Wireless Camera

[ReuvenGershon]

Hi. I have CVI2010 and i wrote a software that works well with usb-webcam. I can stream video and take ROI from it and by using pattern funcs. i can find the object. The question is i bought a usb video card and connected to it receiver of the wireless camera. Camera works well with it's software but when i try to use it with cvi the only thing i can see is black window.

Ps:

First camera ( web-cam) address was cam1 so for address i wrote cam2

Can anyone help me?

Hello,

Can you access your camera through MAX?

As your camera seems to be USB (because of its receiver) it must be DirectShow compatible in order to be accessed with IMAQdx.

If so, check the camera name in MAX and specify it in your program.

Is there an example of it?

Hi ReuvenGershon,

Measurement & Automation Explorer is National Instrument’s most basic way of communicating with devices.  It can be found in Start>>All Programs>>National Instruments>>Measurement & Automation Explorer.  Your camera should appear under My System>>Devices and Interfaces>>NI-IMAQdx Devices.  Have you been able to find out if your USB Wireless camera is Direct Show Compliant?

Regards,

Hi. I found the camera but still appears black screen. I am not sure if it is  Direct Show Compliant camera but as i told you before i am not using wireless usb cam. I bought a usb video card ( Syntek STK1160 ) and i connected the receiver to it.

Hi ReuvenGershon,

Where in Measurement & Automation Explorer does your camera appear?  Is it an IMAQ or IMAQdx device? When does the camera appear as a black screen?  Were you able to install any drivers with the Syntek STK1160?

Hi. It is IMAQdx device. When i click Snap or Grab it appears black screen.

Syntek STK1160 works with it's software.

In the tree of settings in MAX, you should see (if your device exposes them) a setting for configuring the video switch source (since I think your device might have more than one video input) as well as one for the analog format (PAL vs NTSC, for instance). You may need to play with these settings to make it work. The vendor software might be changing the default or auto-selecting it. Once you find settings that work in MAX you can then click the Save button and those settings will be used in LabVIEW as well.
