Official documentation

The door controller family covers the access control layer of a Verkada deployment. The AC12 is a single-door controller, available in a standard version and a government variant built to FIPS 140 and TAA requirements. The AC41 and AC42 are both four-door controllers, while the AC43 is a four-door controller offered with regional configurations for Australia, Europe, and Japan, plus a government FIPS 140 and TAA-compliant option.

For most commercial sites, the AC12 suits small offices and single-entry deployments, while the AC41, AC42, and AC43 step in when multiple doors share a panel. The regional AC43 variants let multinational organisations select the correct hardware for each country without mixing power supplies or compliance profiles. The government SKUs address federal, state, and regulated environments that require FIPS-validated cryptography and TAA-compliant sourcing.

The family fits anything from a single-suite office to a multi-building campus, with the controller choice driven by door count, geography, and any compliance obligations. Request a quote with your door count, country, and any government or compliance requirements.

How HTS deploys it

Controller choice is arithmetic before it is preference: door count per panel, distances between doors, and where conduit can actually run. The AC12 serves single openings; the AC41, AC42, and AC43 four-door panels serve clusters. HTS groups doors onto shared panels where the wiring supports it and leaves isolated openings on their own controller — pulling four doors' cable to a panel that does not fit them is the most common way an access budget doubles.

Government and regional variants are confirmed at design time: FIPS 140 / TAA requirements select the -G SKUs, and the AC43's regional power configurations serve multi-country estates. Panels ship pre-configured to the door schedule — lock outputs, reader addresses, request-to-exit, door position — and hand-off includes every door badging in and every event landing in Command.

What it costs to run over three years

The licence is per door, not per controller — a four-door panel needs four door licences. Figures are HTS catalog prices from the 2026-09-21 snapshot.

  • Controller hardware, one-time: AC12 $854.05, AC42 $1,899.05, AC43 regional $1,899.05; government and other variants list on the store.
  • Door licence, per door: $236.55 one year / $569.05 three years / $949.05 five years.
  • Worked example: one AC42 with all four doors licensed for three years runs $1,899.05 + 4 × $569.05 = $4,175.25 — about $1,044 per door for three years before readers and locks.
  • Readers, credentials, and lock hardware price per door on top; the door licence is the line that renews.
  • Growth is the cheap direction: the fourth door on a four-door panel is a licence, while a fifth door is a licence plus a new panel.

What else this needs

  • One door licence per opening (LIC-AC-*), renewed at term.
  • Ethernet to each controller and power per the install document; reader, lock, request-to-exit, and door-position wiring per door.
  • A reader per door (see the card-reader family) and credentials per person.
  • Lock hardware — strike or maglock, chosen deliberately for the opening's fire and egress obligations.
  • For regulated sites, the FIPS 140 / TAA government SKUs identified before the quote.
