06 Oct When CCTV shows nothing, but stock keeps disappearing

The stock count is short again. Management checks the cameras, reviews the access logs and asks the warehouse team what happened. There is no clear footage of a theft and no single incident that explains the loss.

It is tempting to conclude that the cameras need upgrading. But CCTV can only show what happens within its field of view. It cannot, on its own, explain every incorrect stock movement, process failure or deliberate attempt to conceal a loss.

When stock repeatedly disappears without an obvious explanation, the business needs to investigate the whole movement of the goods, from receipt to dispatch.

Start by establishing what is actually missing

Before focusing on a person, confirm the nature and scale of the discrepancy. Is the same product affected each time? Do losses occur on particular shifts, at one location or during a specific stage of the process?

Compare physical counts with purchase orders, delivery notes, returns, transfers, damaged-stock records and sales or dispatch data. A recording error can create an apparent loss. Equally, a process weakness can provide an opportunity for theft.

The aim is to identify where the recorded quantity stops matching the physical stock. That gives the investigation a narrower and more useful starting point than watching hours of footage at random.

Why CCTV may not reveal the answer

A camera might show goods being moved without showing whether the movement was authorised. Some areas may have blind spots, poor lighting or insufficient coverage. A loss may also occur through paperwork or system entries that make an unauthorised movement appear legitimate.

Consider whether the investigation needs to examine:

• Who can authorise stock adjustments, write-offs and returns
• Whether goods can leave through more than one exit
• How deliveries and collections are verified
• Whether access cards or system accounts are shared
• How contractors, drivers and temporary staff are supervised
• Whether the same discrepancy occurs across multiple shifts or sites

These checks may reveal an innocent explanation, a control failure or conduct that requires a deeper investigation. Do not treat a person’s presence near missing stock as proof that they took it.

Preserve the evidence before changing the process

If you suspect deliberate wrongdoing, secure relevant records promptly. CCTV may be overwritten, access logs may have limited retention periods and witnesses’ memories can fade.

Keep original files where possible, record who collected each item and restrict access to the investigation team. Avoid circulating footage or allegations among staff. If you immediately announce every suspected weakness, you may also make it harder to establish how the loss occurred.

At the same time, take proportionate steps to protect stock and people. The appropriate response will depend on the value of the loss, the evidence available and the risks involved.

When should you consider an undercover investigation?

An undercover investigation may be appropriate when losses continue despite routine checks, several people have access to the affected goods or management suspects collusion. It can also help when established security controls appear sound on paper but are regularly bypassed in practice.

An investigator working within the environment may observe how processes operate day to day, identify recurring breaches and report information that management cannot obtain from a camera or stock report alone. The assignment should have a defined purpose, clear reporting arrangements and an appropriate scope.

SSC Legacy’s undercover workforce investigators assist organisations in identifying theft, misconduct, security loopholes and other workplace risks. Findings can be reviewed alongside stock records, CCTV and other available information to build a clearer picture of what is happening.

Look beyond the immediate loss

Finding out who removed one item may resolve one incident. Understanding how goods repeatedly leave the business can prevent the next loss.

A useful investigation should help management answer questions such as:

• Where does the stock control process break down?
• Which records can be trusted, and which need improvement?
• Are existing security procedures being followed?
• Are staff or contractors able to bypass controls?
• What changes would make future discrepancies easier to detect?

The findings should be assessed fairly. Suspicion is not a substitute for evidence, and any employment or disciplinary decisions require an appropriate process.
