New to 4G dash cams?

A dash cam with its own internet.

Most dash cams keep everything locked in the car — you find out what happened after it's too late to matter.

Your phone live view, anywhere you are

No SIM card to buy

The eSIM is factory-built-in. H2 finds the strongest local carrier on its own — pair once and it's online for good.

No phone needed in the car

H2 carries its own connection, so it stays online when you — and your phone — are miles away. That's the whole point.

Works offline too

No plan, no coverage, no problem — it keeps recording to the microSD card like any good dash cam. The 4G layer is yours when you want it.

Meet the H2

A guard, disguised as a dash cam.

Two cameras watch the road and the cabin. A 1 TOPS neural processor tells a passing shadow from someone testing your door handle. A built-in eSIM keeps it online coast to coast — so the moment something matters, your phone knows.

  • 1080p HDR road cam — plates readable in glare and headlights
  • IR cabin cam — rideshare trips and back seats, even in the dark
  • 2.99″ sliding display + five real buttons
  • Five-system GPS — routes, speed, and location on the map

AI Sentinel

Your car sleeps.
H2 doesn't.

Park and walk away — behind the windshield, H2 slips into ultra-low-power sentinel mode and keeps thinking all night.

01 / Watches

Records around the clock

Ultra-low-power AOV mode keeps a 1 fps timelapse rolling for 12, 24, or 48 hours — with low-voltage protection so your battery never pays the price.

02 / Thinks

Knows what matters

The onboard NPU tells a passing shadow from a real event. A bump, a break-in attempt — it switches to full recording and locks the clip.

03 / Tells you

Wakes you, not the thief

4G wakes up, the event uploads to the cloud, your phone buzzes. Watch live and decide what to do — from bed, from work, from another state.

The difference

Same windshield.
Different league.

Real life

For every time you walk away.

Not paranoia — just the quiet comfort of being able to look.

Our story

Good questions

Asked & answered.

Do I need to buy a SIM card?

No. H2 has an eSIM built in and connects to the strongest local carrier automatically. You manage the 4G data & cloud plan right in the AIDOVID app.

Will sentinel mode drain my battery?

Sentinel mode is designed for parking: standby draw is under 1 mA equivalent, and built-in low-voltage protection shuts monitoring down before your battery drops below a safe starting threshold.

Does it work without a subscription?

Yes — H2 records to its microSD card like a regular dash cam, plan or no plan. A data plan adds the remote layer: live view, event alerts, GPS tracking, and cloud backup.

Does it record audio legally?

Cabin audio can be switched off with one press of the mic button. Some US states require passenger consent for audio recording — check your local rules; video is generally fine.
