How to choose

Before you buy

01 · Where will you put it?

Any pick works plugged into a wall outlet near eye level. For a tight corner or shelf, go small with the Blink Mini or Wyze Cam v4; for a wide room from a high shelf, the Eufy C220's pan/tilt covers more ground.

02 · What are you watching for?

Pets while you're at work suit the Wyze Cam v4 with AI pet detection. For a sleeping baby, look at a dedicated monitor with crying detection instead; for package thieves, add a video doorbell.

03 · Subscription or no subscription?

To avoid monthly fees, pair the Tapo C100 or Kasa KC100 with a microSD card for continuous local recording. If you'd rather have cloud-stored events, Wyze with Cam Plus at $3/mo is the cheapest cloud option.

04 · How private do you need it?

Mainstream users are fine with any pick. If you're skeptical of cloud cameras, choose the Eufy in local-only mode or the Tapo in a microSD-only configuration.
