Timers and Sensors for Home Security

Timers

Timers are dependent on electricity to help them maintain the clock that drives their mechanism. By definition, timers are designed to turn the lights on and off at prescribed intervals. Their timing may be automatic, as in the case of spring-winding interval timers that power heat lamps or lights in restrooms and hallways. These timers can be very handy in bathrooms where lights are left on or where timed ventilation is needed.

Plug-located timers are common, inexpensive security measures. These units feature a clock that is set for on-off times, plugged directly into the wall socket, and used as the plug-in device for lamps, stereos, or televisions. Socket-located timers fit directly into the medium-base socket of an incandescent lamp. This timer will activate when the lamp is turned on and will automatically turn off after the designated time has elapsed. These timers are very inexpensive and easy to install, but make sure to follow the installation instructions if you do it yourself.
