According to the existing technologies the dash cam works by car battery and then records the video and sound of the vehicle through the camera. There are a lot of dash cams equipped with built-in sensor , so that the video will be automatically locked and when accident happens. however , a lot of drivers may have such doubt, can the dash cam continue to work when the power is cut off ? will the dash cam be out of power when the car is power off ? How can i maintain the consumption of dash cam ?
Normally, dash cam works by car battery in the daytime , so it will stop working after the car is power off . many dash cams are equipped with batteries , some batteries are used for up to four or five hours , while some batteries can only last about half an hour . therefore, the dash cam can continue to keep working during the day , but the dash cam also needs to have a rest due to the limit of battery
And how can dash cam work for 24-hours to meet our need ? It is an easy way to buy a portable power source so that the dash cam can be connected to the portable power source, and work for the whole day.
Some drivers want to install a on-board monitoring equipment which is feature-rich and also with anti-theft function, but its power consumption is far beyond the dash cam . some people want to modify the car circuit ,the electricity is directly imported to the battery, modify the car circuit to solve the night on-board monitoring power supply problem. It is dangerous for the car once the battery runs out. So installing a dash cam is better than installing a monitoring device.
