FAQ:4CH Mobile DVR with Ultrasonic Fuel Sensor
1. What is the 4CH Mobile DVR with Ultrasonic Fuel Sensor?
The 4CH Mobile DVR is a 4-channel vehicle surveillance system
designed for real-time monitoring and recording of video/audio
feeds. Integrated with an ultrasonic fuel sensor, it also tracks
fuel levels in real time, detects fuel theft, and monitors fuel
consumption.
2. How does the ultrasonic fuel sensor work?
The sensor uses ultrasonic waves to measure the distance between
the sensor and the fuel surface in the tank. This data is converted
into fuel level readings, providing accurate monitoring and alerts
for sudden fuel drops or unauthorized siphoning.
3. What vehicles is this system compatible with?
The system is compatible with most fuel tank types (metal or
plastic) and vehicles, including trucks, buses, construction
machinery, and fleet vehicles. Ensure the sensor is properly
calibrated for your tank dimensions during installation.
4. Can I install the system myself?
While basic technical knowledge is helpful, professional
installation is recommended to ensure proper placement of the DVR,
cameras, and fuel sensor. Incorrect installation may affect
accuracy or damage components.
5. How is the fuel data accessed and stored?
Fuel level data is stored on the DVR’s internal storage (SD card or
HDD) alongside video recordings. Users can access real-time data
and historical reports via the mobile app, web platform, or
directly from the DVR’s interface.
6. What alerts does the system provide?
Fuel theft alerts: Triggered by sudden fuel level drops.
Low fuel alerts: Activated when fuel falls below a user-defined threshold.
Tamper alerts: Sent if the sensor or DVR is disconnected or tampered with.
7. Is the system compatible with other sensors or cameras?
Yes. The 4CH DVR supports up to 4 cameras (e.g., IR, night vision,
or wide-angle) and additional sensors (e.g., temperature, GPS) via
available ports.
8. How accurate is the ultrasonic fuel sensor?
Accuracy depends on proper calibration and stable environmental
conditions. Typical margin of error is ±1–3% under normal operating
temperatures (-20°C to +70°C).
9. How do I maintain the system?
Clean the fuel sensor’s probe periodically to avoid debris buildup.
Check wiring and connections for corrosion or damage.
Update firmware via the manufacturer’s software.
10. What if the sensor stops working?
Step 1: Verify power and connections to the DVR.
Step 2: Reboot the system.
Step 3: Recalibrate the sensor using the provided software.
If issues persist, contact technical support.
Why Choose This System?
Cost Savings: Prevent fuel theft and optimize consumption.
