The verdict in 30 seconds

Rhombus publishes its catalogue model by model: camera MSRPs from $399 to $3,299, per-camera licences from $149 for Professional up to $649 for Enterprise, terms of 1, 3, 5 and 10 years and days of storage stated per model, all on a public page a procurement team can model against before it books a call. The catalog behind it is broad, with cameras, access control, sensors and monitored alarms on one console, and the compliance posture is stated up front as SOC 2, NDAA, GDPR and TAA. It scores lower where the hardware is already on the wall, because existing cameras arrive through a Relay Core appliance or a Relay Lite stream rather than natively, and lower again on what the AI is stated to detect, which Rhombus does not name. Choose Rhombus when you are buying the system and the cameras in the same project. Look elsewhere when the cameras are already up and have to do the AI work themselves.

How this was scored

Five criteria, each scored from Rhombus's own current documentation as of August 14, 2026. Spot AI competes with Rhombus, so no score here rests on an anonymous source, an aggregated user rating or a private benchmark: each one sits next to the documented fact behind it. Anything Rhombus does not document is recorded as not publicly specified rather than assumed. Where a fact was not on the product, pricing or Relay pages, this review says so rather than filling the gap from a reseller listing. This is not a paid placement, and Rhombus had no input into it.

What Rhombus prices in public, and what it leaves unnamed

The commercial side of this platform is documented model by model. The detection side is the part that is not.

What Rhombus is, and who it is built for

Rhombus sells a cloud-managed video security system built around its own hardware. The catalog runs from dome, fisheye, bullet and multisensor cameras through door controllers, readers and intercoms to audio, environmental, motion, entry and multipurpose panic sensors, with alarm monitoring on top in the form of TMA 5-diamond certified live agent verification and dispatch. Rhombus describes the architecture as a cloud-edge system that lets a site scale infinitely, operate offline and minimize latency, which is the design answer to a console in the cloud and video that still has to survive a dropped uplink.

The pricing page is the part worth reading first. Rhombus lists MSRPs per model, from the R120 Mini Dome at $399 through the R200 at $599, the R410 Dome and R360S Fisheye at $1,499 each and the R600 Multisensor at $3,299, with the N100 Relay Core at $2,999 and 10-year warranties stated alongside. Licences are published the same way: a Professional tier from $149, which Rhombus states excludes AI features and cloud archiving, and an Enterprise tier up to $649 which adds them, on terms of 1, 3, 5 or 10 years, with days of storage listed per model on default settings.

Openness is stated rather than implied. Rhombus publishes a 100% open API and more than 50 integrations, and existing cameras reach the console through two named products: Relay Core, the N100 appliance, and Relay Lite, which Rhombus offers as the option with no extra hardware. Its own words for the pair are that they let you connect existing ONVIF and RTSP cameras into the Rhombus console without ripping them off the wall.

  • One console over Rhombus cameras, access control, five sensor types and monitored alarms with live agent verification.
  • A public price list: camera MSRPs from $399 to $3,299, per-camera licences from $149 to $649 and terms of 1, 3, 5 and 10 years.
  • Days of storage published per camera model on default settings, on a cloud-edge architecture stated to operate offline.
  • Existing ONVIF and RTSP cameras through Relay Core, the N100 appliance at $2,999, or through Relay Lite with no appliance.
  • A 100% open API, more than 50 integrations and a compliance posture stated as SOC 2, NDAA, GDPR and TAA.
Key takeaway

Rhombus is strongest as one specified system bought in a single project, and thinnest where the cameras are already mounted and the buyer wants to know exactly what the AI will detect on them.

Rhombus pros and cons

Both columns are documented. Nothing here comes from an anonymous review.

What Rhombus does well
The catalogue is published model by model. Camera MSRPs run from the R120 Mini Dome at $399 to the R600 Multisensor at $3,299, per-camera licences from $149 for Professional up to $649 for Enterprise, and contract terms of 1, 3, 5 and 10 years sit next to them. A finance team can model a 40-camera site to the dollar before anybody takes a sales call.
The catalog is genuinely broad for one console. Dome, fisheye, bullet and multisensor cameras, door controllers, readers and intercoms, plus audio, environmental, motion, entry and multipurpose panic sensors, and alarm monitoring described as TMA 5-diamond certified live agent verification and dispatch. A team that wants one vendor across video, doors and alarms is buying one relationship rather than integrating three.
Storage is quantified rather than described. The pricing page states days of storage per camera model on default settings, so retention is a spec a buyer can check against an evidence policy rather than a conversation to have later. Alongside 10-year warranties on the cameras, that is an unusually concrete hardware commitment.
The compliance posture is stated up front: SOC 2, NDAA, GDPR and TAA, published on the product pages rather than produced on request halfway through a security review. Several larger vendors in this category say nothing on their public pages, so this is a real point in Rhombus' favor and it shortens the part of an evaluation that usually drags.
Existing cameras have a documented route with two shapes to it. Rhombus states that Relay Core and Relay Lite let you connect existing ONVIF and RTSP cameras into the Rhombus console without ripping them off the wall, and it lists the appliance at $2,999 for the N100. With both the mechanism and the appliance figure stated, a migration can be scoped before it is quoted.
Openness is published in numbers, not adjectives: a 100% open API and more than 50 integrations across access control, identity, alarm and communication systems, with documentation that is not behind a partner agreement. For a team that already runs its own tooling, that is the difference between a platform and a silo.
What to check before you buy
What the AI detects is not publicly specified. Actionable AI insights and AI-powered search are the whole public surface, with no named detection list, no agent count and no custom-detection path on the pages this review read. That is an absence of published detail rather than evidence of a weak model, and the buyer action is to ask for the detection list in writing before the shortlist closes.
AI features and cloud archiving sit in the Enterprise licence, which Rhombus states the Professional tier at $149 excludes. Read the licence tier against the sites that actually need the analytics, because a fleet priced entirely at Professional is a fleet priced without them.
Which AI features run on a Relay stream rather than on a Rhombus camera is not publicly specified. On a mixed estate that is the question that decides whether the older half of the fleet is a first-class citizen or a viewing tile, and the pages this review read do not answer it.
Existing cameras arrive through a purchase and a per-appliance limit. The N100 Relay Core is listed at $2,999 and Rhombus support documentation states it connects RTSP streaming cameras, with ONVIF used where the camera supports it. Relay Lite avoids the appliance but ties a third-party stream to a Rhombus camera, so a site with no Rhombus hardware yet is buying hardware to reuse hardware.
Firmware on the older cameras stays your job. Rhombus states that users will need to manage updates to their non-Rhombus cameras, which on a fleet nobody has touched in five years is unplanned work rather than a line item.
Automated deterrence behavior is not publicly specified. Audio sensors are sold as a product, and what the platform does with a speaker at 03:00 with nobody watching does not appear on the pages this review read. Ask for the sequence, not the hardware list.

