The keys came back. Did everyone leave?
Self-guided touring removed the onsite agent — and the person who used to notice a propped door or a visitor who never left. Unit Guardian confirms a show unit is actually empty once the keys are returned, and alerts your team the moment it isn't.
Nobody's watching the empty unit anymore.
Virtual tours and AI-guided leasing are efficient — but they removed the one person who'd notice something wrong on the property. Access that used to be supervised now isn't.
Tour, then leave
A prospect releases the keys from a digital lockbox, tours the unit, returns the keys, and leaves. The unit goes back to vacant and secure.
The overstay
They prop the door open — or leave someone inside — return the keys to look clean, then come back. Now the unit is a place to sleep, shower, do laundry, or worse, and no one on your team knows.
It reconciles the keys with the unit.
The trick isn't just "is there motion" — a vacant unit has sunlight and HVAC. It's motion when the keys say the unit should be empty.
Arm
When the keys are returned, the unit is set to "should be vacant" — manually, or automatically from the lockbox event.
Detect
A door sensor and a motion sensor watch the unit. If the door opens or someone's inside after it's been armed, that's a flag.
Alert
Your team gets an instant notification — the same trusted alerting behind our PanicTap platform — so someone can respond before it becomes a problem.
Two sensors, one answer
A door/entry sensor catches propping and re-entry; a motion/presence sensor catches someone still inside. Together they cut false alarms and catch what a single sensor would miss.
Set up a unit in minutes. Move it just as fast.
Show units rotate, and leasing can't wait on an electrician. Unit Guardian goes up — and comes down — in one quick visit.
Installs in minutes, no tools
No wiring, no electrician, no drilling into a unit you're trying to lease. Place the sensors, arm the unit, done.
Peel-and-place mounting
Sensors mount without damage and come off clean when it's time to move.
Re-deploy the same day
When your model unit rotates, the whole kit moves with it — set up the new unit in a single visit.
No wifi? No problem.
Unit Guardian runs entirely on cellular — nothing to plug into an internet connection, no network to configure, no wiring. It works in a vacant unit with no wifi at all, and there's nothing for your team to set up.
Buy it once. No monthly fees.
Unit Guardian is a one-time purchase per show unit — a capital expense you fund from reserves, not a recurring operating cost that drags on NOI every month. The way owners and holding companies prefer to fund it.
Door sensor, motion sensor, and hub — plus alerts to your team, included. Move it to a new unit anytime, at no extra cost.
