Quick Answer Verkada, Avigilon (Alta and Unity), and Rhombus are all cloud-managed access control platforms — but they split on architecture, integration depth, and local support. ABT installs and supports Verkada and both Avigilon lines locally in Colorado; Rhombus is a capable platform ABT doesn’t currently carry. |

40% of businesses experienced a physical security breach in 2024 — and most traced back to an unlocked door or unmonitored access point. The platform you pick matters less than most buyers assume; the deployment and support behind it matters more. |
On This Page The Real Difference Between These Three Where Rhombus Fits — and the Catch What Local Install & Support Actually Buys You |
The Real Difference Between These Three
Every access control vendor calls itself “cloud-managed” now, so that word alone doesn’t tell you much. The differences that actually matter show up in five places:
| Offline resilience | What happens to your doors when the internet drops — does the controller keep enforcing access rules locally, or does the system fail open or closed until connectivity returns? |
| Integration ecosystem | How open is the API, and does it connect cleanly to HR systems for automated onboarding/offboarding, visitor management, SSO, and existing camera or alarm hardware? |
| Deployment model | Fully cloud-native, on-prem, or hybrid — and whether that choice is fixed or flexible as your organization grows. |
| Hardware lineup | Door controllers, readers, cameras, and sensors — and whether you’re locked into one vendor’s hardware or can mix in existing equipment. |
| Local support | Who actually installs it, and who shows up when a reader fails on a Friday afternoon in Denver, Colorado Springs, or Westminster. |
Side-by-Side Comparison
| Verkada | Avigilon Alta | Avigilon Unity | Rhombus | |
| Architecture | Cloud-native, hybrid edge | Cloud-native, serverless | On-prem or hybrid | Cloud-native, edge processing |
| Best-fit size | 1 door to enterprise, multi-site | Multi-tenant, cloud-first orgs | Large campuses, complex integrations | Small to mid, integration-heavy |
| API / integrations | Documented API, webhook support | Open API via Motorola ecosystem | Deep — built for enterprise IT stacks | 100% open API, 50+ native integrations |
| Compliance | SOC 2 | SOC 2, NDAA-aware sourcing | SOC 2, NDAA, ISO 27001-aligned | SOC 2 Type II, TAA |
| Colorado local support | Yes — ABT Verkada Authorized Partner | Yes — ABT sells & services Avigilon | Yes — ABT sells & services Avigilon | No local ABT support |
When Verkada Fits Best
Verkada is the right call for most Colorado businesses that want one system covering doors, cameras, and environmental sensors without a heavy IT lift. The hybrid edge architecture means each controller keeps enforcing access rules even if the internet or cloud connection drops — a real consideration during a Front Range snowstorm or a fiber cut. It scales cleanly from a single-door office to a multi-site operation managed from one dashboard, which is why it’s ABT’s primary recommendation for businesses with 1 to roughly 200 doors across one or several Colorado locations. Verkada’s own hardware line — cameras, access controllers, readers, and environmental sensors for things like air quality and vape detection — all live in the same console, so there’s no juggling separate logins or separate vendors for cameras versus doors.
Avigilon: Alta vs. Unity
Avigilon, part of Motorola Solutions, isn’t one product — it’s two, and the difference matters for which one actually fits your building.
Avigilon Alta (built from the former Openpath access control platform and Ava Security’s video line) is fully cloud-native and serverless, competing directly with Verkada for businesses that want a modern, remote-manageable system with no on-site infrastructure. It’s part of Motorola’s broader Protect ecosystem, which is expanding toward AI-driven automation across video, access, and sensors together.
Avigilon Unity (built on the legacy Access Control Manager platform) runs on-prem or hybrid, and is the better fit for large campuses, government facilities, or organizations with existing infrastructure investment or compliance requirements that specify on-site data retention. It supports deeper hardware customization and more granular integrations, at the cost of more configuration complexity than a cloud-native platform. ABT deploys both lines depending on the building — Alta for cloud-first buyers who want a Verkada alternative, Unity for large or highly regulated sites that need on-prem control.
Where Rhombus Fits — and the Catch
Rhombus Systems is a legitimate cloud-native competitor, and it’s matured well past its early camera-only days. It now covers cameras, access control, environmental sensors, and alarms under one console, with edge processing that keeps doors functioning during a connectivity drop — architecturally similar to Verkada. Its standout is openness: a fully documented, 900+ endpoint API and 50-plus native integrations spanning Microsoft, Google, Slack, SSO providers, and HR systems for automated credential provisioning when someone’s hired or terminated. Rhombus completed an independent SOC 2 Type II attestation in early 2026 and struck a channel partnership with Honeywell that same spring — both signals of a platform gaining real enterprise traction, reflected in strong independent user reviews on G2.
The catch for a Colorado buyer: ABT is not a Rhombus dealer, and there’s no established local Front Range channel partner offering install and ongoing support the way there is for Verkada and Avigilon. Buying Rhombus today generally means self-installing hardware or working directly with the vendor remotely — workable for a single-location business with in-house technical staff comfortable managing an open API, but a real gap if you want someone local to show up when a reader fails. [VERIFY IF QUOTING SPECIFIC PRICING — third-party reseller figures for Rhombus hardware and licensing change frequently; this post intentionally avoids quoting hard numbers ABT can’t stand behind.]

