Can my phone be used as a dash cam?

A mobile phone can serve as a temporary dash cam, but note that its functionality falls short of professional devices. To set it up, download a dedicated dash cam app (e.g., DailyRoads Voyager), then adjust parameters like resolution (recommended 1080P or higher) and loop recording duration. Mount the phone on the windshield near the rearview mirror, ensuring the lens has an unobstructed view and remains within the wiper-cleaned area. However, long-term use of a phone as a dash cam has significant drawbacks: continuous recording causes overheating, degrading battery life; the mounting bracket may detach during collisions; and in low-light conditions, standard phone cameras perform markedly worse than professional dash cams with Sony IMX415 sensors (e.g., the Iron General 4K model priced at ~RM164.22). For budget-conscious users, entry-level dash cams (e.g., a wire-free model at RM35.26) provide far greater reliability than phone-based solutions.
