Assuming there's 120VAC power at the shed, does that 200 feet between house and shed have clear LOS (Line Of Sight) ?
I've installed over a dozen Ubiquiti Layer 2 Transparent Bridges in the last several years but the Nanostations and Loco's of both 2.4 and 5GHz flavor have been hard to get or VERY expensive this past year or so. About the only one is stock right now is this for $60, quite overkill for your distance but you can dial back the transmit power==>>
Ubiquiti airMAX LiteBeam Gen 2 5AC 5GHz 23dBi CPE US
I hesitate to recommend a pair of the
TP-LINK CPE210 radios even though I put one in a week ago and it's working great BUT....all my Ubiquiti installs have been running with no hiccups for over 8 years now...time will tell about the TP-LINK wireless bridge.
If you set up BOTH radios as a Layer 2 Transparent Bridge like this it'll work. Assign unique static IP's to both radios and the cam in the same subnet as your router's LAN but outside of its DHCP pool ==>>
airMAX - Guide to Configure a Point-to-Point Link (Layer 2, Transparent Bridge)
If set up correctly the Layer 2 Transp. Bridge will be like a CAT-5e cable, but without the distance limitations, will be a dielectric media that won't attract or conduct ESD / lightning damage but of course, cannot carry POE voltage.
Here's the schema I've used the last several years. The above Litebeams are different as far as configuration terms but the instruction above to the Ubiquiti airMAC Guide will make that distinction between "AC" devices (like the Litebeam above) and "M" devices (the type in my image below) when configuring.
