monitored fire alarm system
Surveillance devices are often hidden in walls or ceilings, so look for any spots that appear to be spackled or recently concealed. However, with the decreasing size of surveillance equipment, illegal surveillance can be concealed virtually anywhere. Household objects such as pens, clocks, lamps and
even watches may contain devices to see and hear what you are doing. Closely examine your home's windows, as the exterior of windows are excellent places for installing illegal surveillance devices since no one has to break into your home to install them. Conduct “sweeps” of your home on a regular basis. Keep an eye out for any signs of a break in as well as any
strangers that come inside or even near your home.
