Automatic profiling of video analytics applications

A system for deploying a video analytics system, comprising:

• a hardware processor;
• and
• a memory that stores a computer program, which, when executed by the hardware processor, causes the hardware processor to:
• determine one or more applications for a security system in an environment, including one or more constraints, and to profile each functional module in a directed graph representation of the one or more applications to generate one or more configurations for each functional module, where the nodes of each graph representation represent functional modules of the respective application, with repeated module configurations being skipped;
• estimate resource usage for each of the one or more applications using the one or more configurations of each functional module and the one or more constraints;
• deploy the one or more applications in the environment;
• and
• perform a security action in the environment using the one or more applications.
