Again, we see the human factor as the biggest vulnerability. Integrity and control are keywords we often use, and want to experience when we talk about security. One question to ask yourself is "who has access to sensitive data?" and limit it, as well as having a high level of protection in the form of encryption and strong passwords for access. Then it is downright a bad idea to set up other cameras in your home that an external actor has full access to, even as stupid as just them. And not you as a paying customer.
May it happen that we at IT Does Matter can go by the epithet "foil hat". But having data locally, where only you have access and 100% control is a good idea that goes a long way in protecting yourself against intrusions and stolen data. That's why our solutions are 100% local in your home. And only you have access and 100% control.
