Also two people are not a consensus. It doesn't bother me if the forum stays public and in fact I would perfer it be open to lurkers.

Become a software developer and they will find you.

Not compatiable for OSX. Also a discontinued product. Please follow the links in the article next time.

They make Geovision's cards.

First, HTML isn't code. It isn't translated into any kind of binary nor does it compile into anything. It's simply a markup language. It is to code as .pdfs are to excutables. Now to stop being pedantic. Simple HTML will almost always render the same way. But once you move into the realm of CSS/JS/XHTML/etc...then each rendering engine will give you slightly differant results. Practical real world example: Try our demo page ( www.demovi.com ) in Firefox. It works. Now try it in Knoquer. It doesn't work as well. The problem being in Knoq's rendering engine. It's slow when you combine jpegs and JS. I suspect this will be fixed when they get all of the Safari fixes backported. That's a simple combination using common elements. Once you start talking about CSS you run into the pitfalls of no one supporting all of it. Simple C and C++ should generally work on any platform but even then differant compilers can give differant results. Add in quirks of the OS and trying to get at the networking stack, how differant systems handle permissions, etc and you will have to do some work porting it. If it's straight C then it shouldn't be a huge deal. But a big deal in a complicated program can take hundred of developer hours. And then we run into GUI elements. Unless you code them all yourself you'll be using some sort of toolkit. QT is cross platform but not always friendly. And the last step, supporting multiple OSs. Not fun, not easy and not cheap.

150 IR cams + 3 PTZ - is 3 computers enough ?

We could do it with five machines. One 32 channel card per machine and network them together. -
It depends on the clicking noise, I've most often found that the cause of clicking is rust on the platter. The simple test for this is to take the drive and stick it in the freezer for a few hours (put it in a ziplock bag and get as much air out as you can) and see if that makes a differance. The cold causes the drive platters to shrink just a little, usually enough for the heads to pass over the platter.

ActiveX Controls are windows only. Macs can not use an ActiveX control. ActiveX is a shell for an installer and requires API's that are only found in Windows. It's possible to write code that runs on Unix/Linux/Mac/Windows but only in theory. Even writing in C you will need to tweak the code for each OS.

Depends but you won't get a great framerate.

Ghost can make a self extracting image in an .exe.

VPN or Lan between the two locations? Any Existing fiber?

Punch holes in this please
Thomas replied to woodyads's topic in IP/Megapixel Cameras and Software Solutions
I've worked with guys who do IP camera networks and do them well and one of the common threads between them is putting them on a seperate network with the DVR/NVR acting as a gateway between them. To me that just makes more sense. They tend to be bandwith hungry and with all of the things being added to networks at the moment I wouldn't add that kind of load for 60 or 80 cameras. -
The percentage of jump capable SAR guys is pretty small. I know alot of people are shocked, but keep some things in mind. NO has a population of 1.8 million. Assume 2/3 got out of the city, or are on thier way out. That leaves 600,000 people still there. Most people need about four pounds worth of food and water per day. (Mostly water, remember there is no drinkable water there that isn't bottled.) That is 2.4 million pounds of stuff, per day. You can airlift most of that in and probley convoy the rest. Great. Now we enter the second stage. How do I get food/water/ect to the people there. That takes trucks, people and a centeral spot. For these you need fuel and communications. Now I've been hearing reports of the NG dropping off water but doing so at speed. My guess is they don't have enough troops right now to drop off/dispurse the water in a controlled fasion.

Living somewhat near by I can explain why you don't see much relief going on. 1. Access. New Orleans isn't very accessable at the moment. Roads in are flooded. The airport is trying to get a runway open and alot of the access roads are either underwater or damaged. Helocopters aren't very good for massive food/aid movement. 2. Danger. The city is pretty dangerous right now. They built on top of quicksand in essance. There is sewage/bodies/debrie in the water. Add in looters and you can't send in resuce workers in. 3. Communication. It's out in the city. Cell, landline are both out. Ham still works but they are running out of batteries. This isn't small scale disaster. NO is gone for at least three months, more likely for at least 9 before it can begin to start to return to normal.

I've been laid low with a bloody cold for the last few days after the show so this is why it's so late. This is just some random thoughts from the show. I was suprised at who wasn't there. Bosch, Sony....odd not to see them. Being by the booth with the drill bits has it's pluses and minuses. Being by CCTV Imports both also had it's pluses and minuses. They are a sexual harassment lawsuit waiting to happen. It's nice meeting the dealers that you work with. It's nicer when they give you tickets to the game that night. The asian guys in suits were all with card manufacturers. The white guys in suits were all venture capitalists. As many guys tried to sell me something as I tried to sell to others. This is just standing at the booth. Female salespersons have unfair advantages. It was alot smaller then I expected. I love seeing the gear that I would never get to play with in a million years. Throwable fire extingishers are just begging to be used in pranks by firefighters.

Yeah, just general script kiddies. Basicly little kids who have no idea what they are doing, but a get a little tool from IRC that scans for vunerable systems. And PHP is a absolute pain to secure properly.

Looks like they shared the same server for FTP/Web on IIS. Never a good idea. FTP should always be seperate from your web server. Shot in the dark but they had the root directory set up in FTP and the FTP portion was compromised.

Yes, they were "pwnd".

Is it possible to use a camera connected to DVR card as a
Thomas replied to Integratek's topic in DVR Cards and Software - PC Based Systems
You'd have find a way to feed it into a Twain driver. It's going to be tricky because you're going to generally have to encode it, then feed it back into a driver. Not going to be fun. -
0/1 * * * * /scripts/foo.sh 0/1 * * * * sleep 30 /scripts/foo.sh You can also call to a sleep script, but I seem to recall using the sleep command directly in crontab.

I could have sworn I saw ADT there. Not a huge booth, a 10 x 10 maybe. There were alot of China/taiwan/korea people there pushing differant products. Kinda felt bad for COPS-USA, they had a small booth next to ARM Electronics (stuff from the same factory), the differance being COPS-USA had a 10x10 booth and it looked like ARM did a large 20x20. And you had companies pushing neat toys like stun guns, or $50,000 PTZ's
-
I saw those, but I'm thinking they will be hard to get direct...where as I can see the throwable devices being picked up for offices. Bah, you don't sell my product so meeting you wasn't a highlight.

Bah, four blocks north, one west is a nice little shop that sells slices.
