Video and optics
Requirement
Identification-grade image at the required distance under the site's actual lighting and weather, at a bandwidth and retention the network and storage can carry.
Selection basis
Selected against measured sight lines, lux levels and target pixel density — never against a specification sheet alone.
- ONVIF Profile S/G/T
- IEC 62676
- IP66/IK10
Analytics and AI
Requirement
Detection accuracy that holds in the site's conditions, with a false-alarm rate an operator can sustain across a shift.
Selection basis
Evaluated on site footage under worst-case conditions, not on vendor demo material.
- Edge GPU/NPU inference
- Model tuning on site data
PSIM and integration
Requirement
Correlation across security, fire, building and transport systems, with an incident workflow the operator can follow under pressure.
Selection basis
Chosen for the breadth of interfaces we can prove, not the length of the integration list.
- Open API integration
- Documented interface register
Network and transport
Requirement
Deterministic behaviour for video and control traffic, with segmentation between OT, IT and security domains and known failure domains.
Selection basis
Sized from calculated traffic profiles, certified on installation, documented as-built.
- ISO/IEC 11801
- TIA-568
- IEC 61850 where applicable
Power and continuity
Requirement
Declared autonomy and transfer behaviour demonstrated under load, not calculated on paper.
Selection basis
Load-bank tested at commissioning; serviceability and spares availability weighted equally with efficiency.
- IEC 62040 (UPS)
- ISO 8528 (generating sets)
- IEC 60364
Cooling and environment
Requirement
Thermal envelope maintained at design density with headroom for the declared growth step, including liquid-cooling readiness for AI loads.
Selection basis
Modelled for airflow before selection; validated by integrated systems testing.
- ASHRAE TC 9.9 envelopes
- Containment discipline
Monitoring and DCIM
Requirement
An alarm hierarchy an operations team can act on, and capacity data an owner can plan with.
Selection basis
Judged by what the night shift can act on, not by dashboard density.
- SNMP/Modbus/BACnet integration
- Documented alarm hierarchy
Cyber hardening
Requirement
The security and OT estate hardened, segmented, patchable and monitored — an installed camera is a network endpoint before it is a camera.
Selection basis
Patchability and vendor disclosure practice are selection criteria, not afterthoughts.
- IEC 62443 principles
- NAC and segmentation
- Firmware lifecycle
