- Low Light Performance: Good night vision for accidents after dark
- Parking Mode: Records while parked to catch hit-and-runs

Installation Considerations
Most rear dashcam installations require routing a cable from the front camera to the rear. The difficulty varies by vehicle—hatchbacks are easiest, while sedans may require removing interior panels. Many dual-camera systems come with extended cables and routing tools.
Video Quality for Evidence
When choosing a rear dashcam for accident protection, video quality matters. You need sufficient resolution to read license plates and identify vehicles. 1080p is the minimum we recommend, with 2K or 4K providing better detail for legal purposes.
Parking Mode Importance
Many rear-end accidents happen while parked—hit-and-runs are common. A dashcam with reliable parking mode will record these incidents even when you're not in the vehicle, providing crucial evidence for insurance claims.
Final Thoughts
A rear dashcam is an investment in protection. While front cameras are important, rear coverage is essential for the most common type of collision. Choose based on your video quality needs, installation comfort, and budget.