Who should choose Rhombus, and who should look elsewhere

The honest split, stated the way a shortlist call would state it.

Choose Rhombus
A system you are specifying and buying together

If the cameras, the doors and the sensors are all being bought in the same project, and you want one vendor, one console and monitored alarms behind it, Rhombus is a strong answer and an unusually easy one to budget. The public price list, the 10-year warranties and the per-model storage days make it one of the few platforms here you can cost to the dollar before the first call.

Look elsewhere
An installed fleet that has to run the AI itself

If the cameras are already up, come from several manufacturers and the point of the project is AI on those feeds, the Relay path adds an appliance or a tie to a Rhombus camera, and what the AI detects on a third-party stream is not publicly specified. That is the case a camera-agnostic platform is built for, and it is worth pricing both ways.

The Spot AI alternative
AI coworkers on the cameras you own

Spot AI connects to any ONVIF or RTSP IP camera and brings legacy analog in through the Intelligent Video Recorder, runs AI Security Guard across the whole fleet and deters with talk down, strobes and horns through standard speakers. Full-resolution video stays in the building, and only event metadata goes to the cloud.

If you are comparing the two directly

The distance between these two is a difference in what you are buying rather than a feature either side is missing. Rhombus sells a specified system, priced in public, with the AI stated as a capability. Spot AI sells the software layer for cameras somebody already installed, with the detections named and the full-resolution video kept in the building. Both answers are defensible, and which one is right depends almost entirely on whether the hardware decision is still open.

The cheapest way to settle it is to price the same site both ways and then run the one week that matters. Ask Rhombus for the licence tier that carries the AI features, ask both vendors what happens on site at 03:00 with nobody watching, and pilot on the site with the oldest cameras, because that is where a migration story stops being a diagram.

Key takeaway

Quote the identical site list both ways, and put the Relay appliances and the licence tier in the Rhombus column. A per-camera comparison that leaves out the N100 at $2,999 is not the bill either side will send.

Frequently asked questions

Is Rhombus a good video security system in 2026?

Yes, for the right profile. It scores 3.2 out of 5 here, carried by a catalogue published model by model, a broad product line on one console and a compliance posture stated as SOC 2, NDAA, GDPR and TAA. It fits a team specifying cameras, doors and sensors together in one project. Buyers keeping a large installed fleet should read the Relay pages and ask what the AI detects before anything else.

What does Rhombus cost?

Rhombus lists camera MSRPs from the R120 Mini Dome at $399 to the R600 Multisensor at $3,299, the N100 Relay Core at $2,999, per-camera licences from $149 for Professional up to $649 for Enterprise, contract terms of 1, 3, 5 and 10 years, days of storage per model on default settings and 10-year warranties. Volume and negotiated terms are agreed with Rhombus directly.

Does Rhombus work with existing or third-party cameras?

Yes, through two named products. Rhombus states that Relay Core and Relay Lite let you connect existing ONVIF and RTSP cameras into the Rhombus console without ripping them off the wall. Relay Core is the N100 appliance, listed at $2,999. Relay Lite is the option with no extra hardware. Two conditions are published as well: the camera has to speak RTSP, with ONVIF used where supported, and updates to non-Rhombus cameras stay with you.

What AI does Rhombus offer?

Rhombus publishes actionable AI insights and AI-powered search and review, and it places AI features and cloud archiving in the Enterprise licence rather than the Professional one. What is not publicly specified is the detection list itself, or which AI features run on a camera brought in through Relay. Both belong on the evaluation checklist rather than in an assumption.

What is the best Rhombus alternative in 2026?

It depends on which constraint is real for you. If the cameras are already installed, or full-resolution video has to stay in the building, a camera-agnostic platform such as Spot AI fits, because 15+ pre-trained Video AI Agents run across the fleet already up and the video stays on the Intelligent Video Recorder on site. If the hardware decision is still open and the budget has to be modeled early, Rhombus is hard to fault. The alternatives roundup compares the field side by side.
