Thanks. I think I'll go with the veckle to give me options. Still need to figure out how parking mode works.
Depends on the camera.. but some, sense when there is no more movement and then switch to parking mode. Once the camera detects normal driving movement it goes back to normal recording.
What confuses most folk is that the camera is running continuously it is just the record (copy) to SD that differs. Consider your smart phone or camera.. as you frame a picture before taking it, only when you click the shutter does the picture get saved.
So in "normal" mode the camera is copying to the SD everything the camera sees. In parking mode it compares the current image to its previous image, if it detects a difference (from one frame to the next) it activates a process that goes back a few seconds in time from its internal buffer and saves the next bit of time (variable) to SD.. if there is no change it does not save it. The problem all cameras have in parking mode is how much of a difference there needs to be from one frame to the next.. clouds move, tree leaves rustle.. lights flash. Most cameras have some controls to select the sensitivity.. but parking mode in general leaves a LOT to be desired.
