Overview of the IIWEY 4K+4K Dash Cam Front and Rear
The IIWEY Q7 dash camera is engineered for drivers who want complete visual coverage with no compromises in resolution.

True Dual 4K Recording: A Major Advantage
The defining feature of the IIWEY 4K+4K dash cam front and rear is its industry-leading dual 4K recording. Both cameras record at the same ultra-high resolution, ensuring uniform clarity regardless of direction.
Why True Dual 4K Matters
- Rear-end license plates are captured with greater clarity
- Fine details such as road markings and signage remain readable
- Zooming into footage retains usable detail
- Stronger evidence quality for insurance or legal disputes
In real-world scenarios such as hit-and-run accidents or aggressive tailgating, rear camera clarity can be just as important as front footage. By offering true 4K on both channels, IIWEY eliminates a common compromise found in many competing dash cams.
Wide 170° Viewing Angle for Maximum Coverage
The 170-degree wide-angle lenses on both cameras provide expansive road coverage without excessive distortion. This wide field of view allows the dash cam to capture:
- Multiple traffic lanes
- Adjacent vehicles
- Side-road activity
- Pedestrians near intersections
The result is more contextual footage that better represents what actually happened during an incident.
Dual STARVIS Sensors: Enhanced Low-Light Performance
Image clarity depends not only on resolution but also on sensor quality. The IIWEY Q7 dash camera features dual second-generation STARVIS sensors, paired with F1.6 large-aperture lenses on both cameras.
Benefits of STARVIS Sensor Technology
- Higher light sensitivity
- Reduced noise in dark scenes
- Improved contrast and color accuracy
- Clearer license plates at night
When combined with dual-channel HDR, the system effectively suppresses glare from headlights and streetlights, making night footage more usable and consistent.
Night Driving and HDR Performance
Night driving is one of the most challenging conditions for any dash cam. The IIWEY 4K+4K dash cam is optimized for these conditions through a combination of hardware and processing technologies.
Night Vision Strengths
- Balanced exposure in unlit areas
- Reduced headlight flare
- Improved plate visibility on dark roads
- Stable color reproduction
On poorly lit highways or residential streets, the camera maintains detail without introducing excessive grain or blur, which is essential for reliable evidence capture.
WiFi-6 Technology: Fast and Frustration-Free Transfers
One of the standout features of this dash camera is its 5G WiFi-6 connectivity, delivering transfer speeds of up to 20MB per second.
Advantages of WiFi-6 in a Dash Cam
- Significantly faster video downloads
- Smooth live preview on mobile devices
- Reduced waiting time for large 4K files
- More stable wireless connection
Using the dedicated mobile app, drivers can quickly preview footage, download clips, and share recordings without removing the SD card. For high-resolution dash cams, this level of transfer speed makes a noticeable difference in everyday usability.
