To get started, is the alarm panel already set up with the Wi-Fi network using a manual setup, such as what is detailed in this video? https://www.youtube.com/watch?v=dQqvPN36NAk
There's no WPS support on the FiOS routers (for a good reason too), but you should still be able to get the camera manually connected to the network. If you could give a camera model number we'll see if we can help. Most cameras that I've seen have an Ethernet port, which is often used to connect the camera up with a wired connection, or to access the camera so that wireless can be configured manually instead of via WPS.
