Specific Illustration：
(1)I.HI3521 System: including main control CPU, memory DDR3 and power management IC, realizes the smallest system running. It also has 8-channel AHD HD video access, which can expand the application of intelligent forward-looking function in the future.
(2)Power Supply Processing: realizes the conversion of automobile power supply into equipment usable power supply, including power supply anti-surge treatment, power supply filtering, power conversion, 24V to 12V power conversion is used for camera and other circuits. 24V to 5V : System 5 V. 5V to 3.3 V: System 3.3 V. 3.3 V to 1.2 V: 3.3 V to 1.5 V: DDR3.
(3)Video AD Conversion: the system supports up to 4-channel AHD1080P camera interface, and video AD chip is used for conversion in design.
(4)Camera Power Supply: the camera needs power supply, and 5-channel 5V power supply are provided externally.
(5)Hard wire detection interface: the reverse gear signal, left turn signal, right turn signal and ACC signal need detecting by the equipment.
(6)Infrared Interface: the equipment leaves an infrared interface for operating configuration parameters and receiving touch data during calibration. (7)Camera input: the device supports 4- channel AHD1080P camera input and camera missing detection.
(8)Video Output: supports CVBS, HDMI, AHD720P, AHD1080P, VGA to achieve HD images which are displayed on the central control display screen or connected to the DVR Video Recorder for recording.
