No. Purchases of the PSVR 2 preorder come with everything you need (minus a PS5 and games of course). The PSVR 2 Sense Controllers are included in the box along with the headset, so you've no pricey extras required to play from day one.
That goes some way to explaining how expensive the PSVR 2 is compared to the first model released years ago. In many cases, you had to buy the PS Move controllers and indeed the required camera separately which drove up the price considerably. No such issues this time as you don't need a camera at all this time.
