At present many car owners are worried about battery safety problem of car black box. This is because the car camera’temperature can reach 60 ℃ or more under direct sunlight, and such a high temperature deformation is likely to cause the battery to swell or even explode. Therefor, to solve this problem, the vehicle video recorder should use a super capacitor + depth gravity sensor technology to ensure that the video files won’t lost.and the chassis using Heat Resistant , UV PC + inner copper gall package, internally and externally to ensure the car camera dvr security, stability and smooth operation.
Super capacitors are polymer materials components emerging in recent years, its high temperature resistant long service life, stable performance and demanding production technology make it can be supplied by only a few large components manufacturers in Japan and South Korea. That is why the price of the Super capacitor are much higher than that of ordinary lithium batteries. Only a small number of industry-formal car dvr manufacturers will adopt it as a back-up battery.
