APS is creating a safer and more welcoming learning environment. To ensure the safety of our students and staff, Evolv Express detectors will be used at our Alamogordo High School campus starting in the 2024/2025 school year.

The rising threat of gun violence in schools creates anxiety that keeps both students and staff from doing their best work. Establishing a safe and welcoming school atmosphere can improve students' performance while attracting and retaining exceptional staff. Traditional metal detector weapons screening amplifies security anxiety by creating friction and generating frequent false alarms, leading to inconvenient delays and the risk of embarrassing and possibly biased secondary searches. Evolv Express® presents a more effective and dignified solution, fostering a safer, more inclusive environment that bolsters academic achievement and staff retention.

Express Capabilities

Trusted by hundreds of schools nationwide, Evolv Express uses artificial intelligence to put the focus on weapons, not individual people or harmless items. By significantly reducing false alarms, it helps streamline the school arrival experience and alleviate stress for students and staff. The system’s unique image-aided alarms help reduce opportunities for bias by shortening and focusing on secondary searches. Express helps schools take action against gun violence while preserving the safe and welcoming learning environment that students and staff deserve.

Evolv Health & Safety

Evolv is dedicated to safety, quality, and consistency in the delivery of our products, as well as providing accommodations for use by people of all abilities. Products undergo testing and certification to meet various
usage requirements defined by national and international governments and agencies.

Evolv Express® systems improve security by reliably detecting concealed threats and help enable a directed search, leading to a more dignified and respectful screening process that helps empower security professionals and enhances the visitor experience. Express is proven to operate up to ten times faster than traditional metal detectors with its dual-lane, free-flow entrances and fusion of new sensor technology and artificial intelligence. The system is built to spot weapons while ignoring most harmless personal items while visitors walk through at a natural pace.

How It Works
The extremely low-frequency radio waves (ELF) used by the Evolv Express induce magnetization and/or currents in metal objects passing through, both of which can be characterized via magnetic polarizability tensors. Using
our physical models, the Express recovers the data from the magnetic polarizability tensors and extracts features from them, which in turn correlate with the physical properties of the object including volume, shape, conductivity, and permeability. Using large databases of threats, including firearms, metallic IEDs, and other threats as well as databases of typical benign objects, including keys, cellphones, belts, shoes, coins, tablets, and laptops, the classifier is trained to distinguish between the two classes via machine learning techniques.

Comparable Use of Extremely Low-Frequency Radio Waves
Evolv Express uses extremely low-frequency radio waves (ELF) in the range used by Electronic Anti-Theft Systems (EAS), widely deployed in retail settings for loss prevention. Implantable electronic medical devices may be affected by
electromagnetic radiation emitted from devices that operate in this range.1

Evolv Express System

Implanted Electronic Medical Devices
The US Food and Drug Administration (FDA) has determined the likelihood of EAS systems interfering with implanted medical devices is extremely low, and any effects on the implant and the wearer were
typically transient and unlikely to cause clinically significant symptoms in most wearers. The FDA recognized the likelihood of ELF systems interfering with implantable electronic medical devices is low, however, they believe implant wearers should be notified wherever and whenever extremely low-frequency radio wave systems (ELF) are in use. 2
Appropriate language for such labeling or signage may include: “Electronic Security System in Use.”


For Evolv Express, the same approach
and considerations should be embraced by individuals with implanted electronic medical devices.

Evolv Technology protects everyone’s fundamental right to be safer in all the places people gather. With Evolv, a positive visitor experience is balanced with a proactive approach to enable security anywhere, without
disruption to traffic flow—including at schools, sports stadiums, entertainment venues, hotels and conference centers, airports, special events, houses of worship and
government agencies.
