This is the "soul" of the dash cam. It should achieve a 4K ultra - high - definition resolution (ensuring that license plates and road conditions are clearly distinguishable in details), and be equipped with star - light - level/ low - light night vision sensors. Even in scenarios such as no streetlights at night or when the tunnel has alternating light and dark, it can clearly record the pictures, avoiding the crucial pain point of "blurred footage with no evidence".
These are essential functions. It should support 24 - hour parking monitoring (powered by a step - down wire without draining the car battery), and at the same time have gravity sensors (automatically locking the video upon collision to prevent overwriting), which can effectively deal with situations such as the car being scratched while parked and malicious ，acting as an "invisible bodyguard" for the vehicle.
For the vehicle - mounted environment with high temperatures and vibrations, products with high - temperature - resistant bodies (not overheating and crashing on the center console in summer) and continuous loop recording without disconnection should be selected. Moreover, it must comply with traffic regulations (not blocking the line of sight, and the built - in battery/capacitor not being in violation), and be adaptable to different vehicle interfaces. It also needs to meet the compliance standards of overseas markets (in line with your product considerations for Amazon overseas sales)
