Camera and audio requirements

The module can be enabled on any camera that has a microphone; however, it is not recommended in noisy outdoor locations such as underground stations, railway terminals, etc.

Computational complexity

The computational complexity of the module estimates "Low"; the exact numbers may vary with video resolution and CPU parameters.
