A CPL (circular polarizing) filter is a rotating lens filter that can cut certain types of reflections—mainly the shiny glare you get from dashboards and windshields in bright light. Here’s the part most accessory pages skip: a CPL is not a free upgrade. It trades light for reflection control. That trade can be worth it

Resolution is only one piece of video quality. At night, the limiting factors usually aren’t “how many pixels,” but how much light the sensor can capture per frame and how fast the camera can expose without smearing motion. License plates are a perfect storm target: they’re reflective, they’re often at an angle, and they move

Summer heat is a silent dash cam killer. Not because you “installed it wrong,” but because a windshield is basically a glass greenhouse that cooks anything stuck to it for hours. Most summer dash cam failures fall into two buckets: This guide focuses on practical, heat-safe fixes that hold up better than “re-stick it and

ADAS stands for Advanced Driver Assistance Systems. It’s the set of forward-looking safety features that help with lane guidance, braking support, and speed control.

The problem is simple: the dash cam keeps drawing power from your car battery. To prevent a dead battery, hardwire kits use a voltage cutoff.This shuts the

Few things are worse than finding your dash cam didn’t record an accident or close call. In real life, the main cause of “dash cam not recording” is usually the SD card. Cards wear out. Formatting gets ignored. Files get corrupted. This happens especially in hot cars where the camera records constantly. This guide explains
