Can You Help Me Choose a Better DVR Card?
Thomas replied to gaz_0001's topic in DVR Cards and Software - PC Based Systems
Sounds like common sense but yet at the same time is about as far from reality as you can get. Differant factories and manufactors have differant QC standards and use differant suppliers. -
motion alert via SMS text message to cell phone?
Thomas replied to ncpilot's topic in DVR Cards and Software - PC Based Systems
It's doable. The problem becomes getting the site parsed to use your method. But you're kinda overworking the problem. Most cells will accept e-mail as a text message. @. will usually work. -
Some of it will depend on the camera and signal strength. My understanding is that it's a three 3db loss everytime you change connectors.

FRAMES PER SECOND VS. IMAGES P.S. VS. PICTURES P.S. VS FIELD
Thomas replied to ronster's topic in Digital Video Recorders
They all discribe one of two effects: The complete viewable image: 30 Frames per second One pass of internlaced scan lines (or one half of a full picture): 60 fields per second. The general rule of thumb I would use is that if they don't say frames per second, I would skip them due to being shady. -
Where to find looong camera mount, like 2 meters/7 feet?
Thomas replied to dantheman's topic in Installation Help and Accessories
The deterant effect is non-existant. People generally just tune them out after a while. -
Video Insight vs. Geovision
Thomas replied to securitymonster's topic in DVR Cards and Software - PC Based Systems
It makes it easier to work with access control systems for intergrators. And all cameras use the same port. (Noting they can all be streamed at the same time, it's just all traffic on port 4000) -
Video Insight vs. Geovision
Thomas replied to securitymonster's topic in DVR Cards and Software - PC Based Systems
My understanding is that it's streaming it via our normal port for internal streaming rather then defining a camera to a port. I can ask the developers if you would like. It should define the camera number as one of the connections. (Note that while I have a techincal background in both hardware and networking, I am not a programer. I'ved looked at some of the SDK info but if you're looking for code examples I am not the right person. ) However with the example you're looking state, I can do something simular without the SDK. http://www.demovi.com/videoinsight/Pages/Camera.aspx?ServerID=1&CameraNumber=1 That URL would allow for an embeded view in an I-Frame on a site. Server ID is set by the server and the camera number comes from the server. So ServerID=6&CameraNumber=18 would be the 18th camera on Server 6. If you want clarification on the ports question, let me know and I'll ask development -
Video Insight vs. Geovision
Thomas replied to securitymonster's topic in DVR Cards and Software - PC Based Systems
I'll be happy to answer direct questions about our product but I'd perfer not to do a comparison. I try not to do sales stuff on here and that kinda crosses the line for me. -
Haven't played with the card before so I can't judge the quality. LSI is a middle tier company as far as averages go. Depends on how smart the card is but two arrays generally takes two cards. It's going to take a PCI slot and the drives will connect directly to it. Usually it does a BIOS hook to let you do the set up prior to OS boot and it should have a driver disk. Which you will need if you do the OS on an array.

Wireless analog is broadcast as a waveform. There is no binary converison.

Wireless IP Camera interference question.
Thomas replied to LittleScoobyMaster's topic in IP/Megapixel Cameras and Software Solutions
Does Geovision have support for IP yet? I know I heard about them talking about it but I haven't seen any IP Camera support yet. -
Ok, New camera Mounted.....need opinions please.
Thomas replied to DeathtoToasters1's topic in Security Cameras
I haven't run into any of the manufacturers who won't give the protocols. The only troubles I've ever seen were with some of the older protocols that thier support people didn't have on hand. -
Publishing "dealer" pricing on a site?
Thomas replied to madcrabber's topic in General Digital Discussion
My general thoughts is that end users seeing anything other then MAP on a site is bad. If they get a lower quote from calling in, that's fine. -
Publishing "dealer" pricing on a site?
Thomas replied to madcrabber's topic in General Digital Discussion
Price fixing is illegal. But at the same time a manufacturer can make it unpleasant for those who bend certain marketing guidelines. And companies don't care if you sell thier cameras at 10% below MSRP or MAP. What they care about is one person not destroying distrubtion channels. Look at Geovision. I talk to dealers that are finding it harder and harder to make money on them because of all of the sites who push thier cards at cutthroat prices. Even if they wanted to, it's really hard to close Pandora's box when it's been opened. -
Night Clubs - dvr suggestions? Night vs. Day codecs?
Thomas replied to TopGeek's topic in General Digital Discussion
Yep. Keyframes tend to be bigger then individual MJPEG frames. But the savings from the other frames make up for it. -
Night Clubs - dvr suggestions? Night vs. Day codecs?
Thomas replied to TopGeek's topic in General Digital Discussion
This is going to sound counter intutive for a lot of people, but MJPEG will give you a smaller file size in rapidly changing condisions. MPEG based recording is not very good at rapid lighting changes. The image is fine but the file size balloons out of control. -

Does Dubai have a firewall like Saudi Arabia or China? Do you have a static or fixed IP address?

The PCI bus is the current bottleneck. It's why you don't see non-hardware compression 480 cards.

Need help understanding DVR archiving & backup methods
Thomas replied to pbogi's topic in Digital Video Recorders
It sounds like you are discribing motion based recording? Most systems have a record aways option and then a triplex DVR should be able to just burn/move the files at the users command. -
The differance is a star vs loop topology. While both systems will have a choke point at someplace, the differance is that cable's choke point is at a neighborhood level rather then the ISP level. So yes, heavy traffic in a neigbhood can cause cable speeds and latency to drop. The capacity of a single neighboorhood loop is much lower then that of most COs.

Given the sheer numbers, I would be looking at multiple machines for IP or analog. It's simply too much to depend on a single machine. And for the record, the best layout is a 3x3 view. Casinos spent alot of time and money researching it.
