Section 01

Define the Loss-Prevention Question

Define the transaction event and the associated handling context to review, such as an authorized refund or void event. Video should support a specific question rather than collecting every available data field. A camera view alone does not provide searchable transaction integration.

Turn the answer into a working record using Event, Review question, Camera, Necessary data.

Section 02

Specify the Actual Interface

No. The POS, middleware and recording platform need a supported interface and compatible data format. Define the event fields, version and delivery method. Network connectivity or a generic analytics label does not establish transaction-overlay or search capability.

Use POS, Interface, Fields, Platform, Version to compare options on the same basis. Keep product capability, project assumption and operating responsibility in separate columns.

Section 03

Align Time and Camera Mapping

Transaction and video timelines must align closely enough for the intended review. Map each terminal to the correct camera and handle timezone or clock changes. A correct event identifier can still lead to the wrong clip when camera mapping or timestamps are inconsistent.

The project output should make Terminal, Camera, Time source, Offset handling traceable from input to acceptance.

  • Confirm the answer to: Why is time synchronization critical for POS video?
  • Record the project fields: Terminal / Camera / Time source / Offset handling.
  • Keep product capability, project assumptions and site responsibility in separate records.

Section 05

Protect Transaction and Video Access

No. Transfer only information needed for the approved purpose and permitted by applicable requirements. Keep sensitive payment and customer information out of unnecessary video records. Apply access and retention controls to both transaction events and related footage.

Review Field, Needed purpose, Access, Retention, Exclusion with the party that will operate or maintain the system.

Section 06

Plan the Full Integration Infrastructure

Include cameras, recording, supported integration components, storage, operator workstations and network and power dependencies. Local recording and POS operation may have separate outage requirements. NexPro-Link can support equipment coordination while the actual integration functions and ownership remain explicitly specified.

Use Component, Function, Interface, Power, Scope as the handoff between design and procurement.
