Stick up cam solid blue light come on when no one is watching it

Hi Has anyone experienced the same issue? The stick up cam came on in the middle of the night when no one is watching into the camera (motion detection is off). And the solid blue light will goes off after I spotted/looked into it This happened several times, it stopped for a period of time after I changed the wifi and app password. And it just happened again I am really concerned about the safety of using these cameras. I thought it would be safer to use these cameras around the house, but it seems the other way round
