It is now very affordable to secure your family with indoor or outdoor cameras.
Change the television channel to show live camera feed of your children at play in the yard. If your infra red outdoor camera watches the approach to your front entrance it can be set to record or notify you when motion is detected, however this unique system will not record incidental movement caused by the wind, you can set the motion detector to pick up a single point, say the centre of your front walkway, now recording will start only when motion is detected across that point.
Indoor color cameras can be fixed or have pan, tilt, and zoom. They can be set to record or notify you of events. You can view live events from any device that is internet capable, including your office computer (PC or Mac), lap top, blackberry, and iPhone.
