Applications in Search & Rescue

Applications of the Sentry MDU System
The Sentry MDU System offers special benefits to Search & Rescue Teams for both urban and rural locations. Depending on the type of Search & Rescue activity it may be staffed by professional SAR personnel only or a combination of professionals and volunteers.

By converting an everyday cell phone into a versatile communication, video recording and GPS tracking device, the Sentry MDU System can become a valuable tool for all that participate in SAR activities. The GPS location of each Team Member can be monitored in real-time or video can be recorded (Body Camera) or transmitted “live” to the SAR Command Center for review. The location of each Member is displayed in real-time GPS “tracking” on each members mobile device such that all search personnel will know the location of all other personnel.

Situations where the Sentry MDU System can be of value to Search & Rescue Teams:
  • Tracking the location of all Searchers
    With a GPS enabled device, the SAR Command Center will know where all personnel are located. Resources can more easily be redeployed as necessary.

  • Verification of Grid Search Areas
    In any Search & Rescue activity the most critical factor is the efficient use of personnel in covering a specific area (good grid coverage). Since the Sentry MDU App is installed on a cell phone carried by the search members (almost everyone has one) and the “GPS tracks” will be displayed in real-time, the grid coverage can be easily determined from those at the Command Center.

  • Damage assessment transmitted via real-time video
    Using the Sentry MDU System, a SAR Member is able to record and transmit real-time video back to the Command Center. With the corresponding GPS coordinates and a visual review of the situation, it will allow the SAR Command Center to more easily direct Medical Personnel or other resources to the exact location needed.

  • Using the Sentry MDU System as a field measurement tool
    One of the lesser known features of the Sentry MDU App is the ability of a User to measure distances on a satellite map. For example, if a SAR Team wanted to spot a landing zone for a helicopter the App provides a way to draw on a satellite image overlay map and then measure distances between points. This “map drawing” can then be sent to the SAR Command Center for processing.

  • Sentry MDU System used as Dash cameras for SAR Patrol Vehicles
    The Sentry MDU enabled cell phone can be mounted on ANY vehicle windshield and it immediately becomes a “dash camera”. Generally, it is rare for SAR vehicles (or private vehicles brought by SAR Members) to have this capability. The Sentry MDU System now makes this possible. If desired, live video can be transmitted to the Command Center.

Mounting and/or wearing the cell phone
Since the Sentry MDU System starts with a cell phone it is simply a matter of deciding how a User wants to mount or wear the device. Cell phones come in all sizes. Some will fit easily in a pocket and some will not. Below we offer several suggestions. The one that works best for you will generally come down to personal choice.


Possible ways to mount and wear the cell phone
  • Easiest - Simply slip the phone into the front pocket of your uniform
  • Use one of the many “clip” type phone cases
  • Alter the front pocket of your uniform to accommodate the phone (more hidden solution). Have a tailor cut a hole in the front of the pocket (for camera lense), use a button hole stitch to make it look “finished” and you are ready to go.
  • Design a cloth phone pouch that will attach to the uniform by safety pins. Then you can put it anywhere on the uniform you want. Make sure the phone pouch has a hole in the front for the camera lense to show through.
  • Come up with other options on your own. It is not rocket science. Come up with a good idea, patent it, and make a million bucks.
