Disputed Delivery? Find the Loading-Bay Footage Fast

When a supplier says they sent 40 cartons and your team counted 38, start with the receiving paperwork, not the video. The delivery note, gate log, and receiving scan give you the dock and the minutes to review. Check the recorder's clock, pull the gate, dock, and counting cameras for that window, then lock the clip before it is overwritten.

Most warehouses already have cameras pointed at the loading bay. What they usually lack is a routine for using them when a delivery is questioned. That routine decides whether you have evidence on the third day or an argument on the fifteenth.

Why do delivery disputes stall?

The claim rarely arrives while the truck is still at the dock. Someone notices the shortage while putting stock away, or the supplier's invoice doesn't match the receiving record a week later. By then three things work against you:

• The footage may already be gone. Recorders overwrite the oldest video when the disk fills. A retention period that looks like 30 days on paper can be 12 in practice, as explained in the CCTV storage sizing guide.
• Nobody knows which minutes to watch. "Tuesday morning, the Surabaya supplier" can mean four hours across three dock doors.
• The timestamps don't agree. The scanner says 09:12, the recorder says 09:16, the gate book says "around nine".

The stakes are not small. Verisk CargoNet counted 677 supply chain theft incidents in the US and Canada in Q2 2026, with estimated losses of US$304.6 million, up from US$135.7 million a year earlier (FleetOwner, 10 August 2026). The report also notes business email compromise — criminals posing as a company in email — being used to redirect shipments. Those are North American figures, not Indonesian ones. The lesson still travels: most losses are argued over paperwork and timing, and the side with the cleaner record usually wins.

Which records point you to the right minutes?

Every delivery leaves a trail before it reaches the camera. Collect it first, then turn it into a time window and a list of cameras.

The gate log usually gives the widest window, and the receiving scan the narrowest. If the scan shows unloading from 09:05 to 09:40, review from a few minutes before the truck reversed in until it left the gate.

Which cameras does one delivery need?

One camera rarely tells the whole story. A delivery passes through three places, and each answers a different question.

The counting area is the camera warehouses most often skip. A dock-door camera mounted high shows forklifts moving, but not whether a pallet held 38 or 40 cartons. If counting happens on the floor in front of a fixed camera, the count itself becomes part of the record.

Analytics can help you find movement faster, but it will not detect a missing carton on its own. Treat any promise of automatic loss detection with caution; the CCTV analytics guide covers how to test such claims on your own site.

How do you line up the clocks?

Before you trust any timestamp, measure how far each recorder's clock is from a reliable reference, such as a phone set to network time. Write the offset down next to the incident. A recorder four minutes fast is still usable evidence once the difference is documented; an undocumented offset is easy for the other side to attack.

Do the same for the scanner or warehouse system. If the receiving system runs on a server synced to network time and the recorder does not, the server time is usually the better anchor. Why clocks drift, and how to prove a clock was right on a given day, is covered in the article on clock drift and timestamp evidence.

What can the footage prove, and what can't it?

Footage shows what happened in front of the camera. It does not show what happened before the truck arrived.

A recent US case makes this clear. A retailer received five loads of cheese with fewer pallets than its purchase orders listed. Gate video from the yard system tied all five loads to one truck and one driver, and supported a claim of about US$60,000. Yet the footage did not show where the pallets went missing: at the supplier's loading, in transit, or after arrival (FreightWaves, 2 October 2026).

That limit shapes what your team should do at the dock:

• Write the shortage on the driver's copy before signing. "2 cartons short, pallet 3 wrapping torn" carries far more weight than a generic stamp.
• Photograph the seal number next to the delivery note number.
• Count in front of the counting camera, not on a table outside its view.

With those three habits, the video confirms a written record. Without them, the video is asked to prove everything alone.

How do you keep the clip usable?

Finding the clip is half the job. It also has to survive until the dispute is settled, and the other side has to be able to trust it.

1. Lock or protect the clip on the recorder so overwriting cannot remove it. Most recorders and video management software (VMS, the application that manages cameras and recordings) offer bookmarks or protected recordings.
2. Set retention longer than your claim window. If suppliers can raise shortages up to 14 days after delivery, 10 days of footage is not enough.
3. Export from a personal account and log who exported it, which cameras, the time range, and the clock offset. A shared login makes the export harder to defend. The CCTV user access guide shows how to split accounts by role.
4. Keep the original export unedited. Make working copies for viewing. Some cameras can sign the video itself so a recording can be traced back to the camera and checked for tampering; Axis calls this signed video. If your cameras support it, turn it on before you need it.

Sharing a copy with a supplier or carrier follows the same care as any other footage request: view it together first, then hand over a copy with a record. The hotel CCTV workflow describes that approval step in more detail.

What should you prepare before reviewing your setup?

List your dock doors, the cameras that cover the gate, each door, and the counting area, and the recorder each camera writes to. Add your actual retention period, how far each recorder's clock sits from network time, and the longest claim window in your supplier contracts.

On the Pantau CCTV management project, operators work from the areas assigned to their account, jump to motion events on the timeline, and their activity is recorded per user. That is one example of a system built around a site's workflow; many VMS products already offer similar features, so reconfiguring what you have may be enough.
