Dash cams, or dashboard cameras, are small video cameras mounted on the dashboard or windshield of a vehicle to record the road ahead. They are increasingly popular for various reasons, including providing evidence in case of accidents, improving driving behavior, and enhancing overall road safety. Here are some key aspects about dash cams:
Recording Features:
Dash cams continuously record video footage while the vehicle is in motion.
Some models have loop recording, which means that when the storage is full, the oldest footage is overwritten by the newest, ensuring that the camera always has the most recent footage.
Resolution:
Dash cams come in various resolutions, typically ranging from standard definition (SD) to high definition (HD) and even 4K. Higher resolution provides clearer and more detailed footage.
Field of View:
The field of view (FOV) determines how much of the road is captured by the camera. A wider FOV is generally preferred to capture more details, but it can vary between models.
Impact Sensors and G-Sensors:
Many dash cams have built-in sensors that can detect sudden changes in speed or movement (such as during an accident). When such an event occurs, the footage is often protected from being overwritten.
Parking Mode:
Some dash cams have a parking mode that allows them to continue recording even when the vehicle is parked. This is useful for capturing incidents such as hit-and-runs or vandalism when the vehicle is unattended.
GPS:
GPS functionality is often integrated into dash cams, providing information about the vehicle's location and speed. This data can be useful for reviewing footage in detail.
Wi-Fi and Connectivity:
Many modern dash cams have Wi-Fi connectivity, allowing users to view and download footage directly to their smartphones or other devices.
Legal Considerations:
The use of dash cams is subject to legal regulations that vary by jurisdiction. It's important to be aware of the laws regarding recording in your area, especially with regards to privacy.
