There are many companies working on this type of technology at the moment. We made ours in 2018, and Chad visited my house in January 2019 to film most of this. We didn't post it for various reasons, but decided now might be a good time. The fidelity of the inference is a function of how you train it.... so obviously the more data points you provide, the better it will perform. This particular type of machine learning is known as object detection, with the computation being performed by a deep neural network "on the edge". The video stream is processed locally and no internet is needed to find the object in real time. If you're working on something similar or could use this technology in your systems and would like to collaborate....

Do me a favor and PLEASE CONSIDER SHARING THIS VIDEO. I'm a bit worried it won't be distributed due to images in the video and the topic in general.... but I believe this is a positive thing and it's something people on both sides of the gun debate can get behind. I've been talking to people about this type of technology and in an upcoming video I will explain how this is simply one component in a much larger suite of tools which can be used. Are there flaws in this method? Absolutely. Is it possible to spoof a system like this? Yes... this could be easily tricked.... but would be perps would have to take the time to worry about it focus on tricking it. I personally think the main benefit is providing real time situational awareness. Another limitation is that it would identify toy guns as real guns and send a notification to authorities. The purpose of this video is to start the discussion because systems like this are frankly already here and in use. We don't claim to have all the answers, but we decided to use our engineering skills to try to make a positive step. We've found support amongst both sides of the gun debate, and in today's political climate that alone feels like a step in the right direction. If you'd like to reach out, we can be reached through a contact form here: www.lantern.systems/gun-detector

@MWall711 I just saw this so sorry for the late reply. If you really think that the Navy would obliterate an entire US community with cruise missiles or that the Army would roll tanks and armored vehicles down the streets in the US to destroy everything in their paths why would you ever surrender your rights to such an authoritarian force? When you purchase the ticket for that flight you accept a contract that states that you and whatever you have with you are subject to search. Whenever you enter into an amusement park, zoo, stadium, etc you accept the terms that go with admission to include being subject to being searched, to include any property you have with you. You waive your 4th Amendment rights when you accept the terms to fly on a plane. The 4th Amendment does not restrain private businesses and if it did, you still waive your rights when you accept the terms to enter their establishments. Only a fool believes that any part of the Bill of Rights is obsolete.

The problem I could see with this is unconscious racial bias, most of the b roll I see here is lighter skin individuals, which makes sense if he’s using movie footage and gun store individuals. A lot of the times software developers don’t realize they haven’t used sufficient amount of darker skin tones, this is why hand motion detectors or facial recognition sometimes fails for darker people because the AI doesn’t have an equal ratio of information to learn from for darker tones.

Two ideas: User interface design & training the AI. User interface: never contrast red and green because a very large percentage of the population is red-green color blind. Furthermore, because this particular distinction is extremely important, use multiple visual indicators to convey information. For example, in addition to the different color tags, use different geometric tags: maybe put a hexagon around a suspected gun and a rectangle around phones. Training the AI: have users submit photos and videos. Provide instructions of the format requirements and how the user must tag the gun, phone, or other object. Most of the submissions should be mundane, especially in the beginning. Then challenge the users to submit videos that will create a false positive or a false negative. If a video creates an incorrect response, use it to improve the AI.

It's quite simple... the public do not need to carry guns. Sure, be a member of a gun club and use the gun at that place and leave it at that place after use. But under no circumstances, do members of public need to have guns in public. If gun store owners are the only people allowed to purchase guns then the public can use them at the gun range. It's as simple as that. Guns cause violence. They give power to the weak minded. Take that power away from them.

From engineering point, it is a very good subject and an entertaining video. Thank you. But, the solution ultimately relies on solving the gun problem by putting more guns into the equation (i mean in the hands of the good guy against the bad guys). You can put an automated gun platform in every classroom with a detection system like this and it still will not solve it. Good video though... Really enjoyed it

It looks like a majority of the pictures used to train the model are white people holding guns. So what if the shooter is black or wearing black gloves. Additionally security camera have a harder time with dark skin cause of the lack of dynamic range. Those two factor compound, trained with images of mostly white people and lack of dynamic range in imagery. Which is what’s caused the perception of racism in ML. So how does the system do if the person holding the gun isn’t white? (Granted most mass shooters are white but that’s not the point) How does this affect the models precision and recall? I’m thinking that the lack of contrast making it difficult to see a hand on the gun may be an issue.

