Câmara de vigilância IP Reolink E331 — turret para interiores, 2880×1616, objetiva de 4 mm, 87,5° horizontal, WLAN, montagem no teto/mesa

Reolink E331 is an indoor turret IP security camera delivering high-resolution 2880×1616 (5MP) video with a fixed 4 mm lens and an 87.5° horizontal field of view. Designed for ceiling or desk placement, the E331 supports wireless (Wi‑Fi) connectivity and records at up to 20 fps using a 1/2.7" CMOS sensor. The camera provides motion detection, a tilt range of 0–50° for flexible framing, and a compact two-tone housing in white and black for unobtrusive indoor monitoring.

Advantages

The E331 offers increased image detail compared with lower-resolution models thanks to its 2880×1616 sensor and 5MP optics, which helps with clearer identification of faces and objects. Its F1.6 aperture improves low-light performance by admitting more light than standard lenses. Wireless connectivity and dual-band Wi‑Fi support simplify installation without running Ethernet, while motion detection and local microSD or NVR recording options provide versatile storage choices. The turret form factor and ceiling/desk mounting options allow flexible placement to cover different indoor layouts.

Suitable for

• Home monitoring of living rooms, nurseries and entryways
• Small office surveillance and reception areas
• Pet monitoring and activity tracking
• Short-term recording for events and motion-triggered clips

How to use

Place or mount the Reolink E331 on a ceiling or flat surface depending on the required view. Power the camera and follow the Reolink app setup to connect it to your Wi‑Fi network, complete initial positioning, and configure recording modes. Use the app to set motion detection sensitivity, enable two‑way audio, and select local storage or NVR/FTP/NAS destinations. Adjust the tilt within the 0–50° range to fine-tune the monitored area and test alerts to ensure notifications are delivered correctly.

Recommendations

For reliable motion detection and optimal coverage, mount the camera at a moderate height with a clear view of entry points and high-traffic zones. Use microSD or NVR storage for continuous or scheduled recording, and enable dual-band Wi‑Fi on the stronger frequency for stable streaming. When monitoring a nursery or sensitive area, enable privacy mode when needed to temporarily stop monitoring without disconnecting power.
