The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: Camio the 4.99 US dollars per camera per month starting rate is genuinely a starting rate: Flex add-ons run from 1 to 89 dollars per stream per month, so a busy camera with detailed vehicle labelling can cost more than fifteen times a quiet one and a site budget built on the headline number will be badly wrong.; Sigstore the security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.
  • They diverge on capability: Camio covers Natural language video search, Sigstore covers Fulcio.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Camio

  • The 4.99 US dollars per camera per month starting rate is genuinely a starting rate: Flex add-ons run from 1 to 89 dollars per stream per month, so a busy camera with detailed vehicle labelling can cost more than fifteen times a quiet one and a site budget built on the headline number will be badly wrong.
  • Camio is analytics and search, not a full video management system, so most sites still need a recorder or VMS alongside it and end up with two products and two bills.
  • The Camio Box gateway must sit on the same local network as the cameras, which means a device, power and network port at every site, and multi-site estates multiply that install work.
  • It is a small private company against Verkada, Eagle Eye and the analytics bundled free into major VMS platforms, so it is structurally exposed to an incumbent bundling equivalent capability at no extra charge.
  • Analytic accuracy depends heavily on the existing cameras’ placement, resolution and lighting, and cameras installed years ago for recording rather than for computer vision often produce detection rates that disappoint against the demo.

Sigstore

  • The security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.
  • It is a 99.5 percent objective with no service level agreement, which permits several hours of downtime a month and offers no remedy. A pipeline that signs on every build has taken a hard dependency on a free service with no contract behind it.
  • Log scale is a live engineering problem rather than a theoretical one. The active shard holds billions of entries, the log has already been sharded twice, and sharding version 1 requires stopping traffic, which is why a replacement was built.
  • Ten-minute certificates make trust depend on log availability. Verifying an older signature relies on the log entry proving it was made inside that window, so a lost or unreachable entry can render a valid artifact unverifiable.
  • Migration debt is substantial and ongoing. Version 2 of the log is generally available but not the public default, the signing client has an announced breaking release ahead, some official clients lag the new log format, and a post-quantum migration is named as the next break after that.

Answered from the vendors’ own pages

Camio: Do I have to buy Camio cameras?

No. Camio works with ONVIF and RTSP cameras you already have, which is the main reason to choose it over camera-bundled AI platforms.

Sigstore: Is the public instance really free?

Yes, with no contract and no paid tier. That is also the weakness: a 99.5 percent objective with no agreement, no remedy and support through Slack.

Camio: Do I have to buy the Camio Box?

Not necessarily. The gateway software can be downloaded onto hardware you already own; Box and Box Pro units are for sites needing more processing capacity.

Sigstore: Has the public log moved to Rekor v2?

No. Version 2 reached general availability in October 2025 and self-hosters can use it, but the public instance still defaults to version 1 and the project has said it will for the foreseeable future.

Camio: What does it really cost?

Plans start at 4.99 US dollars per camera per month, but Flex add-ons run from 1 to 89 dollars per stream per month, so per-camera cost varies enormously by traffic and labelling detail.

Sigstore: Does Sigstore make my dependencies safe?

No, and this is a category error worth avoiding. It tells you who published something. It has no knowledge of what the artifact contains or whether it is vulnerable.

Camio: Does Camio replace my recorder?

No. It adds search and alerting. Continuous recording and evidence retention usually still need a VMS or recorder.

Sigstore: What are the rate limits?

Not published. Only the 100KB cap per attestation upload is documented, so do not design a high-volume pipeline around assumed throughput.

Sigstore: Should we self-host it?

If a public record of every signature is unacceptable, or if a free service with no agreement cannot sit in your build path, then yes. Otherwise the public instance is what most projects use.
