1. Overview of PAInet and Gunsens

PAInet (pronounced "pie-net") is a Physical AI platform for public safety. PAInet connects and manages Gunsens PAI gun-threat detectors, Gunsens SOS buttons, and the Gunsens App through enterprise SaaS—providing early warning of shooting threats and coordinated response to any emergency in schools, workplaces, and public spaces.

Key Concepts:

• Location – A place you’re protecting.
• Floor Plan – A map showing the exact position of alerts and responding Police Officers.
• Alert – A warning triggered by either a Gunsens PAI or a Gunsens SOS device.
• Scene – Like a police "crime scene", this refers to an Alert event associated with a particular Location.

2. Alerts

Gun threat and SOS alerts are instantly relayed to the public via the Gunsens App and to first responders through direct integration with 911. This ensures rapid response and seamless coordination.

​ Gun threat alerts:

Automatically triggered by a Gunsens PAI threat detector (also called a PAI, pronounced "pie", like apple pie). PAIs can be purchased and managed in Settings on the Home tab bar.

​ SOS alerts:

Manually triggered by three-clicks on the Gunsens SOS button. The SOS button must be within 50 feet of the associated smartphone to successfully trigger the alert. It can activate an alert even if the smartphone is locked.

Gunsens SOS buttons can be purchased and managed in Settings on the Home tab bar.

3. App Navigation
The Gunsens App features two tiers of tab bars for handling alerts. The primary Home tab bar provides an overview of active and inactive alerts. When a specific alert is selected, the secondary Alert tab bar appears, offering detailed options and actions related to that alert.

Using The Home tab bar:

• Map – View a map of all active alerts. Tap an alert icon to see its details.
• Alerts – Browse alerts in chronological order. Tap an alert to access the Scene, Comments, Videos, and Directions.
• SOS – Manage your Gunsens SOS button and check its status.
• Guide – Get help and learn how to use the Gunsens App.
• Settings – Manage your account, devices, notifications, and Gunsens App preferences.

Upon opening the Gunsens App, users are directed to the Map screen, which displays active threat alerts and provides access to the Home tab bar for managing these alerts.

Yellow indicators represent gun threat alerts, while red indicators represent SOS alerts. To view details, tap on a threat notification or one of the alert indicators on the map.

Fig. 3-2 Active alerts.

The Alerts screen shows all alerts in chronological order. Active alerts are marked with yellow and red indicators, while inactive alerts are shown in black and white. Alerts automatically deactivate after 24 hours.

To filter which threat alerts you see, tap the Settings item on the tab bar and select the Manage Alerts item. For example, you can filter to see only alerts within a 5-mile radius of your current location when the switch is ON.

Fig. 3-4 Setting alert filters.

Below is an explanation of all Manage Alerts options:

Alert Radius

• Only alerts within the specified radius in miles are reported.

Enable Loud Alerts

• OFF (default) — “Amber Alert” sound is muted.
• ON — a loud “Amber Alert” sound is heard when alerts arrive.

Using the Alert tab bar:

• Scenes – Swipe horizontally through all Scenes.
• Comments – Read or add coments for a location.
• Bodycam – Use your phone’s camera to live stream from the Location.
• Videos – Watch all videos for a Location.
• Directions – Get directions to the alert's Location.

When an alert is selected, either from the Alerts screen or the Map, the app opens the Alert tab bar which provides tools for managing Scenes (as in "crime scenes") related to a specific Location.

If an alert was triggered by a Gunsens PAI or a Gunsens SOS button that is in the vicinity of a Gunsens PAI, the Scenes item on the Alert tab bar displays a floor plan and the address of the Scene, including the floor number and the appartment or classroom number. Otherwise, the screen shows the member's photo instead of a floor plan.

4. Managing Gunsens SOS

To install a Gunsens SOS Button:

1. ⚠️ Important: When you take the Gunsens SOS button out of the shipping box for the first time, you’ll need to turn it on. Press and hold the button for a couple of seconds until it beeps. This step only needs to be done once—the Gunsens SOS button will stay on permanently and won’t need to be turned on again.
2. Open the Settings menu in the Gunsens App and tap “Install a Gunsens SOS Button.”
3. Use your smartphone’s camera to scan the QR code located on the back of the Gunsens SOS button.

The status of your installed Gunsens SOS button is visible on the SOS tab in the Home tab bar.

5. Managing Gunsens PAI

You can add a Gunsens PAI detector (PAI) to your account in four simple steps: (1) add a location, (2) upload a floor plan, (3) scan the PAI's QR code, and (4) position the PAI on the floor plan.

Your account can include multiple Locations and each location can have several floor plans. You can add any number of PAIs to each floor plan.

Step 1 – Adding a location:

Tap the Manage Sensors item on the Settings screen to open the Locations screen, where you can add any number of locations.

Fig. 5-1 Adding locations.

Step 2 – Adding a floor-plan:

Tap a location on the Locations screen to open the Floor Plans screen, where you can add plans for each floor of the building.

Fig. 5-2 Adding floor-plans.

Step 3 – Adding a Gunsens PAI detector:

6. Inviting Members to Your Gunsens Account

The Gunsens App is designed to effectively manage and respond to threat alerts by using a structured membership system. Different users play different roles in ensuring safety, from receiving notifications to managing alerts, Gun Sensors and SOS Buttons.

To handle these varying responsibilities, Gunsens accounts are divided into five membership tiers: Owners, Admins, Police Officers, Viewers, and Kids. This hierarchy ensures that every user has appropriate access and control, enhancing the app’s functionality in complex environments like schools, businesses, and public spaces.

For instance, a school can purchase Gunsens SOS buttons for all of its students. The school then invites students to join its Gunsens account as Kids. Once Kids install their Gunsens SOS buttons, the school, as the Owner of the accunt, is automatically billed for their monthly monitoring subscriptions.

Owners:

• Add or remove Admins, Viewers, and Kids.
• If verified as law enforcement, can add Police Officers to their account.
• Manage all connected Gunsens PAI detectors.
• Pay for Gunsens PAI detectors and Gunsens SOS button subscriptions for all invited users.
• Install their own Gunsens SOS buttons.

Admins:

• Add and remove Viewers, and Kids.
• If verified as law enforcement, can add Police Officers.
• Manage Gunsens PAI detectors.
• Install their own Gunsens SOS buttons (with subscription charged to the Owner).

Police Officers:

• Install their own Gunsens SOS buttons (subscription is billed to the Owner).
• Are identified by a blue shield icon next to their name.
• Are able to tap a red, blue or green "Presence" icon on a Floor Plan to see names of people present on the scene.

Viewers (17+):

• Install their own Gunsens SOS buttons (with subscription charged to the Owner).

Kids (Under 17):

• Install their own Gunsens SOS Buttons (with subscription charged to the Owner).
• Can only view their own Bodycam Videos—they cannot see other users’ Videos to protect them from potential exposure to violent content.

7. Mounting Gunsens PAI Detectors

Indoors:

• Indoors, detectors are installed similarly to smoke detectors, consisting of a detector unit and mounting bracket.

• First, attach the mounting bracket to the ceiling’s electrical box. Then, connect 110v power from the electrical box to the detector unit. Finally, twist the sensor unit onto the mounting bracket.
  
  

Outdoors:

• Gunsens  PAI detectors are waterproof and can be mounted outdoors like security cameras, on walls or lamp posts.
• First, attach the mounting bracket to a standard camera mount. Connect 110v power from the electrical box inside the camera mount to the detector, and twist the detector onto the mounting bracket.
