Wireless Backup Camera
There are five main categories of wireless cameras: cctv cameras, pc cameras, ip network cameras,
consumer digital cameras, and camera phones. CCTV Cameras send an analog video signal from the
camera/transmitter to a receiver attached to a monitor or TV. Closed Circuit Television Cameras are
generally used for monitoring, security, and surveillance. The cost of these Best backup cameras range
anywhere from $50 to over $500 dollars. The higher end cameras generally offer better image quality
and features like remote control. Some CCTV Cameras are weatherproof and have infrared lighting
which makes them night vision capable.
Some cameras stream video images that are color while others produce black and white. The maximum
range for most of these cameras is up to 300' straight line of sight. This is due in part to the FCCs tight
regulations with regard to power output and interference. These cameras range in size from quarters to
footballs. The smallest cameras are easily hidden and work great for surveillance.
PC Cameras (WebCams) generally send an analog video signal from the camera/transmitter to an
analog/digital receiver that is attached to a pc through the USB port. With the right software and a high
speed connection, the images can be viewed over the internet. These cameras are adequate for the
most basic pc and internet viewing. A pc is required in order to use these cameras and only a single
camera can be viewed. These camera systems generally range in price from $100 to $300.
IP Network Cameras (Internet Cameras) are stand alone units with a built in web server and cpu that can
send either video or still images. With a wireless router and a high speed internet connection, these best
backup cameras can be accessed from just about anywhere. Since these cameras are ip based, multiple
cameras can be viewed through a single connection. Some of these cameras have pan/tilt/zoom
capability, motion activation, night vision, weatherproof housings, and two way sound. These cameras
are ideal for viewing your home or children remotely and are considered by many to be the ultimate
nanny cam. The price of these systems range from $100 to $1000. Consumer Digital Cameras use or will
soon use wireless technology to transfer images to other devices like printers, pcs, cameras, and cell
phones.
Since the image quality of todays low end digital cameras is considered good, mega pixels are no longer
the distinguishing factor when considering a purchase. Wireless connectivity and image transfer
capability between digital devices will soon be the primary driver. Several of the digital camera leaders,
including Kodak and Nikon, already offer wireless digital cameras.
Camera Phones also use wireless technology to transfer images to other digital devices. As the quality of
the embedded image sensors increase, so will the adoption of these devices for mission critical
applications. The majority of new cell phones in the US now come equipped with a built in camera.
As the lines between wireless imaging devices like camera phones, wireless security cameras, cell
phones, and consumer digital cameras blur the need arises for an integrated set of websites that contain
relevant products and information.
