The reviewer found the standout feature to be the new STARVIS 2 IMX678 sensor paired with a 7-layer glass lens and F\/1.5 aperture, which delivers noticeably better night and high-contrast footage than typical dash cams. Setup is straightforward and the included 128GB SD card means the camera is ready to record right away.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSTARVIS 2 IMX678 sensor:\u003c\/strong\u003e Produces improved low-light capture so nighttime details and license plates are more legible than with older sensors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual true 4K recording:\u003c\/strong\u003e Both front and rear cameras record at 4K@30fps, giving high resolution evidence from both directions simultaneously.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHDR and WDR processing:\u003c\/strong\u003e Automatically balances bright and dark areas to retain detail in scenes with strong contrast such as tunnels and bright headlights.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree 128GB SD card included:\u003c\/strong\u003e The camera ships with a preinstalled 128GB card that supports several hours of continuous loop recording and reduces the risk of running out of space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5.8GHz WiFi 6 and app support:\u003c\/strong\u003e Faster wireless transfers and a mobile app let users view, download, and share clips without removing the card.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in GPS and parking monitoring:\u003c\/strong\u003e GPS logs speed and location for stronger incident context, while a G-sensor triggers emergency recording and time-lapse parking mode (hardwire kit required for constant power).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Dash Cam C4 is ideal for drivers who prioritize video clarity and night performance, such as professional drivers, frequent night commuters, and owners of high-value vehicles who want full coverage from both front and rear.
