How GPS Devices Detect Tampering
GPS trackers rely on multiple sensor technologies to quickly alert users when tampering occurs. These systems are essential for keeping assets secure in real time. These technologies have helped businesses protect equipment from theft and unauthorized use.
Light Sensors for Tamper Detection
Light sensors are a clever way to detect tampering. When the device is properly mounted, the sensor stays covered. But if someone removes the tracker, exposure to light triggers an alert. As Tracker Systems, Inc. explains: "The tamper sensor detects a change in light levels when the tracker is removed. The tracker then sends a change message to our server". This setup ensures users get instant notifications – via SMS, email, or a mobile app – when tampering occurs. Alongside light sensors, power monitoring serves as another effective detection method.
Power Loss Detection
For hardwired trackers, tampering is often detected by monitoring external voltage levels. If someone unplugs the device, like with OBD-II port trackers commonly used in vehicles made since 1996, a sudden voltage drop triggers an alert. In such cases, the tracker switches to its internal backup battery with long life (usually a lithium-polymer battery) to send a notification immediately. Different models handle power loss detection in unique ways. For instance, the Digital Matter Eagle identifies power removal instantly through hardware, while the Falcon tracks current draw during GPS fixes, which may slightly delay the alert.
Backup Battery Alerts
Backup batteries play a crucial role in maintaining communication during power interruptions. These batteries keep trackers operational even after power loss, ensuring location data continues to transmit despite tampering. High-end devices can enter a deep-sleep mode, drawing as little as 10 μA of power, allowing them to remain functional for over 10 years until reactivated. Additionally, if cellular connectivity is disrupted during a power loss, some advanced trackers store events and location data in internal flash memory. Once the connection is restored, they upload the stored information, providing a detailed record of tampering attempts.
Setting Up Tamper Alerts with Piritiz Tracking Devices

Configuring Alerts Through the Piritiz Mobile App
To set up tamper alerts, start by purchasing a Piritiz tracking device for $19.95 and selecting a subscription plan, which begins at $7.00/month with a two-year prepay option. Next, download the Piritiz mobile app from the App Store or Google Play. Once you’ve installed the wireless tracker on your equipment, assign a unique name to each device. Specific names like "Flatbed 01" or "Excavator 3" make it easier to identify which asset is sending an alert.
The app offers around-the-clock visibility and sends instant notifications to your smartphone whenever it detects movement or tampering. You can also create geofences – virtual boundaries around areas like job sites or warehouses. If your equipment crosses these boundaries, you’ll receive an immediate security alert. This feature is critical, especially when considering that recovery rates for stolen trailers without tracking systems are less than 1%.
For quicker detection of tampering, enable Jostle Mode in the device settings. This mode uses an accelerometer to detect vibrations or movement immediately, without waiting for a GPS signal to confirm distance traveled. To avoid false alarms caused by minor vibrations, adjust the wake filter to trigger alerts only when the device detects at least one second of above-threshold movement within a four-second timeframe. Once the basic alert settings are configured, fine-tune your notification preferences for the best response.
Adjusting Alert Sensitivity and Notification Preferences
The Piritiz app allows you to customize notifications to balance responsiveness with practicality. For critical events like tampering or unauthorized movement, set the notification frequency to "Always" for real-time updates.
To avoid excessive notifications for less urgent events, use throttling options like "Not More Than Once Every X Seconds" or "Once Per Day" to limit how often alerts are sent. Additionally, you can filter out older alerts with the "Not If Older Than X seconds" setting, which is especially helpful if your device reconnects to cellular coverage after being offline and uploads stored data.
Lastly, enable low battery alerts to ensure uninterrupted operation of your tracker. While the batteries can last up to five years, Piritiz advises replacing them annually if the equipment is exposed to harsh temperatures.
Business Benefits of Real-Time Tamper Detection
Real-time tamper alerts, powered by advanced sensor technologies, offer businesses a powerful tool to safeguard their assets and operations.
Stopping Theft and Unauthorized Access
Equipment theft is a billion-dollar problem, with only 20% of stolen machinery typically recovered without tracking technology. Real-time tamper alerts change the game by instantly notifying you via SMS, email, or push notification when someone tampers with your equipment. These alerts provide immediate awareness of unauthorized handling.
For added security, you can customize alerts to monitor your assets during specific times – like nights or weekends – when equipment shouldn’t be in use. This level of control helps protect against external theft and internal misuse, which contributes to 30% of business bankruptcies and impacts countless tradespeople. In the unfortunate event of theft, real-time location data and movement logs give law enforcement the precise information they need to recover your equipment quickly.
Devices like Piritiz Tracking Devices simplify this process with an intuitive mobile app and customizable alert settings, ensuring your assets remain secure.
Reducing Downtime and Disruptions
Tamper alerts help you act before theft or damage occurs, minimizing downtime by catching misuse early and preventing costly mechanical failures. GPS asset tracking has been shown to reduce losses by 90% and increase recovery rates to an impressive 94%.
Beyond security, consistent tracking enables predictive maintenance. With accurate engine hours and diagnostic data, you can shift from reactive repairs to planned maintenance, extending equipment life by up to 35% and improving asset utilization by 40%. This proactive approach not only keeps your operations running smoothly but can also lead to insurance premium discounts of 12% to 22% for assets equipped with tracking and security features.
Piritiz Tracking Devices, known for their long battery life and reliable performance, ensure uninterrupted tracking to support these benefits.
Better Asset Monitoring and Control
Tamper detection ensures that your GPS devices remain operational, providing continuous and accurate monitoring data. This eliminates gaps in visibility – those "dark" periods where assets might disappear from your dashboard during transit or off-hours. With 24/7 tracking, you maintain a clear view of job sites and supply chains. It also discourages unauthorized behavior, like employees avoiding surveillance or taking unapproved routes.
A centralized dashboard transforms these alerts into actionable insights. Managers can oversee hundreds of assets simultaneously, responding to potential issues in real time rather than discovering problems days later. This integrated approach enhances efficiency and strengthens asset management.
