Designed for use in outdoor surveillance applications, the SD522 4K PTZ IP Speed Dome Camera from Bolin Technology captures high-resolution video in extreme weather with ease. Outfitted with a 1/1.7' CMOS sensor and IR LED illuminator, the camera is capable of recording 4K images with H.264 and H.265 compression in low-light environments up to 250 feet away. An IP67-rated metal alloy casing protects against moisture and dust and the built-in heater-blower, rain wiper, and stain-free window ensure high performance in extreme weather conditions.

Zero Deviation Positioning provides precise movement at variable speeds with 22x optical and 16x digital zoom equipped with autofocus for clear close-ups. The breakout cable provides a BNC analog video output, 3.5mm audio I/O, and alarm input and output connections for the camera. The camera can be powered by PoE++ or a 24V source (AV or DC). Image parameters can be set for quick operation and firmware upgrades can be installed via the IP interface and RJ45 connection for constant improvement of the camera's preexisting features. Control of this ONVIF-compliant camera is achieved over IP through integration with video management software.
