Anyone know the main difference between these units? http://www.dahuasecurity.com/products_category/nvr-100.html I purchased the lorex (hikvision) costco system, and the fan is too loud for me. Looking for an alternative. Will the hikvision 3PM bullets that came with the Lorex system work with either of these Dahua NVRs? Thanks in advance.

Thanks Vector. I guess I'm too lazy to do the direct comparison myself, too. Any thoughts on the hikvision camera compatibility?
