CCTV Camera LabView interface

[soliman]

Hi, i have 2 CCTV cameras which have their own program to preview, but how can I grab them on labview and what are the modules that i have to work with ??

can anyone give me an example vi for this ?

Well, first you need to determine what are the protocols the cameras work on. Then, we can figure out the best way to get you up and running. If you don't know the protocols, be sure to post a link to the specification documents of both cameras, and maybe we can help you from there.

OK it seems like it might be connected through serial based on the specifcations that you have provided. These seem like specifications for the card instead of the camera but I believe that's how you are interfacing with them. Now, what sort of software do you use to talk to the camera usually? Has there been provided by the company that sells those? Do you have link for the cameras and the card you are using?

it is 1/4 sharp camera and it is color ccd camera connected with a coaxial cable to the card

hope that is helpful

this is the offecial site of the card

I am not sure if you understand me correctly but what I am looking for is the exact spec document of the camera and the card that you are using. You cannot expect me to go through the website to find that information.

If you installed Vision Acquisition Software, you can check if your camera is listed in MAX under cameras category while it is connected.  If your camera appears there, then it will be available also for acquisition from LABVIEW.

That's NOT true. LabVIEW can connect to any instrument, you just need to know the protocol and figure out how to talk to it (if possible) through LabVIEW. The camera will not show up in Vision Acquisition Software if it communicates through a DLL or ActiveX interface. In any case, have a look at the release notes of the VAS. And, here is another important link: Industrial Camera Advisor.
