Known quirks

  • When using the external monitor function via wireless connection (Wi-Fi), the camera’s video recording will stop if you turn off your smartphone’s Bluetooth or exit the app during video recording. Please do not turn off Bluetooth or close the app while using the external monitor function. If you want to prioritize the camera’s video recording, please use a wired connection (USB).
