Nocturnal bullet and dome security cameras with 4K resolution recording

8MP security cameras

Generally speaking, security cameras are meant to capture important evidence should something happen on your property. That is why every Nocturnal security camera in this system contains an 8.51 MP image sensor that is capable of recording 4K resolution video. This sensor will provide you with exceptionally sharp video that will give you the best chance to capture the distinct details that you need.

4K resolution image

The 4K difference

A 4K camera records over six million more pixels than a 1080p security camera. That's 4× the amount of pixels! With this higher pixel count, you can expect a much higher quality of video, with sharp definitive lines that distinctly outline every object and feature. Another benefit of a 4K security camera is that details will remain legible for longer as you digitally zoom in to your footage. This makes 4K resolution especially important for security purposes.

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

It is important for a security camera to replicate colors as accurately as possible. Thankfully, there is an active mechanical lens filter, or an IR cut filter, that blocks the infrared lights emitted by your cameras from entering the lens during the day. This ensures that this type of light does not discolor the video. This filter will then automatically disengage when night falls to allow the infrared light back in.

HHigh Dynamic Range example

See the details you need in all lighting conditions

All of the included security cameras use an HDR (High Dynamic Range) feature that works to ensure that you can see clear details in all sections of the video, regardless of lighting conditions. This feature will automatically adjust the brightness of the video in both bright and dark areas of the video so you will always see the details you need.

3D digital noise reduction example

Clean video with DNR

Both sets of cameras use 3D-DNR (Digital Noise Reduction) technology to filter out noise / grain from scenes with low-light. It will also do its best to remove any noise caused by motion. This will provide a cleaner, more accurate image with better clarity, sharpness, and improved motion detection. It will also reduce video file sizes as well, giving you greater disc space for storage.

audio security camera

Expand your security coverage with listen-in audio

The listen-in audio capability of your dome security cameras will add a further layer of security coverage.* This will provide additional details (such as voices) and help detect and interpret events (even if they occur off-screen).

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

zoom lens security camera

Quick setup guide

1. 4K (8MP) IP cameras are required to take advantage of 4K recording.
2. 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.
3. 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. For the latest list of supported apps and devices, please visit
4. Compatible with certain Lorex IP cameras only. For a list of compatible cameras please visit
5. HDMI output supports 4K HD for high definition multi-channel live or recorded video viewing. Image quality and resolution is dependent on the type of camera connected to the NVR, as well as TV/monitor resolution.
