, carry a set of ratcheting tie downs, and I highly suggest using a Manual Come-Along to pull the braided rope tight. These will make life much easier, and you'll find that with a brand new braided rope, the braids will tighten and eventually produce enough slack that you would have to re-adjust 2-3 times before it starts settling in.
You can mount a camera directly under the Wirecam, but a gimbal will help to stabilize the horizon. And If you're using a gimbal like the DJI Ronin-M that comes with a remote, you'll also be able to control Pan + Tilt as the Wirecam flies.
Of course in order to frame a shot, you'll want to stream the video feed back from the camera. In our setup, we used the Camera Motion Research Radian Pro System. So as one operator controlled the Wirecam, a second operator controlled Pan + Tilt on the DJI Ronin-M Gimbal, and both operators shared a monitor.
The Varavon Wirecam is a great option for high flying aerials when a drone system just won't cut it. I could see this cable-cam system being used heavily in sports on the sidelines of a field, lap pool, motocross track, or other events in which the camera needs to constantly repeat a forward / back or left /right tracking shot.
