Is there any way to convert a wireless g adapter to receive wireless security camera signals?

Now-a-days computers have reached a new age where you can connect anything without using Ethernet or any cable wire. You can also receive a signal from wireless security camera ASTAK 860Q through wireless adapter-G and convert it into a receiver that can receive the signal from the wireless camera. There are two type of wireless cameras available. The most common type of inexpensive camera that can able to transmit an analog signal on 900 MHz and second one is 2.4 GHz used as the receiver that gives output of composite video. This kind of camera requires an adepter-G which can capture any video and send it to the computer. For receiving a signal from wireless camera you need a wireless bridge to connect the network’s signal to server’s Ethernet. But the cost of this bridge is more than the wireless camera ASTAK 860Q. Another solution for receiving the signal using multiple cameras is to connect each camera’s receiver which has network capability. This will allow you to see up to 4 or 8 snaps online. It is cheaper than the process of server. The bridge is important to connect to your wireless camera for high performance of receiving so that you can able to use your adapter as receiver with your wireless camera.
