TL;DR: Signs of concern include the monitor's camera moving on its own, unfamiliar sounds coming from the speaker, or the companion app showing a login session from a device or location you don't recognize. Set a unique, strong password for the monitor's account, enable two-factor authentication if the app supports it, keep the device firmware updated, and review the account's active-sessions list periodically for anything unfamiliar.

What Usually Causes This
As with other smart cameras, the weak point is almost always the account password rather than the device itself — a reused or weak password on the manufacturer's cloud account is the most common entry point.
What to Do About It
Set a unique, strong password for the monitor's account, enable two-factor authentication if the app supports it, keep the device firmware updated, and review the account's active-sessions list periodically for anything unfamiliar.

Should I be worried if I only see one sign?
One sign alone (like a slower device) is usually not cause for alarm — most single symptoms have mundane explanations. Multiple signs together, especially unexpected data usage or unfamiliar apps, are worth investigating.
