The security cameras in our smart homes from well-known smart home brands like Amazon and Google might not just be watching over our pets. According to an article in The Verge, they can also aid law enforcement in their investigations of crimes, but only if we do not mind the police viewing our footage without a warrant.
That implies that the police can access our private information without first presenting proof that an emergency situation exists. Police will probably only make use of this access for lawful objectives, such as preventing crime or attempting to locate a missing person in need of assistance. However, it does raise some issues regarding what may transpire when this technology becomes even more widely used and available.
What if, for instance, this access is utilized to locate and detain activists or protestors who have not breached any laws? Citizens may only exercise caution when shopping, be aware that their smart device may record personal information, and, if possible, enable end-to-end encryption.
If you have any questions about how to secure your smart home, do not hesitate to contact me.
