User guide

If you chose to obtain speed information from the vehicle, it must be connected to the speed

pulse sensor, which is used to calculate the speed ratio (coefficient = pulse/speed), the

pulse sensor is connected to the two wires SPEED-A and SPEED-B of our device, the speed

ratio will be measured according to the set speed and pulse during vehicle’s moving, which

is a little complicated to operate; simple wiring in Figure 3-5.

C: The acceleration alarm recording system menu – alarm settings – acceleration

Impact acceleration is set in three dimensions XYZ coordinate axis which can denote three

groups of statue. These are up and down, left and right, front and rear. The bouncing up and

down, acceleration, emergency brake, rollover, sharp turns etc. The threshold needs to be

set by an associated value, it is firstly needed a calibration after the installation onto the

vehicle. The calibration means to clear parameters X / Y / Z, secondly measure the allowed

range of emergency brake & acceleration & bouncing up and down as well as the change

value of a sharp turn of the vehicle during the operation, thereby to determine which axis’s

value changes. Once the system has been calibrated and the thresholds set, once the

vehicle exceeds these thresholds, the alarm will be opened.

D: Motion detection alarm recording System Menu – Alarm Settings – Motion Detection

Turn on the motion detection enabled switch, set the sensitivity level of high, medium and

low based on the need. General settings is medium, and the next step is mostly to stop the

sensing area of the motion detection, motion detection area will use diagonal set please

refer to Figure 4-30. As long as you set the motion detection area and set the video mode as

alarm recording, the image move will trigger the video to generate alarm-recording files

(Note: it can only take effect after setting and saving.)

5.4 PTZ

System Menu – Peripherals – PTZ Setting

Setup Steps: Firstly, select the PTZ protocol: divided into PELCO-D and PELCO-P protocol,

most people will choose PELCO-D.

Secondly, set the baud rate: there are four options 1200/2400/4800/9600, which must be

corresponded with the baud rate on PTZ.

Thirdly, Set the address code; directly input the address value corresponding with PTZ

setting, corresponding is required. Generally the defaulted PTZ address code is 1, PTZ

address code has an adjustable DIP, it is needed to set different address codes to identify

when there are many PTZs.

Fourthly, wiring: Connect control wire 485 on the PTZ to the RS485 – A positive pole,

connect the other one to the RS485-B negative pole.
