Telesforo Aviles from Dallas, Texas, pleaded guilty to computer fraud Thursday 

Aviles, who was fired from ADT in April last year, now faces five years in prison  

Acting U.S. Attorney Prerak Shah said Aviles 'intruded on intimate moments'

Aviles was able to access accounts by 'routinely adding his personal email address to customers' 'ADT Pulse' accounts', authorities say

He would then have 'real-time access to the video feeds from their homes' 

In May last year it was reported that ADT was being sued by affected customers
