Where each one falls short

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

Eagle Eye Networks

  • Cost scales with retention as well as resolution, and long retention has been observed to increase the monthly figure by 200 to 400 percent over 7 day storage, so an insurer or regulator raising the retention requirement can multiply the bill without adding cameras.
  • Pricing is not published, so the widely cited 15 to 50 US dollars per camera per month range is a reseller-derived estimate rather than a rate you can hold Eagle Eye to.
  • Every camera needs upstream bandwidth for continuous upload, so sites on poor connections either degrade quality or lose the cloud advantage, and the bridge only buffers for a limited period during an outage.
  • Video lives in Eagle Eye’s data centres, which raises data residency questions for public bodies and for European buyers, and exit means downloading years of footage before a subscription ends.
  • It is a per-camera subscription with no perpetual option, so a large site that would have paid once for an on-premises VMS pays indefinitely, and the crossover point against a Genetec or Milestone deployment usually arrives within a few years.

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
