Can I use any camera with an open-platform VMS?

Most commercial cameras with ONVIF Profile S support connect to Milestone, Genetec, or ExacqVision at a basic level. For full feature support (motion events, audio, PTZ control, edge analytics metadata), the camera needs a dedicated device driver in the VMS. Milestone has drivers for over 10,000 camera models; Genetec's library is similarly broad. Verify your model is on the driver support list before specifying. Most cameras from Axis, Hanwha, Bosch, Sony, Pelco, and i-PRO are.

Is Genetec Security Center truly open, or does it prefer Genetec hardware?

Genuinely open. Genetec Security Center connects to cameras from Axis, Hanwha, Bosch, Avigilon, Sony, i-PRO, and hundreds of others via ONVIF and dedicated drivers. Genetec does not manufacture cameras; it is purely a software company, and Synergis (the access module) integrates with HID, Lenel, Axis, and other readers and controllers. The integration library is one of the broadest in the industry. That said, it is an enterprise product with a complexity curve, not the right choice for a 20-camera single-site without IT resources.

Do proprietary VMS platforms work with NDAA-compliant cameras from other manufacturers?

Generally no. Verkada only works with Verkada cameras, Avigilon Unity has limited ONVIF support but is designed for Avigilon hardware, and Rhombus is closed to Rhombus cameras. This is by design: the integration quality proprietary vendors promise depends on owning the full camera-to-cloud stack. Existing NDAA-compliant cameras from Axis or Hanwha cannot migrate to a proprietary VMS. When preserving an existing camera fleet matters, open-platform is the right choice.

Can I run third-party AI analytics on a proprietary VMS?

Usually not. Proprietary platforms (Verkada, Rhombus, Avigilon Alta) run only their own native AI. Camera-agnostic overlays like Dragonfruit AI and Intenseye require an open-platform VMS that accepts third-party plugins via SDK or video stream. Some proprietary platforms offer a limited app marketplace, but the selection is narrow next to Milestone and Genetec. If camera-agnostic AI analytics is a requirement, open-platform is the path.

What is the difference between Milestone XProtect and Genetec Security Center?

Both are open-platform enterprise VMS leaders. Milestone XProtect is the benchmark for camera compatibility: broadest driver library, longest-running open SDK, largest third-party developer ecosystem. Genetec Security Center is a unified physical security platform: video, access control (Synergis), LPR (AutoVu), and intercoms in one database. Want unified video-plus-access with the deepest integrations? Genetec. Want the widest camera compatibility and largest analytics plugin library? Milestone. Tec-Tel installs both.

NDAA-compliant
Platform-agnostic
1,000+ deployments over 15 years

Go with a proprietary VMS when you want fast deployment, thin IT, and a single vendor accountable for camera plus software plus support. Go with an open-platform VMS when you need camera-vendor flexibility, long retention, deep third-party integrations (access control, PSIM, elevator dispatch), or NDAA-compliant mix-and-match across Axis, Hanwha, Bosch, and others. Most enterprise deployments with 200+ cameras or multi-vendor requirements land on open platform. Smaller single-site deployments without integration complexity often benefit from the proprietary simplicity.

§01 At a glance

Where the choice gets made.

Find the criterion that matters most for your sites and integration requirements, then read the row. Proprietary examples: Verkada, Avigilon Alta, Rhombus, Avigilon Unity (on-prem). Open-platform examples: Milestone XProtect, Genetec Security Center, ExacqVision, Hanwha Wisenet WAVE, Axis Camera Station.

