Performance and Features
Image Quality and Panoramic View
The camera’s standout performance feature is its 16MP ultra-high-definition resolution, generated by stitching the video from two 4K sensors. The manufacturer states this is achieved through dual-image stitching algorithms and a 4-core system-on-chip (SoC) to create a 180-degree panoramic view with less distortion and fewer blind spots. The fixed F1.6 aperture and 1/2.7-inch CMOS sensor are designed for greater light intake, which is critical for its low-light performance. The default video output is 7680×2160 at 20 frames per second, providing a highly detailed, widescreen image format.
Night Vision and Low-Light Capability
For nighttime surveillance, the camera offers two modes. The primary mode is color night vision, activated by its built-in spotlights, which have a specified output of 560 lumens. When color mode is not required or preferred, it can switch to infrared night vision using its six 850nm LEDs, providing illumination up to 100 feet (approximately 30 meters). The IR-cut filter automatically switches between day and night modes.
Smart Detection and Alerts
Intelligence is a major component of its performance. The camera uses AI to accurately detect people, vehicles, and animals, filtering out motion from other objects like moving foliage to reduce false alarms. Upon detection, it can send instant push or email notifications to the user. Furthermore, it includes deterrent features: motion-triggered spotlights and a customizable siren can be activated to warn off intruders. The “Motion Track” feature is designed to display the complete path of a detected target in a single composite image, potentially saving review time.
Connectivity and Power
This is a wired camera utilizing Power over Ethernet (PoE) technology. A single Ethernet cable connected to a PoE source (like an NVR, switch, or injector) provides both network connectivity and power, simplifying installation. It features a 10/100 Mbps RJ45 port. The manufacturer notes that a PoE NVR, switch, injector, or DC power adapter is not included in the box.

Software and User Experience
Control and access are managed through the Reolink App or Client software. Features include remote live viewing, custom motion zones, and smart playback at speeds up to 16x. The two-way audio function allows for communication through the camera. A notable software feature is “Time Lapse,” which can condense long-term events, like a full day, into a short video for easy observation. The system supports multi-user access, allowing several people to view feeds simultaneously.
Setup, Support and Ownership
Setup is centered on the PoE connection. Users must supply their own PoE source, as it is not bundled. Mounting is described as easy with the provided bracket. For recording, users can choose a microSD card (up to 512GB), a compatible Reolink NVR, or both. Critical ownership information involves NVR compatibility: for full 16MP support, a Reolink NVR with hardware versions Hw_N5MB01, Hw_N6MB01, or Hw_N7MB01 with the latest firmware is required.
