Question 1

What is LPR parking technology and how does it work?

Accepted Answer

LPR uses high-resolution cameras with IR illumination and on-camera or edge-server OCR to read every license plate at entry/exit. The plate becomes the customer identifier — replacing tickets, RFID, and physical credentials. Authorized plates pass through gateless lanes; unauthorized plates trigger digital citations or invoices. Production systems achieve 97–99.5% accuracy in 200–600ms.

Question 2

How accurate are LPR parking cameras?

Accepted Answer

Production-grade systems hit 97–99.5% read accuracy. Three variables drive that: pixel density across the plate (~110 pixels for >98%), capture angle (must stay below 30°), and illumination (dedicated IR outperforms ambient by 18–24%). The most common cause of poor LPR accuracy is camera placement that violates these geometry rules — not hardware quality.

Question 3

How much does an LPR parking system cost?

Accepted Answer

A complete LPR system for a single entry/exit lane costs $14,000–$24,000 in 2026: cameras ($7K–$12K), edge controller and OCR licensing ($2.5K–$4.5K), conduit and cabling ($1.5K–$3.5K), enclosures and mounts ($800–$1,800), commissioning ($1.5K–$2.5K). SaaS recurring costs run $80–$220/lane/month.

Question 4

Can LPR parking eliminate gates and tickets entirely?

Accepted Answer

Yes — gateless LPR has been the dominant new-installation pattern since 2021. Benefits: no ticket dispensers, no gate arm strikes, no exit kiosk lines, lower per-lane infrastructure cost, 2.5–3.5x the throughput of gated lanes. The trade-off is enforcement: gateless systems use payment-after-the-fact mechanisms instead of physical exclusion.

Question 5

How does LPR enforcement work for parking?

Accepted Answer

When the camera reads a plate, the system checks active permits, valid pay-by-plate sessions, and authorized customer lists. No-match plates trigger SMS/email pay invitations, digital citations, staff intercept, or boot/tow dispatch. State DMV partnerships allow registered-owner lookup for invoice delivery. Compliance for properly tuned LPR enforcement consistently exceeds 95%.
