Can a 2nd router be used to secure WiFi cameras against the other router that the computers are hooked into?

I'm paranoid about a Chinese camera company YI Technology which sells feature laden WiFI indoor 1080 Dome cameras on Amazon which requires their "YI Home App" on my Android smart phone which controls the pan/tilt and features of the cameras. ('Works quite well, actually.) Therefore this company in China has my SSID and PW to my network right now. I'm able to watch the cameras "Live" from my cell phone. They've been around for at least 3 years, and get good reviews from CNet, Amazon reviewers, and a couple other tech sites, but I'm still paranoid.

QUESTION: Can I buy a 2nd router and pair up these WiFi cameras to my smart phone on the new separate router, wherein the "camera router" does not have access to the traffic running through the router that my computers and other devices are connected to, and if so would the camera router be the router connected directly to the modem, or would it be the next router following the 1st?

I want to safeguard against this company hacking my computers and banking info, etc.

Can somebody educate me on if this is possible and if so, how it should be done?

Thanks so much!

In theory, you could separate the networks by having two routers and modem.

Connect both routers to the modem and have them do their normal NAT and firewall stuff.
This assumes that your modem can give you two public IP addresses and not just 1. (one for both routers)
This will mean that camera's can't really access the computers network and same goes other way too. (you would need to connect to camera router either by wifi or lan to see them) or go through the internet if that app supports "check back come" feature.

Then no data from camera router should be able to access things on other router.

If you can't get two IP's from your ISP, it gets more tricky since you would basically have to set one router after the first, causing you...

If you can't get two IP's from your ISP, it gets more tricky since you would basically have to set one router after the first, causing you to have two NAT's in series, which usually doesn't play well on how the network works.
Since you don't want the camera's to see/access your computers, you would need to use the camera router first and connect the computer's router to that.

The 2nd answer you gave is actually the one I sought and it works perfect. It was discussed here with all the specific questions answered:
