Can I remotely access my router to check temps and webcam?

I can't say about that particular router.

But most routers allow you to turn on specific port/ip services. Which is what you would probably need to do this..

That being said, there are reasons why those ports and services come off by default. Turning them on opens your home network to external "hacking" access.

In other words, this is not something a non-techie should consider doing.
