There are no such DVR cards for Mega Pixel Cameras. Forget. Buy much cheaper 720P IP Cameras and its accompanied software for your PC. Then, you do not need worry about performances of PC and HDD size. You won't believe that 3MP or 4MP are based on the same image sensor of 720P. No theoretical gain, but ripping off the innocent users who think more pixels would give the more clearer video images. Simply expanding pixel counts do cause more issues: More powerful CPU or back end NVR, more HDD, more network bandwidth, more latency, more lagging, bad night vision with a lot noise, complicating softwares, all things. Of course, these could be welcome, if 3MP is at least giving you 2.5 times more contrast / detail/ true fidelity than 720P. But the time is not yet to come.

Absolutely, you need to explain the reason why the night performance of 4MP should be better than that of 3MP's. If not, I may believe that you live on commissions from 4 MP.

You may have to watch "Quick" hands. You may need a very high frame rate, say 60 FPS. You may check out the frame rate of 12 MP -Fish Eye.

AVI format is just a wrapper, carrying file header information, for Windows Application: Therefore, slightly larger than originally compressed file, say H.264 compressed in your case. But for easy & smooth handling, it is better to divide a huge compressed file into many small files of a small scale time unit, say 5 minute. My calculation goes as following. 2 Mbit per second X 3600 seconds X 24 Hours / 8 (bits to a Byte) == 21.6 Giga Bytes. 2 Mega Bits Per sceond is assumed for Max Supreme Quality for 720P at 15 FPS on average.

Absolutley OK to buy analog stand alone DVR of Daihua. But make sure it is capable of recording 4Ch X WD1 X30 FPS. Old days, most of DVR were limited to CIF recording, not WD1 or 960H.

I did not try to attack you, in any sense. It is your problem that you think you are being attacked. Sorry to say that I do not have any other languages to please you, except English. But I do ask you please. 1. Do not bash all other products that you never had experienced by yourself. If you have to, you make sure whys be explained. If not, you will not be respected. 2. Almost All the IP Cameras and NVRs are based on the same Chip/ same SDK, possibly same materials and components. When you put scarlet letters, or junk on those unbranded, you must bring on solid proof. If not, you will not be respected. Why ? Because we have to watch on "Monopoly Being Formed" all the time. We have to avoid any chances of being limited in our selection. 3. Please stop promoting 3 MPs /4MPs/5 Mps IP Cameras unless you got confirmation these cameras are not using the same image sensor as 1 MP (720P X30 FPS). That's cheating and over charging. That's horribly bad for industry developement. You may read: viewtopic.php?f=1&t=47534 . Losing credit one time, costing 100 times to re-build. 4. Writing American is OK. But Writing English needs Logic which is borne with. Feeing sorry but I Do not blame you.

IPC is not related to distance, at all. If so claimed, then IPC is invented to overcome distance issue,as there were not ways invented to send Mega Pixel Raw Video Data from Camera to the DVR where viewing and storing is done. IPC sends the compressed video data over network cable, which become so cheap and managible technically, easy for small data sizes in stead of huge raw uncompressed raw video data. Thanks for raising the question. I have to tell you that 1.3 Mega Pixel could be the best resolution worth of your dollar, as of now. Many peddlers do recommend 2 Mega Pixel / 3Mega Pixel/4 Mega Pixel IP cameras. They are using the same image sensor as 1 Mega Pixel. They simply increased pixel counts, not pixel resolution, in deed. But they can charge more money than when they honestly confess that they are using the same sensor as 1 Mega Pixel. Where's the proof? 1. Ask Micron(Optina) CMOS image sensor engineer. 2 Check out the camera spec of MicroSoft's smart phone, which is bold and challenging. If they claim 15 Million Pixels as state of art, in terms of video, only 15 Video Frames of 1 MP resolution per second. They are not close 30FPS or 60 MPS of 720P, yet. Smart phones shoots for 2 Billion pieces. CCTV, at most, shoots for 100 Million pieces. Image sensor was not born for CCTV industry. Do not be confused. If you are CEO and R&D chief, are you going for number one image sensor supplier for such a small IP camera industry? Be real and let's be honest.

Any PCI or PCI-E card capable of 960H /WD1 recording would be OK, available amazon or ebay. Remote access over smart phone is no problem. If you pay more than U$50, you are ripped off. Do not buy USB-DVR stuffs that are limited to CIF X 4 Ch recording and Previewing.

A 4 camera system for 100? That is not going to happen...you will end up with a super low resolution system that will only give you problems...save your money. How much should I pay for 4CH Cameras in your opinion ? You may follow my suggestion if limited to U$100 and 4 Ch cameras. But you need system for only patio door, you better go for an IP Camera solution-single channel. Easy and you may not need to buy POE. You just need PC and software provided by IP Camera.

Good job you did report me to the moderator. You never beeeen logical or convincing or based on facts. You are not forgiven just because you did recommend some other makers'. Let me tell you one fact: Almost all IP cameras/NVRs in the world are based on the very same chip and the very same SDK, if you check on the board, breaking its boxes. IP cameras are using TI's DSP and NVRs are using HiSilicon's. Then what does factor into "Junk" from "Excellent"? Please let me know. You must know this fact already, just because you have been peddling Grey Market Products. Smart enough to be justified from Crimes. Why pay more if they are, in fact, of the same products?

Qualitywise, HD-SDI is the best. But somewhat expensive more than other competing products, say HD-CVI, HD-TVI, and HD-AHD, etc. All of these run on BNC cables. The cable distance does not seem to be an issue (max 150ft). The thickness of cable does not prove to be a factor of cable quality.

those are junk cams and junk nvr... You dont need a gigabit switch for a few ip cameras... you can use a cheap 4 port 10/100 poe, or use a midspan injector.. When you call certain products "junk", you mean you did experience with those product. Or you are just lying? Or you just heard somebody is talking that way??? What are you founded on? Stop bashing others just because you are peddling HikVision Counterfeits.

