Smooth Technology equips security checkpoints with walk-through metal detectors and X-ray scanners. The person and their baggage are inspected, objects are detected and located, and a targeted check is decided before passage is authorized. The same principle at every station: inspect, detect, then check.

The ZK-D180 is a walk-through metal detector installed across the passage. A person passes through it once, and the archway signals the presence of metal objects, at the height of the zone where they are.

The ZK-D3180 is an 18-zone walk-through metal detector, with a 5.7" LCD display, LED indicator, 256 sensitivity levels, a people counter, alarms, and a remote control. Same principle as the ZK-D180, with a finer read on where the object is.
Both archways cover the same need — the choice is made with our engineers according to the screening level and the number of people to inspect.

The ZKX6040 is a dual-energy X-ray inspection system. The bag is passed through the tunnel, and the resulting image lets you tell organic materials from inorganic ones — without opening the bag.

The archway inspects every person who passes the checkpoint, with no slowdown to the queue. Selected for systematic screening of staff and visitors.
The X-ray scanner shows the inside of the bag without opening it. Selected when a manual search is not enough, or when the inspection must stay non-intrusive.
From the arrival of the person and their bag to the screening decision, every stage is handled by our engineers.
The traveller and their bag reach the checkpoint
The archway and the scanner review the bag
An object is flagged, in a specific zone
Targeted check, then passage is cleared
Every station is sized, installed, and configured by our engineers so that inspection, detection, and screening work as a single system — and without slowing the flow of people.
Every screening event is timestamped, so the passage of each person and their bag can be reconstructed.
The archway and the scanner work in parallel: several people are inspected at the same time, without holding up the queue.
Multi-zone detection and the X-ray image show where the object is, for a targeted check rather than a full search.
Archway sensitivity is set according to the security protocol in force, from standard screening to enhanced screening.
A single station or a full screening chain: the same approach scales with your site's security level.
