Can I have 2 internet providers in my network?

Here's my current setup:

ISP 1 ----- router 1 -------- access point ------ router 2

Router 1 is in my house

Router 2 is in my office

I need to access the office computers from my home.

I need a new internet with static IP in my office for my surveillance cameras. So I'm planning to connect it to router 2.

Is this possible?
