To a thief, a construction site can be a treasure trove of expensive tools and possibly an easy way to get into someone's house. Nightwatcher Security Lighting should thoroughly freak out even the most adept burglars and vandals. The lamp operates like a standard motion sensor light except that it doesn't just light up – it also points in the direction of the moving object and follows it for as long as it remains within a 60-foot range. The device has a turning radius of 220 degrees and installs with three wires, just like any light. Both halogen and LED models are available, and some units can record video.