Criterion	Proprietary VMS	Open-platform VMS
Camera compatibility	Closed ecosystem. Cameras must come from the same vendor (Verkada for Verkada VMS, Avigilon for Avigilon Unity). Third-party cameras are unsupported or limited to a subset via ONVIF with reduced features.	Camera-agnostic. Milestone XProtect, Genetec Security Center, and ExacqVision support thousands of models from Axis, Hanwha, Bosch, Pelco, i-PRO, Sony, and others via ONVIF and dedicated drivers. Mix manufacturers on one system.
IT requirements	Minimal. Proprietary cloud systems (Verkada, Rhombus, Avigilon Alta) need no on-prem server. Cameras phone home outbound. A lean IT team can manage a 100-camera site from a dashboard tab.	Server-based (on-prem open platforms): Windows Server, SQL database, storage arrays, annual patching, VMS upgrade cycles. Assumes internal IT or a managed-service contract. Cloud-hybrid options (Milestone Care, Genetec cloud) reduce but do not eliminate the on-prem footprint.
Upfront vs recurring cost	Lower Day 1 capex for cloud proprietary systems. The recurring per-camera annual license is the dominant cost over 5 years, and the per-camera hardware can run higher than equivalent ONVIF cameras from commodity manufacturers.	Higher Day 1 capex: server, perpetual software license, and implementation. Lower ongoing per-camera cost after year one; annual maintenance is typically 15-20% of the license. Hardware flexibility lets you competitively bid cameras across vendors.
Third-party integrations	Strong within the vendor ecosystem (Verkada access and intercom; Avigilon Alta access). External REST API integrations exist but are thinner than open-platform. PSIM, deep ERP, and legacy building-system integrations are limited.	Integration breadth is the open-platform advantage. Milestone and Genetec run thousands of integrations: access control (Lenel, C-CURE, Brivo, Kisi), intercoms, alarm panels, PSIM, building management, visitor management, and AI overlays (Intenseye, Dragonfruit). The SDK is public; third parties build against it.
AI analytics	Native AI in the camera and dashboard. Verkada ships people, vehicle, and attribute detection; Avigilon ships Appearance Search. Analytics update via the cloud with no user action. You take what the vendor ships.	Choose your analytics layer. Milestone and Genetec support native AI (Milestone AI Smart Search, Genetec AutoVu LPR) plus any third-party overlay (Intenseye for safety, Dragonfruit for video search), adding analytics to any existing fleet. More choice, more integration effort.
Vendor lock-in	High. Migrating away means replacing cameras and software simultaneously, effectively a full forklift. Exit cost is the primary strategic risk of proprietary systems.	Lower. An open-platform VMS can be replaced while keeping the camera fleet. Switch from Milestone to Genetec and your Axis and Hanwha cameras transfer with a configuration migration. Cameras are the long-lived asset; VMS software is replaceable.
Retention and storage	Cloud proprietary: retention is a paid tier. Standard licenses commonly include 30-90 days; longer windows are priced per camera per month, and 180-365 days at scale gets expensive. On-prem proprietary (Avigilon Unity): storage is local, so retention is your hardware.	On-prem open platform: retention is bounded by your storage budget, not a software tier. A 200-camera site at 30fps, 4MP can be sized for 90-day or 365-day retention by adding drives. Per-unit storage cost at high retention is lower on-prem than cloud.
Upgrade cadence	Vendor-managed. Firmware and features push automatically on cloud systems, on the vendor schedule. New features arrive without IT effort; breaking changes arrive on that schedule too.	IT-controlled. Major versions run on your schedule, tested in staging before production. Enterprise customers often lag one major version to avoid regression. The trade is deliberate stability and regression control vs continuous improvement.

§02 Where Proprietary VMS wins

Choose a proprietary VMS when these matter most.

Single-vendor accountability

One call for camera, VMS, and support. When a Verkada or Avigilon Alta camera goes offline, the conversation is with one vendor who owns the whole stack. On open platforms, a camera-VMS compatibility issue turns into a three-party conversation between the camera manufacturer, the VMS vendor, and the integrator.

Fast deployment with lean IT

Claim a camera in the dashboard and recording starts. No server build, no storage sizing, no VMS install, and no redundant NVR or DR site for the video head end. A 100-camera multi-site deployment with thin IT staff deploys faster on Verkada or Rhombus than on Milestone or Genetec at equivalent IT staffing.

Vendor-managed AI roadmap

Analytics update automatically via the cloud. Verkada, Avigilon Alta, and Rhombus push new AI features (object detection, license plate, occupancy analytics) without requiring the customer to upgrade software or change cameras. For organizations that want AI without managing the analytics stack, proprietary delivers it.

Multi-site single pane and predictable budgeting

Proprietary cloud platforms are built for multi-site from day one. A 50-location retail chain gets a single pane with role-based access, cross-site search, and centralized alerts without the server complexity a 50-site on-prem deployment carries. The per-camera annual subscription is a clean opex line: no surprise server refresh, no emergency storage expansion, no upgrade project budget.

§02 Where Open-platform VMS wins

Choose an open-platform VMS when these matter most.

Camera-vendor flexibility

Milestone, Genetec, and ExacqVision run thousands of camera models. You can mix Axis, Hanwha, Bosch, and i-PRO on the same system and use competitively bid hardware at each position. Proprietary VMS requires proprietary cameras; every dollar spent on cameras is locked into that vendor ecosystem.

Deep third-party integrations and AI overlays

Access control (Lenel, C-CURE, Genetec Synergis, Brivo, Kisi), PSIM, building management, elevator dispatch, visitor management, alarm panels, and LPR all integrate against public Milestone and Genetec SDKs. Camera-agnostic AI overlays like Dragonfruit AI and Intenseye plug in as third-party analytics channels to add object search, safety analytics, and business intelligence to an existing mixed fleet. Proprietary platforms connect via REST API but rarely match the pre-built depth and typically do not accept third-party AI overlays.

