@jeuts310,

I will look into this further, how,ever this is almost always a false positive from your home security and IoT protection. We have had users, with cameras already set up that will receive this notification when the firmware is updated. In reality, the system is just blocking the video stream of the camera. 

Until I get back to you, I would recommend checking with the support and community over at Xfinity. If your husband is still concerned with a security risk, the cameras can always be factory reset back to normal for peace of mind.
