Reolink 5MP Wi-Fi PT Indoor Security Camera with Auto Tracking – E331

Reolink E331 is a 5MP Wi-Fi PT indoor security camera designed for home monitoring, baby monitoring, and pet monitoring. It offers 2880 × 1616 resolution, 355° pan, 50° tilt, smart detection, auto tracking, and crying detection, making it suitable for whole-room indoor coverage.

The camera uses a 1/2.7″ CMOS sensor with a 4mm lens and F1.6 aperture. Reolink states that the wider aperture helps deliver brighter images in low-light indoor conditions. For night use, the E331 includes infrared night vision up to 12 metres and an IR-cut filter with auto switching.

For connectivity, the E331 supports dual-band 2.4GHz and 5GHz Wi-Fi with Wi-Fi 6 readiness, plus Bluetooth support. It also includes two-way audio with a built-in microphone and speaker, so users can listen and talk through the camera remotely.

The camera supports microSD cards up to 512GB, Reolink NVR, Reolink Home Hub series, and FTP/NAS backup.
