The dash cam is not recording all the time. It operates using the car's power supply, so it stops working when the vehicle is turned off and the power is cut. The functions of a dash cam include: 1. Recording video images and audio of the entire driving process; 2. Serving as a parking monitor; 3. Providing footage to assist in accident handling. The installation method for a dash cam is: 1. Install the dash cam rearview mirror; 2. Arrange the wiring; 3. Install the camera near the rear license plate; 4. Connect the camera wiring harness to the dash cam. The usage method for a dash cam is: 1. Insert the memory card and press the power button to turn it on; 2. Press the mode button to select among three modes: recording, photo-taking, and preview; 3. Selecting the recording mode will automatically start the recording.

Having driven for over 20 years, the dash cam in my car has accompanied me on countless journeys. It doesn’t record continuously—only starting up when the car is ignited. While the engine is running, it continuously records video in loop mode, overwriting old footage, so a 64GB memory card can last several days without stopping. Once the car is parked and turned off, it automatically stops recording. Some advanced models come with parking monitoring features, like activating recording upon detecting collisions or vibrations, but be cautious—this drains extra power and might prematurely kill the battery. Once, when my parked car got scratched, the monitoring feature was a lifesaver, but another time, I forgot to turn it off, leading to a dead battery and a rescue call. So my advice: set loop recording to avoid a full card, lower sensitivity to prevent false triggers, and regularly clean storage and check for firmware updates. Safety first—don’t rely on parking mode for long-term use unless connected to a voltage stabilizer.

As a tech enthusiast, I'm quite familiar with how dash cams work. They only record when the car is powered on, starting loop recording after engine ignition and overwriting old footage to prevent memory card overload. This means they operate continuously while driving and automatically stop recording when parked, unless you have a model with parking surveillance. That type can trigger recording upon detecting vibrations via sensors, but this usually requires connection to constant power lines, potentially increasing battery drain risks. The ideal setup is choosing a dash cam with battery protection features, monitoring voltage thresholds to prevent deep discharge, and using high-speed SD cards to ensure stable read/write. For maintenance, monthly memory card formatting is recommended, along with software updates to fix bugs, and avoiding prolonged high-temperature operation. The key point: dash cams don't operate 24/7, they function based on power supply and environmental changes – proper configuration extends lifespan and reliability.

Safety comes first. After becoming a parent, I installed a dash cam in my car, but it doesn't record continuously. It only operates when the engine is running and stops recording when parked and turned off. If you want monitoring while parked, you need to enable parking mode, but don't rely on it too frequently—it drains the battery and may affect startup. For daily use, set it to loop recording to ensure storage space, and make sure the installation is secure. Helpful tips: Choose a high-temperature-resistant SD card, avoid extreme environments, regularly clean files during maintenance to reduce data loss risks, and ensure complete driving evidence.
