LNB8921BW nocturnal 4K resolution security camera
 

2K security monitoring

Leave nothing to question. The 4MP (megapixel) image sensor at the core of this security camera is capable of producing vivid 2K superHD security footage. It also comes with a wide 120° angle lens that is perfect for monitoring doorways or open areas.

4K nocturnal security camera resolution chart

2K vs 1080p resolution

This 2K resolution security camera contains double 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, this nocturnal audio dome records a pixel ratio of 2688 × 1520 - a total of 4,085,760 pixels. One of the main benefits of a higher pixel count is the quality of the digital zooms when reviewing footage.

 
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.

 
 
electronic shutter eShutter nocturnal security camera

eShutter™

The higher the shutter speed, the sharper the video. A high shutter speed, however, requires a lot of light. Thankfully, this camera's eShutter™ (electronic shutter) figures out this balance for you, so you will always have optimized lighting with the least amount of motion blur.

IR cut filter gif nocturnal security camera

Active mechanical lens filter

An Active Mechanical Lens Filter, otherwise known as the IR Cut Filter, is used by this camera to prevent UV and infrared rays from entering the lens during the day. Without it, the coloring of the video would not be accurate. This lens filter will then automatically disengage at night to allow the infrared light in.

30 FPS nocturnal 4K security camera

Real-time 30FPS recording rate

This security camera is capable of recording 2K security footage at 30 frames-per-second (FPS). 30 FPS will provide exceptionally smooth on-screen movement and provide you with more frames to choose from when reviewing footage.

HDR nocturnal security camera

Enhanced security monitoring with HDR

This security camera uses HDR (High Dynamic Range) technology to ensure that you capture the most important details, regardless of lighting conditions. Dynamic range is measured as the difference between the brightest point and the darkest point of the video. HDR technology uses this difference to automatically adjust the picture's brightness, resulting in optimized, highly-detailed security video.

DNR nocturnal 4K security camera

Increased clarity in low-light situations

This camera uses 3D-DNR (Digital Noise Reduction) technology to filter out digital noise from low-light scenes, as well as any noise caused by motion. By eliminating this graininess, your camera will deliver a cleaner, more accurate image with better clarity, sharpness, and improved motion detection.

security camera with auto white balance AWB

Auto white balance

An auto white balance feature automatically adjusts the color settings so that white areas in real life will be reproduced as white in your footage. This will then ensure that all other colors will be accurate. White balance customization is also available through the NVR as well for additional levels of white balance control to suit your needs.

HEVC logo H.265 security camera model LNB8921BW

HEVC / H.265 compression

High Efficiency Video Compression (HEVC or H.265) compression technology is used by this camera to compress video file sizes without any noticeable difference in quality. When compared to the previous compression technology, H.264, HEVC can compress data up 40% more with the same level of quality. Please note that an NVR capable of receiving this type of compression is necessary to utilize this feature.

Camera Features

Nocturnal audio dome security camera

Expanded coverage with built-in microphone

A built-in microphone within this security camera 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 does not conform with local laws.

Installation and Customization

easy to install IP security camera

Easy PoE installation

Connect this audio security camera to an NVR with a single Cat5e (or above) ethernet cable. This cable provides video transmission, audio transmission, power to the camera, and a stable network connection all at once. Furthermore, the lack of power cable allows you to install this security camera virtually anywhere you need it (up to 300ft), since the camera does not need to be plugged into a nearby power source. For more distance, please see our selection of PoE switches.

Regional motion zones security camera

Regional motion zones

Create up to four different regional motion zones through your NVR. This allows you to adjust the sensitivity (the amount of movement required to register that movement) and the threshold (how much movement is required before creating a motion "event") at four different levels. This means that more important areas, such as a doorway, can be adjusted so that any movement at all will trigger recording (or create a motion event), while other sections of the frame, like a bush, would need a much higher level of motion.

Privacy masking security camera

Privacy masking

If there are some elements within your camera's field of view (such as inside windows) that you do not wish to record, then you can use your NVR to mask out these sections by drawing a square or rectangle over them.

nocturnal security camera custom video orientation

Custom video orientation

This security camera can be installed on the ceiling or on the side of walls without worrying about how the video feed will look. You can easily change the visual orientation with the NVR after installation. The video feed can be rotated 90°, 180°, and 270°, and can also be flipped upside down and mirrored.
