Hong Kong Police DVIU

HONG KONG POLICE DVIU TRAINING POWERED BY P2 WIRELESS MESH TECHNOLOGY

 This story is featured in Police Report by RTHK. During a walk-through of a unit training drill, viewers can see how the P2 mesh solution works in real-life situation.

  • The Hong Kong Police Force Disaster Victim Identification Unit (DVIU) created a four-hop wireless mesh network for their training operation

  • With just four P2 MeshRanger, the coverage is up to 2km and every corner of the training site is covered

  • Each trainee is equipped with a tablet, so that they are able to move around easily and to carry out victim registration on their server accessing the DVI recording system without delay

  • Without any cable and driven by portable power source, the network is set up within 15 minutes and ready to use, making it convenient to relocate the network to another site easily without compromising the reliability of the network

  • A wireless mesh network of 4 MeshRangers has been deployed to cover the entire disaster site.
After a mass fatality event, the identification of dead bodies is not a quick and easy process, but requires meticulous works closely adhering to international guidelines and legal standards. Proper identification of the deceased is an integral process of disaster rescue not only because it is essential for clearing the disaster sites, but more importantly for it enables victims families to begin the healing process and allows societies to rebuild. In the case of a terrorist attack, the disaster victim identification is also important for identifying possible attackers. Since its establishment in 1975, Hong Kong Police Force Disaster Victim Identification Unit (DVIU) has been standing ready to be deployed to carry out victim identification service, providing support for disaster rescue operations. The DVIU of the Hong Kong Police has been one of the most technologically advanced DVIU in the world, always employing the latest and greatest technologies to improve efficiency. In a recent training operation, DVIU paired their victim identification system with P2 wireless mesh technology for a more efficient and accurate process of their on-site work.

Powered by a portable battery, the MeshRanger is ideal for efficient emergency network construction on disaster sites with power disruption.

 
DVI is a complex process closely associated with scientifically proven technology and visual identification alone is not considered appropriate as a form of identification. Even in situations when the deceased have not been significantly traumatized, erroneous visual recognition is not uncommonly made by distressed family members. To ensure an accurate identification, it is important to involve the comparison of fingerprints, dental records, or DNA samples with those stored in database for a conclusive identification.
 
This is exactly why initial data collection and preliminary registration of dead bodies on site is crucial for the overall process of DVI. To establish a database quickly on disaster sites that are chaotic and sometimes hardly accessible with damaged wiring and power supply, an intuitively-built DVI system and a reliable network connection are necessities. With a stable Wi-Fi network that can be constructed within minutes on the rough disaster scene, a recording system can be established quickly. Hence, team members of the DVI can use a tablet to connect to their system over Wi-Fi to access and update the database on the spot as they are evaluating the site.
 
During the training operation, the Hong Kong Police Force DVIU has successfully created a four-hop wireless mesh network, which covers every corner of the training site with four P2 MeshRanger and every trainee was equipped with a tablet for accessing the DVI recording system. Without any cable and driven by portable power source, the network is set up within 15 minutes and ready to use. With the vast coverage of the network up to 2km, trainees were able to move around easily and to carry out victim registration on their server without delay. Furthermore, it is convenient to relocate the network to another site easily without compromising the reliability of the network. With P2 patented wireless mesh technologies, it is easy to provide a fast and stable backhaul connection that is capable of self-healing even when one of the devices is out of service.

All DVIU members are equipped with a tablet computer to connect to the database over Wi-Fi to update the victim registration record. 
 
With the experience of supporting the disaster rescue training of the DVIU of the Hong Kong Police, P2 is again one step closer to wirelessing the world with no limitation. In the future, P2 will continue to explore more possibilities for its wireless mesh technology and products, striving to widen the scope of its product applications.
