Product overview
Technical descriptions
The descriptions and static frames below explain the illustrated arrangements, including alternative views and selectable scenarios. Screenshots show the website examples; their accompanying text identifies what each example represents.
In these operational descriptions, visual observations mean information derived by applying machine learning to visual information: images, video frames, depth images, point clouds or inspection imagery. Models can detect and segment people and objects, estimate pose and placement, track movement, recognise actions, retrieve appearance candidates and identify anomalies. Sensor fusion associates selected visual outputs with other sensor measurements and operational records. Decorative drawings and website simulations remain illustrations rather than model outputs. Sensor-fusion methods and technology catalogue.
Connected sensor field
An animated spatial field introduces the combination of observations from different sources.
View the product example · Permanent figure link
The field draws a schematic environment, moving observations and connections between observations. Their positions and motion communicate the idea of following activity in a shared spatial representation rather than viewing each source independently.
The animated geometry introduces the connected operational picture. The individual product descriptions below explain the arrangements represented by the overview.
SensorSync product illustration
Observations connect through an analysis stage to operational outputs.

The left side represents people and objects, interactions and equipment usage. Lines connect these observations to a central SensorSync AI and Flow stage; the outgoing connections represent information used to understand operations and choose a response.
The moving signals illustrate information flow. They do not specify a network protocol or processing delay. The compact navigation symbol uses the central part of the same drawing as a static vector illustration.
AIVA product illustration
A kiosk combines observation, passenger guidance and a connection to the lane.
View the product example · Permanent figure link
The schematic shows a passenger-facing AIVA module, a preparation area, a tray and a speech interaction. Observation and guidance are represented together so that preparation can be checked and the passenger can receive a relevant instruction.
The visual introduces the divest and passenger-assistance functions. Detailed examples describe tray loading, preparation guidance, queue assistance and terminal services. Animated scan and speech marks represent observation and guidance; the menu uses a still vector version.
NexuSec product illustration
Candidate appearances connect a search to relevant video.
View the product example · Permanent figure link
Several camera-style frames contain person outlines. A highlighted central frame, scanning line and connecting marks represent the retrieval and review of candidate appearances from footage.
A candidate appearance is a result for operator investigation. The illustration does not establish identity. The detailed search examples distinguish a reference-image query from a separate written-description query and return the operator to source footage.
Deeper Scan product illustration
A layered inspection drawing represents viewing beneath an object surface.
View the product example · Permanent figure link
The drawing combines an inspection enclosure, internal object geometry and scan planes. Movement through the geometry represents the examination of internal structure in CT or X-ray inspection.
This is a schematic of the product family, not a captured scan or a dimensional cabinet specification. Separate technical descriptions cover browser viewing, annotation and model development, object insertion and cabinet-based device comparison.
Security illustrations
Four product illustrations describe complementary contributions to security.
View the product example · Permanent figure link
SensorSync connects sensor observations around an event. AIVA connects preparation checks with guidance. NexuSec links an appearance or event to source video. Deeper Scan shows inspection of internal structure. These are different contributions, rather than a claim that every product performs every task.
The three selectable outcomes change the explanatory text and all four drawings. Every outcome is represented here as static images and text, independently of the selection on the homepage.
Efficiency illustrations

The three selectable outcomes change the explanatory text and all four drawings. Every outcome is represented here as static images and text, independently of the selection on the homepage.
Performance illustrations
Four product illustrations describe complementary contributions to performance.

SensorSync distinguishes live observations from a forecast. AIVA connects a passenger question to assistance. NexuSec links an event to timing and footage. Deeper Scan connects labelling, model training and testing.

Connected expertise
Software, AI and security expertise are brought together around a system.
View the product example · Permanent figure link
The architecture drawing places NWPRO at the centre of connected capability nodes. Animated paths and rings indicate collaboration between software, artificial intelligence, security systems and infrastructure.
The drawing is an explanation of connected delivery capabilities. It is not a physical network topology or an assertion that the displayed connections are live telemetry.
Company location map
A schematic map links the United States, United Kingdom and Germany.
View the product example · Permanent figure link
The visual places labelled markers for the three company locations and joins them with curved routes. Pulses and moving packets are decorative indications of connection between the locations.
The map is geographic presentation artwork. It does not identify sensor coverage, customer sites, network routes or measured traffic.
Visual machine learning, sensor fusion and screening technologies
The following describes possible arrangements across the illustrated product families. The catalogue is broad and non-exhaustive. Sources may be used individually or in selected combinations; not every technology is integrated, demonstrated or appropriate to every product. Specialist and research techniques are identified separately from routine checkpoint equipment.
From visual information to an associated event
Acquire live or recorded visual information and selected sensor or screening outputs. Retain source identifiers, timestamps, calibration, coordinate frames, quality and available uncertainty. Processing may occur at the sensor, on an edge device, on premises, in the cloud or across these locations.
Apply trained visual models to suitable frames, image sequences, depth data, point clouds or scan volumes. Examples include object detection, instance or semantic segmentation, keypoint and pose estimation, multi-object tracking, optical flow, activity recognition, visual-language models, image or text embeddings, appearance retrieval, OCR and anomaly detection. Models and training data are selected for the modality and task; an ordinary camera does not inspect concealed contents.
Align sources in time and, where applicable, transform them into a shared spatial representation. Associate observations using time, position, motion, identifiers, appearance and task context. Fusion may combine raw measurements, extracted features, tracks, model scores, decisions or workflow events, using rules, statistical estimation, probabilistic or Bayesian methods, state estimation, learned multimodal models or combinations.
For a lane example, visual machine learning identifies a passenger loading a tray and records subsequent interactions. Spatial measurements help follow the passenger and tray; RFID or a visible code can supply a tray identifier. Screening equipment contributes scan, alarm and completion records. Association connects these to the relevant passenger, tray, article and required task, retaining links to source video and images for the interaction flipbook.
A configured workflow can request correction, a recheck or staff review, and can communicate permitted hold or release requests. Missing, conflicting, delayed or low-quality evidence remains unresolved rather than being treated as verified completion. A visual action or equipment passage alone does not establish a successful screening result. Permissions, recipient verification, equipment interfaces and approved site procedures govern any handover or control.
