Can I switch to parking mode manually ?

Currently, our dashcams do not support entering parking mode manually now,

while we do have customized features such as enter parking mode timer and parking Recording Duration you shall choose, and you can also set the protection voltage to avoid the dashcam from draining your car battery.

you shall refer to this article:
