I have an office and 2 other buildings that are about 1500 feet apart. I have Internet at the office and a Ubiquiti Rocket radio/antenna connected to the router transmitting internet out to the buildings which are equipped with a nanostation m5 and a router at each building. What that means is that all 3 buildings are on the same network LAN. That all works well. Now I want to set up 2 cameras at the office and 1 each at the 2 buildings. The NVR will be located at the office and hooking up the 2 office cameras is straight forward. Here is the question......can a camera hooked up at each building and plugged into the router at each building be accessible to the office NVR? Basically I would be sending cam traffic from those 2 locations through the routers......or how can it be done?
