Cllr Toireasa Ferris said €200,000 has been already invested in an attempt to bring this technology forward.
Cllr Ferris said recordings should be maintained for historical purposes, so that in 50 or 60 years time people may access actual chamber discussion.
She said the presence of such technology may also help to “temper” some of the comments made in the chamber.
She said this may provide more of an incentive for some councillors to consider their remarks and in some cases, “think before they speak”.
Cllr Ferris said her own personal experience with a national newspaper has highlighted the need for accurate digital recordings.
She added access to recordings would provide a far more sensible approach if the need for review arose.
The Sinn Féin councillor called on the council to address the issue at the CPG meeting this September.
