A signal detection system comprising: a processor; a data processing module executed by the processor to, obtain data from one or more data sources, wherein the data sources include data in different formats and at least one format of data is video and audio, wherein the signal detection system is communicatively coupled to the data sources through a network; and standardize the data, based on at least one template, to obtain standardized data, wherein the standardized data have data properties depicting a format and a size of the standardized data and the at least one template is determined based on at least one recommendation data and data properties of the data, wherein the at least one template having a predefined set of rules to standardize at least video and audio to text files; and an analysis module executed by the processor to, determine one or more detection rules based on the at least one of recommendation data and the data properties of the standardized data, wherein the recommendation data includes recommendations, received from a user, indicating a user selection for a detection rule from amongst the one or more detection rules; and detecting at least one signal present in the standardized data based on the one or more detection rules by processing the standardized data to obtain a primary signal, removing the standardized data for which the primary signal is obtained and further identifying a secondary signal from the remaining standardized data. a processor; a data processing module executed by the processor to, obtain data from one or more data sources, wherein the data sources include data in different formats and at least one format of data is video and audio, wherein the signal detection system is communicatively coupled to the data sources through a network; and standardize the data, based on at least one template, to obtain standardized data, wherein the standardized data have data properties depicting a format and a size of the standardized data and the at least one template is determined based on at least one recommendation data and data properties of the data, wherein the at least one template having a predefined set of rules to standardize at least video and audio to text files; and obtain data from one or more data sources, wherein the data sources include data in different formats and at least one format of data is video and audio, wherein the signal detection system is communicatively coupled to the data sources through a network; and standardize the data, based on at least one template, to obtain standardized data, wherein the standardized data have data properties depicting a format and a size of the standardized data and the at least one template is determined based on at least one recommendation data and data properties of the data, wherein the at least one template having a predefined set of rules to standardize at least video and audio to text files; and an analysis module executed by the processor to, determine one or more detection rules based on the at least one of recommendation data and the data properties of the standardized data, wherein the recommendation data includes recommendations, received from a user, indicating a user selection for a detection rule from amongst the one or more detection rules; and detecting at least one signal present in the standardized data based on the one or more detection rules by processing the standardized data to obtain a primary signal, removing the standardized data for which the primary signal is obtained and further identifying a secondary signal from the remaining standardized data. determine one or more detection rules based on the at least one of recommendation data and the data properties of the standardized data, wherein the recommendation data includes recommendations, received from a user, indicating a user selection for a detection rule from amongst the one or more detection rules; and detecting at least one signal present in the standardized data based on the one or more detection rules by processing the standardized data to obtain a primary signal, removing the standardized data for which the primary signal is obtained and further identifying a secondary signal from the remaining standardized data.
