3.2.5 E-Map Monitor
E-Map monitor is a function that alerts users whenever there is an event
triggered (e.g. motion detected) from a camera with a geographical
perspective. With this function, users can quickly identify which camera has
detected an unusual event and where this event is happening. This function
works by incorporating the event detection function as well as the recording
function, which, as a result, helps users take all the necessary actions when
an unusual event occurs.
