IP security camera Reolink E540-B 5MP outdoor Wi‑Fi, 2560x1920, 355° pan, 0–50° tilt, IP65, MicroSD up to 256 GB

The Reolink E Series E540 outdoor PTZ security camera combines compact design with smart detection to monitor people, vehicles and animals. It offers 355° pan, 50° tilt, 3× optical zoom and automatic left-right rotation for continuous tracking of moving targets. Dual-band Wi‑Fi (2.4GHz/5GHz) ensures a stable wireless connection, while 5MP (2K+) Super HD and color night vision deliver clear, full-color images day and night.

Advantages

The camera provides accurate person, vehicle and motion detection with configurable alerts. Pan-tilt and auto-tracking follow detected targets so important events are not missed. Three-times optical zoom reveals distant details without image degradation. Dual-band Wi‑Fi reduces connection interruptions for smoother live view. Color night vision and built-in spotlights improve nighttime visibility, and a siren adds an audible deterrent. Multiple storage options (microSD up to 256GB, NVR and cloud) offer flexible recording choices, and Google voice control enables hands-free access.

Recommendations

For best performance, mount the camera at a height that provides unobstructed view of driveways or entry points, ensure a strong dual-band Wi‑Fi signal, and format the microSD card in the Reolink app before first use. Adjust detection zones and sensitivity to reduce false alerts from background motion.
