Can the OBD interface of the car be electrified? Does the long fire from OBD have any effect on ACC?

OBD can get electricity, which has an impact.

The driving recorder takes acc, and it is best not to take electricity from obd interface. Because the OBD is powered continuously, the recorder will always work, and it will record when parking and will not be turned off.

The load capacity of the power supply at obd is small, and some cars still supply power with the car power computer. If devices are added or their lines are short-circuited, the car will break down and should not be underestimated.

You can use the electricity from the skylight. If there is no skylight, use the electricity of the reading lamp in the car. So you can't see the wires after installation.

Extended data:

Driving recorder is an instrument to record the images and sounds of vehicles during driving. After installing the driving recorder, it can record the video images and sounds of the whole driving process of the car and provide evidence for traffic accidents.

Suggestion:

The camera has a larger shooting angle, which is conducive to comprehensively recording the situation around the vehicle. However, it should be noted that the angle of the lens should not be exaggerated to avoid distorting the picture.

The driving recorder should have good camera clarity and night shooting ability.

High definition is determined by the main control chip of the driving recorder. At this time, the owner needs to pay attention to what kind of image processing scheme the main control chip of the driving recorder is. In addition, the driving recorder should have enough storage space to realize long-term effective video recording.

Try to choose the one with good concealment, which can reduce the risk of broken windows being stolen.

The mainstream image processor formats are MOV and avi avi formats.

If the driving recorder does not reach 30 frames per second, the video will be stuck and not smooth in the photography mode of 1080P. In 720P photography mode, it takes at least 24 frames per second that human eyes can adapt to see smooth and clear video images.

With the mandatory installation of driving recorders on buses, buses and school buses, logistics and transportation companies have also begun to install driving recorders, and the products must be 3C certified.

According to the regulations of the national compulsory certification quality center, whether it is a driving recorder or a car black box. They must pass 3C certification before they can be sold. Therefore, buyers must choose carefully when choosing brands, and buy products produced by regular manufacturers with 3C certification to ensure safety.
