@Lorih,

Its impossible to know what the goal is of someone doing something like this. At a base level, them gaining access to your account will give them the same control that you have over the recordings and scheduling of devices. 

Usually, an account is broken into just so that the hacker can verify their usernames and password, to see if they could work on other services with the same credentials. Either way, it is recommended that you enable two factor authentication to limit the potential of third party intrusions
