POS + Video Transaction Auditing — See Every Exception, Every Day
The foundation of DohShield's loss prevention program. Trained human reviewers pull your POS exception reports daily and correlate every flagged transaction against synchronized video footage — building investigation-ready evidence packages when activity doesn't add up.
What Is POS + Video Transaction Auditing?
POS + Video Transaction Auditing is the process of systematically reviewing POS exception reports — voids, no-sales, refunds, discounts, low-dollar transactions, and other anomalies — and correlating each exception against synchronized security camera footage to determine whether the transaction was legitimate or suspicious.
Most businesses already generate exception reports from their POS systems. The problem is that nobody reviews them. A typical convenience store generates 15–40 exceptions per day, and a busy QSR can generate over 100. These reports pile up in inboxes and management dashboards, never opened, never acted on. Meanwhile, employees learn which transactions go unmonitored — and exploit the gap.
DohShield eliminates this gap with dedicated human reviewers who pull your POS exception data every day, locate the corresponding video footage, and assess whether each exception was a normal business operation or a potential incident. When they find something, they don't just flag it — they build a complete evidence package with the video clip, POS receipt, timestamp, employee ID, and a written narrative. The result is documentation you can act on: terminate with confidence, prosecute when needed, or address policy violations before they become patterns.
This is fundamentally different from automated loss prevention software that generates alerts you have to investigate yourself. DohShield is a fully managed service — we do the watching so you don't have to.
How POS + Video Auditing Works
From system connection to evidence delivery, here's the daily workflow our reviewers follow for every location under DohShield's coverage.
POS Data Extraction
We pull exception reports from your POS system every morning. Voids, no-sales, refunds, discount overrides, manual price entries — every transaction that deviates from a standard sale gets flagged for review. No manual export required on your end.
Video Correlation
Each flagged exception is matched to the corresponding video footage using timestamps and register location. Our reviewer watches what actually happened at the register during the transaction — the employee's hands, the customer interaction, the items on the counter, and the register screen.
Assessment & Classification
The reviewer determines whether each exception is legitimate (a genuine customer return) or suspicious (a void with no corresponding customer). Suspicious activity is classified by type: void abuse, sweethearting, safe drop issue, policy violation, or other. Each classification includes a severity rating.
Evidence Package Creation
For confirmed incidents, the reviewer compiles a complete evidence package: synchronized video clip, POS receipt screenshot, timestamp, employee ID, register number, and a written narrative describing what occurred. Packages are formatted for HR review, termination proceedings, or law enforcement referral.
Transaction Types We Review Daily
Every POS exception category is audited against video. Here are the most common exception types — and what our reviewers look for in each.
Voids & Post-Voids
Voids are the #1 tool for register theft. An employee rings up a sale, collects cash from the customer, then voids the transaction — keeping the cash with no record of a completed sale. Post-voids are even more concerning: the transaction completes, receipt prints, and then gets voided after the customer leaves. Our reviewers watch the video for every void to determine whether a customer was present, whether items were returned, and whether the void matches a legitimate business reason.
Red flags we watch for: Voids with no customer present, voids immediately followed by a cash-drawer open, voids on items that were visibly taken by the customer, and high void frequency on specific shifts or registers.
No-Sale Opens & Cash Drawer Access
A no-sale is when the register drawer opens without a transaction being processed. Legitimate no-sales include making change for a customer or correcting a cash count. But they're also the simplest method for register theft — open the drawer, take cash, close the drawer. Our reviewers check the video for every no-sale to verify whether an exchange with a customer occurred or whether the drawer was opened without justification.
Red flags we watch for: No-sales with no customer at the register, repeated no-sales during low-traffic periods, no-sales immediately before or after shift changes, and employees positioning their body to block camera view during a no-sale.
Refunds & Returns
Fraudulent refunds are one of the most sophisticated forms of employee theft. An employee processes a return for an item that was never purchased — or was never actually returned — and diverts the refund to their own payment card or issues a cash refund they pocket. Our reviewers verify that every refund corresponds to an actual product return by checking the video for the returned item, the customer interaction, and the disposition of the refunded merchandise.
Red flags we watch for: Refunds with no visible product return, refunds to payment methods that differ from the original purchase, refunds processed when no customer is present, and high refund volume from a single employee compared to peers.
Discounts, Price Modifications & Low-Dollar Sales
Unauthorized discounts and manual price changes are a primary mechanism for sweethearting — giving friends, family, or regular customers a better price at the business's expense. Our reviewers flag any discount applied without manager approval, any price override below standard cost, and any unusually low-dollar transactions that may indicate items were rung at the wrong price intentionally.
