Hidden Cameras With DVRs
Until recently, what a hidden camera saw had to be viewed using a VHS recorder or a DVD.
Now, through advanced technology and smaller technology, the size of DVRs (digital video recorders) is getting smaller and smaller. This makes it easy to place a DVR inside an object along with the hidden camera.
Many people have made money selling hidden cameras with DVR. So besides protecting home and businesses, hidden cameras are helping people pay their bills when they use them to start a business or supplement their incomes.
