Their 4 camera DVR systems are going pretty cheap these days. For the $500 or so , you can have piece of mind...I have two separate systems installed at my shop. One for indoors, one for outdoors, one of them to the regular security system the other a freestanding unit just so I do not have to walk all 2 acres and 10,000sq/ft constantly during the course of my work day.
