Many customers ask about installing 2 channel dash cams on a vehicle with a rear liftgate/hatchback. While there are extra steps involved, it's definitely possible. A dedicated 2-channel dash cam offers front and rear protection in a simpler form factor than two separate 1 channel systems and records footage onto one MicroSD card.
The installation process is significantly more difficult than regular vehicles without this design because the rear window where the camera is mounted actually lifts up and down rather than stay in a fixed position on most sedans and coupes. Some customers are perfectly happy having the wire dangle between the headliner and the liftgate but for those who want the cleanest install, the best way is to go through the hoses between the chassis and liftgate. If there is any trim on the liftgate, it's best to remove them to hide the rear camera cable under. See our Lexus NX Installation video for context.
