In this paper, we present the architecture and the main functionalities of an innovative security system and its installation details in the Metrocampania undeground railway. Heterogeneous intrusion detection, access control, intelligent video-surveillance and sound detection devices are integrated in a cohesive Security Management System (SMS). The core of the SMS consists of an advanced web-based software application featuring an effective and user-friendly interface. System architecture is distributed and hierarchical, with both local and central control rooms collecting alarms according to different scopes and responsibilities. The system is able to protect stations (accesses, technical rooms, platforms, etc.), tunnels (portals, ventilation shafts, etc.), trains and depots. Presently, the system is being tested in the Metrocampania regional railway.

Intelligent video-surveillance
FEATURES
- Extensive coverage of areas normally
not watched by CCTV
- Face detection at the turnstiles using
very high resolution cameras
- Videoanalytics significantly improves
effectiveness, providing alarms for:
- unattended object
- yellow line crossing (platform)
- loitering (near toilets, elevators, etc.)
- person in area (e.g. tunnel portals)
- camera blinding
DEVICES
- ≈ 500 high-resolution cameras
(Day/Night, Megapixel, IR, PTZ)
- 60 Digital Video Recorders in
redundant configurations
- 5 videoanalytics blade-servers

4. Intelligent sound detection
FEATURES
- Active in all internal public areas,
except track area
- Recognizes abnormal events which
videoanalytics is not able to detect
- Only detection, no recording (no
privacy concern)
- Learning-based detection of:
- screams
- glass break
- gunshots/explotions
DEVICES
- 80 high sensitivity microphones
- 10 audioanalytics servers
Intrusion Detection / Access Control
FEATURES
- Access control based on proximity badge
readers on all doors of technical/control rooms
- Multi-technology ventilation grill protection
(magnetic contacts, vibration detection cables,
triple technology volumetric detectors)
- Tunnel portal protection by active IR
barriers
DEVICES
- 250 proximity badge readers
- 200 volumetric detectors
- 40 vibration detection cables
- 20 active infrared barriers

7. Conclusions and future works
• A real-time demonstration of the SMS has been performed for the first time on the
9th of May during the technical visit of the ASSTRA’09 conference
• The Metrocampania SMS system is currently working on a temporary post, but it will
be fully operational as soon as the central security control room will be available
(currently under construction)
• Intelligent sound detection showed very high reliability, since it is not conditioned by
the number of passengers and it also learned ordinary noises like PA ringtones
• Videoanalytics is undergoing extensive on-the-field testing to raise the Probability Of
Detection (POD) while lowering the False Alarm Rate (FAR)
• For other projects, integration of CBRNE (Chemical Bacteriological Radiological
Nuclear Explosive) detectors and WSN (Wireless Sensor Networks) technologies is in
progress
• On-going research on early warning and decision support to improve situational
awareness (to be integrated in the SMS)
