The LNB3373SB bullet IP security camera will bring a new level of clarity and detail to your home or business security monitoring. It features 2K (3 megapixel) video resolution, top-of-the-line night vision, and an integrated motorized varifocal lens for remote field of view customization. This security camera uses Power-over-Ethernet (PoE) technology for a simple, hassle-free plug-and-play installation.

3x optical zoom security camera

The LNB3373SB security camera contains a 3x optical zoom lens. Otherwise known as a “motorized varifocal lens,” this camera can zoom in and out to suit your security purposes. Choose to zoom in for a narrow field of view (33 degree ), zoom all the way out for maximum coverage (93 degree ), or anywhere in between. This feature makes this camera extremely versatile. It is perfect for both close-up monitoring (cash register or a doorway) and large area monitoring (like a backyard or parking lot). Best of all, you can make these adjustments easily with your Lorex NVR or a connected mobile device.

Plug-and-play installation via PoE

The LNB3373SB security camera has a built-in Power-over-Ethernet (PoE) port that makes for a straightforward installation. Simply connect the camera to the NVR with a single ethernet cable. This all-in-one cable provides both power and video transmission up to 300ft / 91m.

Long-range night vision capabilities

This varifocal security camera provides you peace of mind, boasting 140 feet of excellent night vision ability. It uses an automatic Infrared Cut Filter (ICR) designed to provide you with sharp and accurate color video during the day, and detailed black and white infrared video at night.

Enhanced Clarity in Low-Light Situations

Your camera uses DNR (Digital Noise Reduction) technology to filter out noise from low-light settings as well any noise caused by motion. By eliminating graininess, your camera provides a cleaner, more accurate image with better clarity, sharpness, and improved motion detection, enhancing your HD experience even in the dark! Not only does DNR reduce noise, but it reduces video file sizes as well, giving you greater disc space for storage.

Engineered for the outdoors

The LNB3373SB security camera can withstand virtually any kind of weather. It even continues to operate in temperatures as low as -30 degree C (22 degree F).
