You will not need a filter to incorporate video from a camera into your satellite system unless you are using an Off-Air antenna or Cable Television (CATV) in your system. A Channel Plus Modulator and two V902 Diplexers will be required for a basic single receiver system. If a Multi-switch is used to distribute the down-feed from your satellite dish to multiple satellite receivers, you will need one or two diplexers per receiver depending on if the multi-switch has an antenna/auxiliary input connection. You may also need a splitter depending on the number of satellite receivers in your system.
