The HSR.4B system is designed to detect potentially dangerous objects on individuals passing through the inspection area. When a threat is detected, the operator’s screen displays photo images with suspicious objects highlighted using different frames.
Below are the main types of alarm signals.
1. Reflection Mode Alarm
In reflection mode, HSR analyzes a radio wave image reconstructed from the scattered signal. If the system identifies a potentially dangerous object, its location is shown in the photo with a red rectangle.

The dangerous object is highlighted with a red rectangle.
2. Transmission Mode Alarm
In this mode, the system uses images from side-view video cameras. Suspicious objects are detected by analyzing the transmitted radio wave signal passing from one pillar to another. If such an object is detected, its exact location may not always be shown on the image, therefore all individuals who trigger this type of alarm must be inspected.

3. Metal Detection Alarm
When a large metallic object is detected on a person, the system generates an alarm. The image displayed on the operator’s screen shows the detected object highlighted with a violet frame. This decision is based on data received from magneto-sensitive sensors.

4. “Out of CONOPS” Alarm
This alarm occurs when a person passing through the inspection zone is partially or fully obscured by others. In such cases, HSR cannot determine with certainty whether the person carries a dangerous object. These targets are highlighted with an orange frame.

By default, the orange mode (Out of Conops) is disabled.

It is recommended to perform an additional inspection of the target, and, if possible, reduce the number of people entering the inspection zone at the same time to avoid similar situations.
