Not sure if you've ever used or had their cameras, but they're pretty good!
They have PTZ cameras, bullets, dome cameras and more. IP based, but also have analog I believe (if you're old school). They also have excellent DVR's. One of them is compatible with IP and analog and works pretty great too. You just have to stick a HDD in it yourself, but it's simple..
The ones I was looking at are 5MP, 4MP, and 3MP. They have a range, but well worth the money if you're wanting to spend it.
