ZigBee Solution for Building Insurance Industry
What Value Can Wireless Sensor Network (WSN) Technology Offer The Building Insurance Industry?
Insurance Industry Today
Most insurance companies today face an uncertain future: Growing losses, exposed equities,
and weakened reserves. Industry visionaries are seeking new solutions and technologies that
will secure a competitive edge. WSN is at the forefront of these groundbreaking solutions, and
those who adopt this emerging technology are building a solid foundation for future success.
The ultimate value of WSN implementation is the data collected from sensors. Possession of real
time data offers insurance companies significant advantages:
Antiquated Claim Assessment Process
Currently claim assessment may take anywhere
from six months to five years. At least two
professional engineers are required. These
engineers must go out in the field and take
measurements, collect data, and generate
reports manually.
- Minimized Risk
- Reduced Operations Costs
- More Accurate Pricing
- Claims Settlement Process Efficiency
- Loss Prevention
- Enhanced Customer Service
- Value-added Products and Services
- Information Brokerage
Case in Point: Wireless Sensor Networks (WSNs) Deployed to Monitor Building Subsidence*
Opportunity: As the world's largest independent provider of claims management solutions to
insurance companies, Crawford & Company wanted to reinforce its market-leading position by
implementing a new technology. WSN was the clear choice. The next step was to find a partner
who had the required WSN expertise. BOX telematics, one of the UK's most experienced and
respected telemetry and telematics providers, was chosen to coordinate Crawford &
Company's WSN implementation. BOX provides proven end-to-end "wire-free" telemetry and
telematics solutions for many customers in various sectors. In order to ensure long-term
interoperability, the decision was made to develop a standards-based solution.
* - Subsidence is essentially a downward movement of the ground supporting a building. It is
especially dangerous when the movement is uneven, from one part of the building to another.
Subsidence can be caused by certain soils, such as clays; vegetation; leaking drains; and
various types of ground movement, i.e. heaves, landslips, etc. If left unchecked, subsidence may
result in structural damage, when cracks appear on the building's walls, particularly around
doors and windows. Subsidence presents a serious problem for building owners. Every year, total
subsidence damage is measured in hundreds of millions of dollars. Manual inspection is timeconsuming and costly; usually requiring two engineers to go on-site to inspect the building. Due
to the high cost of manual labor, inspector visits are done on a weekly basis at best, which does
not amount to efficient monitoring. Automated building subsidence monitoring solves this
problem by enabling timely action that helps prevent serious damage.
Challenge: To deliver a working building subsidence monitoring solution, fully certified and tested
for use in the UK and European theatre, the following requirements must be met:
- The tilt sensor nodes must form a self-organizing, self-healing ZigBee network;
- Data collection must be performed via GPRS gateway;
- The sensor network must meet rigid power consumption requirements; Max. power
consumption per year is 2500 mA/h for each node, assuming that test mode is not longer
than 30 minutes a year;
- The battery must be fitted to ensure that a technician can remove and fit new batteries
without interfering with other system components;
- Battery Life must exceed 12 months; Battery Type: AA type, 1,5 V. Battery capacity must be
not less than 300mAh;
- Scalability (50+ nodes).
The BOX telematics system will be collecting, logging and uploading data to the Box Gateway
(WWW) on a daily basis. Data will be gathered and transmitted by the SlaveBOX wireless nodes at
pre-determined intervals via the Zigbee standard protocol.

Solution: BOX telematics partnered with MeshNetics, the wireless sensor technology provider &
802.15.4/ZigBee expert, and jointly developed a wireless sensor solution that allowed remote
building measurement. Customized MeshNetics MeshBean sensor boards, running eZeeNet
networking stack firmware, were used as the hardware platform. The hardware set included the
following:
- Single Sided PCB (a customized MeshBean platform). The PCB was single sided for easy mount options into suitable enclosure;
- Protective Enclosure. The unit was housed in a suitable IP65 enclosure that met required standards and also featured convenient access for battery exchanges. The unit included a solid wall mounting bracket to ensure that the node would not move during its operational phase;
- RS232 Interface sensors. The RS232 interface communicated with the sensor on wake up periods;
- RS232 Interface for BOX. The RS232 interface communicated with the BOX Unit;

A convenient web portal was set up to provide an easy access to the real time data.

Web Report Sample
Successful Implementation: The Box telematics/MeshNetics collaboration yielded a cost-effective,
robust wireless sensor network, providing critical data flow that enables continued structural
integrity assessment of buildings in real-time. This allows proactive, preventive action before any
serious damage occurs.
The wireless SlaveBOX nodes with measurement sensors are placed in and around buildings. They
form an ad-hoc mesh network, using MeshNetics eZeeNet Stack software, that supports ZigBee
network, and transmit data through the GPRS gateway to the monitoring company's server. The
data is then stored in a database and reports are generated. The whole process is completely
automated.
Achieved Benefits
Fast Time-To-Market: Crawford & Company received the working WSN solution in less than four
months. BOX telematics expedited development by tapping into MeshNetics' expertise in ZigBee
network software and hardware design. Thanks to the inherent flexibility of the MeshBean
hardware platform, MeshNetics was able to quickly customize it for this project. The system has
been already deployed at over 10 sites.
Improved Accuracy & Safety: Now data is collected on a regular basis, flowing in real time into
monitoring companies' PCs. This continuous information flow enables enhanced building
condition assessment and early preventive actions.
Cost Savings: The prohibitive cost of labor when the engineers visited sites, along with the manual
data logging, was largely eliminated. The real-time wireless building solution also eliminated the
need to run costly wires in the building-an expense that may exceed $100 per foot.
Improved Operation Efficiency: Claim Investigation time reduced from 6-12 months to only 2
months!
