piggybacking on this, when i searched for VIOFO A129 Plus Duo on amazon, it also shows the Pro Duo option, which is $195 instead of $150, for 4k instead of 2k, and advanced parking mode (15s before & 30s after event). is the upgrade worth the price increase?

edit: after reading a bit more in this thread, I'm leaning towards the A29 duo one instead, the current price on amazon seems to be lowest of all time too

Fitcamx for OE look and simpler installation, though I'm not sure if there's one for 2015 Prius: https://fitcamx.com/collections/toyota/products/fitcamx-dash-cam-for-all-toyota?variant=40634549764268&sca_ref=2842824.mQDF8mYfG6

Other dash cam I would recommend is Viofo A229 Duo or Vantrue E2 for dual channel; Viofo A139 Pro or Vantrue E3 for 3-channel (front, interior, and rear).
