Is this kind of parking mode something useful?

[Sam369]

Rexing S300+ and several other dashcams have the kind of parking mode which record at like one fps. I am not sure if they can automatically switch to the mode when car shuts down. Is this kind of parking mode new useful feature? Is one fps good enough when the car is parked? With the dual channel version, they claim that 63 hours of video clips can be stored on a 32 g card with the parking mode on.

I need to pay about $170 to get the dual channel version of Rexing S300+ from China. Is it worth that much? (Single channel version is about $300 on Aliexpress) I am Chinese, so I have no difficulty completing the transaction. Here is the link to the product.

I think its a okay way of saving space while parked, but i think 1 FPS might be a little too slow, i would use 2 FPS or 4 if it was a option in the settings.

I assume the camera still go into regular video recording if G-sesnsor is triggered ? but for the time between actual events a fjew FPS woul be fine for the not so important stuff.
