Full-time protection, front and rear. The VUEROID D21 4K pairs a true 4K front camera on a Sony STARVIS 2 sensor with a 1080p rear camera and built-in AI driver-assist alerts — so you're covered not just after something happens, but before it does. It's the dash cam for drivers who want sharp evidence, real collision warnings, and a parking mode that won't wreck their battery.

Crystal-Clear Coverage, Day or Night

• ✓4K UHD front camera on a Sony STARVIS 2 sensor captures license plates and road detail with real clarity, not guesswork.
• ✓1080p rear camera keeps an eye on what's behind you for rear-end collisions, tailgaters, and reverse-into-you parking lot hits.
• ✓165° front / 139° rear diagonal field of view — wide enough to catch the lanes beside you, not just what's dead ahead.
• ✓4K HDR + Ultra Night Vision balance bright sun and headlight glare while keeping footage usable after dark, when most dash cams turn to mush.
• ✓Ultra LP Capture is tuned specifically to read plates clearly, whether you're parked or moving.

Smarter Alerts Before Trouble Starts

• ✓AI ADAS with six alert types — including forward collision and lane departure warnings — give you a heads-up before a close call becomes a claim.
• ✓Speed camera notifications help you avoid surprise tickets on routes you don't drive every day.
• ✓3-axis G-sensor automatically detects impacts and locks that footage so it can't be overwritten by normal loop recording.

Watches Your Vehicle Even When You're Not

• ✓24/7 Parking Mode with motion detection, time-lapse, and sleep & wake-up automatically records impacts and suspicious activity while you're away.
• ✓Wakes and starts recording within 2 seconds of an impact, then switches straight to full 30fps footage.
• ✓Extreme low power draw (under 2mA) in standby means it can watch your vehicle for days without draining your battery — especially easy on hybrid and EV batteries.
• ✓-20°C to 70°C operating range and DC 12V-24V input mean it runs reliably through winter, summer, and in trucks or fleet vehicles, not just passenger cars.

Smart Features, Easy Install

• ✓Built-in GPS tags every clip with speed, location, and route for solid backup if you need to prove where you were.
• ✓Dual-band Wi-Fi + VUEROID app let you pull up and download footage straight to your phone, plus get software updates without extra cables.
• ✓Up to 256GB microSD support for weeks of footage before you need to think about it.
• ✓Hardwire kit and 6m rear camera cable included for a clean, hidden install front to back.
• ✓2-year warranty backs it up after the install is done.
