Set up three secret spy trackers, draw a map on your control panel showing where each one is, and you will know where and when intruders (e.g., little sisters or parents) have entered the secured zone. That is the idea of the Spy Tracker System, and for the most part it works as advertised. The trackers are easily set up, an erasable marker is included to draw a diagram of each sensor’s location, and the alarm can be set go off out loud or silently. The only real weak point is that the sensors don’t always transmit through walls. Requires eight AAA batteries (included).--David Stoesz
