  1. Cliff369, Your question seems directing to me. I already explained in my previous threads. We do make use of processing power of graphic card carries. No extra hardware something. Pure software. With a U$80 card, our max number of channels of 1080P (2MP IP camera) to be decoded at 30FPS in real time display are now limited to 32 Channels. Each compressed bit stream is about 8 Mbps, which is a main compressed stream, not sub stream. For 32 channles, the total amount bits to be fed from network port can become around 250 Mbits per second. So Giga LAN is must, or from HDD. I guess some others may be able to do as much as we can. But they are most likely to skip "de-blocking" procedure, which requires a lot of processing power. So a bit worse video quality that you can detect on the viewing monitor. Some branded big companies do not accept this kind of trick. The number of monitors are depending on the graphic card inserted in a PC. For 64 Channels or more, we have to use a more expansive G series card from nVidia.
  2. Please let us know if you finally solve the problem.
  3. The reason i asked the question above was to check the video decoder of your DVR, since TV view is OK, as you said. Better buy a different model of camera. Anyway, it is a good puzzle.
  4. It really beats me. Switch the input port of your DVR for different camera, Ch4 camera into Channel 1 input port, vice versa. One more question is that the picture captured has no color, in gray. How would it appear when color image is captured by the camera?, I am just wondering.
  5. BNC -RCA is just a physical interface change. Therefore, No change in the signal content. Can you see the differences from the Night and DayLight conditions?
  6. Camera output is to be CVBS TV Signal, that is either NTSC or PAL? Right?
  7. Can you change the location or lighting environments of the monitor?
  8. It is up to you to return it or not.

    SDI problem

    HD_SDI has nothing to do with broad band. It is for transmitting HD sized video data, without compression, from HD camera to the distant viewing monitor and DVR box. There video data compression takes place for network application or for recording to HDD, ever getting cheaper and bigger.

    you ever seen these DVR specs?

    960H is a new sensor & new data size format driven by Sony CCD. 960H is 960 Pixels in Width(Horizontal direction) and 480 Lines(NTSC) or 576 Lines (PAL). It is bigger than conventional D1 , say 720X480(NTSC 30FPS) or 720X576 (PAL 25FPS). 960H carries more horizontal resolution (33%) than D1. Just as CIF (352 X240 or 352X288) is for a quarter of D1, Q960H becomes (480X240 or 480X288), a quarter of Full 960H. Four 960H video channels fit for HD 1920X1080 sized monitor. The 960H is newer therefore, more technically advanced in Sensor's noisy reduction and Image Signal Processor attached to its sensor. The Price becomes now as good as D1's. But to me, the video quality depends largely on the good Lens that you pay for.

    you ever seen these DVR specs?

    Yes, it is D1 and Full D1 that they named or typo in its printout.
  12. Yes, we do and can, I am repeating. but no idea of the differences what's consumer or professional cards. We use G series from nVidia. Nothing else. With 64 Channels of 1080P bit stream , No problem. Around 100 Channels of 1080P compressed stream could be the bottleneck when reading out from a HDD. But it is not really because there could be multiples of HDDs or Multiples of Gigabit Internet ports or SSDs(solid state device-new & faster hard disc). Currently, we are looking at a graphic card of U$80. With that we do decode almost 32 Ch 1080P, each 30 FPS. What I mean "almost" is that we are now trying to reduce the CPU load to less than 35 %. The reason is that we have to allow system makers or developers to put on their own value added/enhanced GUIs or applications, say object tracking, face recognition,etc. I will let you know when it is on the market. I left a PM, last night, arriving to you, soon.
  13. Drocer, There seems to be misunderstanding. If you have decoded video data of 64 Channels of 1080P from 64 channels of main-bitstream (compressed), you can not display all of them on a single monitor. You have to scale down those decoded video into a smaller size to fit into 4X4, or 3X3, whatever configurations, or the number of displaying monitor. That's why I used "scale down". I understand that zooming up might be needed if decoded from sub-stream compressed files.
  14. We actually had a small booth in ISC-West 2013 and Shenzhen last Oct, showing 128 Ch on two monitors. We did not make any good opportunities. They did not seem to buy us much. So this time we would not be there. But I will be there, myself. You can call me then.

