If you want to delete a video from your Xfinity Home Security account, there are a few different ways to go about it. The first way is to go to the video that you want to delete and click on the three lines in the top left corner of the screen. From here, you can select “Delete Video” from the menu that pops up. If you want to delete multiple videos at once, you can head over to the “My Videos” section of your account and select all of the videos that you want to delete. Then, click on the three lines in the top left corner of each video and select “Delete Video.” Finally, if you just want to remove a specific video from your account but don’t want it deleted permanently, you can head over to Xfinity Home Security and click on “History” in the upper right corner of the screen. From here, you can select which days or hours of footage are visible in your history and then choose “Remove Video.” ..
