SightHound works fine with a USB Webcam. A good one from Microsoft or Logitech would cost between $20 and $60. I have 5 that I aim out windows to view the yard and street around my house.
The only problems with Webcams is that cheaper ones will tend to smear movement in dark scenes, and the drivers for most brands do not allow for multiple cameras of the same make/model.
Connecting two of the same model camera will often result in the scenes swapping position in SightHound or one camera will show in both camera positions. Eventually they will cause the Blue Screen of Death (BSoD) or a spontaneous reboot. Sometimes cause just a complete lockup where only a complete removal of power will get control again (even had to pull the battery on a laptop once! Holding down the power button for minutes did nothing!)
Only Logitech cameras claim (recently) that their drivers will handle multiple cameras at once. Though I have 2 Logitech C615 cameras that still interact with each other (if the scene is bright for one camera, it MIGHT affect the other one to darken the scene and make it too dark... newer versions of the drivers might have cured that, but my system is not on the internet and thus does not get updates easily.)
By the way, you can get powered extension (15-ft.) cables ($25 to $35) for USB that derive power from the USB port and can be daisy-chained up to 5 times, so a USB camera can be a long distance from the computer (I have one camera on the end of a set of 5 powered cables and a 3-ft unpowered extension and the 3-ft cable on the camera itself [over 81 ft.] and it works fine.) I have 4 other USB Webcams on shorter daisy-chain cables, too. All are Logitech brand, but a total of only 4 different models. The cheaper ones don't work well in low light, but the more expensive ones do a wee bit better (not great, but "better").
