USB security cameras are both affordable and easy to install which makes them an ideal choice for security and surveillance monitoring both in the home and at the office, especially if you are not interested in buying a full system.  USB security cameras utilize a personal computer as part of the security system instead of a Digital Video Recorder or DVR.

“USB” is a computer acronym that stands for Universal Serial Bus.  These cameras require a coaxial cable or similar cabling for transmitting their video images to a processor or personal computer.  They do this via the personal computer’s USB plug.
