What you are speaking of is image link (Pi-Tac is networking software to give the entire team various bonuses). I'm at work right now, but I believe if you check the gear section, cybereyes have image link already built in (with no additional cost or use of slots). I think cameras also have image link standard, but again you'll have to check the equipment section's description for cameras.
*Edit: For those players at your table that don't have cameras or cybereyes (mages, etc.), they can get contacts, glasses, or goggles and buy image link as a visual modification for one of those, so that they may still see the feeds.*
