A second set of eyes
on the back seat.
Beacon Eye pairs a small Bluetooth beacon on the car seat with an app on your phone, so you get an alert if you walk away while a child may still be buckled in.
Reminder aid, not a substitute for checking the back seat yourself.
How it works
Four steps, a couple of minutes, and you're set up.
Attach the beacon
Stick the small CR2032-powered beacon to the car seat. No wiring, no charging cables — the battery lasts months.
Pair with the app
Download the Beacon Monitor app (the companion app for Beacon Eye).Open Beacon Monitor on your phone and pair over Bluetooth Low Energy in under a minute.
Drive like normal
The app quietly monitors the connection in the background while you drive — nothing to check or start manually.
Get an alert if you walk away
If your phone moves out of range of the beacon while it's still in the seat, Beacon Eye sounds an alert.
Built to be forgotten about — in a good way
Beacon Eye is designed to disappear into your routine, not add another thing to remember.
Range-based alerts
Uses Bluetooth signal proximity (RSSI), not GPS or location tracking, to tell when your phone and the beacon have separated.
Months of battery life
Runs on a single CR2032 coin cell. No charging routine to forget.
Quiet by default
No setup steps before every drive — once paired, it just watches the connection in the background.
Privacy-respecting
No location history, no account required to use the core alert. Your phone and the beacon talk directly to each other.
Tamper-resistant mounting
Low-profile beacon designed to stay put on the car seat without getting in the way of the harness.
Built on proven hardware
Powered by a Silicon Labs BLE module, the same class of chip used across millions of certified Bluetooth devices.
Inside the app
Simple on purpose — three screens cover everything.
Safety & compliance
Beacon Eye is a reminder tool, not a substitute for checking the back seat yourself every time you park. Here's what's built into the hardware.
Button-cell battery warnings
Labeled and tested against the federal safety standard for products with coin and button-cell batteries, to reduce the risk of battery ingestion.
Secure, tool-required battery compartment
The battery compartment requires a tool to open, consistent with that same standard's construction requirements.
Certified radio module
Built on a pre-certified Bluetooth Low Energy module, used under its existing equipment authorization.
