Shopping in United States · USD. Local prices and listings only; confirm stock and the exact variant at the store.

The eufy SoloCam S340 records without a monthly fee (8 GB built in; HomeBase S380 optional). It lists at $199.99, so three years costs about $200. Power: solar + battery. The legacy specification-based estimate is about 30 ft by day and 30 ft at night across 135°; the interactive Planner uses a separate illustrative view, not an identification guarantee.

Reviewed recording configurations

1 exact US configuration, checked against official documentation (latest review: 2026-09-29). These are documentation reviews, not hardware tests. The Planner uses these same facts to show storage allowances, 3/5-year costs and what remains without a paid recording plan.

A local-storage label does not establish continuous recording, smart alerts, offline operation or cloud retention. “Not verified” means this review has not established that feature. Prices keep their own recorded offer dates.
