IIWEY 4K+4K Dash Cam Front and Rear - Dual 4K Protection

Our review of the IIWEY 4K+4K Dash Cam finds it best suited to drivers who want high-resolution, roundtrip coverage and reliable night performance. The single biggest reason to buy is the simultaneous true 4K capture from both front and rear cameras, which preserves finer license-plate and scene detail than mixed-resolution systems and can make a real difference when documenting incidents. Setup is straightforward, a 3 in IPS screen helps framing, and the included 64GB SD card means the camera is ready to record out of the box.

Key Features

• Dual 4K Recording: Both front and rear record in real 2160P simultaneously so details from both directions are captured with clarity for evidence or insurance purposes.
• STARVIS Night Vision: Advanced STARVIS sensors and f/1.6 apertures on both lenses deliver brighter, lower-noise footage in low light and rain for safer night review.
• 24-Hour Parking Monitor: When paired with the optional hardwire kit, the unit can monitor your vehicle with impact-trigger or time-lapse modes to protect the car while parked.
• 5.8 GHz Wi-Fi Transfer: High-speed in-camera Wi-Fi lets you download clips faster in the IIWEY app, reducing wait time when saving or sharing footage.
• G-Sensor and Loop Recording: The built-in G-sensor auto-locks impact clips to prevent overwriting while loop recording keeps continuous capture without manual file management.
• Ready Out of the Box: A 64GB SD card is included so users can start recording immediately without buying additional storage.

Who It's For

The IIWEY 4K+4K is ideal for drivers who regularly travel at night or in urban areas and want clear evidence from both front and rear cameras; taxi, rideshare, and fleet drivers will value the dual 4K coverage and STARVIS low-light performance. It also suits owners who want a straightforward setup with an included SD card and a visible 3 in display for quick playback.

Those who should look elsewhere include buyers who need a fully integrated hardwire kit in the box or who require a camera with proven long-term firmware stability for heavy continuous use; some owners have reported intermittent power-off issues, so users who need absolute plug-and-forget reliability without additional setup may prefer alternatives with long-established track records.
