★★★★★Global Operator 31· Dec 22, 2020
Great app, use this for security on my artic truck one camera facing down the passenger side (Were the diesel tank is) (Infred) and another facing the front. Camera downside is a USB megapixel. Ip camera (amazon) recording to 64 GB Usb stick with a Samsung Note 9 as a screen..... I have found that I can't use 2 camerae of the same type together front facing one is a Webcam .... also any chance of a zone alarm system, so I can put square on the screen so that when someone enters it alarms

Works as advertised. Helped me a lot with my SXS vehicle to have front & rear camera always displayed. Only thing so far I don't like and why I gave 4 stars is automatic picture in picture mode has black screen of app still instead of restoring as if you had it manually set

Help, only 1 cam is on, error msg: connected 2 devices but 1 devices permission not granted (head unit android 10, 6gb ram, octa core arm cortex)

With a single ELP stereo vision camera I'm getting a single picture out and a second picture which only comes up when you put your finger really close to the ELP camera only when MJPG conversion is set to off. And in that mode the second eye the left eye no matter which one I choose is always a very streaky camera. I think it's a problem with this app. Please fix and score will be raised.

Great concept, but missing a crucial feature. The app perfectly displays two USB feeds side-by-side for VR headsets with minimal latency. It's ideal for DIY projects. However, the total lack of adjustable image spacing is a major flaw. Many headsets require a small black gap between the pictures to align with the lenses. Without a spacer or IPD adjustment slider, the feeds don't merge correctly on certain viewers, causing heavy eye strain. It needs a layout update to be truly usable.
