Hi,
That is a very good DVR, hope that you choose the Pro version because really makes the difference. Or you could buy the Qvis Trojan 8 channel.
For the cameras, I would recommend something better than that. You said that you want the cameras with big housing, and because og of that I would recommend this HDSmartEye CCTV Camera, 1/3 SONY 600TVL 8mm Lens 50m IR or HDSmartEye CCTV Camera, Effio-E 1/3 SONY 700TVL 8mm Lens 50m IR or better than the previous 2, this HDSmartEye Super WDR CCTV Camera, 700TVL 8mm Lens 50m IR. You can choose lens 8mm, 12mm, 16mm.
I bought 4 cameras like this. The 700TVL WDR really makes a difference upon the others cameras.
You will not be disappointed.
Sorry I can not post links but I am pretty sure you can find them.
