The Annke I91DQ is a powerful 4K Ultra HD Dome Surveillance Camera that combines advanced security features and exceptional image quality. Equipped with a 1/2.4 progressive scan CMOS sensor and a motorized Vario lens with 4-fold optical Zoom, the I91DQ delivers precise and detailed images, even under difficult light conditions. This camera is the optimum solution for demanding surveillance applications, in which both wide-angle and close-up pictures in very high quality are needed.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-inch progressive scan CMOS sensor provides crisp images with Hohem detail regardless of the time of day. The motorized Vario lens with 2.8 to 12 mm focal length and 4-fold optical Zoom makes it possible to switch between near and wide angle recordings without any loss of quality. This feature is particularly useful for monitoring large areas or capturing specific details such as autographs.The I91DQ surveillance camera has an intelligent Dual light technology that automatically adjusts the lighting mode to the current recording situation. In the 24/7-color mode the camera delivers color pictures round 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 the IR mode until a motion is detected, and then switches to color images to capture important details. The night-vision range is up to 30 meters, enabling seamless monitoring even at night.With its active defense functions the Annke I91DQ surveillance camera offers an advanced security solution. By using a deep learning algorithm, the camera can differentiate between different objects such as people and vehicles and trigger an alarm accordingly. The built-in flash and spotlight alarms are activated to deter unwanted visitors before they can act. These functions make the Annke I91DQ a preventive solution in the field of safety technology.The I91DQ's H.265+ video compression technology is modern and allows the recording of high-quality videos with reduced memory requirement. This technology not only saves storage space but also bandwidth, reducing operating costs. With the support of microSD-cards with up to 512 GB the recordings can be stored without any problem even during long run times, without the need for additional hard disks.The Annke I91DQ can be operated via Power over Ethernet (PoE) as well as an external DC power supply. PoE simplifies the installation, since both the power supply and the data transfer is done via a single cable. This reduces the amount of wiring required and ensures a clean and simple installation.The Annke I91DQ dome surveillance camera features a built-in microphone that allows you to record audio in addition to video. Note, however, that the I91DQ does not support two-way audio. This means that you can only record sound, but real-time communication via speakers is not possible.With the protection class IP67 the Annke I91DQ is protected against water and dust and thus Ideal is suitable for the outdoor use. The camera is completely weatherproof and can withstand extreme weather conditions such as heavy rain, snow or dust storms. It remains fully functional even at temperatures from -30 °C to 60 °C and is thus a reliable choice for surveillance tasks in different environments. The IK08 certification provides additional protection against vandalism, so that the camera can be used reliably even in areas that are especially critical.This text is machine translated.
