A man accused of filming people in railway toilets without them knowing has fronted local Parramatta court.
A 40-year-old man is likely to plead guilty to all offences when he faces court again next month, according to his lawyer.
NSW Police have issued a warning to the public about the placement of cameras inside public toilets.
"Anything suspicious especially in public toilets needs to be reported," a police spokeswoman said.
"I'd suggest first going to the manager and then reporting to the police.
"There's a man facing court today and the message is if you do this you will be caught."
