ANNKE 4Pcs 4K 8MP PoE Varifocal IP Cameras with Two-Way Audio — 2.8mm-12mm 4X Optical Zoom, Smart Dual-Light Color Night Vision, Human & Vehicle Detection, Up to 512GB

High-resolution 4K imaging: Each ANNKE PoE IP camera delivers 3840*2160 resolution (4X clearer than 1080P) so distant details are sharper and easier to identify. The varifocal 2.8mm-12mm lens provides 4X Optical Zoom with auto-zoom capability to bring small features of people or vehicles into clear view on your smartphone. Two-way audio: Built-in mic and speaker let you listen and speak through the camera for real-time communication or deterrence. Smart human & vehicle alerts: The system can detect humans and vehicles with up to 99% accuracy. When an event is identified you can trigger audible and flashing warnings — choose from 12 default alarm sounds or record a custom voice alert. Alarm volume is adjustable up to 95dB and the flashlight alarm adds an extra visual deterrent. Flexible night vision modes: Three lighting modes adapt to different situations — default Smart Dual-Light, Full-Color Night Vision (lights always on), and IR Night Vision (lights off). In Smart Dual-Light mode the fill light activates only when human or vehicle movement is detected, while the camera remains in IR mode otherwise to avoid constant illumination. Easy PoE installation & weather resistance: The cameras use Plug & Play PoE so video and power travel over a single network cable for simpler setup. Built to IP67 standards, they withstand harsh weather for reliable outdoor or commercial use. Local recording options: Store footage on an NVR or insert a TF/Micro SD card up to 512GB(not included) into the camera for local playback. Package note: Only one 1m testing network cable is included in the box — additional network cables and an adapter must be purchased separately.
