It features SonyIMX323 with 1936 (H) × 1097 (V) active pixels, with pixel size of 2.8um, Novatek NT96655 with 128MB DDR3 SRAM and 2x 2.7V 3.3F super cap. It produces reasonable good quality video for most lighting conditions.
Recently, it kept resetting the time. And the dash cam does not record until the date/time is set. It is suspected that the time keeping battery is faulty. The coin battery appears to be FDR rechargeable lithium battery, ML621, 5.8mAh, 3.3V, 6.8x2.1 mm. The number of charge/discharge cycles are rated for 300 at 23C. The voltage at the end of capacity is about 2V and 2.5V at the half capacity. The standard charging method is constant voltage of 3V with 1KOhm.
The battery voltage is measured at 2.8V. Interestingly, the dash cam started working fine after it was opened and continued to work after it was put back. Perhaps something was shorting the battery?
