Technology is being tested to help fight crime in a neighborhood that is being victimized by gun violence in San Jose. The “gunshot detection technology” is designed to provide real-time notification to police when gunfire is detected. The Cadillac-Winchester neighborhood near the San Jose Campbell border has historically been impacted by gun violence. Residents regularly report gunfire, but now police have a new tool to help trace the source of that gunfire. A 6-month pilot program is underway to test V-5 systems’ on-sound gunshot detection system.
