Enjoy high quality 4K video day or night, and the flexibility of selecting your outputs and field of view with the Alibi 8.0 megapixel HD-TVI 200' IR varifocal turret dome security camera.

This varifocal turret dome camera features an 8.0 MP (4K) high-performance CMOS and an active imaging pixel array of 3840 (H) x 2160 (V) that produces superior HD-quality video.

4 in 1 video output allows this camera to be compatible with almost any HD analog camera system (TVI/AHD/CVI/CVBS), for extreme flexibility during system upgrades. Keep your existing cables and upgrade your cameras with minimal effort.

The camera’s motorized varifocal lens covers a wide area with a horizontal FOV of 108.1° to 45.6°.

For nighttime surveillance or any low-light application, this varifocal HD camera features cutting-edge Full Frame Illumination technology, which:

  • Reduces overexposure of the IR LEDs at the center of the image
  • Increases illuminant efficiency up to 30%
  • Produces LED light in rectangle form to better fit screen size
  • Captures images up to 200′ in the dark without washing out the subject at closer ranges

Up the Coax (UTC) technology enables you to control the camera’s onscreen display (OSD) from the camera, the Alibi Witness app, the Alibi Central Management System, the DVR (UTC), or a web browser.

This varifocal turret dome security camera also has a True Day/Night feature that allows it to capture better images in any lighting conditions.

And with an IP67 weather-rated metal enclosure, this varifocal turret camera has an operating rating of -40° to 140°F and is protected from elements such as dust and sand, making it an ideal outdoor security solution.

Key Features and Capabilities:

Megapixel Resolution – Cover more area and see more detail. Megapixel cameras can cover a larger area without compromising image quality, providing the level of detail needed for facial recognition and license plate identification.

  • Produces clearer, brighter images in low light and at night
  • Delivers a wider illumination spread
  • Unique rectangular IR LED design produces a uniformly illuminated image across the entire screen
  • Reduces overexposure at the center of the image and eliminates hot spots
  • Eliminates blooming from lights by reducing ambient light pollution
  • Reduces video noise for a clearer nighttime image, and reduces bandwidth consumption and video storage requirements
  • Delivers 30% greater energy efficiency
