Video Quality: Look for a dash camera with high-resolution video recording, preferably Full HD (1080p) or higher, to capture clear and detailed footage. 2. Field of View: Consider the camera's field of view (FOV). A wider FOV covers more of the road ahead and provides better context in case of accidents or incidents. 3. Low-Light Performance: Check how well the dash camera performs in low-light conditions and at night, as this is essential for capturing quality footage in all lighting situations. 4. GPS Functionality: Some dash cameras have built-in GPS, which can record the vehicle's speed and location, providing valuable data for accident reconstruction. 5. Loop Recording: Ensure the dash camera supports loop recording, which overwrites old footage when the memory card is full, so you don't have to worry about manually deleting files. 6. G-Sensor: Look for a dash camera with a G-sensor (or accelerometer) that automatically detects collisions and locks the recorded video to prevent it from being overwritten. 7. Parking Mode: Consider dash cameras with parking mode, which can monitor your car while parked and record any impacts or incidents even when the engine is off. 8. Screen Size and Interface: Check the size and usability of the camera's display. A larger screen and user-friendly interface make it easier to review footage and adjust settings. 9. Wi-Fi or App Connectivity: Dash cameras with Wi-Fi or companion apps allow you to view and download footage directly to your smartphone or tablet for convenience. 10. Memory Card Support: Verify the type and capacity of memory cards supported by the dash camera. Class 10 microSD cards are commonly used for reliable recording. 11. Brand Reputation and Reviews: Research the brand's reputation and read user reviews to ensure the dash camera is reliable and performs well over time. 12. Budget: Set a budget based on your preferences and needs. Dash camera prices can vary significantly, depending on features and video quality. 13. Mounting Options: Consider how the dash camera mounts to your windshield or dashboard to ensure it provides a secure and adjustable fit.
