Write down the event you need to review
Before placing cameras, list a few realistic review scenarios: an unexplained movement near a loading bay, a vehicle at the gate, an incident in an aisle, or activity outside working hours. For each scenario, identify what a reviewer would need to see and who would be allowed to inspect it. This creates a useful brief without promising that one view can answer every question.
Walk the site in its working condition
A clear floor plan is useful, but it does not show every obstruction. Review racks when stocked, large vehicles in their normal positions and temporary staging areas. Note lighting changes and the hours when the site is busiest. Ask how the layout changes through the year. Treat the camera arrangement as a design that may need review as the warehouse changes.
Separate overview from detailed evidence
An overview helps an operator understand a scene. A particular gate or handover point may require a more detailed view. Mark both requirements on the plan and discuss camera position, lens and the conditions in which the view must be usable. Do not use camera count as the acceptance criterion by itself.
Plan recording and retrieval together
Agree retention, recording hours and authorised access before choosing storage. Then include a sample playback and export exercise in the handover plan. Record who can retrieve an incident, how time is kept consistent and how a failed camera or recorder is reported. The storage estimator is a planning aid, not proof of the final recording capacity.
Connect observation to action
Define who receives an important event and what they are expected to do. During closed hours, a remote reviewer still needs a working escalation contact and an available local response where required. List the actions permitted, the actions prohibited and what happens when the available video is inconclusive.
Accept the system against scenarios
Use the original scenarios to plan commissioning. Review sample views in the relevant lighting, test retrieval, verify access restrictions and record the outstanding items. Keep the approved layout, device list and support route with the handover records. Revisit them after a rack change, extension or recurring fault.
