DS-2DF8C442IXG1-ELW 8C series 4MP 42X 'DarkFighter' IR network speed dome camera. Features: 1/1.8-inch progressive scan CMOS; high-quality 4MP video recording sensor; excellent performance in low light using 'DarkFighter 2.0' technology; clear images in bright light with 150 dB AWDR technology; 42x optical and 16x digital zoom allows for close-up shots in wide spaces; wide night vision range – up to 400 m IR range; water and dust resistance (IP67) and vandalism resistance (IK10) – excluding the lens glass; face capture support – motion detection, capture, ranking, and selection; multi-traffic support – vehicle detection; smart horizontal and vertical position correction. IP67 rating means the device is fully protected from dust and resistant to water jets under normal use conditions. Due to water and dust resistance (IP67), cameras can reliably operate even in harsh outdoor conditions, ensuring continuous protection and monitoring, regardless of weather or environment. This is an extremely important surveillance system feature where reliability and operational continuity are key. WDR 130 dB technology allows surveillance cameras to maintain a clear image even under strong background lighting. Due to the wide dynamic range, the camera can evenly distribute light across the entire image, which helps preserve detailed object details even under the most complex lighting conditions. Human and vehicle detection is an advanced feature used in video surveillance systems, allowing automatic recognition and tracking of people and vehicles in the monitored area. This system's operation is based on the analysis of the image generated by the camera's sensor, which enables the identification of characteristic features of people and vehicles. The human and vehicle detection function can be used for various purposes, such as monitoring traffic in parking lots, tracking people in buildings, or identifying vehicles on roads. Hikvision independently developed a smart algorithm that can significantly reduce video bitrate, based on the standard H.265 codec. Using H.265+, video quality is nearly equivalent to H.265/HEVC, but the required transmission bandwidth and storage capacity are reduced due to three core technologies – predictive encoding, noise suppression, and flexible bitrate control. 3D DNR (3D Digital Noise Reduction) function is an advanced technology designed to reduce digital noise in the image in three dimensions: spatial, temporal, and pixel level. Thanks to it, surveillance cameras can generate clearer and sharper images, removing unwanted artifacts and improving recording quality even under complex lighting conditions. The integrated SD card slot function allows direct recording of video material to an SD memory card located in the surveillance camera. Due to this solution, cameras can record locally and store recordings on an SD card without using external data storage devices. Hikvision's IR infrared function is an advanced solution used in surveillance cameras, allowing image recording even under low light or complete darkness. Thanks to infrared LEDs emitting infrared light invisible to the human eye, cameras can obtain clear video recordings at night. This technology ensures reliable monitoring of low-light areas, which is particularly useful in outdoor surveillance systems, providing high video quality even under the most challenging lighting conditions.
