Point of view of this article: situation mentioned by subject is first to see if original car cigarette lighter will turn off power when key is in OFF position, and secondly to see if recorder turns off the parking control function, if yes , then there is no problem.
First, most current vehicle cigarette lighter power settings basically don't supply power when ignition key is in OFF position, so unless it's an older model, there's basically no need to worry about it. problem. Because if this is not case, then cigarette lighter is powered 24 hours a day, so if power of radio is connected to cigarette lighter at this time, then if radio is not turned off manually, radio will continue to work and consume energy of car battery, which is harmful to the battery.
Secondly, after eliminating above situation, most recorders now have a parking control function. In addition to need to connect to a normal live line on line (that is, 24/7 uninterruptible power), this also needs to be set in recorder. Understanding, main purpose is is that when vehicle is parked for a long time, if vehicle is hit to a certain extent, recorder will automatically start recording to record situation at time of collision, and it is convenient for owner to view. This function in principle does not pose a big problem in normal conditions. If it is parked in an open area and gets caught in heavy rain or hail, recorder will easily work due to a long impact, and standard battery will be exhausted.
I hope my answer helps you.
