Why not use a powerline adapter and send the data over the electric line? That is a much better choice than a wifi camera.
Wifi is problematic for surveillance cameras because they are always streaming and passing data. And the data demands go up with motion and then you lose signal. A lost packet and it has to resend. It can bring the whole network down if trying to use it through a wifi router. And then you are far enough away that you would not have full signal, and it will slow your whole system down.
Unlike Netflix and other streaming services that buffer a movie, these cameras do not buffer up part of the video, so drop outs are frequent. You would be amazed how much streaming services buffer - don't believe me, start watching something and unplug your router and watch how much longer you can watch NetFlix before it freezes. Now do the same with a wifi camera and it is fairly instantaneous (within the latency of the stream itself)...
Most consumer grade wifi routers are not designed to pass the constant video stream data of cameras, and since they do not buffer, you get these issues.
I wouldn't recommend an indoor camera because even if the porch is covered, unless the porch is enclosed, the camera will still be susceptible to condensation with temp changes. Maybe the camera last 2 years, maybe 10, maybe 6 months.
