Why vendor-independent, open-platform security integration protects you from lock-in. ONVIF, OSDP, and how a C-7 integrator specifies for portability.
Three layers. (1) One UL 827–listed central station with a single automation platform (Bold Manitou, DICE, stages) holding a unified contact and dispatch rulebook. (2) Cloud-managed panels (DMP Entré, Bosch RPS-cloud, Honeywell ProSeries) with SCIM provisioning from your IdP so user PINs follow HR offboarding. (3) Site-tiered dispatch profiles — flagship vs. mall vs. standalone — each with its own video-verification trigger map.
A national brand sells, then subcontracts. The labor on your site is rarely the company on your invoice. A California C-7 Low Voltage Systems contractor (CSLB-issued) is the licensed party performing the install; an ACO license (BSIS) authorizes the alarm operation. SafetyCentric holds C-7 #10225534 and ACO #7729. We install non-proprietary hardware (Mercury / HID Aero panels, Axis cameras, DMP intrusion) that you own, on month-to-month service terms.
If they expose ONVIF Profile S (live stream) and Profile T (event/metadata), yes — they bridge to Milestone XProtect, Genetec Security Center, or Avigilon Unity without replacement. Profile G enables on-camera recording, Profile M covers metadata/analytics. Cameras locked to a proprietary cloud (Verkada, Rhombus) cannot be bridged and require swap-out.
UL 827 governs central-station construction and operation (redundant power, dual ISP trunks, hardened envelope, 5-min staff response to signal). UL 1981 governs the automation software. Signals arrive over SIA DC-09 (IP) or Contact ID (cellular), land in the automation platform, get verified per the account's rulebook, then dispatch via the local PD's priority line. UL 681 is the burglar-alarm system standard; UL 2050 applies only to cleared DoD facilities.
Five mandatory specs. (1) Open hardware: Mercury/HID Aero access panels, ONVIF S/T/G cameras, DMP/Bosch/Honeywell intrusion. (2) Open protocols: OSDP v2 Secure Channel readers (Wiegand prohibited), SIA DC-09 monitoring. (3) IdP integration: SAML 2.0 + SCIM 2.0 provisioning from Okta or Entra ID. (4) Licensing: prime contractor holds active CSLB C-7 and BSIS ACO. (5) Commercial terms: month-to-month monitoring, line-item install pricing, customer-owned firmware and credentials at project close.
