Which security layer to deploy first in a warehouse — access control, intrusion detection, or video surveillance. C-7 licensed integrator guidance.
All three layers — access control, intrusion detection, and video — because warehouses fail when one layer is missing. Access control alone leaves you blind to after-hours forced entry. Intrusion alone has no audit trail of authorized movement. Video alone records the crime but never prevents it. The right baseline for an IE distribution warehouse is OSDP access on every external door, a UL 681 intrusion panel with dock-door and roof-hatch zones, and identify-grade cameras at every dock + recognize-grade at aisle intersections.
Access control is an "always-on" credential decision — it answers "is this card allowed through this door right now?" Intrusion alarm is an "armed-window" detection system — it answers "did motion or breach happen during a time the building should be empty?" The two systems interlock: arming the intrusion panel locks down the access controllers to admin-only credentials, and a forced-door event on access generates an alarm on intrusion. They are not interchangeable; a warehouse needs both.
No — that is the most expensive way to get the worst results. Cameras should be placed against a stated purpose with a target pixel density: identify-grade (80+ px/ft) at every dock door and high-value cage entry, recognize-grade (50 px/ft) at aisle intersections and staging areas, detect-grade (25 px/ft) for wide-area situational awareness. A 4K dome at 30 feet of throw is wasted if you needed identification at the door. The lens and sensor choice flows backward from the purpose.
The floor is 30 days for most commercial; the practical baseline for warehouses with insurance and OSHA exposure is 60 days; high-value commodities (pharma, jewelry, precious metals) are 90 days minimum. Storage is sized on the camera matrix — count, resolution, frame rate, codec (H.265 mandatory) — not estimated. We size with the manufacturer's calculator and show the math.
On a dedicated security VLAN, not the production network. Access controllers, IP cameras, intrusion panel, and intercom all live on the same isolated VLAN with documented switch uplink sizing (typically 1 Gbps per 40-camera segment). The VLAN routes to the central station IP path and to the head-end VMS / access management server, with no east-west traffic to production. This isolation is required by most cyber insurance carriers and is standard SafetyCentric practice on every commercial install.
Access Control vs Intrusion vs Video — What an Inland Empire Warehouse Actually Needs
How the three commercial security layers work together in a distribution warehouse — area-by-area spec, retention math, and the IE-specific deployment checklist.
Internal shrink traces back to dock access and camera pixel density. After-hours forced entry traces back to an intrusion panel that wasn't zoning the dock doors. Slip-and-fall claims trace back to video retention that ran out before the lawsuit arrived.
