As evident from the name itself, fake security cameras are meant to be mere deterrent for the visitors to give an impression of a surveillance camera installed. Some dummy cctv security cameras are available now with battery operated red LED lights on the front to make the dummy camera look even more realistic.
Night vision cameras are suitable for any low-light area and record images in black and white for best results. Home surveillance cameras are often accompanied with facilities like motion sensors for effective spying.
Covert surveillance cameras look like regular items that can be anything from a wall clock, a potted plant to a soft toy of your kid.
These types of hidden miniature covert cameras are very small and can transmit a video signal to a nearby van or recording device. Often covert cameras are used by a spouse or private detective on behalf of a spouse to spy on their partner. Also a recent common use for miniature hidden cameras has been to keep an eye on babysitters and other domestic help to make sure they are acting accordingly within your home.
Wireless security cameras are portable, discreet and often small in size. These cameras are very easy to install and can send a wireless signal a fair distance back to a recorder or monitor system. Wired surveillance cameras on the other hand, suit only a permanent set up and can be more difficult to install due to the laying of wiring back to the recording or monitor device.
In a nutshell, there is really no end to the sophistication that may be explored and gained among devices for audio and video surveillance. All you got to have is the willingness to buy and the budget to afford.
