With the accelerated rate at which technology is progressing in this world, it is becoming increasingly more difficult to stay in the shadows, so to speak. It is even harder when billion-dollar companies have access to your secure files and documents. So, that leads to the question of whether or not that is an issue with these types of security camera systems. Here is the good news; the security companies in the world (which includes Protect America, Vivint, ADT, and Frontpoint) do not have access to the footage and files of your camera.
However, if these same companies happen to offer a video monitoring service then yes, they will have access. But, given that they are security companies, they are out to increase your security.
