Parking monitor settings enable recording while parked. Users can also format the Micro SD card and adjust the LCD screen brightness within the menu.
Recording Modes Explained
Chortau dash cams offer versatile recording modes. Standard recording continuously captures footage while driving. Loop recording automatically overwrites the oldest files when the Micro SD card is full, ensuring continuous operation. The integrated G-sensor detects impacts and automatically saves the associated footage as an “event” file, preventing overwriting.
These incident recordings provide crucial evidence; Utilizing these modes, alongside features like WDR, guarantees comprehensive coverage. Proper configuration of these settings is vital for optimal performance and reliable evidence capture during incidents.
Standard Recording Mode
Chortau dash cams’ standard recording mode is the default setting for continuous video capture while driving. This mode constantly records footage onto the installed Micro SD card, providing a comprehensive record of your journeys. The front camera, boasting 1080P resolution, clearly captures license plates and road details.
Combined with the waterproof rear camera, standard recording offers complete vehicle surveillance. Ensure a formatted SD card is inserted for uninterrupted recording. This mode is fundamental for documenting driving conditions and potential incidents.
Loop Recording Functionality
Chortau dash cams feature loop recording, a vital function for continuous operation. When the Micro SD card reaches full capacity, the oldest footage is automatically overwritten with new recordings, ensuring you never run out of storage space; This seamless process guarantees constant surveillance without manual intervention.
The B-T25 and similar models utilize this feature to maintain a rolling record of your drives. Configure loop recording duration within the dash cam’s settings to suit your preferences, typically in 1, 3, or 5-minute intervals.
G-Sensor and Incident Detection
The Chortau dash cam’s built-in G-Sensor detects sudden impacts or collisions while driving. Upon impact, the camera automatically locks and saves the current footage, preventing it from being overwritten by loop recording. This crucial feature preserves evidence in case of an accident or incident.
Sensitivity levels for the G-Sensor are adjustable within the dash cam’s settings. Higher sensitivity detects even minor bumps, while lower sensitivity focuses on more significant impacts. This ensures relevant footage is always securely stored.
Front and Rear Camera Configuration
Chortau dash cams, like the B-T25, often feature a dual-camera system for comprehensive recording. Mounting the front camera securely on the windshield is essential, ensuring a clear view of the road. The rear camera, typically waterproof, should be positioned to capture the rear view and license plates.
Proper adjustment of both cameras is vital for optimal footage. Ensure the lenses are clean and aimed correctly. The rear camera’s cable should be routed discreetly to avoid obstructing the driver’s vision. Secure all connections for reliable operation.

Mounting the Front Camera
Securely attaching the Chortau dash cam’s front camera is crucial for optimal performance. Utilize the provided suction cup mount, ensuring the windshield surface is clean and dry for a strong adhesion. Position the camera high enough to provide a clear, unobstructed view of the road, avoiding obstructions like the rearview mirror.

Adjust the camera angle after mounting to capture license plates and road signs effectively. Tighten the mount securely, but avoid over-tightening. Regularly check the mount’s stability to prevent detachment during driving.
Installing and Adjusting the Rear Camera (Waterproof Feature)
The Chortau dash cam’s rear camera is designed with a waterproof feature for versatile placement. Mount it on the rear windshield or near the license plate, ensuring a clear view of the road behind your vehicle. Route the rear camera cable carefully, concealing it along the vehicle’s interior to avoid interference.
Adjust the rear camera angle to maximize coverage. The waterproof design allows for exterior mounting, but ensure secure attachment. Regularly inspect the cable for damage and ensure a watertight seal if externally mounted.
Advanced Features and Settings

Customize recording resolution, enable G-sensor sensitivity, and adjust loop recording duration. Explore options for timestamp settings and screen saver preferences. Proper configuration maximizes the dash cam’s functionality, providing comprehensive protection and peace of mind while driving.
WDR (Wide Dynamic Range) Adjustment
WDR, or Wide Dynamic Range, is crucial for optimal video quality in challenging lighting. The Chortau dash cam utilizes WDR to balance bright and dark areas within the frame, preventing overexposure or underexposure. Access the WDR setting through the dash cam’s menu.
Adjust the WDR level – typically Auto, On, or Off – based on your driving environment. ‘Auto’ dynamically adjusts, while ‘On’ provides a fixed enhancement. Experiment to find the setting that delivers the clearest footage, especially during sunrise, sunset, or when entering tunnels.
Parking Monitor Mode Setup

Chortau dash cams offer a Parking Monitor mode, enhancing security while your vehicle is parked. This feature requires a hardwiring kit (sold separately) to continuously draw power from the car battery. Navigate to the settings menu and enable Parking Monitor.
Configure sensitivity levels to detect motion or impact. The camera will automatically record if triggered, providing evidence of incidents. Ensure proper hardwiring installation to avoid battery drain. Review recorded footage regularly to verify functionality and adjust settings as needed for optimal performance.
Troubleshooting Common Issues
Chortau dash cam experiencing problems? If the camera isn’t recording, check the power connection and ensure a formatted Micro SD card is inserted. For SD card errors, try reformatting the card using a computer or replacing it with a new, compatible card.
If footage is unclear, adjust the WDR settings or clean the lens. Ensure the camera is properly mounted and the view isn’t obstructed. Consult the manual for specific error codes and solutions. Contact Chortau support if issues persist.
Camera Not Recording
If your Chortau dash cam fails to record, first verify the power connection is secure. Ensure the unit is receiving adequate power, especially during vehicle startup.
