Frequently Asked Questions

Q: How does the rapid acceleration and deceleration alarm work?
A: When vehicle speed increases or decreases rapidly (e.g., sudden braking or pedaling), the device reports via SMS/call. Default detection is 3s, adjustable from 1-30s, with speed changes set between 10-255km/h.
Q: What triggers a sharp turn alarm?
A: It triggers when a vehicle makes a sharp turn. The default driving threshold is 20km/h (range 10-100km/h) and the turning angle can be set from 15° to 90°.
Q: How sensitive is the collision alarm?
A: The default trigger value is 96. The setting range is 1-255; the lower the value, the easier it is to trigger an alarm via SMS or phone call.
Q: What is the supported voltage range for installation?
A: The device supports a wide voltage input range of DC 9V to 90V, making it suitable for various vehicles including e-bikes, motorcycles, cars, and heavy trucks.
Q: Does the device have a backup battery?
A: Yes, it includes a built-in 55mAh/3.7V backup battery to ensure a power failure alarm can be sent if the main power source is disconnected.
Q: Can I customize the platform or product logo?
A: Yes, OEM/ODM services are available, including custom product colors, logos, specialized functions on the platform, and custom SIM IOT card integration.
