Hello :) 

I've been trying to access my 3 Tapo C200 and 1 C310 cameras on my cottage through the internet but to no avail.

These are great little cameras, but if someone cuts the wires, steals them or destroys them, I have no means to know who did it, so I thought of connecting them to my Synology NAS's Surveillance Station, which is in my main house, and keep the footage there for redundancy.

I've tried accessing one camera using DDNS so I can always connect to them using one address, but it's not working. Are there any workarounds? 

I don't have a PC at the cottage at the moment, only when I take my laptop.
 

There is a possibility to grab a Raspberry Pi and store the footage there and back them up to the NAS, but since I don't own one, I would like to try and solve this problem without spending more money :) 

Thank you in advance, I hope I made myself clear, my english isn't the best, sorry! :)
