Sorry I don't understand much about surveillance systems, I am looking for a NVR 24hr recording that is for an off-grid setup/location, and only gets notifications when I am physically there, and when I leave, I don't need to get any notifications. Is it possible to have NVR + a router with Wi-Fi to get notifications only when I'm in that area? If its something that's not possible or I'm not explaining it correctly, can someone briefly explain more how it works or alternative ideas/options. Thanks
