During an emergency every second counts. That is the premise behind CLICK. The iOS app is the companion Mobile Application to the CLICK software. CLICK (Active Lockdown and Emergency Response Technology) can be a cloud based or local software solution that empowers its user by allowing them to initiate a lockdown from any authorized and configured smart phone, tablet, or desktop PC. This significantly reduces the amount of time between the recognition of a threat and the initiation of a school lockdown. The CLICK System integrates with existing (or future) electronic door locks and surveillance cameras, allows its user to send their current status with location, and allows administrators to provide instructions to the user during a lockdown.
