DVR Cards Pros & Cons
Thomas replied to MetzLyov's topic in DVR Cards and Software - PC Based Systems
Geovision doesn't make thier cards. UDP makes them. -
What size in MB is that 1600*1200 image? Because I can see four mins of motion adding up to alot of size. Now you might be able to use the iPod hard drives, but that's going to drive up the price quickly. But there are other issues, like focusing the lens when it's in place. You also lose all remote viewing. You lose any kind of searching features. You have to check the camera manually for each picture. You have to change out the drives when they fill up....the list goes on.

There are other limitations on image quality then the capture card. Cameras native resolution, lens quaility, ect. And you math is well off at least for some cards. At the software level we get three bytes per frame, not two. The digital stream is coming in as YUV or RGB vaules. So you get: 720*576*3*25= 29.66 Mbytes/sec per channel. Multiply that by 16 channels and you end up with 474 Mbytes/sec. The reason for not using digital cameras is three fold. One is that no one has a standard interface. Even within the same company the cameras don't have a standard interface. So you have to code for each one. Second is that most digital cameras compress down to 320*240 or 640*480 to save bandwith over a network. And third, what format is the camera going to give you? JPEG? JPEG2000, RAW? The last one creates headaches because .RAW is just an extention, all raw file formats are differant on all of those high end cameras. Other reasons not to grab stills. Unless you are taking a really rapid stream of stills, you will have time gaps of a second or two. If you are taking a rapid sersis of stills then you might as well be taking video.

He won't be port forwarding but port forwarding/remaping. In a Linksys router you set forwarding on 80 and it just passes through traffic on 80. In this case the router would be moving it from 80 to 8080 along the way. -
PPPoE is Point to Point Protocol over Ethernet. Or Dial up over ethernet. It's what most (not all) DSL lines use. Thier software is most likely a PPPoE Dialer. Most routers let you configure those settings and will keep the connection open.
-
The router would need to be set most likely to PPPoE or PPPoA.

Recovering overwriten data is possible. But it's also expensive. Whenever you write to a drive, you change the electron patterns. And those patterns tend to stay. If the platter is viewed with an electron microscope, it can be possible to "read" overwriten files. But this requires a few things to work. One is a clean room. The other is an electron microscope. Neither is cheap. But if you google it you can find companies that offer this service.

It almost sounds like they are using VNC.

Looking for card/software.
Thomas replied to Marcusl's topic in DVR Cards and Software - PC Based Systems
But you can enforce MAP (minimum advertised pricing). Only on the card and software. Once a dealer puts it in a machine, I can't enforce what he says the price is. Now I can do my best to discourage that practice but the tools I have to do it are extremely limited. I'm not saying that Geovision's practices are good for the industry, or good for installers. I'm not saying I approve of their bussiness practices. I'm simply pointing out that the options to actully do anything about it are limited. -

Just to nitpick, but MSRP's are not enforcable. I can not require a dealer to sell at a set price. Nor can Geovision. If someone wants to try to get by on a 10% markup then it's their right. If I attempt to retailate punitively (reducing thier discount, ect) then I would be invoilation of price fixing laws. -

It's going to depend on the router. -
A few things. 1. You can't buy retail because the only form out has been in beta. The retail release hasn't occured yet. 2. There will be a stand alone version. Given the structural differance, I wouldn't upgrade but use a clean install. 3. The buggyness is tied to the driver issue. 4. As much as I dislike MS, they haven't sunk so low as to charge for support with a beta product. For now Rory, there are very few advanatages to using a 64 bit chip, except that manfacutres are shipping them at higher clock speeds. NX support is presant in thier 32 bit cousins, you won't get a speed boost for most apps, even if it's been coded for 64 bit. Bussinesses have had access to 64 bit hardware since before Linux was a gleam in Linus's eye. *BSD's have had 64 bit support for various infrastructures. Sun has been more then willing to sell you 64 bits for a long time. So has IBM. As far as OS support goes, both Windows and Linux show dual core chips as two processors (or four if they have HT) in SMP mode.
-
Um, it depends on support and the OS. There are 64-bit versions of 2k3. But XP's 64 bit edition comes out in about a week.

Why is even tougher. Why is this address set at localhost, why is this the machine's IP address.
-
As much as I love a good tech document, it simply can't cover every situation. It should help with vanilla installs, it should help with more comman non-vanilla installs. But you can't cover every exotic situation.
-
UDP is the OEM for Geovision's cards.
-
Really good tech support is a dark, dark art.
-
I'm not running any DVR on ME. I've just serviced alot of them,
-
Win ME is very, very, very hardware dependant. On some machines, it's rock soild. On others, it's painfully unstable.
-
Also check to see if the modem itself has a firewall. The Westells that the baby bells seem fond of have them.
-
Hah! Breaking new toys is exactly how you learn how to get the best out of something.
-
It's a matter of perspective. Is it bad for you? No. If that $2000 is the dealers cost, is it bad for him? Yes.
-
*coughs* You don't remember when IBM was the evil empire of the tech world do you Rory?
-
Simply to allow Dealers to make a profit on items. There was spefic instance in which a customer went to a dealer from this forum, with dealer prices obtained from this forum and demanded that he be sold the items at cost. You can't make a living selling things at cost.

AUDIO! Anyone got GOOD REMOTE audio? Past more than live

Motion detection is going to be hard, but wait till you try the text insertion for time/date stamps.
