Protecting remote mobile sites

After an ODET Perimeter Intrusion Detection System (PIDS) has been installed for a period of one year, no incidence of theft and vandalism has occurred at a mobile operator’s tower infrastructure site, located remotely on a hill.

This is remarkable, considering that this particular site was targeted by thieves more than once, destroying equipment shelters, removing batteries and cutting ‘baseband’ or ‘IF’ copper cables from the shelters to the radio equipment, located on the mast.

The perpetrators always gained access to this site by forcing the palisade fencing apart. Because of the remoteness of this site, these criminals had enough time to completely ransack the installation. Alarm systems that were installed inside the enclosures only triggered after the enclosure was breached. This alarm was relayed to a security company, who blindly responded to this event not knowing the exact nature of this incident. Sending out a security officer and his colleague to such an alarm might be dangerous as they would not know the number of perpetrators involved in this break-in and the threat level they might pose.

ODET Systems Africa evaluated the situation at this site, considering the classic approach of the Five D’s namely:

• Denying access by the visible barrier of the repaired palisade fence.

• Detecting tampering with the palisade fence and access gate to site (ODET PIDS).

• Deterring the perpetrator/s by activating a light/alarm in conjunction with a video camera, sending the alarm event detail with a picture to a network operation centre (NOC), as well as to other interested parties via an message on a smart phone (ODET PIDS).

• Delaying the perpetrator by making ingress into the site a difficult as possible thereby buying time to:

• Defend the site by sending out a security response team geared for the threat level posed by the alarm incident.

ODET’s PIDS proved to be a reliable and valuable component to a layered security approach in countering this security treat.

The ODET system deployed in this application consists of an ODET 1 single zone processing unit, available in a nineteen inch rack mount format. A multimode fibre optical cable is used as a sensing medium, which is mounted on the fence and gate. The system also provides input/output contacts for further configurations if required. One such contact output, switch on a LED floodlight and alarm, if an alarm event is triggered (deterring function). The ODET system also connects to a fish-eye video camera, allowing control of the picture/video feed.

The alarm events, video feed and other functions are transmitted via an IP network connection to a security management system at the NOK. System maintenance and other analytics pertaining to this site, is also communicated via this network.

The image shows alarm events caught and recorded by the ODET system. All these events were of an unauthorised nature and these individuals were deterred by the alarm and lights the system triggered.

ODET is of the opinion that this particular system’s configuration and deployment caused confusion and doubt in the minds of potential criminals, thereby completely deterring any further attempts at vandalising this site. The company says this technology can form an important part in the continuing fight against lawlessness in South Africa and elsewhere, especially regarding the threat mobile network operators, telecommunication companies and other infrastructure operators, having remote locations, face daily.
