Plan the mirror display and two recording views together
A mirror-format camera changes the display location as well as adding front and rear viewpoints. This model lists a twelve-inch screen and split-screen direction, with stated 170° front and 140° rear lens references. GPS supplies speed/location/direction information for supported recordings. Confirm the actual G840S model, mirror attachment and recording modes before purchase, then check rear-camera routing and parking-power requirements during installation.
A mirror-format display direction
The twelve-inch screen provides a defined display size to compare with the actual mirror area. Split-screen wording offers a way to view both camera directions, subject to the selected mode and installation.
Two lens-angle references
170° front and 140° rear supply numerical viewpoint directions for positioning the cameras. Check the actual frames after installation rather than treating the figures as elimination of every blind spot.
Recording context and file handling
GPS speed/location/direction and G-sensor locking add described information and storage roles. They give supported recordings a context and event-file workflow, with settings and regular backups managed through the manual.

Choose your setup
Confirm exact model/version, recording modes, card requirements, mirror fit and installation instructions. Keep airbags, controls and required mirror visibility clear. Obtain the parking-power and battery-protection requirements; time-lapse does not establish no power use or guaranteed uninterrupted 24-hour recording. Back up important files and continue normal reversing observations.
