Lanaccess has developed an integration with the Swedish manufacturer Axis to enable forensic searches based on individuals’ clothing.
Our Lanaccess Suite VMS software facilitates the management of these searches from any browser, eliminating the need for complex configurations.
Applications
By using metadata extracted from AXIS cameras, the Lanaccess VMS enables the identification of individuals based on:
- A specific garment, such as dresses, jackets, shorts, skirts, t-shirts and trousers.
- A range of colour options, including a combination of colours or a dominant colour.
The intuitive and user-friendly selector allows users to toggle between AND and OR options to refine clothing-type searches. This enhances both the precision and efficiency of specific and broad searches.
The detailed visual representation displays the likelihood of a match for each detected colour, improving transparency and confidence in the data.
These capabilities can be further enhanced with our advanced LAVA analytics, providing highly accurate analysis solutions. Among the LAVA-compatible algorithms, notable ones include LAVA APPEARANCE for anonymous facial detection and LAVA PROTECT for perimeter security.
AND/OR Function
The AND/OR filtering selector allows users to combine different types of clothing in their searches. For instance, they can search for upper-body garments in multiple colours and lower-body garments in other colours or conduct searches for each clothing type separately.
Search for a subject by filtering for a red dress or jacket
Previous filtering result
| Search type | Practical example |
|---|---|
| Precise (AND) | A person wearing a red upper-body garment and a green lower-body garment. |
| General (OR) | A person wearing a blue upper-body garment or a blue lower-body garment. |
Technical implementation
The integration with the security camera manufacturer follows the ONVIF M standard, a protocol that defines how metadata is transmitted and used to ensure interoperability between video surveillance systems. ONVIF also enables the management of MQTT signals, a lightweight messaging protocol for exchanging data between IoT devices.
In addition, we support this capability with robust cybersecurity measures. For example, we use secure protocols such as HTTPS and FTPS, combined with granular authentication systems, to ensure that only authorised users can access the data.
Key Development Features:
- Enriched data: by adding information on visual characteristics, operators gain a greater level of detail, improving the effectiveness of searches and investigations.
- Resource optimisation: the filtering system prevents unnecessary data processing, ensuring efficient system performance.
- Probability filtering: the VMS applies probability-based filtering, discarding colours with low confidence levels and prioritising relevant data. This ensures higher-quality results.
Conclusion
The integration with Axis cameras not only enhances advanced detection and search capabilities but also significantly improves accuracy and speed in incident management. These features combine interoperability, cybersecurity and efficiency, transforming video surveillance into a strategic and adaptable tool.
