Ⅲ.Function Description 

1. Forward Collision Warning (FCW)

When the speed of a vehicle exceeds 30 Km/h, the FCW module will begin to work. When the vehicle has a larger speed than a vehicle in front and is likely to collide with it,DB-A502 will send out a warning at most 3 seconds in advance and the warning sound will be “beep, beep, beep~”.

2. Urban Forward Collision Warning (UFCW)

When a vehicle runs at a speed of less than 30 Km/h and moves close to another vehicle in front, the device will send out a sharp warning sound “beep, beep, beep” before a possibly imminent collision.

3. Virtual Bumpers (VB)

The device will send out a warning sound “beep, beep, beep” before a collision with the vehicle in front possibly resulting from a very low speed (car sliding).

4. Headway Monitoring and Warning (HMW)

When the speed of the vehicle exceeds 30 Km/h, the HMW module will begin to work. When the distance from the vehicle to another vehicle in front reaches the set Level 1 minimum distance, the device will send out a warning to remind the driver of the vehicle in front and the warning sound will be “beep~”; and when the distance from the vehicle to another vehicle in front reaches the Level 2 minimum distance, the device will send out a warning sound “beep, beep~” to remind the driver of a too close distance and the warning sound will be repeated at an interval of 5s until a safe distance is restored.

Warning: No matter whether the device DB-A502 sends out a warning or not, you (the driver) will be solely responsible for keeping a safe distance from the vehicle in front.

5. Lane Departure Warning (LDW)

DB-A502 will start the LDW module when the vehicle speed is higher than 50 Km/h, and when the driver departs from the lane unintentionally, the device will send out a warning and the warning sound will be “ding~ding~”.

The LDW module will not send out a warning in the following cases:

the turn signal lamp or hazard flasher is turned on when changing the lane;

quick lane switching is performed;

the driver steps on the brake when changing the lane;

the driver changes the lane in an acceleration or a deceleration state;

lane lines are not marked or are not clear;

f. the speed is less than 50 Km/h;

under adverse weather conditions.

Driving Video Recording

DB-A502 can record 1080P HD videos and perform automatic cyclic recording every 3 minutes and store data into the high-speed class 10 SD card.

Emergency Lockout 

When the vehicle encounters severe turbulence or collision during traveling,DB-A502 can immediately lock the current video and will not delete it from cyclic recording.

8. Driving Behavior Detection

The DB-A502 can detect the Rapidly Speeding-up, Hard Braking, and High-speed Turning of the vehicle through built-in sensors.

9. Video Output

DB-A502 supports video output in CVBS format, or support the PAL (default) or NTSC system for video recording by DVR.

10. Volume Adjustment

The volume can be lowered or increased by repeatedly pressing the button (-) or (+) on the side of the product, respectively; and the volume is at five levels of from 1 to 5.

11. Serial Port Communications

DB-A502 can support RS232 and can communicate with other devices to transmit vehicle information and various alarm information.

12. Signal Input and Output

DB-A502 has 3-way signal inputs which can be connected to the turn signal and brake signal.

13. Mobile APP Linkage

An Android Phone may install ROADRAGON APP in “Road-Defend” and may be connected to the WiFi hotspot of the device, and then real-time video viewing and requesting of videos under History on demand can be achieved.
