Server Room Protection in your data center with Door Detective from Smarter Security

Data Center Physical Security

Stop Insider Threats Before They Walk Through the Door

Your access control system knows who badged in. Door Detective® knows who actually walked through. Designed for the high-stakes demands of data center security, it automatically detects tailgating, piggybacking, and direction violations at every interior doorway in real time — no extra personnel, no gaps, no blind spots.

Why Traditional Access Control Misses Tailgating in Data Centers

Credential readers verify who presented a badge. They cannot verify that only one person passed through. Door Detective fills that gap — instantly, automatically, at every door.

Automated Protection
at Open Doors

Unlike turnstiles that control a dedicated lane, interior doors open freely once a valid credential is presented. Door Detective ensures that only one authorized person passes through per credential — in the approved direction — without requiring additional personnel.

Real-Time
Detection & Alerting

Identify violations as they happen — tailgating, piggybacking, loitering, door prop, and directional violations — the Door Detective immediately triggers alerts to your access control system and video surveillance, enabling rapid response before damage is done.

Powered by Neural
Network Technology

Door Detective uses advanced neural network intelligence to accurately classify people and objects in real time — minimizing false alarms while maintaining precise detection accuracy across the demanding conditions of a data center floor.

%
Insider threats are the leading source of data center breaches.
According to IBM research, 60% of cyber attacks involve insiders — and physical access is often the first step. The Ponemon Institute estimates the average data breach now costs $4.45 million. Door Detective addresses the physical access gap that traditional IT security tools simply cannot reach.

What to Know

Security FAQs

Have a question not answered here? Our team is available 24/7 to help you find the right Door Detective configuration for your data center environment.

Tailgating occurs when an unauthorized person follows an authorized credential-holder through a secured door without the authorized person’s knowledge or consent. Piggybacking is similar, but involves the authorized person knowingly allowing the unauthorized individual to follow them — often due to social pressure, courtesy, or collusion.

Both represent serious physical security vulnerabilities. Door Detective detects both scenarios and triggers alerts immediately, regardless of whether the unauthorized entry was intentional or incidental.

Door Detective is designed to integrate with your existing physical access control system and video surveillance infrastructure. It does not require replacement of your current platform — it connects alongside it, enhancing the intelligence of each door event with real-time occupancy and violation data.

For most data center server room applications, we recommend the Door Detective Classic, Plus, or SG model, depending on the doorway configurations. The Classic provides adjustable beams and anti-crawl protection, making it well-suited for standard server room doorways where precision tailgate detection (1.97″) and wide lane coverage (up to 98.4″) are needed.

For double-door entries, high-security colocation cages, or any environment where collusion among insiders is a specific concern, the SG model adds Sidegate® Detection and collusion-detection capabilities — the highest level of protection available in the Door Detective product line.

No. Door Detective is specifically designed to provide automated protection without additional personnel. It detects and alerts on violations in real time, sending notifications to your existing security operations team through integration with your access control and video surveillance systems.

This means you can protect more interior doorways with your current team, reducing cost per secured entry point without compromising detection accuracy.

Yes. All Door Detective models include lockdown capabilities, allowing your security operations team to rapidly restrict access across interior doors during an emergency event. The system can also be configured to respond to emergency status signals from your existing access control platform.

Supplemental access controls for Emergency Status are supported across all models, enabling automated responses to facility-wide security events without requiring manual intervention at each doorway.

Door Detective comes with a full one-year warranty, which extends to three years through Smarter Security’s site certification and training program. Adding the preventative maintenance program extends warranty coverage by an additional two years, resulting in up to five years of protection.

Smarter Security also provides lifetime remote support and 24/7 phone support — meaning your security team is never alone if an issue arises. Extended five- and ten-year programs are available; contact us for details.

Door Detective logs every access event, violation detection, and population count — creating an audit-ready record of physical access activity at each secured doorway. This event history supports compliance with SOC 2, PCI DSS, HIPAA, NIST 800-53, ISO 27001, and FedRAMP frameworks that require documented physical access controls and monitoring.

Because Door Detective operates as part of your integrated security platform (alongside access control and video surveillance), it contributes evidence across multiple control families in a single deployment.
