See the details you need with Super HD resolution

You've never seen security footage like this before. Don't let specific details like facial features or license plate numbers elude you with the world-class feature set offered by your four IP cameras:

  • 2K pixel resolution (2688 x 1520) at 20 frames-per-second (FPS)
  • Greater digital zooms so you can see details further into the distance
  • True High Dynamic Range (HDR) will help reveal details in extremely bright and dark areas of the video
  • Wide 83° angle lenses that are perfect for large outdoor or indoor spaces

How to install IP security cameras?

Experience true plug-and-play installation simplicity between the NVR and your cameras by connecting each of them with a single Cat5e Ethernet cable. 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)

*Click here to purchase extension cables. You can also incorporate a PoE switch if more distance is needed.

Top-of-the-line night vision - in color

There's no shift from full-color to black and white video at night with your four LNB4321B bullet security cameras. This is thanks to 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.

Great camera system....easy to use, high quality images during day and night. Was able to get 8 cameras installed in just a few hours. Needed to buy longer cables (100ft), because the 60ft cables included were not long enough for some of the install locations. Aside from that, I would recommend.
