IP security bullet camera Reolink E340 8MP, 4K (3480×2160), PoE/2.4/5 GHz Wi‑Fi, microSD, IP67, 30 fps

Reolink E340 is an IP bullet security camera delivering up to 8MP (3480×2160) resolution at 30 fps. The camera comes in a metal housing with IP67 protection for outdoor and indoor use and supports wall or ceiling mounting. Network connectivity includes PoE (IEEE 802.3af), RJ-45 Fast Ethernet and dual-band Wi‑Fi (2.4 GHz / 5 GHz). Local storage is available via microSD card and the device supports smartphone and PC platforms.

Advantages

The camera offers high-resolution 4K-capable imaging with progressive CMOS sensor, 3D noise reduction and multiple image-enhancement features (WDR, BLC, HLC). Pan and tilt control (355° pan, 0–90° tilt) enable broad coverage, while 12 m night vision and day/night mode ensure continuous monitoring. Security and remote access are supported via HTTPS, WPA-PSK/WPA2-PSK, IP address filtering and password protection. Power options include PoE and DC 5V 2A.

How to use

Mount the Reolink E340 on a wall or ceiling using appropriate fasteners for the mounting surface. Connect power via PoE-enabled switch or DC 5V 2A adapter and attach the Ethernet cable for wired network access or configure Wi‑Fi (2.4/5 GHz) through the camera app. Insert a microSD card if local recording is required. Use the Reolink app or web interface to perform initial setup, configure network settings, set recording schedules, enable motion detection, adjust image parameters and control pan/tilt positions.

Recommendations

For reliable outdoor operation, install the camera under an overhang or use a weather-protected junction box; test night-viewing coverage after installation and set motion detection sensitivity to reduce false alarms. Regularly update firmware and secure the device with a strong password and HTTPS access.
