## Long description

This battery-powered wire-free security camera delivers reliable protection for your property with 4K (8MP) resolution and pan-tilt capability for a complete 360° view. Dual-band 2.4/5GHz Wi‑Fi ensures a more stable connection, while person, vehicle and motion detection helps reduce false alarms. Built-in color night vision, two-way audio, siren and spotlights provide flexible active deterrence. Recordings can be stored on a microSD card (up to 128 GB) or in the cloud, and remote access is available via the Reolink app and client without monthly fees.
Advantages
The camera offers 4K image quality combined with pan-tilt rotation to monitor every corner. Dual-band Wi‑Fi improves connection stability for live viewing and notifications. Smart detection differentiates people, vehicles and general motion to deliver more relevant alerts. Two-way audio and dual warning (siren plus spotlights) enable immediate interaction and deterrence. Multiple storage options provide flexibility for local or cloud recording, and mobile/PC apps allow remote control and viewing.
