yi dome webcam shuts off after 1 minute

My dome Yi 1080p webcam turns on, I get a yellow light for 60 seconds / 1 minute, then shuts off I have 2 dome black webcams that do the same thing, i find it odd>? That they both turn off after 1 minute, ive tried replacing the power plugin and just plugging in the USB connector into my computer usb and the same thing they both turn off after a minute?? Any ideas

That’s very strange. Especially that its happening to 2 different camera models.

Do you mind if I ask how you are using the cameras? You said webcams.
Are you using SD cards?
Have you tried resetting the cameras?

Looking forward to your response.
