Your first camera is free.
Add more for $30/year each.

Yes. One camera runs free forever, with full recording, live view, on-device AI detection, remote access, and the iPhone app. No account needed, and it even works completely offline. You only pay when you add a second camera.

Additional cameras are $30/year each, billed through Stripe as a single subscription whose quantity equals the number of paid cameras you run. Add or remove cameras anytime and your subscription adjusts. If a payment lapses, Sentinel keeps your cameras running through a 30-day offline grace period before falling back to your free camera.

A flat $4.99/month (not per camera) that turns person alerts into Ring-style natural-language summaries like “a person in a red shirt carrying a bag, walking toward the door,” powered by Claude Haiku vision, up to 1,000 described alerts per month. Every other detection type runs on-device at no cost.

No. Video, recordings, and on-device AI all stay on your Mac. The only outbound calls are license validation for paid cameras and, only if you enable it, the optional AI Descriptions add-on, which sends a single downscaled frame to generate a one-line summary. Your free camera can run entirely offline.

Not for your free camera. To license additional cameras you create a free Sentinel account so your subscription and camera entitlements stay in sync across reinstalls and machines.

Add cameras from the Mac app's Upgrade screen, and the new limit takes effect immediately. Remove a camera and your next bill reflects the lower count. Manage or cancel the subscription anytime from the Stripe billing portal; cancellation stops future renewals and you keep your free camera.
