Indoor camera solid red light

We are trying to figure out why once or twice a day usually early in the morning or late in the evening our indoor cameras have a solid red light appearing. It clicks off the moment we try to get a picture of it and the cameras are always disarmed at the time of the light appearing. It seems to be happening like clockwork at the same time pretty much every morning and I just noticed it once again this evening. There’s no record of our shared users turning them on at those times and no footage is available.
