The REOLINK RLK8-520D4-5MP is a wired PoE (Power over Ethernet) home security system designed to offer homeowners and small business owners peace of mind through high-resolution video surveillance and advanced smart detection features. This review will take a detailed look at its build quality, installation process, performance, storage capacity, detection capabilities, and overall value to help you determine if it’s the right fit for your security needs.
Design and Build Quality
The system comes with four 5MP PoE IP cameras, each housed in a durable metal casing suitable for outdoor use. The design is sleek and professional, with a robust feel that reflects its weatherproof IP66 rating. This ensures the cameras can withstand a variety of environmental conditions, including rain, snow, and heat. The cameras are designed with fixed 80-degree viewing angles, balancing wide-area coverage with clarity.
The included NVR (Network Video Recorder) supports up to 8 channels, providing future scalability if additional cameras are needed. It has a compact yet solid build, with clearly labeled ports and a user-friendly interface.
Installation and Setup
One of the strongest points of the RLK8-520D4-5MP system is its Power over Ethernet capability. PoE simplifies installation by using a single Ethernet cable for both power and data transmission, eliminating the need for additional power adapters or outlets near the cameras. This is particularly helpful for placing cameras in hard-to-reach or outdoor areas.
The system includes everything needed for a DIY installation: Ethernet cables, mounting hardware, and detailed instructions. While the setup process is more hands-on than a wireless system, it’s relatively straightforward for users with basic technical know-how. Once the cameras are connected to the NVR and powered on, the system automatically detects them, making it easy to get up and running.
Video Quality and Performance
Each camera in the system captures video in 5MP Super HD (2560 x 1920 resolution), providing clear and detailed footage that surpasses standard 1080p cameras. This higher resolution allows for better facial recognition, license plate visibility, and overall scene clarity.
Night vision performance is impressive, thanks to the built-in infrared LEDs that provide visibility up to 100 feet in total darkness. The image remains sharp and usable, even in low-light conditions, with minimal noise or distortion.
The NVR supports 4K output, allowing users to view their surveillance footage on a 4K monitor for a more immersive experience. The interface is responsive, with options to view live feeds, playback recorded footage, customize detection settings, and manage storage.
Smart Detection Features
A standout feature of the RLK8-520D4-5MP is its smart detection technology. The system is capable of distinguishing between people, vehicles, and pets, significantly reducing the number of false alarms triggered by irrelevant motion, such as tree branches swaying or insects flying by the lens.
Customizable motion zones allow users to focus surveillance efforts on key areas, such as driveways or entrances, while ignoring others. Alerts can be configured to send push notifications or emails with snapshots or video clips, keeping users informed in real-time even when they are away from home.
Storage and Playback
The NVR comes pre-installed with a 2TB hard drive, which provides ample space for continuous 24/7 recording. Depending on the recording settings and the number of active cameras, this can provide several days to weeks of footage without needing to overwrite. Users can also set schedules or trigger recordings based on motion events to optimize storage use.
The system supports USB backup and remote access through the REOLINK app, making it easy to export footage or monitor the system while traveling. Playback controls are intuitive, with time-stamped recordings, event search, and timeline scrubbing.
Expandability and Compatibility
While the system includes four cameras, it supports up to eight channels, allowing room to grow. Additional REOLINK PoE cameras can be added easily. The system is also compatible with REOLINK’s software ecosystem, including desktop and mobile apps for both iOS and Android. This enables centralized monitoring across different devices and locations.
It’s worth noting that the system is designed to work best within the REOLINK ecosystem, so integration with third-party platforms or smart home assistants is somewhat limited. However, it does offer basic ONVIF compliance for users who wish to incorporate the cameras into a broader security network.
