Just joined the forum to chat about the new NVR's avab. Little background... I started playing with security cameras in the house back in 2004 time and had a PC running Blue Iris with 8 Panasonic wireless IP cams it worked pretty well for what it was. Blue Iris was great and he would help with anything I needed. Then I moved to a stand alone Revo America 16 Ch DVR which I'm still running today. Think I got it from Sams club and it's been great. I have PTZ's and all running on it 14 cameras total. I also installed an Ademco vista 20p alarm system panel and setup all on my own and it's wired into the Revo system through the alarm inputs to change recording setting if the alarm trips. Revo is good they give you a lifetime DNS service, but pretty proprietary setup there android app lacks luster but over all it been a good system. I am now gonna start running some Cat 6 to where I have cameras now and get ready to replace everything to an IP NVR setup. I have noticed that in the NVR, DVR, PC's Cat on this forum that Dhaua and Hikvision are talked about alot. I was looking of staying away from them and maybe get another Revo HD NVR and or the system that SCW have to offer. I know revo and they are ok and it works. I would get another 16ch NVR for sure. Both Revo and SCW NVR are ONVIF... Still doing my home work and have plenty of time before I decide on what I want to get.
