For the convenience of travel, many people choose to buy a car and configure a driving recorder after purchase. On the one hand, it is to protect the legitimate rights and interests of oneself, to better restore the real situation in the event of an accident, and to provide evidence for the judgment of the accident; Provide security guarantees, effectively prevent violations, touch porcelain and other situations.
There are many types of driving recorders on the market, such as rear-view mirror type, hidden type, screenless type, and special type for special vehicles. And there are also many functions of the driving recorder, such as high-definition video recording, emergency recording, assisted driving, night vision effects, recording and so on. In order to prevent the driving recorder from malfunctioning due to high temperature, it is necessary to add an NTC thermistor for temperature protection, temperature monitoring and temperature control. At present, the development trend of driving recorders is compact and hidden. Therefore, most manufacturers will use SMD NTC thermistors for temperature monitoring in driving recorders because of their small size, no leads, high precision and high cost performance. , suitable for high density surface mount.

The SMD chip NTC thermistor is generally welded on the printed circuit board of the driving recorder, and real-time temperature monitoring is performed during the working process of the driving recorder. When the external temperature affects the work of the driving recorder, the thermistor will play its role in temperature protection to prevent the printed circuit board of the driving recorder from failing due to high temperature.
