WARNING:
The 360° monitoring system is to be used as an auxiliary safety device. The vehicle operator
should be aware of his surrounding at all times! Please ensure you are familiar and comply
with local traffic and driving regulations.
CAUTION
Power
1. Supply DC 12/24V. Please check voltage before installing.
2. Please disconnect the power supply if not in use for a long period of time.
Safety
1.This ECU is design for indoor usage. To prevent from short circuit or being
shocked, please keep machine away from humid environments.
2.If any liquid or solid materials enter the machine, cut off the power
immediately. Please ask professional technicians to examine the unit before
it can be used again.
3.If any fault occurs, please ask a professional technician to examine or
contact your local distributor.
Installation location
1.Please install in a ventilated location to prevent the machine from overheating.
2.Keep the machine away from the radiator and exhaust area, or downpour, dust,
humidity, strong magnetic fields and places that will cause vibration or shock to
the machine.

1.While recording please ensure you are familiar and comply with local traffic and
driving regulations.
2.Without approval from our company, any refit or adjustment will void warranty.
The around view monitoring system provides high resolution images, which are captured from four
AHD camera's installed around the vehicle. It combines the surrounding images of the vehicle into
a vehicle virtual 360° birds eye view image. The system assists the operator to visually identify
obstacles in all directions of vehicle, it covers the blind - spots where accidents often happen. The
innovative 360° monitoring system simplifies the installation. All that is required are fixed dimension
mats, a small area and your vehicle dimensions to be input into the control box, the unit can auto
calibrate and will provide a 360° birds eye view image based on the values input.

2. CALIBRATION
2.1 Prepare work
a. Before setting, make sure you have got following calibration mats:
Mat A: 3.1m x 1.3m (figure 2.1-1)
Mat B: 5.6m x 2m (figure 2.1-2)

2.2. Calibration ground
a. Find a large space for calibration. Drive the vehicle in to the space. Make sure the corner of
vehicle can be seen on the screen.
b. Placement of calibration mats
Different types of vehicles have different length and width, so the placement of mats
is different. The usage conditions and placement methods have the following
restrictions:
Vehicle length is: 3.1m<length<6.0m
use 4x mat A
Vehicle length is 6.1m<length<13m
Use 2x mat A and 2x mat B

2.3. Setting and calibration
After the system is powered on and the around view system screen is displayed, press
the menu button on the remote control to enter the main interface for setting / calibration
(Figure 2.3-1). The software version number is displayed at the bottom. At this point,
press the center button to enter the around view settings menu (Figure 2.3-2).
After entering the menu, use the up, down, left, and right buttons of the remote control to
move the options or adjust the numbers, confirm the setting to enter the next menu.
Return button means to return to the previous menu, when the camera screen or around
view preview image is displayed on the calibration interface. Press the Menu button return
to the menu option.
Parameter setting menu
There are vehicle types, vehicle length, vehicle width, vehicle speed signal type and
vehicle speed frequency correction parameter you need to set.
You can choose bus or truck model to corresponding 3D vehicle model. (Figure 2.3-3
、Figure 2.3-4)

The setting range of vehicle length is 400~1300cm, The setting range of vehicle
width is 150~500cm (Figure 2.3-5、Figure 2.3-6)

frequency type
Note 1: During speed calibration, you need to select the vehicle speed calibration option
(Figure 2.3-9). Press the center button, then the system will start to capture the vehicle
speed frequency. When the vehicle is moving at 10 km/hr, confirm the calibration
option. Press the enter button (Figure. 2.3-10) in the calibration option to complete the
vehicle speed frequency correction. After the completion, move to the exit option
(Figure. 2.3-11) and press the enter button to leave the calibration function.
The type of vehicle speed signal can be either frequency type (HZ) (Figure 2.3-7)
or Duty Cycle (Figure 2.3-8), which are determined depending on the type of
speed signal provided by the vehicle. These need to be calibrated. If you cannot
determine the type of speed signal (note 1), you can use the GPS module.

Camera setting menu
There are camera types, camera installation height, camera position (POS X, POS Y)
parameter you need to set. Image rotation options are temporarily not set. There is
original view option below the interface in which you can check four installed
cameras. Make sure they are all set to CS30J (Figure. 2.3-12).

The actual value of the camera installation height and camera position POS X and POS
Y (Fig. 2.3-13) (note 2) need to align with the actual installation dimensions of the
camera.

You can enter the camera preview screen to check actual screen after installing
cameras. During the install of a camera, you need to adjust the elevation angle properly
so that the calibration cloth on the ground is close as possible to the reference line
(Figure 2.3-15~2.3.18), which will achieve the best stitching effect.

During automatic calibration (Figure 2.3-23), the system will perform image grab
feature points on its own. After the calculation (Figure 2.3-24), you can see the
stitching result of the 3D model and use the left and right buttons to switch ways of
presenting images in difference driving mode (Figure 2.3-25~33).

If the automatic calibration result is not good, you can use manual calibration method
(Figure 2.3-34) to set the four feature point positions required for the four camera
screens (Figure 2.3-35~39). After finishing the settings if you need to calculate the 3D
model, select this option (Figure 2.3-40). After the calculation is completed, the left and
right buttons can be used to switch the screen rendering modes in different driving
modes.
