This 4K security system from Lorex is as versatile as it is powerful. It starts with our top-of-the-line 32-channel N881 Series 4K network video recorder (NVR) and a 16-channel PoE switch. It then combines the power of three different types of security cameras, two of which come from our exclusive all-black Nocturnal line-up. Each of these specialized security cameras offer unique feature sets that will help protect your entire property, such as 4K and 2K resolutions and listen-in audio functionality. This system has room to grow as well. Space for eight additional IP security cameras (including 4K security cameras) is there for you if you need.

nocturnal 4K resolution security camera

HD security monitoring

Leave nothing to question. The 8MP (megapixel) image sensor at the core of the included bullet security cameras is capable of producing vivid 4K UltraHD security footage. Also in this system is eight 4MP (LND4750AB) dome security cameras that can record high-quality 2K SuperHD resolution video.

4K chart

What are 4K and 2K resolutions?

Your 4K resolution security cameras contain 4× the amount of pixels as a 1080p security camera. Instead of recording at a pixel ratio of 1920 × 1080 (a total of 2,073,600 pixels), your 4K camera can record at a pixel ratio of 3840 x 2160 (a total of 8,294,400 pixels). Similarly, your 2K cameras contain approximately 2× the number of pixels as 1080p cameras. This higher pixel amount will provide you with exceptional video quality, with clear details and sharp outlines. It will also allow for much better digital enhancing. This means that when you spot something in your footage that you need to zoom in on, specific details, such as facial features, will remain visible for longer as you digitally zoom in further and further into the image.

Person Vehicle Artifical Intelligence AI detection security camera

Person and vehicle smart motion detection

The bullet cameras included here come with smart person and vehicle detection that helps identify more important objects that enter the their field of view. Thanks to this innovative feature, you will only get a push notification whenever a person or vehicle is detected on your property. This effectively reduces the number of unwanted false alerts caused by moving branches or animals.

Color Night Vision footage
Infrared Night Vision

See further into the dark than ever before. Nocturnal security cameras come with high powered infrared LEDs that flood the scene in front of the camera with infrared lighting. Invisible to the naked eye, but not to the camera, this infrared lighting will allow your security camera to see in complete darkness.

Color Night Vision (CNV™)

Add external lights around your nocturnal security camera to utilize our revolutionary Color Night Vision technology. With CNV, you'll be able to capture a whole new level of details, such as the color of a car or the color of a person's clothes, which may prove invaluable if needed for evidence.

HDR security camera

See the whole picture with HDR

All security cameras in this system use HDR (High Dynamic Range) technology to help you see details in all areas of the video, regardless of lighting conditions. It works by automatically adjusting the picture's brightness levels in both dark and bright areas. This ensures that no part of the video is too over-exposed or too dark to see the details you need.

DNR security camera

Enhanced clarity and sharpness

Every security camera in this system uses DNR (Digital Noise Reduction) to remove any excessive noise / grain in low-light settings. This will deliver better clarity, sharpness, and improved motion detection. It will also reduce video file sizes as well.

Nocturnal audio dome security camera

Expanded coverage with built-in microphone

A built-in microphone within your eight 2K and eight 4K Nocturnal dome security cameras allows for listen-in audio recording.* Audio monitoring can provide you with additional information (such as voices), which could prove to be invaluable should an intrusion or event occur on your property. Audio can also help you interpret events, even if the action takes place away from the camera's field of view.

* Please note, audio recording without consent is illegal in certain jurisdictions. Lorex Corporation assumes no liability for use of its products that do not conform with local laws.
