Antitrust 0 Posted September 16, 2014 Hi guys, I have just built a new system which includes an i5-4440, 8GB RAM, Samsung EVO 840 boot drive and separate recording drive. Running Windows 8.1 Enterprise x64. Its only purpose in life is to run iVMS4200 PCNVR v1.03.06.02. There are 2 cameras connected: 1x 2CD2632F-IS @ 1080P, 25 FPS and 1x 2CD2332-i @ 3MP, 18FPS. The 2632 is displayed on a 1080P monitor 24/7 and the network infrastructure is 1Gbps. Currently no VLANs or QoS. I am not currently recording. The issue I have is the longer the live display is open, the worse the fluidity becomes. When I open the application the stream is perfect, however the next morning it staggers to the point where it is almost unwatchable. It appears to stagger on the iFrames. I have tried different bitrates (VBR and CBR) from 2048 - 11264, and changed iFrame to 1/2, 1:1 and 2:1 of the FPS. Closing and reopening the application resolves the issue. CPU usage sits at about 12%. Currently application setting is set to "Fluidity" It is a complex, dynamic scene with moving branches relatively close to the lens, a busy road in the top half, my driveway and front door in the bottom half.Any suggestions would be much appreciated, as although the image is sharp the live view is worse than my 600TVL analogues I have just replaced. Thanks in advance! Share this post Link to post Share on other sites
abdelm01 0 Posted September 16, 2014 Doesn't sound like a camera issue, more of an issue in the PC , what type of video card do you have on it and please post screenshot when it happens so we have a better understanding on how it looks. Also if you are not wanting to record, it would be better to use the IVMS_4200 Client for your camera viewing Share this post Link to post Share on other sites
Antitrust 0 Posted September 16, 2014 Thanks for the response. I agree that it sounds like an issue on the PC side. No graphics card, I am using the integrated Intel® HD Graphics 4600. No recording yet because I'm not going to waste my time if this solution does not work but I do intend to record. Screenshot I don't think would be very helpful, image is very good, it just hangs on iFrames after constant streaming. Imagine watching an hd movie, but every second or 2 someone pauses it for a split second, then plays again - constantly. Even changing live view to the second camera and back to this camera resolves the issue. Share this post Link to post Share on other sites

Even changing live view to the second camera and back to this camera resolves the issue. I don't recommend using the integrated video card on the pc, it is better to have an external one. We sell Systems that hold thousands of cameras, one specifically hole 3800 cameras. Everything is going through the servers and then our custom built PC's(48 of them) all pull from the servers and this is a casino environment with 24/7 monitoring and they CANNOT have any kind of error or down time and each computer has 4monitors hooked up to them 2 of them are 4k 65in and the other 2 are 24in and each operator can watch up to 80 cameras if wanted to. But first thing that i would do is order a high capacity Graphics card and make sure your power supply can handle it also. It usually does that because over the day after running all the time the GPU in the motherboard slows down and not pushing the constant video in high resolution. It is always good to most separate components inside of a computer to run efficiently. And that lag, i have seen it before, make sure your sub stream is set to higher bitrate and frames per second, also i would keep a constant 4096bitrate on the mainstream. What kind of switch are these cameras attached to and are you pulling through wireless or ethernet Share this post Link to post Share on other sites
Antitrust 0 Posted September 18, 2014 Thanks mate. I have a gfx card I can drop in after work so I will see if that improves this issue. Switches are Cisco SG300-10 and SMCGS8P-Smart. Using my laptop and the latest HiKVision client app the image and fluidity is flawless, same as the live view on a web browser. I have tried installing a slightly older PCNVR 1.3 version on the troubled box. If gfx card does not fix it I may try v1.2 or another vendors software.
