For Any Use You Can Think Of
Lack of restrictions is the key with small wireless hidden cameras. A person can even wear these cameras on their self. Companies manufacture small wireless hidden cameras like the wireless pinhole cameras, in neckties, baseball caps, and even pens.
There is a hidden camera for almost any use you can think of. One important thing to remember about small wireless hidden cameras is whether they are used for video surveillance or for other purposes, is that they are not available with audio. It is against federal law to use audio in such a covert manner. Only the law enforcement has access to hidden cameras with audio.
