Abstract: Disclosed implementations provide a system of sensing modules that can operate in conjunction with a Software as a Service (SaaS) backend to detect and alert of various threats. The sensing modules can be installed at fixed locations or can be mobile. All sensing and detection processing can be accomplished by the sensing module or by several sensing modules cooperating on a mesh network or other network communication architecture. Privacy is preserved because all raw sensor data collected for analysis is processed locally at the sensing module(s) and deleted immediately following the completion of analysis. Accordingly, raw sensor data is inaccessible outside of the sensing module(s) which can be secured through hardware and software security techniques. An app can include an alert button and the ability to live stream video images. The sensors can include AI agents and the system can include a drone dispatch module.
