Companies that install, service, or monitor alarm systems in California must hold an Alarm Company Operator (ACO) license through BSIS, a distinct license category from the Private Patrol Operator license that covers guard and patrol services. Some larger security companies hold both licenses if they offer combined physical guard and electronic alarm services.
For a Sacramento property considering an integrated security approach, alarm monitoring and guard patrol are often provided under separate contracts even when purchased from the same parent company, and it is worth confirming which license covers which service. A PPO license does not authorize alarm installation work, and vice versa.
Individuals who install or service alarm systems also need their own qualification card issued under this license category, similar to how individual guards need a guard card under a PPO. Verifying both the company license and the technician's card is a reasonable step when contracting alarm work.
This distinction matters most when evaluating bundled proposals that combine patrol, alarm response, and monitoring services, since it clarifies which regulatory framework and BSIS oversight applies to each component of the contract.