Integration Ecosystem: Where Each Platform Connects
If your business already runs HR software, an SSO provider, or a visitor management system, how well the access control platform talks to those tools matters as much as the door hardware itself.
| Platform | Integration notes |
| Verkada | Documented API and webhooks for custom workflows; strongest when staying inside Verkada’s own camera, sensor, and access hardware rather than bridging to third-party systems. |
| Avigilon Alta / Unity | Alta connects into Motorola’s broader Protect ecosystem; Unity is built for deep enterprise IT integration — alarm systems, visitor management, life-safety platforms — where a security integrator handles the connections. |
| Rhombus | The most open of the four — a fully documented REST API with 900+ endpoints and 50-plus pre-built integrations, including automated HR-driven onboarding/offboarding. Best fit for a business that wants to build custom workflows in-house. |
What Local Install & Support Actually Buys You
The platform comparison matters, but it’s not the whole decision. Cloud-managed doesn’t mean maintenance-free — someone still has to run cable, mount hardware correctly for Colorado’s temperature swings, configure access groups and schedules to match how your business actually operates, and be reachable when something breaks. ABT’s Verkada and Avigilon deployments include a site assessment before any hardware is ordered, local installation from technicians who service Denver, Colorado Springs, and Westminster, and a direct point of contact afterward — not a support ticket routed through a call center in another time zone. That’s the part a vendor-direct or DIY Rhombus deployment has to solve on its own.
Which Platform Fits Which Kind of Building
| Building type | Likely fit and why |
| Medical practice or clinic | Verkada — HIPAA-relevant audit logging, camera and door integration for exam-room and records access, minimal on-site IT footprint. |
| Construction site / jobsite | Verkada — mobile credentials for rotating subcontractor crews, offline resilience where connectivity is inconsistent. |
| Warehouse or distribution center | Verkada — dock-door scheduling, driver credentialing, camera-linked audit trails for a high-turnover environment. |
| Multi-tenant office building | Avigilon Alta — purpose-built for exactly this use case, cloud-native with tenant-level access management. |
| Large campus or government facility | Avigilon Unity — on-prem control, deep customization, alignment with existing compliance infrastructure. |
How to Decide
| If this is true for your building… | …this is likely your fit |
| Multiple Colorado locations, want one dashboard, minimal IT overhead | Verkada |
| Multi-tenant building, cloud-first, want a Verkada alternative | Avigilon Alta |
| Large campus, existing on-prem infrastructure, complex compliance needs | Avigilon Unity |
| Single site, in-house IT staff comfortable managing an open API, no local support needed | Rhombus — with the local-support tradeoff in mind |
|
Bottom Line All four options can secure a Colorado building well. The deciding factor for most businesses isn’t the software feature list — it’s who’s designing the deployment correctly and supporting it after the sale. That’s why ABT leads with Verkada and both Avigilon lines: they’re the platforms ABT can actually stand behind locally, from Denver to Colorado Springs to Westminster. |
Frequently Asked Questions
|
Is Verkada better than Avigilon for a small Colorado business? For most businesses under roughly 50 doors and one to a few locations, yes — Verkada’s simpler setup and lower IT overhead usually wins. Avigilon Alta is the closer comparison for multi-tenant buildings; Avigilon Unity pulls ahead only for large, complex campuses. |
What’s the difference between Avigilon Alta and Avigilon Unity? Alta is fully cloud-native and serverless, built from the former Openpath platform. Unity runs on-prem or hybrid and is built for large campuses needing deeper customization and on-site data control. |
|
What is Rhombus Systems and how does it compare to Verkada? Rhombus is a cloud-native camera, sensor, and access control platform with a notably open API and strong compliance credentials. Architecturally it’s close to Verkada; the practical difference for Colorado buyers is that ABT and most local dealers don’t currently carry it. |
Does Avigilon require an on-site server? Only if you choose Avigilon Unity. Avigilon Alta is fully cloud-native and serverless, the same as Verkada. |
|
Can I mix access control brands with my existing camera system? Sometimes, through third-party integrations, but you lose the unified single-dashboard experience that’s the main advantage of these platforms. A same-brand deployment is almost always the cleaner path. |
Which access control system works best if my internet goes down? Verkada, Avigilon Alta, and Rhombus all use edge processing that keeps doors enforcing access rules locally during an outage — a real consideration during Colorado’s weather-related disruptions. Avigilon Unity’s resilience depends on its on-prem configuration. |
|
How much does commercial access control cost in Colorado? Pricing depends on door count, camera coverage, and number of sites. ABT provides budgetary pricing after a brief, free site assessment rather than a generic per-door number that won’t reflect your actual building. |
Does my HR system need to connect to my access control platform? It doesn’t have to, but it removes a manual step — automated credential provisioning when someone’s hired and automatic revocation when they leave. Rhombus and Avigilon Unity have the deepest HR integration options; Verkada handles this through its own API. |
