Pressing the panic button via the keypad not setting siren off on Camera’s

Hi there, Those who have the Alarm system will know there’s 3 buttons. Fire, panic and Medical. Now my question is around the panic button. When pressing this either by the App(at the top right) or by holding down the panic button on the Keypad. this only sets off the siren box and the keypad siren. I’ve got 4 other devices that have built in sirens but these don’t alarm for some reason? Surely panic alarm should set off everything with a speaker? Surely that should of been thought of in the idea of a panic button right?
