Reolink NVS8-8MD84TB 4K Security System with 8 PoE Dome Cameras, 4TB NVR & 12-Camera Expansion

Monitor your home or business with the Reolink NVS8-8MD84TB security system. Eight wired PoE dome cameras capture 4K video at up to 20 frames per second, while the included NVR stores recordings locally on a preinstalled 4TB hard drive without a required recording subscription.

Person, vehicle, and animal detection helps filter motion alerts. Perimeter protection adds line-crossing, zone-intrusion, and loitering notifications, while heat mapping helps visualize activity patterns. Expand the system with up to four compatible Reolink battery-powered Wi-Fi cameras for a total of 12 cameras.

Key Features

• Eight 4K Dome Cameras: Capture 8MP video at 3840 × 2160 resolution and up to 20 fps.

• 4TB Local Storage: A preinstalled hard drive supports recording without a required subscription.

• Smart Object Detection: Identifies people, vehicles, and animals to help reduce unwanted alerts.

• Perimeter Protection: Configure line-crossing, zone-intrusion, and zone-loitering rules for selected areas.

• Activity Heat Mapping: Displays motion patterns as a color-coded overlay to help identify frequently used areas.

• Two Night Vision Options: Use spotlights for color footage or infrared night vision for visibility up to 100 feet.

• Two-Way Audio: Built-in microphones and speakers support listening and speaking through the system.

• Spotlights and Sirens: Configure motion-triggered responses or activate deterrent features through supported controls.

• IP67-Rated Cameras: Metal housings provide weather protection for indoor and outdoor installation.

Why It Stands Out

This system combines eight wired 4K cameras with centralized local storage and room for compatible battery-camera expansion. Perimeter rules and heat mapping offer additional ways to review activity beyond basic motion alerts.

FAQ

Are the eight included cameras wireless?
No. They connect to the NVR using Ethernet cables that carry both power and video.

How does the system expand to 12 cameras?
It supports the eight PoE cameras plus up to four compatible Reolink battery-powered Wi-Fi cameras. Additional cameras are sold separately; confirm model and firmware compatibility before purchasing.

Is a monthly subscription required?
No subscription is required for recording to the included NVR hard drive.

Will it keep recording if the internet goes out?
The included wired cameras can continue recording locally while the NVR and cameras remain powered and connected. Remote access and internet notifications require an internet connection.

Can I view footage on my phone or TV?
Yes. Use the Reolink App for remote access, or connect a compatible display through HDMI or VGA. An HDMI cable is included.

What does heat mapping show?
It uses a color-coded overlay to show where motion occurs more or less frequently. It visualizes activity rather than measuring temperature.

Does the 100-foot night vision range apply to color footage?
The supplied description associates the 100-foot range with infrared night vision. Color night vision uses the built-in spotlight.

How long will the 4TB drive retain footage?
Retention depends on camera count, bitrate, resolution, frame rate, and recording schedule. A fixed recording duration is not guaranteed.
