"A dual-camera system with ambitious specs for an impossibly low price."
The '2.5K front camera' spec means the device creates a 2560x1440 video file. This resolution is meaningless without a quality sensor and lens to provide actual detail, and at this price, it is unlikely to capture license plates any better than a well-engineered 1080p camera.
This product serves a user on an absolute minimum budget who wants the simple deterrent of a visible camera. It provides a basic recording function for undeniable, daytime incidents, making it marginally better than having no camera at all.
Anyone relying on a dash cam for clear evidence, especially at night or in challenging light, should allocate more funds. Users in climates with hot summers should avoid any camera that likely uses a lithium battery instead of a supercapacitor for safety and longevity.
