GENERAL DESCRIPTION
The ADSW4000 ADI EagleEye™ PeopleCount algorithm enables a
people counting function within internal spaces, such as
meeting rooms or office spaces. The system edge node analytics
unlocks informed insights and analytics with an accurate and
secure people counting capability. This data can provide the
insight to improve asset and people management, social
distancing, security, employee engagement, space utilization,
labor productivity, and energy efficiency.
The ADSW4000 is designed to operate solely with the Analog
Devices, Inc., ADSP-BF707 Blackfin+® core embedded processor
(ADSPBF707BBCZ4-EGE) and is optimized for a CMOS 2D
video graphics array (VGA) sensor and lens (the recommended
Chicony CYFI013 module incorporates an ON Semiconductor®
ASX340AT3C00XPED0-DPBR CMOS image sensor, Chicony
YT70005 lens, and lens holder with infrared (IR) filter).
The ADSW4000 ADI EagleEye™ PeopleCount algorithm provides
up to a 90% accurate people count within the target area.
The following are the accuracies achieved for tested radii from
3 m to 5 m:
• 90% accuracy in 3 m radius
• 85% accuracy in 4 m radius
• 80% accuracy in 5 m radius
