Tech in the Home Team: Seeing is Believing
Every month, we feature how our Home Team scientists and engineers are using Science and Technology to keep Singapore safe and secure.

Whether it’s detecting a security threat or analysing a crime scene, it’s crucial that Home Team officers have the ability to see beyond what the human eye is capable of. Here are just two screening and analytical capabilities that the Home Team has in its arsenal.

Future-ready Checkpoints
In April 2018, the Immigration & Checkpoints Authority (ICA) announced a change to how checks will be conducted for buses and bus passengers at Tuas Checkpoint:
   - Radiographic bus scanners will be deployed to augment the current system of manual checks; and
   - Security checks for arriving passengers will be brought forward, before their immigration clearance. 

These changes will ensure that bus/passenger screenings are more robust.

Here’s how the current screening system works: 
   1.  A bus arriving at Tuas Checkpoint drops off passengers and their belongings at the alighting concourse.
   2.  ICA officers will conduct a thorough manual check of the bus for prohibited or controlled items. 
   3.  The bus driver will then proceed to the bus booth for immigration clearance.
   4.  Meanwhile, the passengers will enter the bus hall for immigration clearance, followed by secondary checks.

And here’s how the new bus/passenger screening system works:
   1. A bus arriving at Tuas Checkpoint will drop off its passengers and their belongings at a new disembarking area.
   2. The bus driver then drives through a radiographic bus scanner, which captures detailed images of the bus. These are relayed to an analysis office and examined for prohibited or controlled items. 
   3. Meanwhile, passengers will enter the bus hall for security checks (involving walk- through metal detectors and X-ray screening) before going for immigration clearance.

These are just some of the benefits of the new system:

Safer and More Robust Clearance: With the bus scanner, ICA officers won’t have to inspect buses manually (e.g. lifting floorboards to look for modified compartments). Each scanned image can also be tagged to a vehicle, stored and used for analytics and training purposes. The new immigration cleara ocess for passengers will also allow ICA officers to detect threats earlier.

Reskilling of ICA Officers: ICA officers who are currently conducting manual checks will be trained and redeployed to perform image analysis. 

The new screening system is scheduled for implementation at Tuas Checkpoint in the second half of 2018.

3D CSI
New tech tools like 3D scanners have changed how the Singapore Police Force preserves, reconstructs and analyses crucial data at crime and accident scenes. Here are just some of the benefits of 3D scanners in crime-fighting: 

Digital preservation and imaging: Entire scenes can be captured and preserved digitally, long after the physical area itself has been cleared. Accurate measurements of crime scenes can also be taken without having to measure the actual physical objects. 

3D analysis and virtual revisits: Crime and accident scenes can be reconstructed and analysed in 3D. Virtual walkthroughs of these scenes can also be performed.
