Powerful HD recording and 4K capability

Ultra HD 4K resolution recording

This NVR is a powerhouse. With 4K resolution, nothing is left to the imagination. The higher number of pixels (3840 × 2160 as opposed to 1920 × 1080) gives your video footage superior detail and definition and clearly outlines the distinct features of objects that appear on camera while maintaining realistic color representation. Having more than 8 million pixels also prevents the distortion or blurring of the image when using the digital zoom.

Area Search

Find what you are looking for quickly with Lorex's Area Search. Select an area of interest to easily playback any video footage showing scene changes in that area or filter by specific motion events to view only the type of motion (ie. Person/Vehicle) that you are interested in viewing. Ideal for doorways, driveways, etc.

N881 Lorex Cloud App

Lorex Cloud app for smartphones and tablets

Connect this NVR to the Lorex Cloud™ app for easy remote monitoring and more. This easy-to-use app allows you to view live and recorded video from your security cameras on your smartphone or tablet for peace of mind no matter where in the world you are. This app will also enable convenient push notifications for motion-triggered events so you can always be in-the-know.

NVR supports all IP cameras

Supports a full range of IP cameras

This NVR is compatible with the Lorex full range of IP security cameras. This includes all 1MP, 2MP, 3MP, 4MP, 5MP, 6MP, 7MP, and 8MP IP cameras.



Real-time 30FPS streaming rate

View live footage in up to 30fps.* This high frame rate ensures that you don't miss the best moments.

*Not all 8MP (4K) IP security cameras are capable of streaming 4K video at 30fps. Please see your camera's specifications for its maximum frame rate.

easy installation with PoE (Power over Ethernet technology)

Plug-and-play installation via PoE

Connect IP cameras to the integrated power-over-ethernet (PoE) ports for a truly plug-and-play surveillance experience. Each camera only requires a single ethernet cable to connect it to the NVR thanks to PoE technology. Simply insert one side of the ethernet cable to the camera and the other to the NVR - and your cameras will be ready. This all-in-one cable provides both powers to the camera and video transmission up to 300ft / 91m. This means that you do not need to install your security cameras to a power outlet nearby.

Audio NVR via ethernet

Supports audio on every channel

The N881B Series NVR supports audio on every channel with no secondary connections required. Audio is transmitted to the NVR over the same Cat5e/Cat6 Ethernet cable that connects your camera to the NVR. So all you need is a Lorex camera that supports listen-in audio. Audio enabled cameras can enhance your security coverage by providing you with more evidence (such as voices) and can expand your security coverage beyond the camera's field of view (FOV).

free automatic software updates

Over the Internet Updates

This NVR will automatically update its firmware to the latest available version as long as it is connected to the internet. These free updates will always make sure that your NVR is up-to-date.

3TB security hard drive

Reliable security-grade hard drive preinstalled

A 3TB security-grade hard drive (expandable up to 2 × 10TB) comes preinstalled within this NVR. Designed to meet the high workload demands of continuous security monitoring, this heavy-duty hard drive can reliably record weeks (even months) of footage without taking a break. All recorded footage is then safely stored on the hard drive where only you can access it, so there are no surprise fees or monthly cloud subscriptions.

NVR overwrite hard drive

Automatic hard drive management

You won't have to lift a finger as the hard drive within the N881B Series NVR becomes full. It is programmed to automatically overwrite the oldest footage with the newest.

Two storage bays

This NVR comes with two separate hard drive bays. Each of these can be upgraded with a hard drive up to 10TB, giving you the potential for a total of 20TB's of storage space. You can also use the second hard drive to record videos in parallel with the primary hard drive. This way, the footage is automatically backed up if the recording hard drive fails

NVR multiple recording modes - continuous recording scheduled recording motion recording

Multiple Recording Modes

Customize this NVR's recording settings to fit your needs. It can record footage continuously, during scheduled times, or only when movement is detected. If you wish to only record motion events, there is no need to worry about missing those first vital moments. This NVR includes a pre-recording function that goes back to record the five seconds before the motion was even detected. Most importantly, all of these recording modes can be customized on a camera to camera bases.


Up to 40% More Storage Capacity

The N881B Series NVR is able to receive HEVC (High-Efficiency Video Encoding) or H.265 video compression files. This feature can save you up to 40% more space when compared to H.264 Advanced Video Coding. So go ahead and add one of Lorex's new line of 4K Security Cameras to your security system. They come equipped with HEVC compression capabilities, which allows you to receive 4x the resolution of 1080p without the large 4K file sizes.


watch dog and auto-revovery NVR

Auto-recovery after power failures

There is no need to worry about your NVR if there is a power failure. It will automatically reboot and start recording again within minutes of regaining power. This NVR also includes a Watchdog feature that continuously monitors the system for potential system errors. If a critical error is ever detected, Watchdog will automatically restart the NVR and start recording again. This restart will help ensure system stability, keep your cameras recording, and prevent future system failures.

NVR with IPv6

IPv6 ready

Your N881B Series NVR supports Internet Protocol version 6 (IPv6), the next generation of the IP address standard. This standard, compared to IPv4, will support 340 trillion, trillion, trillion IP addresses! Eventually, IPv6 will replace IPv4 altogether, but you won't have to worry as your NVR has been engineered to support both types of IP addresses.

with or without internet

With or without the internet

This NVR can be used without being connected to the internet. This means that your data can only be accessed directly from your NVR. However, an internet connection is required to enable remote viewing, motion push notifications, and to download the latest firmware updates.
