Assigning static IP to every device?

Hello all,

This might seem very dumb to some of you but here goes.

I am helping a friend setup a business. The ISP provided me with all the info in regards to the static IP they set, the gateway, DNS server(s) and subnet mask. I setup the router using this info. Plugged in a managed network switch which is running a few devices. Now do I have to configure every single device on the network with a static IP since the ISP provided one or does the switch automatically set IPs to the devices?

I am also setting up a NVR and the cameras do not show up, why is this the case? I have set up port forwarding and got nothing so far.

Any help? Sorry this is a big all over the place.

Thank you all.
