I am actually a system running in a similar configuration to @Superfluous is asking about. Home Server running HikVision PCNVR downstairs om a cupboard connected to a Wifi router and ADSL. Up stairs in a cupboard I have a Dlink DIR615 router updated with DD-WRT firmware in Bridge Mode connected over Wifi to my downstairs router. Currently have 2 x 3MP IP camera's directly connected to the upstairs router and configured to run at the full 3MP resolution. I have no problems at all with video recording, no video loss or bandwidth issues. I also use the same Wifi network from a deskop PC to run the Remote Viewing client. I can view live and playback the 3MP streams to my desktop PC over Wifi whislt the camera's are still recording without any interruption to the video stream. Playback on my desktop PC is smooth and seeks are fast. I also have Powerline adators but for some reason the socket outlet in the location where the IP Camera router is situated gets a very poor signal and consequently low bandwidith. The bridge connection over wifi between the two routers fluctuates between 100-200mbps connection rate. both Wifi routers are 300mbps routers. I cant say that my set up will work for every one but I have at least demonstrated that a wifi link between remote IP camera's and PC NVR is possible with Megapixel IP cameras. Incidentally, I was planning on adding two more cameras a total of 4 so I might still hit the bandwidth ceiling of the wifi link. I'm planning to do some bandwidth testing with two PC's to find out what the practical limit is. Using DD-WRT firmware really helps to analyse the data stream to see how much actual bandwith is being used.

Here is a 10 second clip of the issue I described. Its about 3 mb so should only take a moment to load. https://www.dropbox.com/s/2tlntmqf8vrb5tf/Hikvision%202CD3332%20Problem.mp4

I read through that particular post but that is related to the camera switching between "Day" and "Night" modes at night in a brightly lit environment. I have exactly the opposite problem....plenty of bright, clear, consistant sunlight. The camera is not switching into night mode.
