Overview

The Monoprice 138514 4K Bullet HD-TVI Security Camera is built for users who need high-resolution surveillance without replacing their entire recording infrastructure. Capturing video at 8.3 megapixels, it delivers 4K detail that makes it easier to identify faces, license plates, and other critical details in playback. The 4-in-1 design supports TVI, CVI, AHD, and CVBS output formats, so it can connect to virtually any modern DVR system. The motorized varifocal lens covers a 2.7mm to 13.5mm range with remote pan, tilt, and rotation controls, providing flexible framing from wide-angle coverage to tighter telephoto views without requiring a technician on site.

For low-light and nighttime surveillance, the camera employs Monoprice's Matrix IR 2.0 technology, which distributes infrared illumination more evenly than traditional IR LEDs. This eliminates the overexposed hot spots and halo effects that plague many security cameras, resulting in clearer footage across the entire frame at distances up to 131 feet. Additional image processing features include digital noise reduction to clean up grainy low-light footage and backlight compensation for scenes with strong contrast. The IP67-rated housing protects the camera from dust, rain, and extreme temperatures, making it suitable for year-round outdoor deployment.

Key Features

The Matrix IR 2.0 feature provides superior illumination and imaging over more traditional IR illumination solutions. It can illuminate to distances up to 131 ft in 0 lux conditions with more uniform exposure, particularly at the edges of the image. Matrix IR eliminates overexposure and hot spots (halo or spotlight effects in an image), Reduces interference and video noise, with a more vivid image Overall. It is more energy efficient and has a longer lifespan with better heat dissipation than

Digital noise reduction (DNR): image noise can come from a variety of sources, but is most often associated with low light conditions, resulting in a "grainy" Image. This noise not only interferes with the ability to clearly distinguish individual image elements, but also increases the storage space required for any given image. The DNR circuitry uses a digital comb filter to eliminate video noise.
