Proactive_IC

Our company installs only standalone DVR/NVR products right now, but I am interesting in pushing towards PC based NVR solutions. I have been doing a bit of research on the subject, and trying to glean as much information as I can about all of the different software methods of doing this, but without using these products in the field, it's hard to judge them. So I ask any other security professionals, which software would you recommend for professional grade installation. No mickey mouse, finicky stuff.
