'Good behaviour' guidelines have been released for politicians and political journalists using social media at Parliament.
The new guidelines recommend restricting politicians from taking photographs or filming each other while Parliament is sitting, or while they are at select committee meetings.
The report notes there may be a few exceptions such as MPs' maiden speeches.
Politicians have also been reminded that any comments they may make on social media while Parliament is sitting are not covered by parliamentary privilege, and they could be held legally liable.
The Privileges Committee, which developed the rules, also said it was time to reconsider rules which prevent television cameras from filming disorder in the House or using footage for satire.
The report notes 105 of Parliament's 121 MPs have Twitter accounts.
