AI Overview
A car DVR (digital video recorder) lens is the crucial optical component of a dashcam that captures high-quality, wide-angle footage to record road, sound, and visual data. Key features include high-resolution imaging, 170-degree wide angles to cover multiple lanes, and night vision capabilities for improved low-light performance.
This video demonstrates the installation and features of a dual-lens car DVR:
Key Features of High-Quality DVR Lenses
- Wide-Angle View: A 170-degree viewing angle is standard for capturing a wide field of vision with minimal blind spots, suitable for most vehicles.
- High Definition & Resolution: Typical lenses support 1080P to 1440P high-definition video to capture critical details like license plates.
- Night Vision: Advanced coatings and larger apertures (e.g., F1.4 or F2.0) are essential for gathering more light, ensuring clear video during night driving.
- Dual-Lens Support: Many systems feature a front lens for the road and a secondary lens for the interior cabin or rear view.
Common Lens Specifications
- Focal Length: Fixed lenses (2.8mm, 4mm, 6mm) are common in, or for, surveillance systems, while car DVRs use fixed wide-angle lenses for optimal, consistent focus.
- Aperture: Smaller F-numbers (e.g., F1.4) indicate a wider aperture, which is better for low-light conditions.
Usage & Benefits
- Evidence Collection: A high-quality lens provides clear evidence in accidents.
- Parking Security: Enables features like parking mode to record, even when the car is off, if the sensor detects, for instance, a thief.
- Improved Clarity: High-quality lenses on sites like Alibaba.com can enhance the ability to read street signs.
