OK folks. Newbie here. Bought a 4 Ch DVR and 2 cameras about 2 years ago. Mounted the cameras but didn't know where I wanted the DVR. Current wiring is exposed inside and outside to our TV and we were able to change the input on the TV to RBG and see outside. Since I didn't have access to the internet from the TV, I never installed the DVR - that is until this week. So to the best of my knowledge, the sticker on the back says VC SYS-4WEBMVP. I searched the forum and did not find anything on the 4WEBMVP. I googled the product and it looks identical to the AVTECH KPD674. My firmware version is 1036.1014.1016.1016. If this is indeed the same box, I don't know how/where to find the model suffix (A,B,etc). Can anyone help me figure this out? Would a firmware upgrade be beneficial for me? Here are the comparisons of what I have and the 674. Thanks in advance for your help. FYI I am in the USA if that matters. http://alatest.com/reviews/other-electronics/yy-vc-sys-4webmvp-4-channel-dvr-vga-out-1-sata-hdd-bay-h264-build-in-server-with-network-mouse-ready-without-hard-drive/po3-120534030,310/ https://www.google.com/search?q=avtech+674&biw=1024&bih=609&source=lnms&tbm=isch&sa=X&ei=A42IVJORKoSTyQTbkYCQBg&ved=0CAcQ_AUoAg#facrc=_&imgdii=_&imgrc=Pqt1DIw7vEl61M%253A%3B2STw6d1zzC45kM%3Bhttp%253A%252F%252Fi.ebayimg.com%252F00%252Fs%252FNTEwWDUxMA%253D%253D%252Fz%252F-9QAAOSwxH1UGum0%252F%2524_35.JPG%3Bhttp%253A%252F%252Fwww.ebay.co.uk%252Fitm%252F4-Channel-CCTV-Camera-AVTech-DVR-AVTech-674-H-264-Remote-Access-via-Networ-%252F271501374422%3B300%3B300
