I installed the Zenfox T3 3 channel camera system in my Acadia. The screen on the camera itself shows all three cameras at once, however the screen is too small to see much detail. I loaded the Zen fox application to my iPhone 12 to connect to the camera. I was able to set up the options that I wanted. However, the live view screen is always black. It does not matter whether I hard reset the phone, uninstall and reinstall the app, the screen is still black. After reading reviews it seems like this is a common problem and the company really needs to take this issue seriously. It’s too bad a really awesome camera system is not able to be utilized effectively because the app is broken.