    Winter camera

    The chipsets are to be operated in the range of -20 C to 70~80C. As chipsets are supposed to be driven by electrical power and generating heats a lot on their own. Low temperature does not matter. But humidity and hot temp does.
  16. AK357, Absolutely not. One nVidia graphic card can drive one, two,three, and up to four monitors. But decoding 64Ch X HD1080P X 30FPS in real time will be done on a single PC. If an nVidia card can drive 4 monitors, then each monitor can be set to display 16 Channels (4X4), or whatever display configurations that you like to see. Each video is to be decoded from its own HD 1080P compressed stream, not from its sub-stream. And they are to be scaled down to compose multi channel display on each monitor. You can move around Main display to any monitors of interested, on the fly. For more info, you can mail me. We should respect this should not be flooded with ad. But I think I have to correct any misleads or wrong concepts.
  17. Drocer, No tricks. Simply i7 CPU plus a single nVidia card. Simply a PC. No more extra hard-wares or something. I will make you see and believe that. There are always smarter engineers out there than you have seen. Want to know more, mail to me.
  18. Cliff, You are correct Nobody can. But ubiqmicro can decode 64 Ch X1080P X30 FPS in real time including de-blocking filter on a high end i7 CPU and nVidia card. I mean it. Are you coming to ISC-West?
  19. The flash memory are not durable, and of small capacity, usually limited to several thousands of writing into and reading from. Handy and Good for temporal storage, but not good for year span usage.

    ISC West 2014 - who's going?

    I will be there, too. We used to carry our own booth, ubiqmicro, but skipping this year.
  21. Over 800 TVL may be designed for HD sensors which have different type of transmission of Video Data Captured, say HD-SDI, IP Camera, HD-CVI. These may cost you more and more complicated when installing and using its software and hardware.
  22. In Canada, you set NTSC and 960(horizontal width) X 480 (vertical line) on your camera as well as your dvr. 576 Line is for PAL. The TVL number greater than 650 could be targeting 960H. 960H is based on the newer sensor(may be solely from Sony) and newer image signal processor chip(eFFIO and some new other chip), so most likely to have a better quality than old conventional D1(say, 720 X480) camera. But always remember that the good quality lens decides 90% of the video quality. You can guess Lens quality from German, Japan, Korea, and China, in this order. 960H is analog camera. So you may have to check before hand the cameras that you select should output 960H CVBS format.
  23. You may look at http://www.ebay.com/itm/NVC-1204C-CARD-960H-960x480-4CH-120fps-Korean-Made-US-Seller-for-Tech-Support-/121200119896?pt=US_Surveillance_Security_Systems&hash=item1c38171058
  24. Decoding 16 Ch X1080P X 30PS in real time on your i7 model and displaying them for a live pre-view could be OK, as I heard. If the software provides an option to disable (off) "De-blocking filter", then do that. De-blocking operation cost really a lot CPU power. You can save some. If no option, that means they already do not use Deblocking costing some video quality. SSD offers more bandwidth than HDD in speed of reading from & writing into. But no gain for your system in hand because total bandwidth will not be greater than 50 MBytes or 400 Mbits in total. Transcoding does encoding a H.264 encoded bit stream into another sub-stream of h264 of smaller size and fps, or another encoding format, say jpeg or mpeg. So transcoding would take a lot of CPU, DDR, and HDD bandwidth. Do avoid transcoding. Your IP cameras may provide a substream in addition to main HD compressed bit stream. Use it for decoding and displaying for 3X3 or 4X4. That could be your option to save. Varascope, We use nVidia instead of ATI. I left my message to your PM. If not, let me know.

    Door sensor triggering. How to?

    A sensor output goes into the input of the CoDec processor of the camera or DVR. What they call is GPIO pin of the CoDec. At least you should check the product you buy must have an external sensor input port on the box. Then the software they provide carries its menu for you to enable or not.
