Proximity Evidence Technology

Be Less Watson
More Holmes.
The Secret Was Never Where. But Who Was There.

Sherlock solved cases by finding the clue everyone else missed. Digital Tripwire turns every object into a silent witness — capturing nearby phones and other device signals when something is touched, moved, opened, or taken.

The Problem
Trackers Tell You Where.
They Don't Tell You Who.

Your AirTag can tell you your bag is at a Starbucks on 5th Street. But the moment someone pulls it off and tosses it, you're tracking a trash can. It can't tell you who picked it up, when they touched it, or prove anything in court. That's the gap. That's what we built Digital Tripwire to fill.

What It Is
A Silent Witness
That Goes Anywhere

Digital Tripwire is a small, battery-powered device that passively logs every phone, watch, and Bluetooth device that comes within range. It doesn't track your stuff. It remembers who was near it.

When the accelerometer detects movement, it triggers a forensic-grade scan. Every device within 10 feet is logged with a MAC address, signal strength, distance estimate, and precise timestamp. Encrypted. Tamper-proof. Court-ready.

  • 3-5 year battery. No charging. Ever.
  • LTE-M cellular. No Wi-Fi needed.
  • AES-256 encrypted, hash-chained logs
  • Court-admissible evidence export
  • Grain-of-rice sensor nodes for expansion
The Node Ecosystem
Your Home. Protected
From the Inside.

Every object in your home becomes a silent witness. Nodes the size of a grain of rice, color matched with over 200 colors to choose from, embedded in the things you care about. Quietly connected. Always protecting.

How It Works
Three Steps. Zero Effort.

You don't need to be a tech person. You don't need to configure anything. You just place it and forget it.

1
Place It

Stick it in your car, your backpack, your kid's lunchbox, behind your TV. Wherever you want a silent witness. Peel. Stick. Done.

2
Forget It

The device sits dormant, sending a heartbeat location ping every 15 minutes. 3-5 year battery. No charging. No maintenance. It just watches.

3
Know Who

If something happens, open the app. Every phone that was near your item is logged with timestamps, signal strength, and distance. Export it. Hand it to police. Take it to court.

Personal Safety
She Didn't Check In
After Work

Before leaving the office, she set a 15-minute check-in. One tap in the app. Dark parking garages. Late night walks. Anytime she wants someone watching her back.

If she doesn't confirm she's safe within 15 minutes, her 5 trusted contacts are notified instantly with her location and full proximity logs, ready to export to police.

  • One-tap check-in timer
  • 5 trusted emergency contacts
  • Auto-alert with location + proximity data
  • Full log export for law enforcement
  • Works without Wi-Fi via LTE-M

Ownership Verification
They Can Strip It.
They Can't Erase It.

They chopped your car into parts. Changed the VIN. Sold it piece by piece at three different shops across two states. None of that matters.

Every Digital Tripwire device has a hidden UV-reactive QR code, invisible to the naked eye. Shine a blacklight, scan it with any phone, and it pulls up the registered owner, the full proximity log, and a chain of custody that holds up in court.

The parts don't need to be whole. They just need to be yours.

  • Invisible UV QR tied to your account
  • Works on individual parts, not just whole items
  • Links directly to the proximity evidence log
  • Scannable by any phone with a blacklight

FAQ
Frequently Asked Questions
How is this different from an AirTag or Tile?+
AirTags and Tile are finders. They tell you where something is. Digital Tripwire is an evidence device. It tells you who was near your item when it was disturbed. It logs every Bluetooth and Wi-Fi device in range, encrypts the data, and uploads it via LTE-M direct to the cloud. No phone relay required. Court-admissible forensic logs, not just a ping on a map.
Does it track in real-time?+
Yes. In Live Tracking mode, the device transmits its GPS location via LTE-M cellular. Even in dormant mode, it sends a heartbeat location ping every 15 minutes so you always know where the device is, even before an event occurs.
What data does it actually log?+
Every scan captures MAC addresses of nearby BLE and Wi-Fi devices, signal strength for distance estimation, device type classification, GPS coordinates, and precise timestamps. All cryptographically chained and encrypted before transmission.
Is this legal to use as evidence?+
Digital Tripwire captures publicly broadcast wireless signals, the same BLE and Wi-Fi advertisements every device around you is already transmitting. The data is collected passively, encrypted, and hash-chained for integrity verification. Our forensic architecture is designed to meet requirements for digital evidence admissibility.
Does it work without Wi-Fi?+
Yes. Digital Tripwire uses LTE-M cellular connectivity via a 1NCE IoT SIM to transmit data directly to the cloud. No phone relay. No Wi-Fi. No Apple Find My or Google network. Completely independent, which is exactly what makes it reliable as evidence.
Can law enforcement access my data?+
Your data is your data. You control it, you export it, you decide who sees it. If you choose to share logs with law enforcement, the chain-of-custody export provides forensic-standard documentation. We don't provide backdoor access to anyone.
What happens if I miss a check-in?+
If a scheduled check-in is missed, the app sends an immediate alert to your configured contacts with your last known location and full proximity logs. The missed check-in is logged as a timestamped event in the forensic chain.
