krbuckPrice is good, reviews are spotty. Sounds like they can be a pain to setup on the network, but once that's taken care of they're pretty good. I'm considering a couple myself.
krbuckNever heard of this brand. Amcrest has a couple of nice packaged DVR solutions (with 4,6,8 bullet cameras + 1TB DVR box) or you can just buy any camera and build a security solution using a Synology NAS (Surveillance Station software included).
