Evidence and investigative networks
Network segmentation between investigative, administrative, and public-facing functions. Evidence storage architecture aligned to retention obligations. Audit logging that survives a Crown disclosure request.

Infrastructure for police services and public safety operations
Investigative networks where chain of custody is enforced in the architecture, not just the policy. Evidence infrastructure that has to survive disclosure. Detention control systems where a network outage is a safety event. Body-worn camera pipelines, ICAT rooms, and the network adjacent to P.25 land mobile radio. Independent advisory.
What is different about public safety infrastructure
The technical layer in a police service is not a generic enterprise network with a few cameras attached. Investigative networks segregate evidence handling from administrative traffic. Body-worn camera footage flows through a pipeline that has to preserve metadata, chain of custody, and integrity for the duration of the case lifecycle. Access control on evidence rooms, armouries, and detention areas is operationally critical, not nice-to-have. ICAT and interview rooms have specific recording, storage, and disclosure requirements. Detention control system networks cannot tolerate a Layer 2 storm during a shift change.
Designing for these environments requires understanding what the operational workflow actually looks like, what the legal disclosure obligations are, and how the network has to behave when a single dropped frame becomes a defence motion at trial.
Where independent advisory adds value
Body-worn camera infrastructure
Docking station networks. Upload bandwidth and storage sizing. Integration between Axon Evidence.com and on-prem investigative systems. Metadata and chain-of-custody handling at the edge of the network.
ICAT and interview room design
Recording infrastructure that is reliable, redundant, and disclosure-ready. Network and storage design for video and audio capture. Operational handoff that the investigative team will actually use.
Detention control system networks
Network design for detention facility control systems where a switch reboot is a safety event. Redundancy, supervisory pathways, and the operational reality of what happens when something fails at 3 a.m.
P.25 land mobile radio adjacency
Network design adjacent to P.25 systems and dispatch infrastructure. Private LTE and 5G considerations for public safety. The IP side of converged radio environments.
Physical security platform advisory
Genetec Security Center, Synergis, Omnicast, AutoVu. C-CURE 9000. Milestone XProtect. Independent platform selection and deployment review without partner-program incentives.

What field experience looks like
I have worked on infrastructure for law enforcement and public safety operations across Canada. The work has covered ICAT integration into existing investigative environments, evidence network segmentation, body-worn camera pipeline design, detention control system network architecture, network design adjacent to P.25 dispatch operations, and physical security platform deployment in environments where the platform vendor does not have direct visibility into how the system actually gets used at the operational level.
The advisory draws on direct field experience, not product documentation.

Bring in independent advisory before the design is committed
The earliest point of engagement produces the largest change in outcome. Pre-RFP requirements development, design review before equipment is ordered, owner's representative oversight during installation, and post-deployment audit are all available as discrete engagements, each scoped and quoted on its own.
