38 children die in hot cars every year. Every single one was visible from a parking lot. SeatSentry is being developed to alert the people walking past — not just the driver who already forgot.
If a parent is distracted, incapacitated, or has their phone on silent, those alerts go nowhere. The child stays in the car. The temperature keeps climbing. And the people who could help, the ones walking through the parking lot, have no idea.
of victims are age 3 or younger
of current alerts target the driver only
aftermarket products alert bystanders
Sensors monitor the cabin for occupant presence after the engine shuts off — detecting children, infants, and pets regardless of size or position.
Temperature and time thresholds trigger an escalating alert sequence. First alerts the driver. If no response, advances to the next level.
External alarm, flashing lights, and a visible display warn people in the parking lot that a child or pet is inside and needs immediate help.
They all alert the parent who already forgot. SeatSentry is the first and only system that alerts the people who can actually help.
Zero out of 6 aftermarket products alert bystanders. SeatSentry is the first.
| Product | Price | Alert Method | Bystander Alert |
|---|---|---|---|
| Ride 'n Remind | $275-$500 | Car horn (driver must press button) | Driver Only |
| Cybex SensorSafe | $300-$330 | Phone notification | Driver Only |
| STEELMATE | $86 | Dashboard display alert | Driver Only |
| Doona SensAlert | $49-$99 | Phone + emergency contacts | Driver Only |
| Infalurt | $273 | Key fob vibration | Driver Only |
| Payton's CHARM | $201 | Phone + 911 (never shipped) | Driver Only |
The pattern is clear: Every system relies on the parent who already forgot. SeatSentry breaks this pattern by recruiting the people outside who can take immediate action.
The child presence detection market is booming, but it's all focused on new vehicles and driver alerts. The aftermarket bystander-alert space is wide open.
