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. IP69K Waterproof and Dust-proof Test.
7 QUAD DIGITAL Wireless TFT LCD Monitor X1. DIGITAL Wireless IR CCD Camera X4. Power cables for monitor and camera. This is a digital wireless camera system. It means only the signal is wireless.
The monitor and the camera do not have built-in batteries. They should be connected to power to work. What is the difference between analog wireless camera system and the above digital wireless camera system?
Both of them use the same 2.4GHz frequency technology. The 2.4GHz frequency is very common , many of our wireless device use this frequency, such as wireless router, bluetooth, etc.
So the analog wireless camera system sometimes receives signal wireless routers, bluetooth and cellphone, and interferenced caused. There is no other device can transmits the same digital signal as the camera. Digital Wireless QUAD Monitor Camera system.
