Everything you need to know about x-ray scanners and human presence detection: Flow Systems’ advanced security solutions
Flow Systems has been a trusted name in security and access control in South Africa for five decades. Among its advanced technologies are x-ray scanners and vehicle-based human presence detection systems, designed to meet the rising demand for secure, efficient screening in high-risk environments.
Here we’ll explore how Flow Systems’ products are used, why they matter and look at key issues related to x-ray baggage scanners, human detection in trucks, and general security x-ray machines.

What is an x-ray scanner?
An x-ray scanner is a security device that uses x-ray technology to inspect the contents of bags, luggage or packages without opening them. Flow Systems offers x-ray scanner baggage solutions ideal for airports, government buildings, courts and corporate facilities.
These machines help detect threats like weapons, explosives and contraband items. Popular models from Flow Systems include x-ray baggage scanners, scanner baggage systems, and security x-rays designed to streamline luggage scanning at airports and magistrate courts, for example.
Where are x-ray baggage scanners used?
- Airports: As an airport baggage scanner, Flow Systems’ technology provides quick, accurate scans of hand and checked luggage.
- Commercial buildings: High-traffic office parks and corporate HQs benefit from the added security of security x-ray machines.
- Correctional facilities: Prevent contraband from entering secure areas.
- Government installations: Ideal for luggage scanning at border posts, embassies and courts.
Flow Systems’ x-ray products meet international safety standards and deliver high image resolution for better threat detection.

Human presence detection in trucks – what does it do?
Flow Systems also offers a vehicle-based human presence detection system designed to detect hidden persons in trucks and other large vehicles. This system, based on seismic vibration sensing, can identify even minute human movement, such as a heartbeat, inside the cargo area of a vehicle.
Key features:
- Advanced seismic sensors detect hidden individuals in vehicles.
- Works in mobile, stationary and portable applications (ideal for ports, border crossings and field operations).
- Passive, non-invasive technology with no harm to people or cargo.
- Measurement time under 2 minutes with high reliability.
- This solution is ideal for security authorities working to prevent illegal immigration, smuggling and unauthorised cross-border movement, where visual inspections are not possible.
