  A project I want to do is write a Labview application that would communicate to the Webcam USB and publication of the application in a secure web page, and allowing users to control Labview applications at home, work, and anywhere in the world without having installed on the PC of the Labview software. On the web, users can control the Labview front panel for zoom, annotations, etc. As a surveillance camera the USB Webcam will be detect an object moving, save images when motion was detected, an alarm to alert.

  I was wondering if anyone can help me with this.

  I have Labview Vision and I can get the USB Webcam streaming images.

  I don't know where to find information about the detection of a moving object.

  Can someone help me on this please?

  Hi krispiekream!

  I guess that your USB camera has the ability to zoom through a control programmatically? If not you should be able to control the camera using a remote facades, which require the LabVIEW runtime engine. Here's a tutorial on the remote Front Panel LV development of Applications: http://zone.ni.com/devzone/cda/tut/p/id/3277.

  With respect to the detection of a moving object, you can take two images and subtract to determine if there was movement in the frame.

  I hope this helps!

• Equium A60 does not recognize the USB webcam

  I just bought a creative vista more webcam and tried to install it on my laptop Equium A60, the software is installed properly and everything but when I connected the webcam to the usb port my laptop didn't recognize it.
  I tried to uninstall and reinstall and nothing has changed. Someone has an idea of what could be bad?

  Hello

  Sometimes USB devices can be recognized correctly because of the low power from USB ports. Usually, USB devices should work with 500mA of power. It is a standard. But sometimes the USB devices need more than only of 500mA. In this case, you can use an external USB hub with external power supply.

  You can also disable the power save option in the device under USB root hub Manager.
  You will find a power management tab. Please enter in this tab and disable the option: allow the computer to turn off this device to save power.

  D this on all the USB root hubs

• NB100 - how to adjust the brightness of the screen?

  Hi all.

  You just bought a NB100 - overall very very happy with it. Well built, good screen and very compact, etc.

  You have some questions? The brightness of the screen is controlled by the Fn + F9/F10. I love that she's set on ' to Midway ' or less - in part to preserve the battery - but also because I find max brightness is actually TOO bright for me! But the reboot of the machine always seems to start up. Is there a way around this? There may be a firmware update (my machine seems to run version 1.90 which I believe is the most recent)?

  I noticed other referring Fn + F8 discussions as a way to select Bluetooth/WiFi etc.? Mine seems to just control the setting of the fan and processor - fan speed "gray" setting gives clocked at 1.6 ghz and fan lights - while Fn + F8 activates / deactivates an icon fan 'white' - where the processor strangling up to 800/900 ish and the slows / stops (?) fan. [by the way I noticed some videos become "jerky" If you choose the lower setting]

  I'm not 100% sure what Fn key + "pipe" (to the left of the formula 1)? The Fn + F1 turns on without wireless/wifi I know - but the key of "pipe" seems to be a symbol of Wlan (or is it the key to use for Bluetooth or GPS or other)? Sorry to sound so ignorant - but the user guide does not in this detail. I'm pretty sure that the machine, I have bought - that was one handed to new/refurbished Toshiba NB100 - model PLL10E - did not all BT/GPS etc - just the basic wifi which F1 comes on and goes off.

  Last comment - and others have said - the main peaks are very difficult to see in the dark! The 'gray' color was definitely a design error! But I can live with that - either a usb light? or a few letters of stickon (white)?

  Greetings to all.

  Hi, I think the best way to adjust the brightness is in the options of the properties of the energy available in the system tray icon. I don't know about the activation of bt and wlan, it seems that bt and WiFi devices are on the same circuit power, so not adjustable. Nb100 is a good inexspansive machine :)

  They installed drivers for devices from Windows 7 for your make and model. If this is not the case, then go to the support web site factory and download Windows 7 drivers to a folder on your PC and then first install the drivers for the card mother/chipset, followed by USB, SATA, LAN, Audio and all other pilots.

• Adjust the brightness of the keyboard of the computer instead of the keyboard?

  Yesterday, I spilled some coffee on my keyboard and the computer works well, but my keyboard does not work.  I bought a wireless keyboard to use and it works perfectly, except that the keyboard of my laptop backlight is always on.  I can't figure out how to turn off without using the f5 and f6, keys that don't work on the laptop, so how can I disable this light without using the keyboard?  F5 and f6 don't work on the original keyboard at all, and on the outside, they do not work to adjust the brightness.

  Try this:

  Go to system-> keyboard Preferences, and in the keyboard tab, disable(uncheck) automatically "illuminate the keyboard in the dark.

• How to adjust the brightness of a video clip?

  Hello

  Using the latest iOS on iPhone6s with the latest version of iMovie.

  I could not find how to adjust the brightness of a video I import to iMovie, it is quite dark and I want to increase the brightness or exposure.

  Thank you

  Greetings aytekdorken,

  Thank you for using communities Support from Apple!

  I understand that you want to adjust the brightness of a clip in iMovie for iOS. You cannot adjust the brightness directly, but you can add a filter to a clip or project that could potentially illuminate it for you.

• Not ' on' button pressed, then press on + or - keys to adjust the brightness of the screen on HP10BII +?

  Not ' on' button pressed, then press on + or - keys to adjust the brightness of the screen on HP10BII +?

  Just got a new unit, and one of the first things after how to turn it on, in the getting started manual, it's that if we push the button 'On' and then hit the + or - less buttons, it adjusts the brightness of the screen. On my 10BII + does nothing... so I wonder if I have a defective new out of the box. So far, all the rest, seems to work.

  Thanks in advance for everyone would be can confirm it should work.

  I can confirm that the 10BII + adjusting the contrast has very little effect.

  When you look at the screen at a low angle, the number "off" and the lights can be seen to slightly increase & decrease the contrast.

  For normal use, the contrast setting has no useful effect.

• Impossible to add an external monitor or adjust the brightness of the screen: Pavilion dv7-4031TX (Windows 7)

  Hello

  I recently replaced both hard drives of HDD2K12, which meant I had to re-enstall Windows 7. Since that time, I have no options more in using an external monitor or even the brightness of the screen. The computer does not recognize the monitor when I Plug and all my drivers are up to date.

  Can you make suggestions that could help to solve these two problems?

  Kind regards

  Peter

  Thanks to find the links but I could not find the drivers I need for a Pavilion dv7-4031TX.

  However I finally managed to fix the problem. Let me summarize what has been my problem.

  (1) I could not adjust the brightness of the screen by using the function keys f2 and f3.

  (2) I couldn't find the brightness slider if it was generally... i.e. (control Panel\Hardware and Options of Sound\Power)

  (3) my laptop would not recognize an external monitor.

  How I solved the problem:

  1 > pass.

  http://h10025.www1.HP.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-95107-1 & CC = in the & DLC = in & LC = on & os = 4063 & Product = 4253423 & sw_lang =

  and go to the graphics driver and download the graphics driver and follow the directions. At the end of the installation you will be asked to restart the computer.

  0nce you have restarted your computer, you should be able to adjust the brightness of the screen using the fn keys or the brightness slider in the window 'power Option '.

  2 > Activting 2nd monitor

  Click on Device Manager... At start-> right click on 'Computer' and click 'properties '. Click on "Device Manager". Now click on "monitors".

  Now connect the exernal monitor to your laptop while watching where the monitor icon appears under "monitors". It should appear as 'Generic PNP monitor'.

  Now, right-click on it and select "update driver software... "then search automatically for updated drivers. Install the new drivers. You should see the generic 'PNP monitor' name change to another name.

  3 > restart your computer. You should find that after doing all this, you should be back to normal.
