Architecture decision

Open Architecture vs Proprietary Security Systems

Open architecture means the software layer supports hardware from many manufacturers, so you can change cameras without changing platforms and change platforms without changing cameras. Proprietary welds the two together, which puts the leverage with the vendor at every renewal. The real question is not what happens on install day. It is what happens in year seven.

Buyers rarely regret this decision in year one. They regret it in year seven, when a camera line is discontinued, a platform raises its pricing, or an acquisition changes the product roadmap.

Roughly 90 percent of what is available in this market is open architecture, so there is a very good chance an existing installed base can be brought forward rather than thrown away. The platform we deploy works with hundreds of manufacturers.

What the words mean in practice

Open architecture means the video management or access control software is written to talk to many manufacturers' hardware, through standard protocols and through maintained native drivers. You keep two independent decisions: which cameras, and which platform.

Proprietary means those decisions are one decision. The cameras only work with that platform, and often the platform only works with those cameras. That can be a genuinely good experience while the relationship is good. It removes your negotiating position when it is not.

The ONVIF profiles, accurately

ONVIF is an interoperability standard organized into profiles. A device and a platform interoperate to the extent they share a conformant profile, which is why the profile matters more than the word ONVIF on a datasheet.

Profile S is being retired, and here is what that does and does not mean

March 31, 2027 is the last date for new product conformance submissions against Profile S. Be precise about this, because it gets overstated constantly in sales material. It is a date for new product conformance submissions. It is not a date on which existing Profile S cameras stop working.

It matters anyway. Profile S mandates an authentication method that no longer meets current security guidance, which is the reason the profile is being wound down. If you are specifying new equipment today, specify Profile T and treat Profile S conformance as a legacy attribute rather than a target.

Native drivers often beat ONVIF on older cameras

This surprises people. For an older camera, a maintained native manufacturer driver frequently exposes more capability than ONVIF does, because major platforms maintain large device packs reaching back much further than ONVIF conformance goes.

The practical consequence is that a camera which fails an ONVIF check is not automatically unsupported. Before replacing anything, check the platform's device pack for that exact model.

Common questions

What is open architecture in security?

It means the software layer supports hardware from many manufacturers, so cameras and platform are two separate decisions. You can replace one without replacing the other, which is what protects your budget at renewal.

What is ONVIF?

ONVIF is an interoperability standard for network video and access control devices, organized into profiles. What matters on a datasheet is which profile a device conforms to, not the word ONVIF by itself.

Is ONVIF Profile S going away?

March 31, 2027 is the last date for new product conformance submissions to Profile S. Existing cameras do not stop working on that date. The reason for the retirement is that Profile S mandates an authentication method that no longer meets current security guidance.

Will I be locked into one camera brand?

Not on an open platform. About 90 percent of the market is open architecture and the platform we deploy supports hundreds of manufacturers, so you can change camera brands over time without changing your software.
