Wireless Camera For Surveillance And Monitoring

A wireless camera can acquire images or video and broadcast them to a television

or computer monitor without having a direct connection with the display monitor. This is realized by relaying image/video data through radio signals. Wireless cameras are, therefore, very simple to use when the placement of cables is hard to implement or even impossible. Wireless cameras normally require a mains power source, however, battery operated cameras are also available, though the batteries necessitate recharging in a couple of hours. Use of batteries renders the camera totally portable, but obviously, it is not a preferred solution if a property or an asset needs monitoring for extended periods of time.

Wireless cameras are frequently used for observation and premises-monitoring. Some wireless cameras are designed to work with personal computers (PCs), so that recorded clips can be viewed on PC monitor, while preserving the video or images on the hard-disk at the same time. Another breed of wireless cameras utilizes internet protocol (IP). These cameras can be usually set up as internet servers and the images or video captured by these cameras can be monitored anywhere in the world using an internet connection.

A wireless camera is a terrific option for video surveillance. This kind of camera is suitable for both home and business. A wireless camera in use in UK/Europe at 2.4 GHz. can normally provide coverage up to a range of 100 meters. It is recommended to check the laws of your state or country before using a wireless camera for surveillance. A wireless camera for surveillance can be used as long as it is used in a place in which people could have no expectation of privacy. Such places may include a busy shopping street or the inside of a retail store. However, legal issues may arise in other situations. Some people opt to use wireless cameras to keep tabs on their babysitters or day-care providers. In such cases, wireless cameras are hidden from view or camouflaged, making them practically impossible to detect. It is likely that recording video or images in secretive manner in these conditions may not be of significance at all, because you would be breaking the law. Hence, it is imperative to check your local laws before employing a wireless camera for such a purpose. Although, not very dissimilar from the wired (USB connected) webcams, wireless cameras are also used as webcams. Using this technique, a building, for example, can be viewed from four sides and the images or video can be transmitted to a far-off location via Internet. In a similar fashion, an official meeting of individuals or groups in the same premises or in different geographic locations can be arranged, recorded and relayed to the head-office at the same time. Many online-users use wireless cameras to connect with long-distance relatives and friends, chat online, and even participate in the online dating scene.
