Large voltage spikes from the inductive generator(s) In automotive electronics, it refers to the disconnection of the vehicle battery from the alternator while the battery is being charged. Due to such a disconnection of the battery, other loads connected to the alternator see a surge in power line.
The peak voltage of this surge may be as high as 120 V and the surge may take up to 400 ms to decay. The transient high voltage which ususally occurs in automotive will damage the rear view camera system, if the system has no protection circuit. Our monitor uses a special component inside to avoid the damage. The transient high voltage will never damage our monitor. Following shows the test procedure.
Connect power supply to DC input of load dump generator. Connect output of the load dump generator to component power supply lines.
Set DC supply so that DC voltage to the component is 13.8VDC measured at the component. Chassis of DUT shall be physically isolated from the ground plane, and the DC supply should be electrically grounded to the ground plane.
After test our monitor has no damage at all. Electrostatic discharge (ESD) is the sudden flow of electricity between two objects caused by contact, an electrical short, or dielectric breakdown. ESD can be caused by a buildup of static electricity by tribocharging, or by electrostatic induction. ESD includes spectacular electric sparks, but also less dramatic forms which may be neither seen nor heard, yet still be large enough to cause damage to sensitive electronic devices.
Electric sparks require a field strength above about 4 KV/cm in air, as notably occurs in lightning strikes. Other forms of ESD include corona discharge from sharp electrodes and brush discharge from blunt electrodes. The ESD will do harm to rear view camera system if there is no ESD protection circuit. When user operate and touch the monitor, the high electrostatic voltage of 2kv/4kv/5kv/6kv/8kv will discharge between the user and monitor, and the high voltage will damage the monitor. The high electrostatic voltage will never damage our monitor.
Test methods: contact or air discharge are both acceptable. Isolate the DUT from ground-plate.
We apply the discharge of 2kv/4kv/5kv/6kv/8kv to every point that the user may touch when operating our monitor. After test, our monitor still work well, no damage at all.

Monitor bracket, 15m cable, Electrical connecting cable, Auto cigarette lighter adapter. 5 High Resolution Monitor with Digital Screen. Color CCD IR Side View Camera with Four Pin Screw Wateproof Connector, Connected Tightly, Never Loose. 15 meters' cable with 4 pin screw waterproof cable. Install the bracket on the monitor. Connect the split cable to the monitor as following. After connect well, connect the two Reverse signal cable CAM1 and CAM2 to the same reverse power of your car. Then install the monitor in a proper position in your cab. First, install the bracket of the camera. Then install the camera behind your car. You need to make a hole to fix the camera, and make another hole to let the cable get through.
Install the camera well, and now connect the cables. Connect the camera and extension cable as following. There are two cameras in the package. Connect one camera with the 15meters extension cable, then connect the extension cable to the connector of CAM1 (in yellow). Connect the other one with the other 15meters extension cable, then connect the extension cable to the connector of CAM2 (in red).
Last, connect the cigarette lighter adapter to the DC connector, and insert it to the car cigarette lighter. If have questions on how to install the system, please contact me!
