A geofence is one of the most powerful features of any GPS tracker — it creates an invisible virtual boundary on the map. When your vehicle crosses that boundary (enters or exits), you get an instant alert on your phone. For Patna parents tracking teen drivers, fleet managers monitoring vehicles across Bihar, or business owners protecting parked vehicles overnight — geofence alerts are invaluable.

This step-by-step guide walks you through setting up geofence alerts on the Protrack app (which Alike GPS uses), with clear instructions for both Android and iOS.

What Is a Geofence and Why Do You Need One?

A geofence is a virtual geographic boundary you define on the map. You can create:

• Circular geofence: Draw a circle around your home, school, office, or factory. Get alerted when your vehicle enters or leaves.
• Polygon geofence: Draw a custom shape — useful for marking an entire colony, city area, or construction site in Bihar.

Common Geofence Uses in Patna & Bihar

• 📍 Home boundary: Get alerted if your bike or car leaves the home area at night (theft detection)
• 🏫 School zone: Parents get notified when the school bus enters the school and when it leaves
• 🏗️ Construction site boundary: Alert when equipment leaves the project site after hours
• 🏙️ City limits: Get alerted if a company vehicle crosses into an unauthorized area outside Patna
• ⛽ Fuel station exclusion zone: Alert if a driver visits an unauthorized fuel pump

Step-by-Step: Setting Up a Geofence in Protrack App

Step 1: Open the Protrack App & Log In

Open the Protrack app on your Android or iPhone. Enter your registered phone number/email and password. You'll see the map view with your vehicle(s) shown as icons.

Step 2: Select Your Vehicle

Tap on your vehicle's icon on the map, or select it from the vehicle list (bottom sheet). This opens the vehicle detail panel showing current speed, location, and status.

Step 3: Access Geofence Settings

In the Protrack app:

1. Tap the hamburger menu (≡) in the top-left corner.
2. Select "Geofence" or "Fence" from the menu (label may vary slightly by app version).
3. You'll see a list of existing geofences (empty if this is your first one).
4. Tap "+ Add Geofence" or the plus icon (+).

Step 4: Draw Your Geofence on the Map

The map view opens for zone drawing. You have two options:

Option A: Circular Geofence (Recommended for beginners)

1. Select "Circle" shape option.
2. Tap on the map to set the center point (e.g., your home in Kankarbagh, Patna).
3. Drag the radius slider to set the zone size. For a home compound: 50–100 metres. For a neighbourhood: 500 metres. For a city zone: 2–5 km.

Option B: Polygon Geofence (For custom areas)

1. Select "Polygon" shape option.
2. Tap multiple points on the map to trace the custom boundary (e.g., outline of a construction site or colony boundary).
3. Connect the last point to the first to close the polygon.

Step 5: Configure Alert Settings

After drawing the zone, configure the alert behavior:

• Alert on: Entry — Get notified when vehicle enters the zone
• Alert on: Exit — Get notified when vehicle leaves the zone
• Alert on: Both — Get notified on both entry and exit (recommended for theft protection)
• Notification method: App push notification (always), SMS (optional), Email (optional)

Step 6: Name the Geofence & Save

1. In the Name field, type a descriptive name like "Home - Boring Road" or "Office - Dak Bungalow Road".
2. Optionally set a Schedule — some apps let you activate geofence only during specific hours (e.g., night-time only for theft protection).
3. Tap "Save" or "Create".

🎉 Your geofence is now active! The next time your vehicle enters or exits the defined zone, you'll receive an instant alert.

Step 7: Test Your Geofence

Test it immediately:

1. Ask someone to move your vehicle (or drive it yourself) out of the geofence zone.
2. Your phone should receive an "Exit Alert" within 30–60 seconds.
3. Drive back into the zone — you should get an "Entry Alert".

If alerts aren't working, check: (a) App notifications are enabled in phone settings, (b) Protrack app has background location permissions, (c) Vehicle tracker has cellular connectivity (check signal status in app).

Advanced Geofence Uses for Bihar Businesses

School Bus Route Monitoring in Patna

Set a geofence around the school (e.g., DPS Patna on Boring Road). Parents automatically receive an app notification when the bus arrives at school and when it departs — eliminating the need for manual phone calls to the bus driver.

Fleet Trucks — City Limits Enforcement

Set a geofence around Patna city limits. Get alerted if a delivery truck operating within city runs exits into NH-19 or NH-30 without authorization — preventing unauthorized out-of-city trips.

Construction Site Night Security in Bihar

Set exit geofences on all equipment at construction sites and activate them from 6 PM to 6 AM only. Any equipment moving at night immediately triggers an alert — giving you time to call the site security or police.

FAQs — Geofence GPS Tracker

How many geofences can I create per vehicle?

The Protrack app allows unlimited geofences per vehicle. You can create separate zones for home, office, school, colony, state border — as many as you need.

Does the geofence work when my phone is off?

Yes. Geofence processing happens on the server, not your phone. Even if your phone is off, the server logs the entry/exit event. When you turn your phone back on, you'll see the alert in your notification history.

Will I get a geofence alert if the GPS tracker loses signal temporarily?

If the tracker briefly loses signal and then regains it outside the geofence, you'll receive the exit alert as soon as connectivity is restored. The timestamp will reflect the actual time of exit.

Can I set different geofences for different vehicles in my fleet?

Yes. Each vehicle has its own independent set of geofences in the Protrack platform. A school bus has its school zone; a delivery truck has its city zone; a personal car has its home zone — all managed separately.

Conclusion

Setting up a geofence alert takes under 5 minutes and provides one of the most powerful vehicle security features available. For Patna parents, fleet managers, and business owners in Bihar — a geofence is your 24/7 silent security guard that never sleeps. Set it once, and it works automatically forever.
