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° angle lens is perfect for large outdoor or indoor spaces.

PoE 2K IP security camera

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)

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

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.

Location: VA

Just received system from Lorex and in the process of bench testing it. Cameras are exceeding good; high resolution and excellent night vision. Had some problems as system did not want to work with HDMI input, so used the VGA port instead. Tech support said issue was probably display resolution, but have not pursued that as I am very satisfied with VGA. Essentially a plug and play system. Waiting for cooler weather so that I can install the cameras. Documentation was poor, but really did not need it.
