The Annke I91DQ is a powerful 4K Ultra HD dome surveillance camera that combines advanced security features with exceptional image quality. Equipped with a 1/2.4" progressive scan CMOS sensor and a motorized varifocal lens with 4x optical zoom, the I91DQ delivers precise and detailed images, even in challenging lighting conditions. This camera is the optimal solution for demanding surveillance tasks where both wide-angle shots and close-ups of very high quality are required. The Annke I91DQ has a resolution of 3840 x 2160 pixels and records videos in high 4K Ultra HD quality. The advanced 1/2.4" progressive scan CMOS sensor ensures sharp images with a high level of detail, regardless of the time of day. The motorized varifocal lens with a focal length of 2.8 to 12 mm and 4x optical zoom allows for seamless switching between close-up and wide-angle shots without loss of quality. This feature is particularly useful for monitoring large areas or capturing specific details such as license plates. The I91DQ surveillance camera features intelligent dual-light technology that automatically adjusts the lighting mode to the current recording situation. In 24/7 color mode, the camera provides color images around the clock. In IR mode, the camera uses infrared light to deliver clear black-and-white images even in complete darkness. The intelligent dual-light mode combines these two functions: the camera remains in IR mode until motion is detected, then switches to color images to capture important details. The night vision range extends up to 30 meters, allowing for continuous monitoring even at night. With its active deterrent features, the Annke I91DQ surveillance camera offers an advanced security solution.
