Where each one falls short

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

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.

Tenable Nessus

  • Nessus Professional is $4,790 for one year, sold as an annual licence rather than a per scan or usage based fee
  • Support beyond the base entitlement costs an extra $400 per year for Advanced Support with 24x365 phone and chat access
  • The on demand training course is a separate $275 purchase for a single person for one year
  • Multi year discounts require paying for two or three years up front
