AlertGPS Active Halo® 4G LTE Capabilities

Our safety wearable is easy to use and has only one button on its face to press to initiate a two-way SOS voice call to our 24/7 monitoring center. The hands-free speakerphone requires no action on the part of the device holder to answer. The employee’s location information is instantly available to our monitoring center, and also visible on the company’s secure dashboard.

The simplicity of the device design recognizes that in stress situations, fine and complex motor skills (such as those required to operate a cell phone) are diminished, along with the ability to multi-task.

Size: slightly larger than a key fob
Attachment options: lanyard and belt clip
Charging cord: chargeable via wall plug and car USB port

The AlertGPS Platform

  • AlertGPS’s Scalable, Redundant Cloud-Based Architecture provides optimum availability while ensuring customer privacy and segregation.
  • Multi-Tenant architecture provides each customer their own secure, fully customizable dashboard that’s easy to use and can be accessed via computer, smartphone or tablet.
  • Authorized users can actively monitor current & past locations of all workers, graphically displayed on an interactive map. A log of each location is instantly viewable for each worker.
  • Robust role-based permission architecture allows customers to (i) create employee groups, (ii) assign specific alerts to managers or carriers within each group, and (iii) view-limit managers to only those employees for whom they are responsible.
  • Full Reporting & Analytics capabilities (downloadable in PDF, CSV & Excel)
  • The AlertGPS IoT Platform offers customizable Alerting options. Each Alert can be sent in real-time via email/text to an unlimited number of designated recipients (e.g. managers, safety officer, etc.).

AlertGPS Platform Alerting Features

SOS Alerts: Upon SOS button press, the AlertGPS system generates an SOS Alert to all designated Alert recipients (e.g. employee’s manager).
SMART ZONE ALERTS Create Smart Zones around specified geographic areas and designated Alert recipients will receive a Zone Alert immediately after the device-holder enters or exits the Smart Zone.
PREDATOR ALERTS Predator Alerts are delivered to designated Alert recipients when the device-holder comes within a pre-selected range of a registered sex offender’s home (e.g. 500 feet).
THREAT ZONE ALERTS Threat Zones are established by the customer around known hazardous areas (e.g. a home with an aggressive dog) and are a useful way of ensuring compliance with OSHA’s requirement that employers provide employees advance notice of a known threat. Threat Zone Alerts are delivered to designated Alert recipients when the device-holder comes within a preselected range (e.g. 1000 ft) of a Threat Zone.
CHECK-IN ALERTS When a worker presses the Check-In button on their device, a Check-In Alert with the worker’s location is delivered to designated Alert recipients.
SPEED ALERTS When the device-carrier exceeds a selected maximum speed threshold (e.g. 70mph) a Speed Alert is delivered to designated Alert recipients.
BREADCRUMB ALERTS Breadcrumb Alerts enable managers to be alerted regarding the employee’s location on a pre-determined schedule. So, for example, if a manager needs to keep closer track of a new employee and the manager wants to have the employee’s location information pushed to them every hour via text, the manager just sets a Breadcrumb Alert and select the desired reporting interval to automatically receive regular SMS alerts with the employees exact location.
FALL DETECTION ALERTS The AlertGPS system generates a fall related SOS Alert when the device detects a fall.

The Monitoring Center

The AlertGPS Monitoring Center is fully redundant, and available 24/7/365. All Monitoring Center agents are trained to handle any type of emergency situation and have the ability to dispatch emergency assistance anywhere nationwide pursuant to an action plan customized to meet the customer’s specific requirements.

If desired, customers can elect to self-monitor their workers and to manage and respond directly to any incidents.

Monitoring Center Features

TRAINED PROFESSIONAL AGENTS: Trained professionals available 24/7 to answer the call, assess the situation and provide the most efficient emergency service available.
RAPID CALL RESPONSE: Average call answer time is less than 8 seconds. Handles over 12 million signals per month.
CUSTOMIZED ACTION PLANS: Our agents follow an action plan designed by you with your specific company needs in mind.
HIGHEST INDUSTRY CERTIFICATIONS: UL Listed. Installation Quality (IQ). CSAA 5 Diamond Certified.
AFTER-INCIDENT UPDATE: With our superior alerting system, we provide an after-incident update to the customer’s designated representative(s) in real time.
TOTAL SYSTEM REDUNDANCY: Two Fully Redundant locations with immediate failover capabilities.


AlertGPS develops a Customized Action Plan for each customer, specifying how all emergency signals will be handled. Customers have the options to:

  • Establish a Priority Call List of customer representatives to receive phone calls in the event of an emergency dispatch situation (e.g. the customer’s Safety Officer)

  • Establish customized safety protocols

  • Select a default emergency dispatch option

  • Designate customer representative(s) to receive post-event disposition emails detailing the emergency signal outcome



If a worker feels uneasy for any reason (e.g. unfamiliar neighborhood, dark parking lot), they can press the SOS button and speak with a Monitoring Center agent who will stay on the line until the worker indicates that all is well. The agent is prepared to dispatch help immediately if needed.


If a worker falls, the Active Halo® device will automatically initiate an audible message. If the device-holder does not cancel the alert the device auto-calls our Monitoring Center. The agent will dispatch emergency assistance if help is needed, even if the worker is non-responsive.


The Monitoring Center can call into an Active Halo® device to initiate a 2-way voice conversation with the worker. No action is required by the lone worker to answer the device – the call is automatically connected, and the hands-free speaker is engaged.

Active Halo® 4G Location Reporting Options

Utilizing GPS, Assisted GPS, WiFi and Bluetooth technologies, AlertGPS has location reporting options to fit any enterprise use case. The Active Halo® device transmits data via the 4G LTE cellular network, and supports Wi-Fi and SMS failover for the transmission of data in areas where cellular data signals are insufficient.

New Privacy Options Include:

Device location information is reported continuously on any selected reporting interval (e.g. every 5 minutes).

Device location information is provided only during a pre-selected reporting period (e.g. Mon-Fri, 9am-5pm EST).

Location information is reported only if SOS or Check-In button is pressed, or a fall is detected.



Car Accident

A mobile worker gets in an accident, slides on an icy road, or becomes lost or stranded.  They can press the SOS button and speak with an agent who will dispatch emergency assistance.


Companion Mode

If a worker feels uneasy for any reason (visiting an unfamiliar neighborhood, walking through a dark parking lot), they can press the SOS button and speak directly with an agent. The agent will stay on the line until the worker confirms all is well or, if needed, our agent will dispatch help.



If your worker wants you to know when they have arrived or left a location, or is alone and just wants you to know where they are, they can send their location by pressing the Check-In button-. A Check-In Alert with name and location information will immediately be sent to all designated Alert recipients via email and/or text.


Mass Notification

If you need to reach your personnel during an emergency event (e.g. extreme weather, active shooter, disgruntled employee), you can use the AlertGPS mass notification system to send mass text alerts to your personnel in the field.


Need Help!

If a worker ever feels unsafe or is threatened or injured, they can simply press the SOS button for immediate assistance.  The SOS alert triggers a 2-way call to our 24/7 monitoring center. Our agents are trained to assess the situation and will dispatch emergency help nationwide 24/7.