Analog cameras, conventional CCTV cameras, output NTSC or PAL signal for carrying video images. IP cameras output the digitally compressed bit streams for carrying video data information. Please read to start with: viewtopic.php?f=5&t=47517

Well, 4Ch with less than U$100. You can start reading: viewtopic.php?f=5&t=47517

It was a Space Science, a decade ago. Not now any longer. Commodities for LockSmith.

The CPU work for compressing 4 Ch X WD1 X 30FPS is the same for 1 Ch X1080P X30FPS. The DVR may carry the CPU or IP camera may carry the CPU inside. As said above, if he can pay around U$10 more, he can have a brand new stand alone DVR, for sure. SD card is good for the back up, not good, not stable, not durable for main, at least to me. It's all up to him which way to go. He wants to have ALL for U$100.

Many chances, where 4 Cheap Cameras are better than a single expensive camera, just in case losing one camera as a failure, working 7/24 day and night.

Mystang, Good Job you Did. The system could be 16 Ch CIF Based Recording, as you say 15 years old stuff and video card or something. The video resolution seems to be outdated as Too Small in a current CCTV trend. The cameras must be all analog NTSC or PAL cameras. You can, for sure, have the D1 or 960H resolution(4 times of CIF resolution) for each camera. Save all cameras working. Those seem to be good ones, no trouble for the last 15 years. Save all HDDs working, good if powered enough. Buy a new stand alone DVR (WD1 or 960H : Recording and Preview X 16 CHX 30FPS Realtime). It could be less than U$ 200, please check them out on internet. If you go for HD-TVI type, you can enjoy a lot better resolution. But you need to buy new cameras and new DVR and HDDS: The DVR could be expensive. I do not think there is any product, capable of FHD(1080P)-16Ch X 30FPS each Recording / and Previewing/ Playbacking, 16Ch simultaenously. There are some DVRs limited to Playbacking 4 Channels at a time, while recording 16 Ch. It's upto you.

Search at alibaba.com or aliexpress.com Get 4Ch PC Capture DVR Card around U$10~15. Do not buy USB-DVR kinds of stuff which do not provide D1 X4Ch X30FPS, at all. The PCI capture card is to provide 4Ch X D1/960H Recording and Preview at 30FPS realtime. Its software allows a remote access for your smart phone. Then buy analog cameras ranging U$10~20, each. You do not need to pay more than U$20 each. You need to bring your OLD PC, HDD, and Monitor, available. If you have a used HDD available, you may buy a standalone DVR for 4Ch X D1/WD1 recording, ranging U$30, in stead of PC DVR capture card.

Key issue is the cabling distance. High Frequency Components of HD Video Content gets mostly affected/deteriorated as the cabling becomes longer. That results in Video Loss (Failure to Capture Video) or Softened Video(bad contrast, poor video quality). And Electric Power of DC (direct current) for cameras can not go that far. Balun is just re-shaping up high frequency band. Do not place much of expectation on Baluns. Cable quality should come as first priority. Subhakar, the success of this project seems to be very crucial for the engineering groups who invented methods of transmitting HD video contents in a conventional amplitude modulation, that is, HD-CVI (Daihua), HD-TVI (Hikvision, Techpoint, and others), and HD-AHD (Nextchip.com). As you go for HD-AHD, you better ask some tech supports or guide lines from Nextchip.com. Finally you may please post the status or success story of this project that many forum members are to appreciate.

You may check techpointinc.com who supplies HD-TVI chip set to DVR makers.

AHD is invented by NextChip.com. 800 meter is quite challenging. You better get some advices from nextchip, before launching the project.

Yes, Analog is the cheapest and simplest. If one NTSC analog camera output is to be displayed on a single monitor, the CVBS -NTSC resolution might be look too much soft on a single monitor. As the cable distance can not be an issue, I would recommend HD-TVI or HD-CVI or HD-AHD system. These system is becoming as cheap as Analog system's. You can buy 4 cameras in one type (TVI, orCVI, or AHD) and Buy 5 DVRs of the same type. 4 DVRs are for dsiplaying 4 cameras, each 4 monitor. The one DVR is used to display 4 cameras on the 5th monitor. You can store the video data as well at the 5th DVR. You need 4 signal splitters-very simple, T type splitter. Even though the camera output is halved, the backend DVR can capture and decode the signal without any problem. As monitors are supporting HD-1080P, go for HD1080P camera (one type of TVI/CVI/AHD). As you buy 5 DVRs, you can place 2 cameras for each room, if you can charge a bit more.

If possibly "avoidable", do not go for "wireless". Not stable. Storing compressed stream into SD Card can be regarded as a "Back Up", Not stable and Expensive for long term & large data. The one: http://www.costco.com/Lorex-8-Channel-I ... 53164.html Can be a good one: But Expensive. Check out their Cloud Service is Free. Users are getting crowded, then poor services. Another recommendation: Search 720P (1.3MP) Cameras -HD-TVI or HD- CVI or HD-AHD type and accompanied(paired) DVR (that is, HD-TVI, CVI, AHD types). These cameras and DVR are becoming as cheap as Analog systems. You can get one of these system, well under U$ 400, including cable & 2TB HDD. You may search around... By Default, the DVRs enable you to watch the live stream view or recorded stream over network on your smart phone.

One camera may not be enough to nail the rat down. You may add and put some mobile black boxes (very cheap), inside your car.
