After two seasons, the goalkeeper is a free agent after the expiry of his contract.
Camp, 35, agreed a short-term extension to his deal after lockdown in order to play in the remaining games beyond 30 June.
In all, Camp made 86 appearances for Blues after joining on a free from Cardiff City in August 2018.
Apart from a spell out of the side in December, he has been Blues first choice between the sticks.
Camp - who kept 19 clean sheets for Blues in the league - established cult status among supporters for his displays and manner, and his penalty saves became a feature of his time at the St. Andrew's Trillion Trophy Stadium.
Off the field his open and entertaining persona earned him friends too.
We would like to thank Lee for his performances, professionalism and all he has done during his spell with us. We wish him every success in the future.
