    Please Help or Give Advice for 64 IP Camera System

    TomCCTV, Sorry for making you confused. We, including me, used to curse a lot to Intel, MS, Mother board makers. But we found ourselves at fault, 99.99999%. No other company spend money on tech support and quality control than they do. That's what I meant to. It is much more stable than a stand alone or embedded box NVR, in terms hardware and its thousands of unknown electrical components. And it is run by Windows where we can easily know our limits, what we can do or can not. You can PM to me.
  2. ebay "web cam" or "car black box".

    a TVT DVR

    Woops, TVT is a Chinese manufacturer, not in Korea. It is not a small company. They can easily meet your request.
  4. MindTwist, We all know that HDMI can go a bit longer than VGA connection. Your wish is not the fault of DVR manufacturer's. It is limited by the chip set they select. These kinds of chip sets use their DDR bandwidth to its maximum under the allowed heat budget and number of DDRs on the board. So, it is nobody's fault, at this moment. If we guys keep raising our voices, then they will be heard by other chipset makers. How do I know? I am a chip guy.

    VideoCheez, Do not worry about stability of the software, as good as PC and MS. Usually large monitoring centers buy one more system as extra, just in case of failure and time to be needed for fix and diagnosis.

    VideoCheez, I just learned that your system might not need our solution from your messages in this thread. You can go with Hardwired stand alone DVR, or NVR or PC based solutions. I saw some vendors, based on PC software, claiming 16 Ch X HD1080P which seems not quite stable. But very simple and handy. We do not develop that kinds of small sized solution. I thought your system is made of all 64 IP Cameras of HD 1080P at 30 FPS each. FYI, the processing bandwidth of 1 Ch 1080P at 30 FPS is equivalent to 4 Ch 960H at 30 FPS. So any NVR, claiming 16 Ch 1080P, can be applicable to your need, 64 Ch analog IP cameras (D1 or 960H). If needed, you can add one more NVR to mix with some 1080 IP Cameras. Our system seems too much for you.
  7. I may suspect the camera. There are two color components U and V or Cb and Cr. That might have flipped each other somewhere in chip interface on the camera module board. Plug BNC output of the camera into CVBS or External input port of your TV set.

    In this forum, there are many threads dealing the issues that you raise. Please study them for your own.

    Videocheez, The solution is for a high end PC. But in order to protect the software, we set some hardware encryption and software itself. We provide the PC and software. You go to Bestbuy for Monitors. Because it only needs a single PC, the system takes not much space. For back up, you need to buy two system just in case of break down. The warranty would be limited by Intel's. So the maintenance and tech support is quite simple, no such headaches from using standalone NVRs or DVRs, in case of breakdown due to unknown reason. You can freely swap displaying video channels on any monitors that you choose. Excellent choice for Central Monitoring System. Big Project. But Very Expansive, you may put one more zero, I am a bit concerned. For more details, you can leave PM to me.

    Shockwave, How much for 4 sets of 16 ch (1080P) stand alone DVR?

    Video Noise multi use coax

    Beats me. But let me add. Different Source for Motor and Camera looks better scheme for noise shielding. But the thickness of cable may also be counted in. Electric Noises from Motor may creep into the image sensor on the camera board. If you have options to turn on 3D Noise Reduction on your camera or DVR side, please try. This option would be a temporal remedy.

    I think I got the solution. 64 Channels of 1080P X30FPS real time decoding and display with a single high end PC, capable of driving up to 12 HDTV monitors. But I may guess we can not make it public in this forum. You can PM me. SunnyKim

    Dahua NVR Display Issues

    The project manager may seem to have picked up a cheap or poor performing CoDec chip, just trying to send his baby out to grab the market earlier. You may return or ask for new model. That's not good.

    Issues wtih Image Quality and FPS rate on NVR System

    At the same file size of recorded bit stream, H.264 can give a lot better quality than JPEG does. When captured and viewed, a frame by frame basis, JPEG can be better. But it is an issue of Orange or Apple. As you can afford more bit stream, what's left? CMOS sensor has become very cheap, offering a good /sharp video quality, under well lighted condition. A bit old CMOS sensor may be playing a trick by interpolating VGA quality resolution to HD1080P resolution. But I always believe a good quality Lens decides everything of video quality.
  19. If you run more than 4 HD IP cameras of (HD1080P X 30FPS), even Xeon may not be able to decode all 4 channels and displaying 4 videos in real time. You can observe Lags, Frame Drops, Hangups, even though those software solution providers claim they are so good. We do develop ours that's why I know.

    Issues wtih Image Quality and FPS rate on NVR System

    Maybe lacking of processing power of your NVR. Camera side would usually be OK. You can get higher quality of video, by setting higher compressed bit stream to your camera. JPEG creates a lot heavier bit stream to be passed over networking. Network is to be limited under Max 100 Mega Bits, Not Bytes per second. Actual data load can be under 30 Mbits for safe deliver to the processor inside NVR box or PC.

    Home CCTV over 30 Meters (90 feet)

    Any camera has no problem with 30 meters. But analog camera can go longer because of its method of signal transmission than IP or HD_SDI type.

    HD capacity calculation

    Capsat, Saying 720TVL may indicate camera is analog & D1 size. Good Quality of D1 MPEG recording could cost 4 Mega Bits Per Second per each camera Average 4 Meg bits are for DVD movie quality. 4Mbits X 3600 secs X 24 Hours X 7 Days % 8 bit = 302,240 Mega Bytes/ Week for one camera. So, for 8 Cameras and for a week operation, you may need at least 2 Tera Bytes. But the bit rates can depend on the situation where camera is located. Lots of Moving Scene, Cameras not performing good for the night or low lighted, etc Best way is to give a week of trial for a good estimate. Then you can decide HDD size and number of weeks, as a safe side.

    video wall

    Can you tell How many IP Cameras? HD1080P? How many monitors do you need?
  25. MaxIcon, You could be right. I Frame carries more larger bit stream size than that of P Frame. So may be in trouble to load it for decoding buffer or encoding, due to heavy traffic load to CPU or rather small sized internal buffer. These can not be resolved by firmware alone. This happens either to a IP camera side, or NVR side, or network transit-buffer. Anyway, you better report to NVR maker. How do I know? I am a chip guy.
