Super Night Vision with WDR
Equipped with an advanced high-sensitivity sensor, six glass lenses, and a large f1.8 aperture, the dash cam captures clear and vivid footage even in low-light conditions. The 150° ultra-wide angle minimizes blind spots. WDR (Wide Dynamic Range) technology balances bright and dark areas in the footage, ensuring stable and clear video quality in varying lighting conditions.

Built-in GPS
The integrated GPS module records your exact driving route, location, and speed directly onto the video footage. This data can be viewed on your phone using the RoadRec app or on your PC/Mac using Sarmert's free GPS Player, providing essential evidence in case of an incident.

Seamless Loop Recording
The dash cam continuously records in loops. When the memory card is full, the oldest unlocked video files are automatically overwritten by new ones, ensuring uninterrupted recording. You can select loop recording durations (e.g., 1, 3, or 5 minutes) in the settings menu.

G-Sensor and Emergency Video Lock
The built-in G-sensor (gravity sensor) detects sudden impacts or collisions. When triggered, it automatically saves and locks the current video segment into an emergency folder, preventing it from being overwritten by loop recording. These locked videos serve as crucial evidence.

24-Hour Parking Monitor
With an optional hardwire kit (sold separately), the dash cam can provide 24-hour surveillance of your parked vehicle. It supports collision detection, motion detection, and time-lapse recording to capture events while your car is unattended. The dash cam will notify you audibly with a voice alert if an event is detected.

Headlights Reminder and Fatigue Driving Reminder
The dash cam includes intelligent reminders to enhance driving safety:
- Headlights Reminder: In tunnels or low-light conditions, the dash cam will remind you to turn on your headlights for added safety.
- Fatigue Driving Reminder: You can set the dash cam to alert you to take a break after 1, 2, or 4 hours of continuous driving, helping to prevent drowsy driving.

Screen Saver and Ergonomic Buttons
The screen saver function allows the display to automatically turn off after 1, 3, or 5 minutes (or be disabled) while recording continues in the background. This reduces distraction while driving. The dash cam features ergonomically designed buttons for easy access and control, including a dedicated button for emergency video locking.

Super Capacitor
The Sarmert C1 dash cam is built with a super capacitor instead of a traditional lithium-ion battery. This provides enhanced durability, extends the product's lifespan, and allows it to withstand extreme temperatures (from -4°F to 158°F), making it more reliable in various climates and safer against fire or explosion risks.
