Can the Car Camera Monitor for 24 Hours?
3 Answers
Whether a car camera can monitor for 24 hours mainly depends on the power supply from the car battery or the standby duration of the built-in power source. As long as the car camera is connected to the car battery for power supply, such as through the reading light, it can achieve 24-hour monitoring. Below is more information about car cameras: Functions: Provides reliable evidence for the analysis and determination of traffic accidents. Allows drivers and passengers to view the situation inside the car. Offers a basis for handling issues such as disputes among passengers, lost items, and theft prevention. Monitors the environment inside and outside the vehicle, ensuring driving safety. Key Indicators: Clarity is one of the important metrics for evaluating a camera. Generally, products with higher clarity offer better image quality. Cameras with 420-line clarity have become the mainstream for rearview cameras, while those with 380-line clarity can also be a good choice if properly adjusted.
The cameras in my car can indeed monitor 24/7, but it depends on your specific settings. My parking surveillance mode operates on battery power and automatically starts recording upon collision detection. However, keeping it running all night can drain the battery, making it difficult to start the engine the next day. Newer models now feature low-power standby functions, using motion detection technology to save energy—only activating recording when there's movement in the frame. Storage capacity is also crucial; my 128GB card holds about three days of loop recording. Additionally, camera angles must consider privacy concerns—avoid pointing at neighbors' windows. Many regions now have regulations governing surveillance in public areas.
Last week, my car was scratched while parked on the roadside, but fortunately, the entire incident was captured by the camera. Nowadays, many vehicles support 24-hour monitoring, but it requires a constant power supply to achieve this. I've tested three mainstream dashcams and found that heat dissipation during continuous operation on hot days is an issue—the device casing gets extremely hot. Battery life is also a concern; older cars are better off with a voltage regulator to prevent battery drain. The motion detection mode is quite practical, as it only records when there's movement, saving significantly more power than continuous recording. However, its effectiveness diminishes in low-light conditions at night, so it's essential to choose a starlight-grade night vision camera.
