Power over Ethernet (PoE) Simplicity

You’ll enjoy a cleaner installation because each camera only needs one Ethernet cable for power and data. This reduces wire clutter and lets you place cameras where power outlets might not be convenient.

Smart AI Person Detection

You’ll get person detection on each camera, which helps reduce false alarms triggered by animals, cars, or moving foliage. That means fewer irrelevant alerts and easier monitoring of real security events.

Built-In Microphone for Audio

You’ll have audio recording capabilities built into each camera, giving you context in addition to video. This can be especially useful for identifying sounds or confirming what happened during an incident.

Pre-Installed 4TB Hard Drive

The included 4TB HDD saves you the hassle of buying and installing storage separately, and it provides plenty of space for continuous and motion-triggered recordings. You can expand storage up to 24TB by adding two 12TB drives, giving room for long-term retention if you need it.

Camera Design and Build

The mix of bullet and dome cameras gives you flexibility for different mounting locations and aesthetic preferences. Both types are weatherproof, so you can use them outdoors in a variety of conditions.

Bullet Cameras

You’ll find bullet cameras useful for targeted, longer-range coverage such as driveways or gates. Their form factor and IR array support clear night imaging up to about 100 ft.

Dome Cameras

You’ll likely prefer dome cameras for ceiling or soffit mounting where vandal resistance and a lower visual profile matter. They blend into environments and protect the lens from tampering or accidental contact.

Image Quality and Video Performance

You’ll get solid image quality for most surveillance tasks thanks to the 5MP camera sensors and the NVR’s ability to handle higher resolution channels. The system supports up to 12MP realtime recording capability on the NVR, offering flexibility if you later add compatible higher-resolution cameras.

Resolution and Field of View

You’ll benefit from 5MP resolution on each camera, paired with a 2.8mm lens that offers a wide field of view for general surveillance. This lens choice helps you capture broader scenes without requiring as many cameras.

Compression and Bandwidth Efficiency

You’ll find that H.265 compression reduces storage and bandwidth needs compared with older codecs like H.264. This efficient compression helps you preserve quality while storing more footage on the 4TB drive.

Night Vision and Low-Light Performance

You’ll have dependable night-time coverage thanks to 18 infrared LEDs and around 100 ft of IR distance for each camera. The combination of IR illumination and the camera sensor ensures recognizable images in low light conditions.

Infrared Range

You’ll be able to monitor larger yards, parking lots, and property perimeters at night with the ~100 ft IR distance. Keep in mind that dense fog, heavy rain, or obstacles can reduce effective IR performance.

Color in Low Light

You’ll still get color images during low-light conditions when ambient lighting is sufficient, but the cameras rely on IR for true darkness; in complete darkness, images will switch to black-and-white IR mode. Positioning cameras near light sources or using external lighting will give you better color detail at night.

Installation and Setup

You’ll appreciate how straightforward the plug-and-play PoE setup is: connect each camera to the NVR with a single Ethernet cable and your system is physically linked. Then use the mobile app and QR code to finish the remote access setup.
