Why this module exists. CCTV, visitor management systems, and integrated incident-response are the detective layers of physical security. Done well they catch what preventive controls miss; done badly they generate noise that obscures real signal. This module covers the operational design for Indian enterprise environments.

Why this module exists. Most Indian enterprises have CCTV; few have CCTV that catches anything before-the-fact. The difference is in coverage planning, retention discipline, and integration with the SOC. This module covers what works.

CCTV coverage — where to place cameras

The principle: cover every transition between zones and every high-value asset. Practitioner placement list:

  • Every external entry / exit, with sufficient resolution to identify faces at distance.
  • Reception area — entry + exit + employee transit through.
  • Every transition between security zones — corridor cameras catching the door.
  • Data centre — cage entry, hot aisle, cold aisle, equipment racks.
  • Critical IT equipment — KVM stations, console access points.
  • Loading docks and any goods-receiving area.
  • Parking — at least entry / exit and major rows.

The trap: covering generic floor space at high density (10 cameras per floor) while leaving transitions uncovered. Plan from threat model: who comes in, where do they go, where would they touch your data — that is where the cameras go.
