2K (4 megapixel) IP Camera with Color Night Vision

The LNB4321B network bullet security camera will bring a whole new level of detail and clarity to your home or business surveillance needs. This Super HD security camera is capable of recording double the resolution of 1080p thanks to the 4 megapixel image sensor at its core. It also comes with our innovative Color Night Vision (CNV) feature that will continue to deliver full-color video in low-light conditions. Leave nothing to the imagination and gain that crucial peace-of-mind you need with this top-of-the-line 2K security camera.

2K resolution video clarity

This 4mp security camera is capable of recording a 2K pixel resolution of 2688 x 1520 at 20 frames-per-second (FPS). This heightened resolution will provide you with stunningly detailed images and allow for greater digital zooms so you can see further into the distance. This security camera also uses a True High Dynamic Range (HDR) feature that will help reveal details in extremely bright and dark areas of the video. A wide 83 degree angle lens is perfect for large outdoor or indoor spaces.

Easy PoE installation

Your security camera will be up and running in no time thanks to innovative Power-over-Ethernet (PoE) technology. Using this technology, this camera only needs a single Cat5e ethernet cable to connect it to a compatible NVR. This cable provides:

  • Video transmission
  • Power to the camera
  • A stable network connection
  • Installation flexibility up to 300ft* (as the camera does not need to be plugged into a nearby power source)

Full-color video, even at night

With most security cameras there is usually an automatic shift from full color to black and white when lighting conditions change at night. This is not the case for the LNB4321B bullet security camera. It features our revolutionary Color Night Vision (CNV) technology. This feature will:

  • Produce full-color video, even in low-light conditions*
  • Provide a further level of detail (the color of clothes or cars, for example)
  • Add increased contrast for easier detection and recognition of people and objects

*Please note that ambient lighting is needed for full-color night vision. The image will typically switch to black and white infrared in total darkness to ensure maximum quality night vision.

Perfect for the outdoors

The durable LNB4321B security camera is manufactured to be fully weatherproof. Rated IP66, your 2K security camera is suitable for both indoor and outdoor installation. It is able to withstand the most unforgiving climates so you can count on all-season security monitoring that never stops working. With versatile ceiling or wall mounting options, the LNB4321B security camera can be safely placed wherever you need it most.
