Web cams have been a very popular item for us in our online store over the past year or so. People just seem to really love them. The thought of video conferencing with friends and family over the Internet for free or even just capturing some video or still shots is all very fun and exciting. Well, I think they are a blast as well. You can really have a lot of fun with them and with this week’s free download, we are going to tap into some more of the versatile Web cam attributes.

Web cams, as you may have noticed, are popping up all over. They are a great and inexpensive way to keep your eyes on things while you are away. With CatSpy (the download), you can take your Web cam and turn it into a motion detecting surveillance camera. That’s right, you heard me correctly. This thing is great. I have been playing with this software all morning, just running it through its paces and pushing it to the limit so to speak; and I have nothing but good things to report.

Basically, with CatSpy, you can turn any Web cam into a surveillance camera that will sit idle until motion is detected, where by, it will spring to life and start recording (per your settings). When the capture/surveillance is finished, CatSpy automatically saves all the video to a folder in your My Documents, My Videos folder for any later use. You’re not limited to one camera either. Say you have two or three cameras lying around. Well, just hook them up and CatSpy will take care of all of them for you. All you have to do is basically open up another surveillance window, point to the new camera;, make the changes to the settings if you need to and you’re good to go. You can connect as many cameras up to your PC as you want, but this is something that possibly will affect the performance of your computer and it may cause problems. This is especially true in older, less powerful computers, so do keep that in mind.

I will list the system requirements to CatSpy at the end of this article, but first, let’s take a look at the wonderful features CatSpy has.


CatSpy has been designed to meet some general purposes:

It uses a standard GUI interface without any customization to spare. The system resources for the real task are capture video and detect motion in it.


Motion Detection

Time Schedules

Active Area

Video Capture

System Requirements:



CatSpy will automatically install MFC (Microsoft Foundation Classes) and GDI+ in its private application folder.

One note on the operating system:

We strongly encourage you to use Windows XP, because it is the fastest operating system for this application. Both Windows ME and Windows 2000 lose a lot of processing time in their kernel modes (we do not know why), so Windows XP is the best solution.

Please refer to the Microsoft Web site to download the DirectX redistributables and the Windows Media 9 codecs.

This program is great. I just can’t say enough about it and I didn’t even tell you the coolest part yet. If you know how to access a remote computer (Remote Desktop), you can view your surveillance camera and captured video over the Web. Now, that’s pretty cool! I hope you enjoy CatSpy. I know I will be using it for some time to come!