Red flags we watch for: Employee discount codes used for non-employees, price modifications that reduce totals by more than 20%, items manually entered at prices significantly below shelf price, and patterns of low-dollar sales to the same customers.
What's in an Evidence Package
Every confirmed incident receives a complete documentation package — formatted for HR, legal, or law enforcement use. Here's exactly what each package contains.
Synchronized Video Clip
A timestamped video clip showing exactly what occurred at the register during the exception. Clipped, annotated, and ready for review — no scrubbing through hours of raw footage.
POS Receipt Screenshot
The complete POS exception record showing the transaction in question — item details, amounts, void/refund type, and the employee ID who processed it.
Precise Timestamp
Exact date, time, register number, and store location — synced between the POS record and the video footage for airtight documentation.
Employee Identification
Full employee ID, register assignment, shift information, and — when available — manager-on-duty during the incident. Tied to video for visual confirmation.
Written Reviewer Narrative
A detailed written description from the reviewer explaining what occurred — what the POS data shows, what the video reveals, and why the activity is classified as suspicious.
Pattern Report (When Applicable)
For repeat offenders, a timeline showing every documented incident: dates, amounts, total estimated loss, and escalation recommendations — building the progressive case for action.
Who Benefits from Daily POS + Video Auditing
Any business with a POS system and security cameras can benefit — but these industries see the fastest ROI from managed daily transaction auditing.
Convenience Stores
High transaction volumes, cash-heavy operations, and frequent employee turnover make c-stores the highest-risk environment for register theft. The National Association for Shoplifting Prevention reports that employee theft accounts for 42% of all inventory shrinkage in retail — and c-stores sit at the center of this problem. Daily POS video auditing catches the voids, no-sales, and sweethearting that slip through unnoticed on overnight and early-morning shifts.
Restaurants & QSR
Restaurant theft is notoriously difficult to detect because of the speed and complexity of operations. According to the National Restaurant Association, 75% of inventory shortages in restaurants stem from internal theft — not customer shoplifting. POS video auditing catches server tab manipulation, unauthorized comps, voided orders that were actually served, and the discount abuse that can add up to tens of thousands per year across locations.
Bars & Nightclubs
Bars lose an estimated 15–20% of profits to theft and carelessness. Bartenders overpour, give away free drinks, use the phantom bottle scheme, or simply don't ring every sale. Because bartending happens at speed with poor lighting and distracting environments, traditional monitoring fails. Daily POS video auditing catches the gap between what was served and what was rung — the measurable loss that hits your pour cost every month.
Frequently Asked Questions
DohShield integrates with virtually every major POS platform used in convenience stores, restaurants, bars, gas stations, and retail environments. This includes Verifone, Gilbarco/Passport, NCR, Toast, Square, Clover, Revel, Aloha, MICROS, and many others. If you have a POS that generates exception reports, we can work with it. During onboarding, our technical team handles the integration remotely — no changes to your existing setup required.
The number of exceptions depends on your plan tier and transaction volume. Silver plans cover 100 exception reviews per month, Gold covers 125, and Platinum covers 200. For most single-location convenience stores, the Silver plan provides sufficient coverage. Multi-register, high-traffic locations typically benefit from Gold or Platinum. We prioritize the highest-risk exceptions first — voids, no-sales, and refunds always get reviewed before lower-risk items like discount overrides.
Our reviewers access recorded footage, not live feeds. We retrieve the specific video segments that correspond to flagged POS exceptions. This means we're only watching the time windows around transaction anomalies — not monitoring your store continuously. Our access is encrypted, logged, and restricted to authorized reviewers. We follow strict data handling protocols and can provide our security documentation upon request.
We work with a wide range of camera systems and quality levels. Ideally, you want at least one camera with a clear view of each register area. Most modern IP camera systems provide sufficient quality for transaction auditing. During the onboarding assessment, we'll evaluate your camera setup and let you know if any adjustments would improve audit effectiveness — but in most cases, your existing cameras are fully adequate.
Most locations are fully onboarded and receiving daily audits within 5–7 business days. The process involves POS integration setup (remote, no on-site visit needed), camera system connection, reviewer training on your specific store layout and policies, and a calibration period where we establish your baseline exception patterns. Multi-location deployments are staged to ensure quality — typically 5–10 locations per week.
