A home wireless surveillance camera can make installation of a home surveillance system a snap. A wireless camera utilizes wireless technology to send the video through the are to a receiver or other receiving device.
If you have the choice, use a wired camera whenever possible. Wireless cameras should only be used in locations that wires can not be run or when installing a camera that will be frequently moved. Wireless cameras are more expensive and have more interference resulting in poorer picture quality than a wired camera.
You can purchase several different types of wireless surveillance cameras.
Analog 900 MHz, 2.4 GHz, and 5.8 GHz
These have a range of 200-300 feet line of site (nothing in the way). When you calculate in walls, electrical interference, furniture and other obstacles your distance can be dramatically reduced. It is hard to say exactly how far one of these will work in your location without trying it first. These can also pick up interference from wireless routers, baby monitors, cordless phones and other wireless devices. The 900 MHz model is less likely to pick up interference as there are few devices operating on the same frequency.
Digital wireless cameras
These cameras send analog video signals encoded as digital packets over high-bandwidth radio frequencies. This results in greater video transmitting distances up to 500 feet line of site. Digital wireless cameras provide higher video quality and great security of your wireless video. These cameras also have 2 way communication allowing you to control other aspects of your wireless camera.
IP or WiFi wireless cameras
These cameras broadcast at 802.11 MHz to your WiFi network. These cameras are capable of sending a signal in full HD at 1080P and higher. You will find these to be the most expensive of the wireless cameras, but they can utilize computer software in place of a physical DVR. Eliminating the DVR helps make up for the additional costs of the cameras. IP cameras many times come with software to manage the video the cameras capture. These cameras have 2 way communication and many of them incorporate PTZ (pan, tilt & zoom) options.
