About this item
  • 【4K Ultra HD Dash Cam for Clear Driving Evidence】Capture every drive in stunning 4K Ultra HD resolution with this dash cam for cars. From license plates and road signs to unexpected incidents, the high-resolution footage preserves sharper details when evidence matters most. Combined with a 140° wide-angle lens, this car camera expands road coverage and helps reduce blind spots for more complete protection on every journey.
  • 【Compact Mini Dash Cam That Won't Block Your View】Unlike bulky dashboard cameras, this mini dash cam features a compact, low-profile design that mounts discreetly behind your rearview mirror. The small dash cam body helps keep your windshield clear while maintaining a clean factory-style appearance, making it ideal for drivers who want reliable protection without sacrificing visibility.
  • 【Easy Installation for First-Time Dash Cam Users】Designed for quick and hassle-free setup, this dashboard camera includes a strong adhesive mount and an 11.48 ft Type-C power cable for flexible routing in most vehicles. The compact design simplifies placement behind the rearview mirror, while straightforward installation helps drivers get recording faster without a complicated setup process.
  • 【Enhanced Night Vision for Day & Night Clarity】Featuring an F1.55 large aperture, WDR technology, and advanced 3D noise reduction, this night vision dash cam helps improve image brightness and reduce glare from headlights. Capture clearer footage on dark roads, in tunnels, during rainy weather, and in other low-light driving conditions.
  • 【Accident Protection, Parking Monitor & WiFi Control】G-sensor emergency recording automatically locks important footage during impacts, while parking mode helps monitor your vehicle when unattended. Built-in WiFi allows quick access to videos through the app for viewing, downloading, and sharing. (Hardwire kit required and sold separately.)
  • 【18-Month Warranty & Responsive Customer Support】Enjoy added peace of mind with an 18-month warranty and dedicated customer support. Whether you need help with installation, app connection, setup questions, or troubleshooting, our team is ready to assist. Optional in-person installation service is available at our New York and California service centers (installation fee only).

Is there a straightforward way to search which units have super-capacitors, or how to check short of a taking them apart?

This particular model claims an operating range of -20C to 60C which is probably as realistic as their "4k" sensors.

Been with 3 of their dashcams and saved me proof from an accident. It's a need for any vehicle. Never had any problems, even one of my vehicle is outside 24/7 close to 5 yrs..
