In the United States, some states have banned the purchase of hidden cameras.
In Australia, the government has issued a statement saying that “this device can be used for surveillance purposes”.
It is not clear if that means a hidden-camera detector will be banned across Australia, but it is likely to be banned in some of the US states with similar laws.
This could be particularly true in the US where there are a lot of people in rural areas who have little or no internet access and are less likely to have access to smartphones.
The US is one of the most heavily surveilled nations in the world, and there have been multiple mass shootings in recent years.
There are also concerns about the security of mobile phones in remote areas.
The Australian Federal Police is currently investigating the case of a man in New South Wales who was found dead after a hidden cameras went off in a bush outside a house.
In a statement, the AFP said the man was found unresponsive in the bush.
Police are also investigating the deaths of a 24-year-old man in the state of New South from suspected self-inflicted gunshot wounds in July and a 40-year old woman from a gunshot wound in September.
There have been several reports of children being left alone with guns in their bedrooms.
In Queensland, where a man was charged with murdering a woman after she allegedly shot him in the back with a gun he had hidden, the Queensland Police said it was investigating the death of a 16-yearold boy in February.
The Queensland Independent Police Commission (QIPC) said it had received “an unprecedented number of calls for assistance” in relation to hidden cameras in the past year.
“In the past 24 hours we have received at least two calls to us regarding a possible hidden camera in the house,” QIPC commissioner Andrew Kelly said.
“The Queensland Government has taken a number of steps to reassure the public that the safety of the public and the safety and welfare of Queenslanders is paramount.”
The ABC has contacted the Queensland Government for comment.
