Dash cams have become a must-have for modern drivers—offering protection, evidence, and peace of mind. But if you're new to the technology, you may find yourself wondering: What is a dash cam? How do dash cams work? What are they used for? In this complete guide, we'll cover everything you need to know, from how dash cams operate to their key features, benefits, and recommended models from AUTO-VOX.
1. What Is a Dash Cam?
A dash cam—short for dashboard camera—is a compact video recording device mounted on your vehicle's windshield or dashboard. Its main purpose is to record video footage of your driving journey, capturing incidents such as accidents, road rage, and even theft or vandalism.
Key Uses of a Dash Cam:
-
Record traffic events for insurance claims
-
Protect against false accusations
-
Capture unexpected incidents on the road
-
Monitor parked vehicles
Modern dash cams, like the mirror dash cam from AUTO-VOX, go beyond simple recording. They offer smart features like GPS tracking, parking mode, night vision, and more.
2. How Does a Dash Cam Work?
At its core, a dash cam uses a wide-angle lens and video sensor to continuously record footage to a memory card while you're driving.
Step-by-Step Process:
-
Power On: The dash cam turns on automatically when you start the car.
-
Video Recording: It records in a loop, saving video files in intervals (e.g., 1–5 minutes).
-
Storage: Video footage is saved on a microSD card.
-
Event Detection: Features like G-sensors detect impacts and lock important clips.
-
Optional Upload: Some models allow cloud uploads or app syncing.
AUTO-VOX dash cams come equipped with loop recording and emergency lock to protect your footage.
3. Types of Dash Cams
There are different types of dash cams depending on the features and installation method:
a. Single Lens (Front Only)
Basic setup that records from the front windshield.
b. Dual Lens (Front + Rear)
Captures footage from both the front and rear of the vehicle.
c. Mirror Dash Cam
A dual-channel camera built into a rearview mirror, such as the AUTO-VOX V5PRO.
4. Features to Look For in a Dash Cam
When choosing a dash cam, consider the following features to maximize safety and usability:
a. Loop Recording
Automatically overwrites old files so you never run out of space.
b. G-Sensor
Detects collisions and locks important files to prevent deletion.
c. Night Vision
Uses IR or high-sensitivity sensors to record clearly in low light.
d. Parking Mode
Records video while your vehicle is parked. Best used with hardwiring or an external battery.
e. GPS Tracking
Logs location and speed data for evidence or tracking.
f. Wi-Fi or App Control
Download footage and adjust settings via smartphone.
AUTO-VOX dash cams like the T9 offer these premium features while maintaining an easy-to-use design.
5. Do Dash Cams Record Audio?
Yes, most dash cams include a built-in microphone to record sound inside the cabin. You can usually turn this feature on or off depending on your privacy preferences.
6. Do Dash Cams Work When the Car Is Off?
This depends on how your dash cam is powered:
-
Cigarette lighter plug: Powers off with the engine.
-
Hardwired: Draws constant power, enabling parking mode.
-
Battery pack: Provides power independently without draining your vehicle's battery.
mirror dash cam models from AUTO-VOX support all of the above power options, making them flexible and secure for any use case.
7. Can a Dash Cam Drain My Car Battery?
When properly installed, dash cams use minimal power. But continuous use during parking mode without low voltage protection could drain your battery.
AUTO-VOX hardwiring kits include low-voltage protection to automatically shut off the camera before it impacts your car battery.
