14. A Computer Assisted Dispatch (CAD) system, comprising: a network interface communicatively coupled to a network; a processor communicatively coupled to the network interface; memory comprising instructions that, when executed, cause the processor to: capture keywords from an incident report related to an incident of interest at a first time period; create an incident-specific dictionary for the incident of interest based on the captured keywords; provide, via the network interface, the incident-specific dictionary from the first time period to at least one video camera capturing video or to a back-end server communicatively coupled to the at least one video camera based on a plurality of factors; capture updated keywords as the incident of interest unfolds at a second time period; update the incident-specific dictionary with the updated keywords; and provide the updated incident-specific dictionary to another video camera or to a back-end server communicatively coupled to the another video camera based on the plurality of factors.

The CAD system of claim 14 , wherein the instructions that, when executed, further cause the processor to: receive an alert from one of a plurality of video cameras or associated back-end server that a keyword from the incident-specific dictionary or the updated incident-specific dictionary has been detected in captured video, wherein the alert is generated based on video analytics using the incident-specific dictionary.
