The 23-year-old Finland international is out of contract at the end of the season.
Warnock said, "I have always looked at Scottish football and he is a good player (Kamara).
"He has had an up and down start to his career, but he is one of a number of Scottish lads we have looked at. I'm not confident at all (of signing new players) as it is so difficult in January.
"But it's better for me when we have had a couple of results that we have had. It is easier talking to players when you are not bottom of the league.
"We can try and convince them we have a chance of staying up and ask them to come and help us out.
"It is far better for me to talk to players in that situation. And if you look at the club and the crowds that are following us, it is an appealing place to come to."
