Requests between the camera, mobile phones, and server use a two-way mutual authentication process to ensure that the user's personal information is not stolen. Each device has its own secret key and certificate to authenticate with the server.
User information and video streams both have professional-grade encryption protocols to ensure the security.
Using a P2P encryption channel for video transmission ensures that only the end user can view the video content. Any interception of mid-transmission information will only result in invalid encrypted data.
You can set passwords for each camera to ensure mobile client video privacy.
