The number of crimes is increasing and the proportion of female victims is increasing as well. Whenever a crime occurs, self-defense products are sold rapidly and the revenue earned from selling such products has been reported to be $8.7 billion. But women find difficulty in using self-defense products such as electric shockers or gas guns and can negatively affect the criminal. And those products that show the women’s locations are not very useful as the buttons have to be pressed manually and all they do is show the location of the device. And using security services is too costly for the average person. As a result, we wanted to create a product that would better equip the women to protect themselves, help the women feel safe, and show their families exactly what happened. -Even if the woman does not know she is in danger, her family can prevent further harm.-It is possible to prevent criminals from even approaching the women.-It can also be used by children and the elderly.-It can also be worn as an accessory.-Because pictures and videos are taken, they can serve as evidences.-It will reduce the woman’s fears. -Composed of a sensor, a video camera, and an application that detects criminals for women who have to walk around late at night.-During the day, this device can be used as a necklace or a brooch.-At night, when the woman turns the device and the application on, the sensor and the camera will start running.-It can automatically detect criminals.-When the device detects a criminal, the woman and her family will be notified.-A picture and video will be sent to the woman’s families immediately.-LEDs will be mounted around the device to warn the criminal.
