I have ordered one of these wifi cams however I am curious if anyone may have any input to offer on the security of the device as it relates to the network. My understanding is that they are set up through the Yi Home app, and that the camera is connecting outside the local network to the mobile application through the Yi servers. The camera is also able to be accessed from outside the local network via the app without any port forwarding being required on the local router. Personally I would prefer the ability to have the camera only be accessed on the local network through a VPN rather than having it exposed to the WAN. Does this seem like there may be reason for concern about possible intrusion into the camera since there is no way to block it from being accessed from outside the network?
