Hi everyone,

I am struggling to broadcast a wireless network approximately 300-350 feet away from my home in order to connect a wireless surveillance camera to an NVR. Here's a good view of the area for reference:

I'm looking to have two wireless networks; one is my existing SSID that is used within my house but the other would be a separate one specific just to that wireless camera. Ideally, it'd be great to not broadcast the camera-only network. 

Previously, I was using the TP-Link N300 and, while it worked, it was not consistently getting bandwidth to/from that bottom location. On top of that, if I connected to the network from my phone, it wouldn't even get any internet so it was really strange. I suspect that I customized the settings too much. I would frequently need to either reboot the system from the local IP or physically unplug and replug the PoE injector. 

More recently, I got my hands on the TP-Link EAP225-Outdoor. I have it set up in the Omada app for iOS and it shows up under the Standalone APs section of the app. There doesn't seem to be too much customization but it seems to work a bit more reliably than the N300 did. However, I have to have the resolution, bitrate and frames per section very heavily downscaled. Plus, it seems to still have poor coverage with frequent outages, especially lately. As I'm upgrading my camera system, I'm not able to get a new model camera to connect to either my home network or the camera-only one.

The neighbor that lives at the house in the middle of the photo is more than willing to let me put another device on her roof or an eave, but I'm not sure which product to get here and how to configure it so it can work off the existing network I'm broadcasting without needing to be plugged into etherhet. 

My questions:

• Are either of these TP-Link products wrong for my use case?
• Should I go back to the N300 with certain settings?
• Is there anything I need to change with the EAP225-Outdoor (though the Omada app doesn't give many options for settings unless there's another UI to get into the device)?
• Should I buy another EAP225-Outdoor (or N300) to extend the existing device that's wired into my network (at the neighbor's house in the middle of the screenshot above)? Or can I use both devices together somehow?
• Any other suggestions for how to accomplish this?
