DashCam New Reviews That processor, which can range from a modest single-core chip to a powerful multi-core CPU in higher-end DashCam models, handles compression and features like time and date stamping, GPS overlay, and stabilization; a DashCam uses efficient video codecs to write continuous footage to the microSD card in short segments, often three or five minutes long, which makes file management simpler and reduces the chance of losing a long contiguous recording if something goes wrong. To protect moments that matter, a DashCam uses a G-sensor—an accelerometer that senses sudden deceleration or impact—to flag and lock the current video segment, preventing the DashCam from overwriting that file during loop cycling.
DashCam New Reviews Explaining how a DashCam actually works requires looking at several simple pieces working together: optics, an image sensor, processing, storage, and sensors that detect events and protect important files. A DashCam’s lens focuses light onto a digital image sensor—similar in concept to a phone camera sensor—where photons are converted into electrical signals that the camera’s processor reads and encodes into video files.
