Safe City Platform

The NEW Safe City Platform connects alerts from the BlackBox Digital Witness App and other devices, such as video doorbells, IP cameras, and other alarm systems. Each alert is classified as a non- emergency or emergency alert. Emergency alerts are sent to participating Law Enforcement, 911/PSAPs, and local Neighborhood Watch Captains. Non-emergency alerts are sent to just the Neighborhood Watch Captains to review and compare with other reports, or share with the community.

The BlackBox Digital Witness mobile app is powered by BlackBox and is available from your App Store. Search for BlackBox Digital Witness to install it.
