Tailgating Detection

Catch unauthorized vehicles following permitted ones through gates

What is tailgating detection in parking?

Tailgating detection identifies when an unauthorized vehicle follows a permitted vehicle through an access-controlled gate or entry point. ParkStash's Fixed LPR cameras scan both vehicles—if the second vehicle lacks a valid permit, an instant alert is sent to site management, enforcement teams, and towing companies for immediate action.

How does LPR tailgating detection work?

When a permitted vehicle triggers the gate to open, our Fixed LPR camera captures both the authorized vehicle and any vehicle following behind. The system checks both license plates against your permit database in real-time. If the trailing vehicle doesn't have a valid permit, an instant alert with photo evidence is sent to designated recipients.

Why is tailgating a security problem?

Tailgating bypasses your entire access control system. With fob-based or RF systems, anyone can follow a resident through the gate. This leads to unauthorized parking, increased crime risk, theft, and vehicles that shouldn't be on property. Traditional systems have no way to detect or stop this—LPR tailgating detection closes this security gap.

Who receives tailgating alerts?

You configure alert recipients based on your needs. Typically, site management teams, security personnel, enforcement staff, and towing companies receive instant notifications via email, SMS, or the ParkStash app. Each recipient can take immediate action based on the photo evidence provided.

Can tailgating detection work with my existing gate system?

Yes! ParkStash Fixed LPR cameras integrate with existing gate systems, fob-based access, RF transmitters, and card readers. The LPR adds a security layer on top of your current access control—you don't need to replace your gates or access hardware.

What happens after a tailgating alert is sent?

Alerts include photo evidence of both vehicles, timestamps, and license plate data. Site teams can immediately identify the unauthorized vehicle and take action—issuing a warning, citation, or dispatching a tow. The complete audit trail is logged for compliance reporting.

How accurate is tailgating detection?

ParkStash Fixed LPR cameras are trained on millions of license plates with 99%+ accuracy. The system reliably distinguishes between the permitted vehicle and any trailing vehicle, ensuring you catch unauthorized entries without false positives.

Does tailgating detection work at night?

Absolutely. Fixed LPR cameras feature infrared illumination for 24/7 operation regardless of lighting conditions. Tailgating attempts at night are detected just as reliably as during daylight hours.

What property types benefit most from tailgating detection?

Any property with gated access control benefits: residential apartment communities, condos and HOAs, commercial office buildings, parking garages, student housing, and gated retail/warehouse facilities. Properties with high tailgating issues see the most immediate security improvement.

How does tailgating detection reduce crime?

By instantly detecting and alerting on unauthorized vehicle entries, you eliminate the anonymity that enables crime. Criminals can no longer follow residents through gates undetected. The visible LPR cameras also serve as a deterrent—would-be offenders know their plates are being captured.

How Tailgating Detection Works

ParkStash Fixed LPR cameras detect unauthorized vehicles following permitted vehicles through access points and send instant alerts.

Permitted Vehicle Enters

A vehicle with a valid permit approaches the gate. LPR camera reads the plate and confirms permit status. Gate opens for authorized entry.

Second Vehicle Detected

LPR camera detects a second vehicle following behind before the gate closes. License plate is captured and checked against permit database.

Permit Check Fails

Second vehicle does not have a valid permit. System flags this as a tailgating violation with photo evidence of both vehicles.

Instant Alert Sent

Site management, enforcement team, and tow companies receive instant notification with photos, plates, and timestamps for immediate action.

THE SECURITY GAP

Traditional Access Control Has a Fatal Flaw

Fob-based and RF systems let anyone through the gate—they just follow a resident. No verification, no detection, no record.

Fob-Based Systems

Anyone can hold the gate for anyone. Lost or shared fobs give unauthorized access. No way to know who's actually entering.

RF Transmitter Systems

Gate opens, multiple cars enter. No per-vehicle verification. Tailgaters enter undetected and park wherever they want.

Card/Badge Systems

One swipe, unlimited vehicles. Residents let friends, delivery drivers, and strangers through. Complete security bypass.

LPR Tailgating Detection Closes This Gap

ParkStash Fixed LPR cameras verify every single vehicle that enters—not just the one that triggered the gate. Unauthorized tailgaters are instantly detected and reported.

HOW IT WORKS

Detect Tailgaters in 4 Steps

From gate entry to instant alert—every unauthorized vehicle is caught and reported in seconds.

Valid permit holder approaches gate. LPR reads plate, confirms permit, gate opens for authorized entry.

LPR detects second vehicle following through before gate closes. Plate captured and checked against permit database.

No valid permit found for trailing vehicle. System flags tailgating violation with photo evidence of both vehicles.

Site management, enforcement, and tow companies receive instant notification with photos, plates, and timestamps.
