To set up a network camera for wireless (WiFi) access, you will first have to temporarily connect it to a wired Ethernet network in order to configure the camera's wireles settings.

Connect the camera to your Ethernet switch or router, and follow the intructions given in Setting up network cameras. Remember to disconnect the camera once you have finished setting it up, as many cameras will not connect wirelessly unless you do this.

In addition to assigning a manual IP address to the camera, you will need to enter information about your wireless network, such as the following:

I don't think it's good idea to setup the wireless IP camera system.
The reason as below:
1. Wireless transmission with scope limitation. Typically the WiFi only can cover 5/10 meters away with obstacles.
2. Even it's wireless transmission, but this doesn't mean it's complete wireless. You still need to use the power cable.

My suggestion is you can use the PoE solution. The power over ethernet technology can allow you setup an IP surveillance system with minimum IP infrastructure investment. The PoE can allow camera transmit both the data and power through single Ethernet cable.
