TL;DR: Signs of a problem include login alerts from a location you don't recognize, the device's activity log showing views or motion triggers you didn't initiate, or the camera physically moving or making sounds without your input. Use a unique, strong password for the camera's account, enable two-factor authentication in the manufacturer's app, review the account's login-activity log for unfamiliar access, and keep the device's firmware updated through the companion app.

What Usually Causes This
Most smart doorbell and camera compromises trace back to a reused password exposed in an unrelated data breach, since the credentials for the manufacturer's cloud account (not the device itself) are usually the weak point.
What to Do About It
Use a unique, strong password for the camera's account, enable two-factor authentication in the manufacturer's app, review the account's login-activity log for unfamiliar access, and keep the device's firmware updated through the companion app.

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.
