"A free monitoring system via webcams."
Cerberus is a complete monitoring system via webcams, thanks to which you can control any part of your home, business, office, etc. The program allows up to ten cameras at once, each of them configurable separately.
Some of the best features of Cerberus are: get screenshots periodically, detect movement in the area of the webcam (in this case either record what's happening or send a warning email), etc.
Cerberus also offers endless extra options which significantly increase the functionality and versatility of the program. You can add logos or text to the shots taken, view them in the program itself, rotate the webcam image from one to another (where you have configured various), etc. Also, if you don't want to continuously record the same place, maybe because it takes too much time, you can indicate to Cerberus to be alert, and start recording only when movement is detected.
