Latch
Blind, silent, uncompromising physical security.
A sealed, battery-powered sensor that knows the instant a door, cabinet, locker or container is opened, moved or struck — using no cameras and no microphones. It sends a push notification when real physical access happens. Nothing else. Nothing recorded.
The anti-camera
Surveillance cameras invade your privacy, need mains power and generate gigabytes of footage nobody watches. Latch is the opposite of that.
100% Privacy-First
No camera. No microphone. Latch protects your things without watching you do anything. It knows a door opened — it has no idea who walked through it, and no way to record it. Built for Airbnbs, rented rooms, shared offices and bedrooms.
Zero Subscription Trap
You do not become a hostage to a monthly bill. The local event log and BLE notifications work out of the box, free, for the entire service life of the device. Cloud is an option you choose — never a toll you pay to keep the hardware working.
2-Year Battery, Zero Wiring
Magnet-mount it in three seconds and forget it for two years. No cable runs, no drilling, no recharging every couple of months. One industrial lithium-thionyl chloride cell carries it through 12–24 months of real use.
Two sensors. No false alarms.
A passing truck shakes a door. A dropped bag knocks a cabinet. Motion alone cannot tell those apart from an actual opening — so Latch cross-checks the accelerometer against a barometric pressure step before it calls it an event.
Barometric spike (ΔP)
Bosch BMP388Opening a sealed door, container or cabinet produces a measurable pressure step. Latch sees that step — the physical signature of an enclosure being breached.
6-axis motion & shock
TDK InvenSense ICM-42688-PA microamp-class IMU running on hardware interrupt catches movement, tilt and impact without keeping the main processor awake.
Tamper switch
Physical rear-cover switchTry to pry the device off its mount and it fires an alarm event immediately — before the sensor can be pocketed or disabled.
What's inside
Nine parts, one sealed disc — no wires leaving the enclosure
Latch in motion
Anything that should stay shut
If it opens, moves or gets hit, Latch will tell you
Front & back doors
Know the moment a door opens — without a camera pointed at your hallway.
Key boxes & lockers
Airbnb key safes, coworking lockers and staff cabinets, logged and alerted.
Containers & crates
Sealed shipping containers and tool crates, monitored on LoRa far from Wi-Fi.
Cabinets & storerooms
Pharmacy cupboards, server racks, stockrooms — anything that should stay shut.
Bill of materials
The parts we committed to — no placeholders, no “final spec TBD”
