4K Nocturnal bullet security cameras

Capture all details with 4K Ultra HD

The six Nocturnal cameras are equipped with an 8.51-megapixel (MP) image sensor. This powerful sensor is what makes the cameras capable of delivering crisp 4K Ultra HD video. With this sensor, you can capture all distinct details in the video, including unique facial features and zoom in on plate numbers of passing cars.

4K resolution image

Four times more powerful than standard 1080p

There is no arguing, these white Nocturnals are four times more powerful than any 1080p flagship camera on the market today. These Nocturnal cameras can deliver video content with 8.3 million pixels, breaking whatever preconception you have of a security camera. With this much detail in the content, you will have high-quality video with sharp and definitive lines, that distinctly identify objects in the video. With its zoom feature, you can enlarge a portion of the video without losing your mind by trying to decipher intelligible content in the footage.

zoom lens security camera

4× optical zoom security camera

Equipped with motorized varifocal lenses, these cameras have four times optical zoom capability, thus giving you more room to customize your field of view. You can also operate the zoom feature remotely through the Lorex Cloud app.

Color Night Vision footage
Infrared Night Vision

Say goodbye to grainy nighttime video for good. Nocturnal security cameras are equipped with powerful LED bulbs that emit infrared light in the camera's field of view. 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™)

For an added level of nighttime protection, Nocturnal security cameras can also capture color footage, thanks to our state-of-the art Color Night Vision (CNV) technology. CNV brings extra details to light, such as the color of a car, a person's clothes, and also provides better contrast for enhanced detection.

IR cut filter

Active mechanical lens filter

An Active Mechanical Lens Filter (otherwise known as an IR Cut Filter) prevents UV and infrared light rays from entering the lens during the day. This ensures that these types of lights won't cause any discolorations or distortions of the video. The filter will then automatically disengage at night, allowing the infrared light into the lens.

High Dynamic Range example

Enhanced security monitoring with HDR

These cameras use a High Dynamic Range (HDR) feature to automatically adjust the picture's brightness by finding the perfect balance between the brightness and darkest portions of the video. Using HDR results in optimized, highly-detailed security video in all sections of the frame.

3D digital noise reduction example

Increased clarity in low-light settings

These cameras use 3D-Digital Noise Reduction (DNR) to filter out digital noise caused by motion blur. This technology ensures clean, accurate video with exceptional clarity and sharpness.

4K nocturnal weatherproof security camera

All-weather security camera

With the highest environmental rating of IP67, these cameras are designed for outdoor use and monitoring. These cameras can withstand heavy rain and other harsh weather conditions.

Plug-and-play simplicity with Power over Ethernet technology

PoE technology for simple plug-and-play installation

Power-over-Ethernet (PoE) technology is an all-in-one solution that cuts cost and installation time. A single cable run between your NVR and IP camera provides both power and video transmission so you don't have to install your camera near a plug.

security certified NVR hard drive

Reliable security-grade hard drive preinstalled

A 3TB security grade hard drive (expandable up to 2 × 8TB) 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.

HEVC logo


The cameras and the NVR both use HEVC compression technology. HEVC is particularly handy in this security system as it compresses large 4K footages without losing quality. It keeps your 4K footage without the 4K file sizes. It also allows you to watch the highest quality security footage while you are away from your home or business without large data transfers.

4K vs 1080p pixels

Area search

Find what you are looking for quickly with Lorex's Area Search. Select an area of interest and automatically playback any video footage showing scene changes in that area. Ideal for doorways, drive ways, etc.

Regional motion zones for motion detection

Regional motion zones

There may be certain sections in the camera's field of view that you want to focus more on, such as the front door, garage or backyard. Create up to four custom motion zones for each camera and adjust the motion sensitivity to best suit your needs. That way, even the slightest movement near important areas, such as an entranceway, will trigger the camera and create a motion event, but inanimate objects like trees or bushes would need more significant movement in order to set off the motion detection.

Privacy masking NVR

Privacy masking

If there are certain areas in the camera's field of view that you do not want recorded, you can block those sections using privacy masking. Simply use the NVR to outline the areas you want blacked out with a square or rectangle.

Quick setup guide

1. 4K (8MP) IP cameras are required to take advantage of 4K recording.
2. Advanced Person/Vehicle Motion Detection can be enabled on up to 8 channels at once. General motion detection will still be available on all remaining channels.
3. Accuracy of Advanced Person and Vehicle Motion Detection will be influenced by multiple factors, such as the object's distance from the camera, the size of the object, and the height and angle of the camera. Night vision will also impact the accuracy of detection.
4. Controlling certain features in your security system requires a compatible smart device. Availability and performance of certain features and services are smart device dependent and may not be available in all areas or networks. For compatibility, features, and instructions visit
5. Accessing your security system remotely requires a high-speed Internet connection. Ensure your NVR has a wired connection to a router (not included). A minimum upload speed of 5Mbps is recommended for reasonable video performance. Up to 3 devices may connect to the system at the same time.
