Unlike traditional cameras that use a 1/1.8 inch front-illuminated Complementary Metal Oxide Semiconductor (CMOS) sensor, Huawei X22 Series Face Capture Soft-Light Bullet Cameras use a 1/1.8 inch back-illuminated CMOS, greatly increasing the amount of light that reaches the image plane and improving overall image quality.
Featuring 12-55 mm lenses, the X22 Series is comprised of four cameras, with either a 2 megapixel or 6 megapixel image sensor, offering a maximum resolution of up 3072 x 2048 pixels (the X2261-FL). The cameras all provide notable low-light performance, with minimum illumination requirements as low as 0.0001 lux (black and white on the X2221-FL and X2221-FLG) and a wide Dynamic Range (WDR).
Alongside excellent image quality, the cameras offer built in Neural Processing Units (NPUs), which improve the computing efficiency of deep-learning algorithms such as face detection and attributes recognition.
Indeed, Huawei X22 series cameras capture a maximum of 100 faces per frame — three to five times that of the industry average — even in densely populated areas, without any missed snapshots. Powered by Artificial Intelligence (AI), the cameras recognize various scenarios — such as backlight, rain, fog, and scenarios where objects move quickly — adjusting snapshot parameters accordingly. In addition, X22 cameras track, filter, and evaluate faces in real-time to generate optimal face snapshots and increase the accuracy of secondary recognition.
Power over Ethernet (PoE) power supply simplifies camera deployment and maintenance. With built-in soft-light illuminators, the cameras do not need an external illuminator, further simplifying the installation process.
