Hello! At 1st I need to say I've deployed about 5 PC based NVR systems with 1 to 15 IP cameras and 2 systems based on Hikvision NVR DS-9616. Cameras used - Hikvision DS-2CD2032-I, DS-2CD2132-I, DS-2CD2012-I. So I think I have some expierence with networks, cameras and DVRs. Recently i'm stuck with one PC-NVR.. The situation is sad there are powerful and expensive PC: Intel i7-4770 @ 3,4GHz (integrated GPU HD 4600), 8GB DDR3, ASUS B85-PLUS MB, WIN7 Pro 64bit and 9 cameras DS-2CD2032-I The software installed Hikvision iVMS-4200 PCNVR v1.03.00.04 (Windows) and there are 90-100% processor usage when viewing all 9 cameras online and I'm sure it shouldn't be so. Last summer I set up CCTV system with 15 cameras and computer was weaker ( if i remember it was one of i5), but there was no problems. I think there are some iVMS incompatibility with 64bit system or i7 processor or GPU. Or I should add some GPU card to PC? I have no IDEAS. Maybe other members have any suggestions? Thanks a lot!

really funny.. Today I connected more 3 cameras to my largest system - now there are 18 3Mpix cams streaming FullHD and everything works very well. I even think that i7-3770 is overkill for PCNVR. But about my trouble.. I tried to install different versions of PCNVR, nothing changed. today I tried switch to 3x3 view in my working system - everything works well. And 2x2, 4x4, 5x5 too. Then I inadvertently made some captures in different views and.. woilaa.. in 2x2 view - captures are 1920x1080, in 3x3 - 4CIF 704x576 SubStream. Then I did the same in my not working system - in 3x3 view captures was FHD.. like drocer said. But in 4x4 view procesor usage is acceptable because showing substreams. There are different monitors - the working system - 1280x1024, but not working - 1920x1080. So i dont know why in 3x3 view PCNVR doesnt show all SubStreams. Theoretically 1920/3=640 so there's no reason for showing main stream. And don't say Hiks didn't know that.

Hello Everyone! Today I found in my notes some scratches about PC, where everything works well with 15 cameras at 1920x1080. There is Intel i7-3770 (not K). I found some compares: http://ark.intel.com/compare/65719,75122 so there are some differences and GPU - HD 4600 vs HD 4000. Also i was focused on GPU differences, where 4000 is ahead 4600 only in GPU core speed, I found IMHO more important difference in CPU - 4770 doesn't support 32bit Instruction set http://processors.findthebest.com/compare/810-1033/Intel-i7-3770-vs-Intel-i7-4770 but Hikvision PCNVR is *32 (@ task maneger shoot). This can be the main incompatibility. So the test I think about - install some 64bit NVR software like MR2 prefers.

CPU usage was about 40-50% with 6 (or 7, I guess) cameras. With one cam - less than 10. Looks proportionally. I'm planning to visit the computer i mentioned (with i5 and 15 cams) in some next days to see what's else different. I know about camera firmwares and PCNVR soft (older). And I had set the bandwidth limits for cameras to about 80-90 Mbits/s total (about 5Mbit/cam). (In this system about 45 total) There can't be something related to h264 software vs hardware decoding?

actually i haven't try anything with this PC because lack of time. Yes, the driver for video is the newest one from Intel. and today i got answer from Hikvision Hello Mr. Mariss, Due to the PC performance limitation I'm afraid it's very difficult to achieve a lot of cameras Live View in one PC/Monitor even using a i7 CPU for instance. Besides you need to consider the network bandwidth and a long term stability! That's the reason why we limit to 64 cameras max. In your mail you mentioned that PC gets 90-100% processor usage when Live View up to 16 cameras? I think you'd better check the PC performance, Graphic Card and Network conditions. If possible, please do consider to lower down Bitrate and FPS or do get Live View by Sub-stream (lower quality video), but it could be possible to improve. But I recommend you to Uninstall iVMS4200 PCNVR (server based) and install iVMS4200 client software (PC based) available at: http://www.hikvisioneurope.com/portal/index.php?dir=Software/02%20%20%20Video%20Management%20Software/00%20%20%20iVMS%20for%20Windows%20OS/01%20%20%20iVMS4200/iVMS4200%20v2.00/Multi-language/# Also you need to install webcomponent for your web browser into a 64bits OS: http://www.hikvisioneurope.com/portal/index.php?dir=Software/03%20%20%20Web%20Components/Multi-brower%20web%20video%20componet%20for%20win64%20v3.0.3.3%20build120419_en/ Note: We kindly request you to click on REPLY into your email client in order to keep all communication together.

There are some shoots from that system: I'm too thinking about onboard video.. but using it wasn't my idea. It seems to be solved using lower frame rate for cameras (not default 25 fps). But it lowers framerate in recording too. Its reasonable price for 6450, maybe it worth a try. Another idea was to ask Hikvision support some advice.. Now-one knows about their software more than they. === Today i tried some of that cameras in BlueIris software on another PC - result is the same.. It uses too many CPU to decode many 1920x1080p h264 streems..
