OpSEM is an Operational Screening Efficiency Monitoring System that integrates seamlessly with all types of X-Ray Machines to create a more efficient screening process.

How does OpSEM improve checkpoint efficiency?

OpSEM provides solutions to a number of issues that regularly affect the speed and efficiency of the security checkpoint.

Problem 1: Overcrowding

In many security applications, liquids, large electronic items, belts and shoes must be screened separately.

Once screening has taken place, passengers must re-pack these items within their bags or, in the case of shoes and belts, put them back on.

This causes delays as the screener must stop screening while these items are removed and space is freed up on the conveyor belt.

OpSEM Solution

With OpSEM added to the x-ray machine, the searcher is able to view on their screen the reason why the screener has stopped a bag for search.

This means that the screener and searcher can be placed further away from each other as they do not need to communicate.

This enables you to leave more space within the checkpoint for passengers to collect their items and re-pack.

Problem 2: Screener/Searcher Communication

When a searcher collects a bag, they must ask the screener what they are searching for and where, within the bag, they should be looking.

This distracts the screener from their own job as they must look away from their screen and talk to the searcher.

As a result, the operation slows down and screeners are more likely to lose concentration and miss a threat.

OpSEM Solution

With OpSEM, bags are placed within trays that each have a unique bar code.

If the screener identifies a threat, they mark on their touch screen the area and reason for search.

The searcher gathers the tray and scans its barcode; this brings up on their monitor exactly what the screener has marked.

All this means that the searcher knows exactly what type of threat they should be looking for without having to distract the screener from their task.

Problem 3: Little Information Provided to Searcher

When a searcher receives a bag, they have no idea where to start searching. If the bag is large and contains many items, the search procedure can take a long time.

OpSEM Solution

OpSEM provides the searcher with the x-ray image of the bag along with the area for search that has been marked by the screener.

This gives them an approximate area where they can search which will save them time, especially when searching large bags with any items within them.

Problem 4: Unable to Identify Performance of Screeners at Checkpoint

Within most security checkpoints there is no way of identifying whether a screener is doing a good job or not. This kind of information is important as too many false alarms can cause delays and passengers to feel that they are getting poor service.

OpSEM Solution

OpSEM is able to calculate the success rate and false alarm rate of screeners when identifying prohibited objects. Mapping a screener’s professional capabilities ensures management can use the time allocated for training more efficiently.

By understanding which prohibited items the screener has difficulties with, management is able to design training that focuses on improving the weaknesses of the screener while minimizing the time spent on training them on items that they already identify effectively.

Problem 5: Passengers Delayed

Slow checkpoints mean passengers spend more time queuing than shopping in the duty free shops.

OpSEM Solution

By speeding up the operation, OpSEM ensures shorter queues and satisfied passengers who will have more time to spend money in the shops.
