It happens that Peter Parry formulated :
You usually have
only a very short time (30 sec or so) to press the router WPS button
on the router after starting WPS on the camera. (WPS does not work
with WEP).

The cam speaks, and tell you what it is doing, which is how you tell
whether you have it set as an AP or if it is trying WPS. Once set to
WPS, it speaks every few minutes that it is trying to connect to
Smartlink.
