What does the screen saver of the dash cam mean?

The screen saver of the dash cam refers to the function where the screen of the dash cam can be set to turn black after a certain period of time, no longer displaying video content, and switching to recording in the background only. Generally, it can be set for 1 minute, 3 minutes, 5 minutes, etc. It is recommended to set the shortest time possible, as it can save more battery power. The purpose of the dash cam screen saver is that there is no need to look at the dash cam screen while driving. Staring at the screen during driving is dangerous, and the brightness should be adjusted to off. The functions of the dash cam: 1. It can provide evidence for traffic accidents. By replaying the recorded footage, the responsibility for the accident will be clear, and the traffic police can handle the accident quickly and accurately; 2. For those who enjoy self-driving tours, it can record exciting moments; 3. It can be used as a parking monitor.
As a long-time user of dash cams, I consider screen protection to be the function where the screen automatically turns off after parking, aiming to save power and extend the device's lifespan. I have a dash cam that always keeps the parking monitor on. Without screen protection, the screen stays lit all day, draining the battery very quickly. Once, after leaving it overnight, I almost couldn't start the car the next morning. Since then, I've set the screen to turn off after 5 minutes of inactivity, and it works great—no more issues. This also prevents screen burn-in, as LCD screens can age quickly if left on continuously. Additionally, having the screen dim while driving reduces glare and helps maintain focus. I recommend adjusting this function in your dash cam settings with moderate sensitivity—not too sensitive nor too sluggish. In short, it's a practical little feature worth enabling.
As someone who loves researching electronic devices, the screen protection feature of dash cams primarily works by using sensors to detect the vehicle's status and then turning off the display to save energy. The design intention is to reduce power consumption, especially in parking monitoring mode, where the device relies on the car battery. Keeping the screen on for too long would drain the battery quickly. The principle is simple: when parked, the motion sensor detects inactivity and automatically turns off the screen; it turns back on when the engine starts. This also prevents the device from overheating—continuous screen illumination in high-temperature summer environments can raise temperatures and accelerate component aging. I recommend adjusting the settings based on your driving habits, such as increasing sensitivity for frequent city stops and lowering it for long highway trips. The benefits are clear: it extends the dash cam's lifespan, saves on electricity costs, and indirectly protects the car battery. Proper settings can also enhance safety by avoiding distracted driving.
