with 180 FOV, otherwise how would you know if you have everything in frame when shooting handheld?
The point of this action camera is that it captures everything in front of the camera 180° wide angle so it is no longer critical. It's a completely different shooting philosophy. Even different between shooting 360 vs 180 is different. The best way to shoot 360 is to mount the camera on a monopod and then get away from it and let it capture everything. I've been trying to use the 360 cam in walking tour and it is very difficult as the stitching lines do not match well when your face is close up. The technology is just not good enough yet. So holding the 360 out in front at arm's length is the best you can do. VR180 solves this since it doesn't capture behind the camera plus the resolution in the HMD is doubled adding far more detail in the scene. This was really noticeable. Even cropping the 360 to 180 gets rid of the close up person holding the camera but doesn't help with the resolution.
But, let's consider that you are doing a scripted event and MUST follow the director's camera moves. Yes this might need the monitor. I used to work this way in business so I know the drill. The wide angle of a 180 capture makes it far less critical since scripted shooting can and usually is edited in post. But say it isn't. Directed shooting, whether working under a director's orders or you direct your own scripted moves, adding the iphone display is fast and easy if they did it the way they did with my Vuze 360.
When I sot with the VR360 up on a monopod above my head, I used the iphone remote screen to control record / pause as well as see that the camera was level as I walked through my planned path. To use the screen and controls was as easy as launching the app and hitting the wifi button on the camera. In 2 seconds I had all 4 camera angles in view. There are 6 cameras on the 360 but there is no need to see the stereo pair. In a more complicated system the higher end Vuze 360 offers live streaming and stitching to stereo if you have a computer with a 3D monitor. I saw this in action at NAB but I just have no need for that.
GoPro added LCD's for a reason, sure you can use them without, but why not have an LCD if given the choice?
First of all GoPro is not a VR camera and it's shooting is much more limited in FOV than a VR180. However, the GoPro also offers the option of remote streaming and my gimbal for the GoPro even has a mount for the iphone. If you use several GoPro's in a VR system there is no live streaming nor monitor either.
My GoPro 3D rig eliminates the monitor, so I added a 3rd GoPro for recording 4K in alignment and it has a LCD back for aiming. I wouldn't be without it the screen on the GoPro 3D camera system. But it is mostly unnecessary on a VR camera except when I need to operate remote control.
If you don't plan on doing action shooting for VR best viewed with an HMD then the VuzeXR is the wrong tool. Stick to flat screen TV cameras.
