Wireless Security Camera
Wireless camera systems are growing very popular as the technology has become advanced enough to be affordable. Wireless cameras have a wide spectrum of uses that range from video surveillance to picture sharing over a wireless network. These WIFI enabled cameras are useful in home security systems or for parents to check up on their baby sitters. They are equally popular as corporate CCTV solutions and as webcams for a home user. The user can allow another internet user to both see and hear him using internet technology. Many users use these cameras to catch up with long-distance relatives and friends.
Wireless cameras allow a user to connect to a wireless network without the need for any cables making it possible to download images directly to a computer while capturing them wirelessly. Since they are connected over a wireless network, the data transmitted can easily be encrypted using wireless router configuration. With the amazing adaptability these cameras offer, users can even connect wireless cameras to a cellular network and share photos just as in a camera phone, thus eliminating the need for any card reader or USB cable to download videos or print photos.
In operation, wireless cameras share similarity with other type of wireless devices and differ only in that the radio signals sent by these devices are converted to digital images or video data. These cameras use wireless computer network technology (802.11b and 802.11g) to connect to a wireless network. Wireless cameras usually come with several components that also include wireless receiver which can detect and receive signals from multiple cameras at once. The receiver is easily plugged into a monitor to view the images. It can also be connected to a storage media with the same ease. Wireless cameras also offer amazing portability features and many come with mounting brackets which can be just as easily concealed anywhere in a room.
The usual recording resolution for these wireless cameras is 320x240 pixels. At this resolution, a space of about 200 – 200 MB per hour is needed to record videos on a storage media. This makes about 5 – 6 GB of storage requirement every day. Cameras with a higher resolution use exponentially more storage. Keeping this in view, it is generally a good idea to keep 30 to 40 percent of the storage media vacant.
Wireless camera systems available today can be battery-powered or connected to an AC power outlet. Battery-backed cameras offer ultimate mobility without the need to connect them to power outlets and making their location more obvious in video surveillance systems. With lighter weight high-capacity batteries reaching the consumer market, battery-backed cameras are increasingly becoming the prime choice of users.
Wireless connectivity is what the future would be. Although wireless cameras are still relatively new in the consumer market it is only a matter of time that they offer users image quality and features that would easily rival the best digital cameras available. More and more users are then expected to opt for the option that gives them freedom from unnecessary wires and provide them the ease of installation and superb mobility.
