Why does Xfinity not provide a way for home security subscribers to password protect public access to their video cameras?

@noproblemo123 -

While we don't offer a password protection, you can set up Parental Controls on each of your X1 boxes to accomplish something similar.  Once set up, a 4-digit pin will be needed before being able to see camera feeds.

To do this, go to your X1 box and press the Xfinity Button on your remote to bring up the main menu.  Choose Settings (far right icon) --> Parental Controls. 

If you don't already have them set up, a Parental Controls setup screen will appear.  If all you are attempting to do is block access to your cameras, you can choose "Skip" at the bottom.  If you do already have Parental controls set up, enter your PIN.  You'll now be taken to the main Parental Controls menu.

Choose "Application Locks."  If you didn't have a PIN set up yet, you'll be prompted to create one now.

Hold the "Page Down" button down on your remote to scroll toward the bottom of the list of apps.  Once there, use the arrow keys to highlight "Xfinity Home" and press the OK button to lock the app.  You can now press Exit to go back to live TV.

Now when you go to view your cameras or launch the Xfinity Home app, you'll be prompted to enter the PIN.

I hope this helps!
