Wifi Spy Cameras- Overview

For past few years, the term ‘espionage’ was limited to obtaining secret or confidential information without the permission of its holder. It was most readily associated with state spying on potential or actual enemies, primarily for military purposes. With the passage of time however, the concept of espionage or spying has evolved considerably. It is now not just a part of effort by a government or institution, but has become a common means for ensuring security. A spy camera is the device often installed inside houses, offices or other establishments for recording still or video images of people without their knowledge. It is often referred to as the ‘hidden’ camera as the device is not visible to the subject being filmed, or is disguised as another common household object. For household surveillance, a spy camera is often built into smoke detectors, clock radios, motion detectors, ball caps, plants, cell phones, and other such objects. Besides wired models, a spy camera is also available in wireless versions that transmit the video through air to a special receiver. The video signal is picked up by the receiver, which then converts it into a video feed. The video can then be watched on a TV or any other recording device like VCR or DVR by connecting it to the receiver. A self recording spy camera has also been introduced in the market so as to discard the requirement of receiver or an external recording device.¬†spy camera with audio¬†offers excellent info on this.

An alternative to this camera is a mini camera that is characterized by compact design and portability. Easy to camouflage, this camera fulfills the purpose of keeping watch over unwanted elements in a discreet manner. A mini camera is most extensively used by the FBI, police and other law enforcement agencies. However, easy availability of this camera has led to its increased usage for keeping watch over babysitters, guests or anyone at home. Being small in size, a mini camera easily fits into small locations and can be disguised into everyday objects like tissue boxes, plants, clocks, books, and more. However, the small size does not affect the image quality and area covered by the camera. In fact, a mini camera has the capability of transmitting signals over a large area, whilst allowing individuals to monitor a location from afar. With the advent of such modern technology cameras, security is no longer a matter of concern as individuals can keep watch over their house, office or any place through these cameras.
