For convenience, many people will choose to buy a car, and will be equipped with a dashboard camera after the purchase. On the one hand, in order to protect their own legitimate rights and interests, to restore the real situation in the accident better, to provide evidence for the accident judgment; On the other hand, it can be used as driving monitoring or parking monitoring to restrain car owners to abide by laws and regulations at the same time to provide protection for property safety and effectively prevent traffic violations, fake insurance claims and other circumstances.

There are many models of dashboard camera on the market, such as rearview mirror type, hidden type, no screen type, special car type and so on. Moreover, dashboard camera has many functions, such as HD video recording, emergency video recording, driving assistance, night vision effect, recording and so on. NTC thermistor need to be added for temperature protection, temperature monitoring and temperature controlling in order to avoid the abnormal operation of the dashboard camera due to high temperature. At present, the development trend of dashboard camera is small type and hidden type, so most manufacturers will adopt SMD type NTC thermistor for temperature monitoring in dashboard camera due to its small size, leadless, high precision and high cost performance, and is suitable for high-density surface mounting.

SMD type NTC thermior is typically welded to the printed circuit board of a dashboard camera for real-time temperature monitoring during dashboard camera operation. When the external temperature affects the operation of the dashboard camera, thermistor will play its role of temperature protection to avoid the failure of the printed circuit board of the dashboard camera due to high temperature.

SMD type NTC thermistor developed and produced by EXSENSE Electronics Technology Co., Ltd. plays an indispensable role in temperature protection and temperature monitoring in the dashboard camera due to its resistance value decreases with the increase of temperature, and vice versa.
