The short version

  • Only Cosign 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.; Cosign keyless signing inherits every weakness of the identity provider behind it. Sigstore’s own threat model states that if an identity provider is compromised, Sigstore will issue certificates to those identities, so a compromised account produces perfectly valid signatures.
  • They diverge on capability: Camio covers Natural language video search, Cosign covers Keyless signing.
  • 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.

Cosign

  • Keyless signing inherits every weakness of the identity provider behind it. Sigstore’s own threat model states that if an identity provider is compromised, Sigstore will issue certificates to those identities, so a compromised account produces perfectly valid signatures.
  • A signature proves who signed, never whether they should have. The documentation is explicit that Sigstore cannot determine authorisation, so every consumer must write and maintain their own identity and issuer policy or verification means nothing.
  • Nothing is enforced without an admission controller. Signing changes what you can prove, not what runs, and the official policy controller has a small maintainer base for a component sitting in a cluster admission path.
  • Upgrades break pipelines. Version 3 changed defaults, version 4 is announced as removing legacy functionality and roughly half the command line flags, and two official client libraries still lacked support for the new log format as of mid 2026.
  • Signatures do not expire. An artifact signed before a maintainer account was compromised and one signed after are indistinguishable unless somebody is actively monitoring the transparency log, and almost nobody is.

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.

Cosign: Does Cosign tell me if an image is vulnerable?

No. It has no vulnerability knowledge whatsoever. It can carry an SBOM as a signed attestation but never reads it. Pair it with a scanner.

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.

Cosign: Is signing alone enough?

No. Verification is a command somebody runs. Without an admission controller enforcing it, an unsigned image still runs.

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.

Cosign: What does a bare cosign verify actually prove?

Very little. Without a pinned certificate identity and OIDC issuer, it accepts a valid signature from any identity at all.

Camio: Does Camio replace my recorder?

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

Cosign: What is the risk of keyless signing?

Your OIDC provider becomes the root of trust. Compromise of that account yields genuine, verifiable signatures, so account security is the control that matters.

Cosign: Should we expect breaking changes?

Yes. Version 4 is announced to remove roughly half the flags, and a post-quantum migration is named as a further breaking change after that.
