WebcamViewer – View your webcam on Window 7

If you ever use Window XP + Webcam, you probably know that you can view the webcam under My Computer, without any application or webcam software.



Unfortunately, under Window Vista and Window 7, this feature has been removed, and if you want to have a view on your webcam, you will need a webcam software. Therefore I decide to develop a very simple webcam software called WebcamViewer that enable you to have a view on your webcam. You can download the software from the link at the bottom of this post.

image WebcamViewer is a very simple click-and-run application, where you don’t have to install the application. Simply download the exe file and run the exe file to use the software. You can store it inside your harddisk or you can carry it in your pendrive, and run it on any PC you want.

The Interface is simple, the first thing you have to do is to choose your Webcam. At the top left of the interface, choose the appropriate webcam. Please take note that some user might experience having “Google Camera Adapter” under the list, which is not the real webcam, choose the correct one.


After choosing the webcam, you will need to choose the desire resolution and refresh rate for the webcam. Click on the list at the right side of the webcam selector to view the available resolution and refresh rate for the selected webcam. For example “640x480 30” means that the width of the image is 640 pixel, the height of the image is 480 pixel and the refresh rate of the image is 30 frame per second. Please take note that the available resolution and refresh rate will be different for different model of webcam.


Now, click Connect, and you should have the live video from your webcam.

www.bustatech.com006 To disconnect, simply click Disconnect button or you can click the X at the top right of the window to close the application. To capture an image from your webcam, you can simply double click on the image, and the captured image will be store at the same directory as the exe file. A folder with the name of the webcam (Integrated Webcam in my PC) will be created at the directory of the exe file.image All the captured image will be stored in the “Integrated Webcam” folder, and the filename will be the date and time of the capture.image You can also use WebcamViewer to view more than one webcam at the same time. Simply run 2 copy of WebcamViewer (after having WebcamViewer running, simply double-click on the WebcamViewer.exe file AGAIN to have the 2nd copy of the application), and connect to different webcam on each copy of WebcamViewer.

I will report when I get a win7-friendly cam (grr), until then it will sit in it’s own folder on my d.t. Looks cool tho ;) j

hans heijhuurs

thanx very much, tried ten, so far yours wins easily


hello, i cant find a way to contact you via email, but i was wondering how far away a v2 of this great lil app is, because for the systems ive tried it on, it cycles on memory usage, so it will use all available memory, even on a 12gb system itll take over 10gb of it and then cycle back down and roll slowly upwards again, in 5 minute cycles, so that other programs dont have memory to use. thanks again, i look forward to a future version where it just uses a moderate amount of memory…


Great little program, lets me check my webcam and even allows me to take a picture. Who can ask for more?

Well, one can ask for more, but then the program wouldn’t be 180K. Love it. :D


I couldn’t find an application quite like as simple as this anywhere else. However the memory consumption is a problem. Is there a paid version that doesn’t have such an issue? I don’t need more features just something slim, simple, low footprint and will be easy to deploy to several hundred people. Please contact me if there is a paid version or a bounty to create this bug fix.


Hi, thank you for the comment. We noticed about the memory issue. Will try to improve that on the next version. Thank you.


Hi, I keep getting the message “Cannot connect device. The device may be in use” I have no other programs that use a webcam. Win7, 1.5 year old Dell desktop, if I try all the different resolutions it will finally connect, how can I connect the viewer to the webcam right away?


Hi, I have been having an issue with the video feed freezing or skipping running on my Windows 7 – 32 bit system. Is there any suggestings for how to fix this?


Excellent stuff – Many thanks. Can’t believe MS removed that useful bit of software from Win 7.


Best thing out there.


Two enhancements:
– Would be great if you could add a “full screen” button.
– Resolution of 1024/768 is also nice to have. Most beamers support this.

Wow that’s very useful and easy to use it, but i need to improvement adding for the sound features. Thanks. d(‘_^ o)

Hi, nice aplication!
Can I ask you what kind of dll have used to get webcam?
I have developed an application that should intercept the web cam and instead remains a black screen.
Your application instead work very well.
I have used C# and avicap32.dll, and you?

Software works great, but I need a hands off launcher for this program. I want to be able to start your program from the command line , have it automatically connect to a camera and position the view window at a specific place on the screen. For example with parameters instead of button clicks, for example:
WebcamViewer.exe -c1 -s2 -x100 -y50

where with the above parameters the program will automatically connect when started to the first camera in the list, at the size specified by the second choice in the second drop down box, and the view window is positioned at (100,50) of the screen.

Well done! Nice little utility. I miss that cam feature from XP.
You’ve gotten some good feature suggestions, like the command line params, and I ‘d like to suggest the ability to take a capture by pressing a key in addition to the double click thing.
But what I’m really post to ask you is if you would consider releasing the source code for this app!

hi, i have a problem when trying to capture a photo because it says ‘unable to create a file’ help please. Thanks

Alan Emmott

Hope this works


Perfect little programm, thank you!

YK Loh

Great little viewer with ability to capture and save still image.
However it would be even better, if the program be updated to capture and save video as well…
Guess this will then be a complete app.

Alan Westlake

The only webcam viewer i’ve found that works on my macbook running bootcamp and windows7. Do you mind publishing the source code for this?


Hi ! Found this with Google.
Just what I needed to focus a baulky new Kinobo USB B3 HD webcam whose free utility software refreshed the preview image *too slowly* under Win 8.1u1 to enable precise manual focussing.
Thanks to you, it is ‘Job Done’ !!

angel chuc

yo tengo la camara en mi laptop, antes funcionaba bien, pero mi laptop fallo y cundo me la devolvieron de arreglar, la camara web, ya no funcionaba, me entra la aplicacion pero no dice: bisomcam, ni las resoluciones, en fin ya no me funciona…


Excellent! Thank you!


Great app for basic webcam testing.

I’m noticing the memory cycling also. Normally it’s taking about 400M but if you minimise it or take away focus it goes into this runaway mode where it uses all available memory. Not really an issue if you’re using the app for it’s intended purpose.


Can’t find any stored images – at the same folder of this application – or anywhere! Any clues ?


Can’t find the stored pix – – any clue?


i have installed new window 7 and cannot instal webcame viewer softwear and when i try to intall framenetwork softwear message shown that already installed as part of your os.but my came is not working on dell lattitude d620

Vincent Dent

It would b nice to b able to send video strait to the cloud


Thanks very much for this, can now use my $3 Dollarama Tech1 web camera on old laptop. Could not make it work any other way.

Rick Stone

What would be nice is if there were a way to simply present the video in a frame without seeing anything other than the video.

Additionally, allow just rescaling the video to fit the frame size.


This is a great little program. I use this to monitor video sent from a wireless spycam mounted on a robot. The camera receiver is connected to an easycap and viewed with WebcamViewer.

Thanks for this handy, lightweight tool.


This is a nice and useful start.

Feature requests for v1.0.0.0: add settings for location of captured file (putting it in a folder next to the binary is a terrible idea on my setup) and for muting the sound.

Thank you!
