Hi, Just a quick question on which NVR to order from Andy. I wanted to setup a NVR at my dads farm. He passed away and the property is vacant. This is a rural property with no internet. I just want to set up 3 IPC-HDW5231R-ZE's that will record to a NVR. I visit the property once a week to cut the grass, etc. and I want to review tape in case of theft/vandalism issues arise. I just want to do a dump of video files onto a portable hardrive to take home and review. Any thoughts or recommendations to these NVR's listed below so I can place the order? I am looking for decent quality and durability as it will be placed in a shed that endures various temperature changes of a Southern Ontario/Michigan environment. NVR4108-8P-4KS2? NVR4208-8P-4KS2 NVR5208-8P or anything else you suggest. I assume a 4gb hdd will be plenty if cameras set to record motion events? Thank you, I really appreciate some advice.
