System Operation
Operational Footprint
The following is the operational footprint for the CWD system and describes the approximate scan zone, decisions zone, and recommended resolution zone. The exclusion zone is an area that should be free of people and moving objects, such as swinging doors.
| Key Zone | Description |
|---|---|
| Scan Zone – 58 cm (23 in) | Optimal operation is achieved if visitors walk through this zone in a straight line at a constant speed. A decision is provided 0.5 seconds after the visitor exits the Scan Zone. This is the area surrounding the Receiver Towers. Keep this area free of moving objects, except those being scanned. |
See the current version of the Concealed Weapons Detection Installation Manual.

Requesting Assistance from the Security Operations Center
The Assist Request icon at the top of the analytics dashboard indicates that communication to the ACC system is available.
Sending an Alert to the ACC System
There are two ways to send an alert to the ACC system:
- An Assist Request—When the CWD system is deployed, an Assist Request button is enabled on the operator tablets. If an Assist Alarm has been created in ACC, then at any time, an operator can press the Assist Request button to notify the ACC system in the security operations center that immediate security assistance is needed.
- Tagged Threat Alert—When a potential threat is detected and displayed on the operator’s tablet, an operator can press to verify the threat. If an alarm has been created in ACC for this verified threat, then after the threat is verified, it is immediately forwarded as an alarm to the ACC system for further action. When a threat is tagged during the resolution process, the type of threat is sent to ACC.
Using the Assist Request Feature
- Press the Assist Request button at the top of the analytics dashboard. A dialog will appear confirming the assistance request.
- Press OK. An Assist Request acknowledgment will be displayed.
The Assist Request causes an alarm in the ACC system, and the views from the front and rear cameras start playing in the ACC Client that is monitoring the CWD, starting from the preset pre-alarm duration specified in the ACC alarm definition.
Using a Tagged Threat Alert
When an operator tags an alert from the CWD System as a threat, the notification is sent to ACC as an alarm indicating the type of threat tagged. These alerts are: Law Enforcement, Knife, Gun, and Threat (Other).
Threat Resolution No Potential Threat
Green indicates that there is no alarm.
Potential Threat
Red indicates that an alarm is in the lane. The image and the location of the potential threat will display on the tablet.
Cameras
- The CWD system has one Alarm Resolution camera per lane, located on the transmitter tower. Alarm Resolution cameras cannot be viewed from within ACC.
- In addition to the Alarm Resolution camera(s), there are two General Purpose cameras on the center/transmitter tower—one on the front and one on the rear.
Introduction
The Motorola Solutions Concealed Weapons Detection (CWD) solution powered by Evolv Technology is designed to address the active shooter epidemic by taking a proactive approach to keeping people and assets safe. Using advanced sensors and machine learning to detect a wide range of concealed weapons and threats, it is the world’s first and only touchless security screening solution that is conducive to supporting post-pandemic security screening requirements. The CWD system powered by Evolv Technology is a non-resource intensive solution that reduces labor costs by up to 70% and is proven to operate up to ten times faster, as it is more effective than traditional metal detectors with its touchless, dual-lane, free-flow experience.
Operating Data
- Power Supply: Voltage: 100-240V +/- 10%, Frequency: 50/60Hz, Power: 200W.
- Operating Temperature: Temp: -20C to 55C Ambient, Humidity – 95%RH Condensing.
- Altitude: Equipment rated for operating altitude up to 2000 m.
- Outdoor Use: IP56, Water resistant up to 5” from the ground
Partial protection against dust that may harm equipment. Protection against low-pressure jets (6.3 mm) of directed water from any angle (limited ingress permitted with no harmful effects).
Intended Use
The CWD system is designed as a high throughput automated threat detection system that provides automated detection of weapons such as firearms and IEDs. The CWD system conducts weapons detection screening at up to a rate of 3,600 persons per hour at a natural pace. Visitors/employees can carry all normal personal items with them through the screening process, including typical pocket clutter such as cell phones, keys, personal bags, backpacks, etc. The CWD system will be broadly deployed at high throughput venues for visitor screening and lower throughput venues for employee screening to minimize the threat of an active shooter or an incident of gun-related workplace violence.
Cleaning
Clean only with a dry cloth. When cleaning, unplug the power cord and wipe gently with a soft cloth to prevent scratching. Do not spray water or other liquids directly on the CWD system as electric shock may occur. Do not clean with chemicals such as alcohol, thinners, or benzine.
Using the Tablet
The tablet displays the analytics dashboard. The analytics dashboard provides the following:
- Status of the CWD Operation
- Configuration Settings
- Alarm Display
- Scanning Statistics

Alert Presentation
Alert Overview
The CWD system will present an alert when it detects a potential threat in Lane 1, Lane 2, or both lanes. The alert is presented on the CWD system tower with a red LED indicating the lane associated with the alert. The alert details are presented on the tablet.
Alert Location
Alerts appear on the tablet as a cube, to present the precise location in which to investigate the potential threat.
Alert Location Examples
The following examples show different alert scenarios and how to identify potential threat locations.
Single individual, no bag
Multiple camera angles assist in locating a potential threat in the left-hip area.
Single individual, with bag
Multiple camera angles assist in locating a potential threat in a backpack.
Multiple Individuals, no bag
Multiple camera angles assist in locating a potential threat on the left-hip area of the correct individual.
Lane Alerts
The tablet can be configured to display alerts in both lanes, in Lane 1 only, or in Lane 2 only.
Lane 1 Alert
Lane 1 – Tablet Description
Lane 2 Alert
Lane 2 – Tablet Description
Alert Queue
The alert queue will display past alerts. Each alert can be selected for larger display.
Alert Queue Mode
The alert queue determines how alerts are presented on the tablet. The alert display is presented in the following modes:
Alert Queue Description
Typical Alert Mode Configuration
When multiple tablets are used, a typical alert mode configuration might look like this.
Alert Tagging
Alert tagging allows operators to identify specific objects that cause an alert. This can be useful for screening analysis and for identifying common objects that cause alerts.
The categories of alerts are:
- Benign—Umbrella, Eyeglass Case, Headphones, Laptop, Nuisance (Other)
- Threats—Law Enforcement, Gun, Knife, Threat (Other)
The Queue thumbnails and Alert History pages indicate alerts that are tagged. As a best practice, tag all alerts. The categorization will become part of the statistics available in the analytics dashboard. Of the alerts generated, it will be possible to see how many were from specific categories, either threats or benign.
The image below shows the alert tagging drop-down list that is exposed when the red “+” symbol is pressed.
The image below shows the display when the alert tag is selected.
Simultaneous Alerts Examples
With Simultaneous Alerts enabled, two detected alerts occurring within a short-prescribed 0.5 second window will be shown on the tablet. This could be two alerts on one person, a single alert on two people in a single lane, or alerts on two people in an individual lane. Simultaneous alerts are indicated with a yellow border around two scan periods. The Queue thumbnails and Alert History pages also indicate a simultaneous pair with yellow border.
The image below shows two alerts—one on the left hip and another on the right ankle—on one person.
The image below shows a single alert on two people in separate lanes.
Alert Display Configuration Example
The image below shows two images from the same perspective, displayed side-by-side. These can be either one still image at left and one in-motion video loop at right, or two still images. Both configurations help guards gain a more complete, intuitive picture of where on the person or their bag a threat is located.
Alert History Grid Example
The image below shows simultaneous alerts outlined in yellow and tagged as benign objects (Eyeglass Case) and a threat object (Gun).
