|
| == 📘 Introduction ==
| |
| Geofencing is a core feature in modern GPS tracking systems. It allows users to define virtual boundaries on a map. When a GPS-tracked vehicle or asset enters or exits these areas, the system automatically triggers alerts or actions.
| |
|
| |

| |
|
| |
| == ⚙️ How Geofence Works ==
| |
| * A geofence can be a circular or polygonal area defined by latitude and longitude.
| |
| * The Discovery 4G GPS tracker continuously checks its current location via satellite.
| |
| * The system compares this live data against the predefined geofence area.
| |
| * If the asset enters or exits, the event is logged or notified based on configuration.

| == 🌐 How to Get Coordinates from Google Maps ==
| |
| # Open [https://maps.google.com Google Maps]
| |
| # Search for your desired location (e.g., warehouse, school).
| |
| # Right-click on the location and select '''“What’s here?”'''
| |
| # Note the coordinates shown (e.g., '''10.0556255, 76.3544891''')
| |
| # Use this as:
| |
| ## Center point for circular geofences
| |
| ## Corner points for polygon geofences (at least 3, ideally 4–6)
| |
| # Enter the values into the command format explained below.
| |
|
| |
| '''Note''': A maximum of '''6 geofences''' (circle or polygon combined) can be configured on any Transight telematics device.

|
| |
| == ✅ Geofence Command Format ==
| |
| * '''Status''': 1 = Enable, 0 = Disable
| |
| * '''Geofence ID''': Unique ID (e.g., 1313, 1777)
| |
| * '''Alert Type''': 1 = Entry, 2 = Exit, 3 = Both
| |
| * '''Shape''': 0 = Circle, 1 = Polygon
| |
| * '''Latitude/Longitude''': Decimal format (e.g., 10.0556255, 76.3544891)
| |
| * '''Radius''': Only for circles (in meters)
| |
| * '''#''': Used to separate parameters
| |
| * '''&''': Must be added at the end of polygon commands

| |
|
| |
| * Status: 1
| |
| * Geofence ID: 1777
| |
| * Alert Type: 3

|
| |
| == 💾 Save Configuration ==
| |
| After setting up geofences, you must execute the below command to save the configuration permanently:
| |
|
| |
| <pre>
| |
| SET TSMR:2
| |
| </pre>
| |
|
| |
| ----
| |
|
| |
| == 🔍 To Check Configured Geofences ==
| |
| Use the command:
| |
| <pre>
| |
| GET CUGF
| |
| </pre>
| |
|
| |
| This will show all geofences currently saved in the device memory.
| |
|
| |
| ----
| |
|
| |
| == ✅ Final Verification ==
| |
| After setup:
| |
| * Ensure the device has a GPS fix.
| |
| * Drive or move the asset in and out of the geofenced area.
| |
| * Confirm alerts are received/logged as expected.
