In certain situations, calling 911 may put you in higher risk. For example, a passenger in a rideshare car who feels threatened may not want to attract the driver’s attention with a voice call. The same goes for the victim in a domestic abuse situation. In these scenarios, contacting law enforcement silently is crucial to gaining safety. We here at Zco Corporation have developed a solution that will allow you to send a silent alert to law enforcement using Maphub, a map based social network for the community. Law enforcement uses PublicEye, another app developed by Zco, to receive and respond to the silent alert. This short video shows our solution.
