The short version

  • Only Doppler has a free tier, so it costs nothing to try first.
  • Each has a real cost: Doppler developer tier limited to 3 free users with per-user fees beyond that; Rhombus Systems the per-camera annual licence never ends and a camera without an active licence stops working, so the total cost over a ten-year hardware life is several times the hardware price.
  • They diverge on capability: Doppler covers Secrets management, Rhombus Systems covers On-camera storage.
  • 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.

Doppler

  • Developer tier limited to 3 free users with per-user fees beyond that
  • Team plan pricing ($21/user/mo) adds cost for large teams
  • 90-day activity log retention may be insufficient for long-term audits
  • Enterprise plan requires custom pricing conversation

Rhombus Systems

  • The per-camera annual licence never ends and a camera without an active licence stops working, so the total cost over a ten-year hardware life is several times the hardware price.
  • Cameras must be Rhombus, so there is no reuse of existing IP cameras and migrating away means replacing every device rather than changing software.
  • Cloud archiving is priced separately by retention and stream count, and long retention on multisensor cameras runs into five figures per camera, which can dwarf everything else in the quote.
  • On-camera storage is the default retention, so a camera physically stolen or destroyed takes its unarchived footage with it unless cloud archiving was paid for on that camera.
  • Analytics and integrations are good for mid-market needs but shallower than a dedicated enterprise VMS with a large third-party ecosystem, so specialist requirements like advanced LPR or forensic search hit limits.

Answered from the vendors’ own pages

Doppler: Do AI agents count toward my user limit?

No, AI agents and non-human identities receive free access across all Doppler plans, including Developer, Team, and Enterprise.

Source
Rhombus Systems: Do I need an NVR or a server?

No. Cameras record on board and connect directly to the cloud console, which is the main operational reason organisations pick it.

Doppler: What is the difference between Team and Enterprise plans?

Team plan ($21/user/mo) includes SAML SSO, role-based access controls, and 90-day logs. Enterprise adds custom deployment options, unlimited config syncs, 99.95% SLA, and a dedicated account manager.

Source
Rhombus Systems: What does the licence cost?

Roughly $149 per camera per year for Professional and about $199 for Enterprise, typically sold in one, three, five or ten year terms.

Doppler: Can I rotate secrets automatically?

Yes, both Team and Enterprise plans support automatic secret rotation. Developer tier supports manual rotation only.

Source
Rhombus Systems: Is cloud storage included?

No. On-camera storage is the default. Cloud archiving is a separate charge priced by retention duration and number of streams.

Rhombus Systems: Can I use my existing cameras?

No. The platform works only with Rhombus hardware, which is the trade-off for the zero-server architecture.
