Positive Proof door monitoring gives administrators a live view of every access point — alerting instantly when a door is propped open, forced, or left unsecured for longer than your policy allows.
THE PROBLEM
A Propped Door Is an Open Invitation
A May 2026 ALERRT Center study of 54 school active-shooter incidents found that 20 of the 29 doors attackers entered through (69%), classroom and exterior doors counted together, were unlocked, propped open or otherwise unsecured. Schools that rely on manual walkthroughs to check doors have a gap between rounds: a door propped open after one walkthrough can stay open, unnoticed, until the next. Positive Proof wireless door sensors give administrators a live dashboard of every campus access point with instant alerts for propped, forced, or held-open doors.
In most cases where an attacker got into a school space, the door was not secured. A May 2026 study by the ALERRT Center at Texas State University analyzed 54 school active-shooter incidents from 2000 to 2025 and found that 20 of the 29 doors attackers entered through (69%), classroom and exterior doors counted together, were unlocked, propped open or otherwise unsecured. Staff prop doors for convenience. Students wedge them open. Maintenance personnel leave them ajar. Without a monitoring system, administrators have no idea these vulnerabilities exist until something goes wrong.
The problem compounds with scale. A typical K-12 campus has dozens of exterior and interior access points — far too many for staff to physically check or monitor throughout the day. A manual door check shows each door only at the moment someone checks it, and how often that happens varies by state, district and school. A door propped at 10:15 AM may not be discovered until the next walkthrough — if it is discovered at all.
Beyond security, unsecured doors create compliance and insurance liability. Many state regulations and district policies require documented proof that access control procedures are being followed. Without an automated system logging door events, administrators cannot demonstrate compliance, respond to litigation, or provide law enforcement with accurate timelines when incidents occur.
A door is propped open for 45 minutes and an unauthorized individual enters campus undetected
An after-hours door breach occurs and is not discovered until the following morning
A district cannot provide law enforcement with accurate door event timelines during an incident investigation
A compliance audit reveals no documentation of access control procedures — creating policy and liability exposure
HOW IT WORKS
How Positive Proof Door Monitoring Works
From sensor installation to real-time dashboard visibility — every door event captured, every alert instant.
- 1
Sensors Install
Wireless door sensors install on every access point — exterior doors, interior corridors, restricted areas — without hardwiring or major construction. Most campus deployments complete in under a day.
- 2
Status Monitored
Every door reports its status to the Positive Proof platform in real time. Administrators see a live map of every access point — open, closed, secured, or in alarm — from any device.
- 3
Alert Triggers
When a door is propped beyond your configured threshold, forced open, or left unsecured, an instant alert goes to designated administrators. Alert routes are fully configurable by door type and time of day.
- 4
Event Logged
Every door event — open, close, alarm, resolution — is timestamped and stored in the audit trail. Exportable reports support compliance documentation and law enforcement requests.
WHO IT SERVES
Every Facility Where Access Points Create Risk

CAPABILITIES
Complete Visibility Into Every Access Point
Positive Proof door monitoring combines wireless battery-powered sensors, a real-time campus dashboard, configurable propped-door alert thresholds, forced entry detection, after-hours breach alerts, and a compliance audit trail. Sensors install on any door without hardwiring or construction — a typical K-12 campus deployment completes in under a day. The system integrates with most major access control platforms.

FAQ
Common Questions About Door Monitoring
Everything you need to know before requesting a demo.
No. Positive Proof door sensors are wireless and battery-powered. Installation requires no hardwiring, no conduit, and no major construction. Sensors mount directly to door frames and communicate wirelessly with the platform. A typical K-12 campus deployment completes in under a day.
An alert goes out when a door has stayed open past the limit set for it, and that limit is set door by door and by time of day. The alert identifies the door and goes by text, email, two-way radio or dispatch to the people you choose, who can differ after hours.
Yes. The system monitors door state continuously — not just open/close events. Administrators configure time-based thresholds by door type: an exterior door left open for more than 30 seconds may trigger an alert, while a main office door might allow 5 minutes before alerting. The system learns your operational patterns to minimize false alerts.
Positive Proof integrates with most major access control platforms. Integration allows door monitoring data to appear alongside access control logs in the Positive Proof dashboard. Integration scope is confirmed during the demo.
Access control decides who is allowed through a credentialed door. Door monitoring watches whether any door is standing open and alerts the moment one is propped, held, or forced. They cover different failure modes, and most schools need both. See the full door monitoring vs access control comparison. For a vendor-level comparison, see Positive Proof vs Verkada door monitoring. For the state requirements and the evidence behind locked doors, see the school door security guide.
Yes, when integrated with compatible access control and panic button systems. A door breach event can trigger automated alerts, PA announcements, and — when panic buttons are active — coordinate with the full emergency response protocol. Specific automation capabilities depend on your existing infrastructure.
The STOP School Violence Act of 2018 authorized the COPS Office to make awards to states, units of local government and Indian tribes to improve security at schools and on school grounds. Its School Violence Prevention Program funding is available for purposes that include locks, lighting and other deterrent measures, and technology for expedited notification of local law enforcement during an emergency, at K-12 schools. Check the rules of the program for eligibility and allowable uses before counting on it for a door monitoring project. See positive-proof.com/school-safety/grants-funding/ for details.
Locks only work when doors are closed and secured. A May 2026 ALERRT Center study of 54 school active-shooter incidents found that 20 of the 29 doors attackers entered through (69%), classroom and exterior doors counted together, were unlocked, propped open or otherwise unsecured, so the lock never came into play. Staff prop doors for convenience, students wedge them open, and maintenance personnel leave them ajar. Door monitoring addresses the behavioral gap that locks cannot: it detects when a secured door has been left open and alerts administrators before that vulnerability can be exploited.
