Frequently Asked Questions (FAQ)
-
Q: How does the remote engine cut-off function work? Is it safe while driving?
-
A: The fuel/power cut-off command is transmitted instantly via our app or SMS. For absolute safety, the system is engineered with an intelligent threshold: if the vehicle is traveling at high speeds, the engine will only immobilize once the vehicle drops below 20km/h or comes to a complete stop, avoiding highway accidents.
-
-
Q: Can we monitor thousands of T400 units under one single management platform?
-
A: Yes! We specialize in B2B volume deployments. We can configure dedicated private sub-accounts for fleet operators and leasing agencies, enabling centralized monitoring of your entire enterprise fleet on a single master dashboard.
-
-
Q: What happens if thieves cut the vehicle's main power supply to disable tracking?
-
A: The T400 is equipped with an internal backup battery. The moment main power is disconnected, the device instantly transmits a "Main Power Disconnection Alert" to your phone and continues tracking your asset using its internal power reserves.
-
-
Q: Can we integrate the T400 with our own existing corporate tracking software?
-
A: Absolutely. For clients utilizing proprietary tracking servers or third-party software, we gladly share our open API protocols and communication data formats to facilitate seamless backend integration.
