Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GNAT Pro

  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs

Motorola Vigilant

  • State law can decide eligibility outright: California's SB 34 imposes operator duties and restricts sharing ALPR data with out-of-state and federal agencies, and agencies have been audited and found non-compliant.
  • Local surveillance technology ordinances increasingly require a published usage policy, retention limits and a public council hearing before purchase, which can add many months or block the procurement entirely.
  • Motorola has faced litigation over its dual role as ALPR operator and end user, so the legal exposure of the data-sharing model is unresolved and sits partly with the purchasing agency.
  • The value comes from the shared LEARN database, which means the capability an agency actually buys depends on what other agencies contribute, and that can shrink if peers withdraw for legal or political reasons.
  • Nothing is published on price, and camera hardware, database subscription and analytics are separate line items, so the multi-year total is far higher than the initial camera quote suggests.
