CHIEF-Gunfire Detector

Indoor Gunfire Detector

What's the big idea?

The big idea is to create and deploy indoor gunfire locators/detectors. The system would use innovative technology to discriminate gunfire and automatically notify municipalities that an event has occurred. We want to reduce the amount of time it takes to alert the authorities in order to reduce their response time. This will save lives and hopefully act as a deterrence to future gunman. The technology is already there to detect gunfire, but the current systems cannot detect the gunshots indoors which is where our system will excel.

Describe the nearest player in your field.

The nearest player in our field is ShotSpotter. Their website states,“SST delivers the world’s most powerful, most scalable and most trusted gunshot detection solutions to local, state and federal agencies, governments and businesses all over the world.”

How are you different from that player?

Our idea is innovative as said before since SST does not have a system that can be used indoors and nor can it detect gunshots indoors. SST focuses on acoustical sensors. CHIEF will use an array of sensors to further reduce false positives and increase reliability, while remaining affordable.

How does this idea scale into a big business?

Currently the amount of buildings in the world is unknown. However, there are more than 136,270 schools in America to start with. CHIEF can be installed in a variety of buildings such as movie theaters as well. In the long run we hope to develop other devices as well.

Why are you the one to run with this idea?

I have been working on project CHIEF since December. I have a dedicated team of professionals waiting on standby and others who started already developing the device. CHIEF is not an idea, it is a passion geared towards saving lives, which is what I live for.

What is a $5,000 experiment you can do to move your idea forward?

The first experiment will consist of buying additional hardware (acoustical and optical sensors)and software (opensource code)in order to complete the first prototype. From there we will have rigorous testing to do to insure reliability before commercialization.

    This could make a lot of people feel a whole lot safer! We need something like this implemented everywhere!

    Thank you Kyler. We appreciate your feedback.

    I personally don’t believe that a system like this is going to save lives, and it might increase police reaction times slightly.  That being said, I think there is a huge money making opportunity here.  With all the lobbying that takes place for gun safety, getting a regulation that requires this type of technology in buildings (much like fire alarms), could make this very big business.  Good luck!

    I like it. What is your progress?

    Hello Kevin and Vanessa! Thanks for your interests. Progress thus far is stuck at the electrical engineering phase. I am trying to get the GVSU Engineering department to sponsor me on this project even though I am a biology major.
