Security Cameras for POS Cash Disputes

A checkout dispute is easiest to investigate when video can show the customer, employee and transaction surface at the same time and can be matched to the POS timestamp.

Best evidence pattern: one tighter transaction view plus one contextual view of the checkout lane.

What the camera should prove

Which customer and employee were involved.
Whether cash, card, receipt, product or change changed hands.
Approximate sequence and timing of the transaction.
Whether another person entered the interaction.

Avoid the ceiling-only failure

A steep overhead camera can show hands but weak faces. A low eye-level camera can show faces but miss the counter. Offset the camera so both transaction surface and usable face geometry remain in frame.

Correlate video with POS data

Clock synchronization matters. If the NVR and POS timestamps drift, finding the correct transaction becomes slower and less defensible. Keep system clocks synchronized and retain footage long enough for delayed disputes.
