PDK vs. Brivo vs. Verkada
Three good cloud platforms that are genuinely different underneath. Here is how they compare from the installer side, including where each one gets awkward.
We install all three. Nobody is paying us to say nice things about any of them, and we have pulled out all three at one point or another when they were wrong for the building. This is the comparison we give people over the phone, written down.
We should say plainly that PDK is our most common install, so read this knowing that. It is not a sponsorship. It is the platform that has caused us the fewest callbacks across a lot of Orange County buildings, and further down we tell you where it is the wrong pick.
How they compare
| PDK (ProdataKey) | Brivo | Verkada | |
|---|---|---|---|
| Best for | Most commercial buildings; growing door counts | Mixed vendor stacks; heavy integration needs | Buying doors and cameras at the same time |
| Software cost | Quoted per project; ask us for your number | From about $13.50 / door / month | Door licenses, commonly $249 / yr or $599 / 3 yr |
| Credentials | Smartcard, 125 kHz prox, and mobile on one reader | Cards and mobile, Apple and Google Wallet | Cards and mobile, tied to the Verkada app |
| Adding doors later | Add a Red expansion controller; simplest of the three | Straightforward, panel dependent | Straightforward, at Verkada hardware prices |
| Camera story | Bring your own; no preferred brand | Integrates with Eagle Eye, Milestone, others | Native, and the main reason to buy it |
| Watch out for | Shorter integration list; sold through installers only | Feature tiers add up as you climb them | Hardware and licensing both carry a premium |
Brivo and Verkada figures are publicly listed starting points as of 2026 and move with deployment size, term, and tier. All three are sold through integrators, so the number on your quote depends on the project. Hardware and labor are separate and usually larger: budget $3,000 to $4,000 per door installed. See our Orange County cost guide.
PDK (ProdataKey)
PDK is built around a Cloud Node that acts as the gateway to pdk.io and can run a door by itself. For a single-door job that is the whole system. When the building grows, you add a Red expansion controller and the new doors show up in the same dashboard. That sounds like a small thing until you have watched a customer outgrow a panel and get told the fix is a new panel.
The credential handling is the part we appreciate most in retrofits. The readers take 13.56 MHz high-security smartcards, older 125 kHz prox cards, and Bluetooth mobile credentials. Most Orange County buildings we walk into already have prox cards in circulation. Being able to keep those working on day one, then move people to phones at whatever pace they want, turns a disruptive cutover into a quiet one.
It also stays out of your way on cameras. PDK has no camera line to sell you, so nothing about the install argues for replacing surveillance you already own and like.
Where PDK is the wrong pick: if you need a long list of software integrations, tying doors into an HR system, a specific visitor management product, or an unusual building automation stack, Brivo's integration library is deeper and you should look there first. PDK also has no video product of its own, so the one-dashboard pitch is not available.
Brivo
Brivo has been doing cloud access control since before most competitors existed, and it shows in the boring, good ways. The platform is stable, the integration list is long, and it does not assume you buy everything else from them. If you have Eagle Eye cameras, a Milestone recorder, or some odd HR system you want to sync employee records from, Brivo probably already talks to it.
The catch is the tiering. The entry subscription is reasonable, and then visitor management, advanced reporting, and some integrations sit on higher tiers. We have watched a $13.50 per door quote turn into something closer to $25 once the customer added the two features they actually wanted. Ask which tier your must-have features live in before you sign, not after.
When a building's requirements start with a list of other software it has to talk to, Brivo is usually our recommendation over PDK.
Verkada
Verkada sells one dashboard for cameras, doors, alarms, and sensors, and that pitch is honest. When a door forces open at 2 a.m., you see the event and the video of the event in the same window without exporting anything or matching timestamps by hand. For a facilities manager covering several sites, that is worth real money.
It is also the most expensive way to do almost any of this, and the most locked in. Hardware carries a premium, licenses are per door on fixed terms, and the model only works if you commit to Verkada for the cameras too. If you already own cameras you like, most of the advantage evaporates and you are paying the premium for nothing.
Buy Verkada when you are replacing cameras and doors in the same project, you have multiple sites, and one pane of glass genuinely matters to whoever manages the building. Otherwise it is hard to justify.
What actually decides it
After doing this for a while, the platform matters less than three things people rarely ask about when they are comparing feature charts.
- Your door hardware. The electrified locks, strikes, and exit devices cost more than the software and do not care which cloud you picked. A quote that is vague about per-door hardware is the one to worry about.
- Who administers it. The best platform is the one whoever adds and removes employees will actually log into. If that person is an office manager rather than an IT admin, weight the interface heavily.
- Who installs it. Every one of these platforms fails the same way in the field: bad wiring, a controller in a hot closet, no labeling, and nobody documented the schedules. That is an installer problem, not a platform problem.
