This issue has been raised following a recent case where a Sydney teacher accused of punching, pinching and pushing four students was cleared of all charges.

However, local public school parent Saba Nabi said she would not support primary schools installing cameras into classrooms and raised a number of concerns.

"I think it would be a bit harsh if all the young kids were scrutinised all the time and it would also put a lot of pressure on the teachers," she said.

"The atmosphere in classrooms is quite informal but if you know that someone is constantly monitoring then that might mean teachers are more cautious.

"The privacy of a child or my nine-year-old daughter could become hindered if there are CCTV cameras and you can never guarantee that there wouldn't be any breaches as sometimes government agencies get hacked."

Dr Nabi argued that surveillance would alter the character of schools and might inhibit teaching and students' learning.

"Parents must trust teachers; I'm really happy with my daughters' teachers and if you trust each other then there isn't a need," she said.

"If I am working and a camera is monitoring me, then there's a chance that I might be hesitant and not give 100 per cent as I would always have a feeling subconsciously that I was being monitored."

A NSW Department of Education spokesperson said all public schools have access to a range of security resources, which are allocated on a needs basis.

"NSW public schools are among the safest places in our community," the spokesperson said.

"Generally speaking, NSW public schools use CCTV in one of three ways: monitoring premises for after-hours security; monitoring premises during the course of the working day for added security; and monitoring sick bays and student time-out rooms or other specific areas in schools."

Wagga Christian College principal Phillip Wilson said he has never had to consider installing cameras inside classrooms.

"I've got fantastic relationships with teachers and students and I wouldn't consider doing it here," he said.

"This is a foreign concept and I don't think they've [parents] even thought about it."

Similarly, NSW Secondary Principals' Council president Chris Presland said schools are statistically the safest place in society.

"This would only be a small number of parents who would support this but the occasional horror stories are not statistically representative," Mr Presland said.

"There are so many privacy issues that would be raised in this sort or situation and almost philosophically it would break down the trust between parents and teachers and stifle the creativity.

"People lose sight that a school is a workplace for teachers and how would you feel if you're having a camera sitting above you all day?

"You can understand why some people can be tempted by the idea but people likely don't understand the damage to that fundamental trust," he said.
