Pulis was impressed with American summer signing Cameron in their 0-0 draw with Arsenal.
"We watched Geoff quite a few times and he's a good player," Pulis said.
"He's been away in America for 10 days and only trained one day with us. We couldn't get him back as he had to get some clearance and we have to wait 10 days to get him back.
"I was out in America and he played three games there and I was very impressed with the standard."
