Weapons Detection

 Evolv's systems use a combination of sensors, algorithms, and artificial intelligence to detect weapons. The sensors include millimeter-wave radar (similar to airport security scanners) and thermal imaging cameras, which can detect the shape and temperature of objects. The algorithms analyze the sensor data to identify potential weapons based on their size, shape, and other characteristics. The artificial intelligence component uses machine learning to constantly improve the accuracy of the detection system. Additionally, Evolv's technology is designed with privacy in mind, and only alerts security personnel if a potential weapon is detected – it does not store or transmit any personal data. 

 ZeroEyes uses artificial intelligence, machine learning, and computer vision technologies to detect guns in real-time video footage. The system analyzes video feeds from security cameras and identifies characteristics of a gun, such as its shape, size, and color, in order to immediately alert security personnel to potential threats. The software also takes into account the context of the situation, such as the presence of law enforcement personnel, and uses that information to make more accurate predictions.
