The short version

  • Only DemandStar has a free tier, so it costs nothing to try first.
  • Each has a real cost: DemandStar coverage is opt-in by agency, so a supplier paying for a state tier receives only participating agencies and must still monitor other portals for the rest.; 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: DemandStar covers Free for agencies, 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.

DemandStar

  • Coverage is opt-in by agency, so a supplier paying for a state tier receives only participating agencies and must still monitor other portals for the rest.
  • The free supplier tier charges around 5 US dollars per bid document download, which turns an apparently free plan into a metered one as soon as you actually pursue opportunities.
  • State pricing ranges from roughly 100 to 1,499 US dollars with the variation driven by agency density, so suppliers cannot predict cost from geography alone.
  • Because agencies pay nothing, they have little leverage over the roadmap and features are driven by what makes supplier subscriptions sell.
  • The brand is being folded into Euna OpenBid following the Euna Solutions consolidation, so suppliers and agencies should expect the name and portal to change.

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

DemandStar: Is DemandStar free for governments?

Yes, entirely. Agencies post solicitations and access the supplier network at no cost; suppliers fund the platform.

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.

DemandStar: What do suppliers pay?

Free for one agency with roughly 5 USD per document download, about 60 USD a year per county, 100 to 1,499 per state, and 2,699 for national coverage.

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.

DemandStar: Who owns DemandStar?

Euna Solutions, the public sector portfolio formerly known as GTY Technology, which also absorbed Bonfire and Ion Wave.

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.

DemandStar: Does it cover every agency?

No. Only agencies that have opted in, which is the main limitation for suppliers buying wide coverage.

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.
