  • 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)

See in color all night long

There is typically an automatic shift from full color to black and white video at night with security cameras. This is not the case for your two LNB4321B bullet security cameras 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.