Good topic with strategy! I agree, that we need to have a gun for protection as it comes under the second amendment although, misusing the gun via illegal activity is not acceptable. Nevertheless, the problem of the gun isn’t as simple to be eradicated through a gun detector, while technology & engineering should not play an important part in things that can take a life. Therefore, I disagree with the software gun detector strategy which does invade the privacy. For the sake of debate(not a debate fan), the first question arises is how are we slacking behind as a human to input the correct info into the public database? Does the police department have the info into mental health, drugs or criminal history? If they do all the information for an individual for the particular local region then how are the guns getting approved? The responsibility we are given in the community to the highly educated or skilled police officers isn’t only to have the name & tag on it but to be able to find the solution without depending on the technology & engineering. At the end of the day, if an innocent person dies due to gun violence, not because of her mistake but the one who approved him/her gun after knowing the fact through the background check than who is liable? The gun business owner, police department, gun detector software or the criminal in lose? The more we stop emphasizing building or depending on the technology and start taking responsibility in the top management the lesser crime will take place. I think we all know our rightful amendment but to follow through the safe way to protection while everyone should be accountable to their problems within them could lead to less gun violence stories. Aren’t we all are liable? Although, instead of debate we should consider the facts rather than the technologies protocol.

Guns don't kill people. People kill people. By making stricter gun laws, you are only HELPING criminals and illegal gun users, because they could not care less about your laws. You are, however, taking guns out of responsible people's hands, that could have defended themselves, their families and your family.

As someone who's a LEGAL owner, and LEGAL carryer, give me one good reason why I should support something like this. Reassure me that it won't be used where it shouldn't be. That it won't be used to target people like me. That it won't be used to SUPPRESS people like me. This is DANGEROUS.

Honestly the technology they made is useless because all it says is there is a gun out. Should a situation like this exist it's probably already too late. It's an ai that can detect a gun but that doesn't mean anything unless guns were illegal or in a place they aren't legally allowed to be.

In conjunction with an automated lockdown system, this could be quite useful. Not to lock down potential victims, but rather trap an active shooter allowing potential victims to escape.

Guns are only divisive to the nutjob Leftists. Let us remember how Guns save more lives in the civilized world than they take lives. We owe our lives to Guns and without the amazing gun/rifle, America would not exist. That is why the nutJob Leftists want to steal our Guns. We should go back to the Constitution and make the statement, "Shall not be infringed upon" mean exactly that. Everyone should have the right to keep and bear arms. Yep, no exceptions.

See if you could get a computer with better processing power and a camera with a higher resolution to see if that would change its ability to recognize a firearm from longer distances. One more suggestion I think if the program see's anything resembling a firearm it should Zoom in depending on its conference level to determine if it's a firearm or not . Hope you see this comment and I would like to know what you think about it.

It's also interesting to note that the camera system does not recognize when the handgun's slide is not racked. This is a problem.

A gun detector is worthless unless it violates people’s privacy. If someone is gonna do something bad with a gun, they’re gonna keep it out of public view until the last minute... if they even show it at all (keep it hidden under a napkin, in some flowers, in a box, in the trunk of your car a la DC Sniper Mohammad). Freedom is deadly. Gun deaths are inevitable in a free society, suck it up. Freedom isn’t free. Freedom means lots of dead children. But it’s worth it, and fortunately humans are not an endangered species. Quite the opposite... we need some culling.

My first thought is to really use this technology, you would need to make sure the camera system is of the highest quality. I can imagine a lot of false positives or missed firearms because of low video quality and bad lighting. Also curious about how this would work with pistols that are not the standard silver or black. SCCY had various colored pistols if memory serves me. Very interesting approach. I wonder if this will see the light of day or will "they" push more for the x-ray skip due process version instead.

Destin. As smart as you are, the stand you take on this surprises me. I can tell you a solution to Americas problem with fatal shootings. Get rid of the guns! The solution is not to keep the guns and then invade peoples privacy by using different technologies. Almost every other country recognizes this, why don't you? Your will to keep playing with guns isn't more important then all the lives taken by them. You do understand numbers, so check some statistics on America and gun violence compared to other country's and let me know if you come up with another answer of the problem then the easy access to guns in the US. Otherwise, you taught me loads of good stuff, you are doing a amazing job on this channel.

It's kinda worrying on how everyone takes what you say wrong right away in the replay chat even though you say right away you are not looking for a solution and only a key component to being at least slightly fixed, yet everyone in the chat expected you to come up with a perfect solution for everything. Anyways, great video! Really enjoyed it!
