M-EFL Series Economical Face Capture Bullet Cameras

Unlike traditional cameras that use a front-illuminated Complementary Metal Oxide Semiconductor (CMOS) sensor, Huawei M-EFL Series Economical Face Capture Cameras use a back-illuminated CMOS, greatly increasing the amount of light reaching the image plane and improving overall image quality.

Available in a range of variable and fixed focal lengths, and sensor sizes — up to 4 megapixels and 12-55 mm, with the M2241-EFL — all M-EFL series camera offer extremely low-light face capture capability, with minimum illumination as low as 0.001 lux for some models.

Capturing up to 30 to 50 faces per frame, built-in Neural Network Processing Units (NPUs) improve the computing efficiency of deep learning algorithms such as face detection and attribute recognition. Indeed, instead of using algorithms to detect faces and bodies separately, the cameras support the associative snapshot of faces and bodies, providing multi-dimensional personnel information for the platform to aggregate.

The M-EFL series is designed for Safe Cities, campus surveillance, and other similar scenarios.
