Getting started
Up in minutes.
Mount it
Electrostatic film on the glass, 3M bracket on the film — solid hold, clean removal, no residue. Behind the mirror is the sweet spot.
Power it
The included hardwire kit taps your fuse box so sentinel mode works while parked — 20–30 minutes for most owners, or any car audio shop. Prefer plug-and-play? The optional OBD module just plugs in.
Pair it
Install the AIDOVID app, scan the QR on the H2's screen, and the built-in eSIM takes it from there. App tour →
Install questions are covered in detail in the FAQ.
