In some cases the camera will pull a different IP in it's internal software as it is listed on 2 different tabs. You can correct this by finding the cameras IP address with the IPC search tool software (link below).

Open the software and search your network for your camera.

Once you see the camera listed, write down the IP address then right click on the camera listed and select "network".

Disable DHCP and set the IP address to match what you see on the IPC search tool for both network and wifi tabs.

Open Internet Explorer and access the camera by it's ip address. Be sure to enable compatibility view prior to logging in.

Click on the settings and check that the IP addresses match on the network and wifi tabs and then enter your wifi password for your network. You can then remove the ethernet cable from the camera as it will now be connected to your wifi.