Large camera counts and long retention

Stadiums, transit hubs, large manufacturing campuses, and airports with 500+ cameras at one address break per-camera SaaS economics. An on-prem Milestone or Genetec server amortizes across those cameras, so per-camera lifetime cost is lower than cloud proprietary at that count. Retention follows: transit agencies, gaming facilities, and corporate security commonly hold footage 180 to 365 days, bounded by drives you buy once rather than a recurring per-camera cloud fee.

Regulated environments and data sovereignty

Defense contractors, regulated healthcare, and government facilities where footage must not leave the network. On-prem open-platform VMS keeps footage in your server room. Cloud proprietary systems send footage to the vendor cloud, which may not satisfy data residency requirements.

§03 How each architecture works

Proprietary and open-platform VMS, defined.

A proprietary VMS is a vertically integrated stack: cameras, recording software, mobile app, and analytics all from one vendor. Verkada cameras run on the Verkada VMS; Avigilon cameras run on Avigilon Unity or Alta; Rhombus cameras run on Rhombus. The advantage is tight integration, a single support contact, and continuous feature updates across the whole fleet. The trade is lock-in: replacing the VMS means replacing every camera.

An open-platform VMS is software on standard server hardware that speaks ONVIF plus vendor-specific drivers to cameras from any manufacturer. Milestone XProtect, Genetec Security Center, ExacqVision (Johnson Controls), Hanwha Wisenet WAVE, and Axis Camera Station are the leaders. Each has a published SDK; third parties build integrations, analytics plugins, and custom modules against it. You can run Axis at the parking garage, Hanwha in the warehouse, and Bosch at perimeter on the same Milestone installation. The VMS is the integration layer, not the hardware.

→ ONVIF Profile S, G, and T let open-platform VMS connect to cameras from different manufacturers. Most commercial cameras ship ONVIF support, but feature completeness varies. Vendor-specific drivers in Milestone and Genetec unlock full feature sets (event types, metadata, PTZ control) beyond generic ONVIF.
→ Hybrid proprietary systems exist. Avigilon Unity (on-prem) supports limited third-party cameras via ONVIF; Verkada does not; Avigilon Alta (cloud) is closed to Avigilon hardware. Verify any "open" claim from a primarily proprietary vendor before committing.
→ Cloud-hybrid open-platform: Milestone Care and the Genetec cloud bridge connect on-prem open-platform VMS to cloud storage and remote management. A middle path: open-platform flexibility on-prem with cloud remote access, reducing but not eliminating on-prem server complexity.

§04 Cost and how to choose

When proprietary wins, when open platform wins, and the 5-year TCO behind it.

Two variables dominate 5-year TCO: camera count and IT model. For a 50-camera single-site deployment with no IT staff, cloud proprietary (Verkada, Rhombus) is often cheaper total once you include the avoided server, storage, and IT labor. For a 300-camera multi-site deployment with staffed IT, open-platform on-prem frequently wins: the server amortizes across 300 cameras, per-camera software cost is lower, and the IT labor is already allocated. Camera hardware is the less-discussed variable. Verkada and Avigilon cameras carry a premium over equivalent Axis, Hanwha, or i-PRO; on open platform you bid competitively at every position, and over a 5-year refresh that delta compounds.

Proprietary wins when deployment speed, thin IT, and single-vendor accountability outweigh flexibility. A retailer rolling out 20 cameras per store across 50 new locations in 6 months does not want to manage Milestone server infrastructure; a K-12 district with no security IT staff wants Verkada or Rhombus, where a facilities manager claims a camera from a browser. Open platform wins when integration depth, camera flexibility, or scale economics are primary. A hospital with 400 cameras tying video into Lenel access, visitor management, and a PSIM layer cannot do that on Verkada; an airport with 600 cameras and a 365-day retention requirement cannot afford the cloud per-camera fee at that window. Tec-Tel installs both and designs from the requirements up, not from a vendor relationship.

→ Open-platform on-prem cost drivers: server and OS, VMS perpetual license plus annual maintenance (typically 15-20% of license), storage and refresh, IT labor (0.1-0.25 FTE for a mid-sized deployment), and competitively bid cameras.
→ Exit cost is a hidden TCO line for proprietary: migrating off after 5 years replaces cameras and software simultaneously. Budget 70-90% of the original install cost. Open-platform exit is a software swap; cameras stay. Multi-year proprietary contracts discount the rate but lock in that exit conversation at year 5.
→ Signal for proprietary: under 200 cameras, no or thin IT, multi-site without per-site servers, strong single-vendor preference, opex budget shape.
→ Signal for open platform: 200+ cameras at one site, camera-vendor mix, deep access control or PSIM integration, regulated data sovereignty, long retention (180+ days), camera-agnostic AI overlay requirement. For hybrid, run proprietary cloud at small branches and open-platform on-prem at the headquarters or regulated campus; Genetec Security Center can ingest cloud feeds as a unifying layer. Always verify the ONVIF device driver version before pairing an open-platform VMS with a specific camera.
