response to data provided by the monitoring component and/or the sensor. ### Claim 8 (depends on 1) The security system of claim 1, wherein the monitoring component does not comprise a display stand. ### Claim 9 (depends on 1) The security system of claim 1, wherein the monitoring component and/or any one of the plurality of sensors are not configured to initiate an alarm signal when the proximity between the monitoring component and the sensor is greater than the predetermined distance. ### Claim 10 (depends on 1) The security system of claim 1, wherein each of the plurality of sensors is configured to removably engage a respective input port of the item to be in electrical communication therewith, and wherein any one of the plurality of sensors is configured to initiate an alarm signal in response to the sensor being removed from the input port of the item. ### Claim 11 (depends on 1) The security system of claim 1, wherein the monitoring component and the plurality of sensors are configured to communicate with one another to determine a proximity of each of the sensors relative to the monitoring component. ### Claim 12 (depends on 1) The security system of claim 1, wherein the alarm signal is an audible and/or a visible signal. ### Claim 13 (depends on 1) The security system of claim 1, wherein the at least one monitoring component is configured to paired to
