Stick up Cam Randomly Recording?

I’m not sure if the stick up cams periodically record, but I had my devices set on Home mode (no recording Or detecting motion) and my living room stick up cam’s blue light came on. This was at about 3 AM, and it was a solid blue light. I was weirded out by it, as I didn’t know what it meant. I wasn’t in the Ring app live viewing. I currently do not share my devices with another user. Was it recording? As I went to check the app, the blue light went away and there was no history of a recording or live view. What did the solid blue light mean? It stayed on for maybe 30 seconds or less. Thanks!
