Many homeowners have turned to using motion detectors as a way of providing safety to their family. These detectors are in the form out outdoor lighting that typically looks like any ordinary outside light fixture. The way they work is that you simply leave the on/off switch on and the light will go off in a few minutes. Then, while you sleep, if someone should come up to the house to try to get in, the light would automatically turn itself on, illuminating your home.
If you want more security for your home and family, you will find that installing a motion detector is easy in that many units on the market today are pre-wired and pre-assembled. All you need to do is replace an existing outdoor light fixture and in minutes, you will have added protection. The only drawback to a motion detector is that if you live somewhere, where wild animals come up to the house, or if you have trees that might sway during heavy wind, the light could be tripped.
The most important thing before you get started is to shut the power off at the breaker box. Additionally, make sure the wires are turned off by testing them. Put safety goggles and a dust mask on and then you are ready to get started. If there is an existing light fixture, you will need to remove it. Next, match the existing screw holes on the cover plate with the new junction box. In most cases, you can use a hammer and screwdriver to know them out if needed. Then, you want to caulk any open holes that will not be used to eliminate water leakage.
Next, take the fixture wires and thread them through the cover plate gasket, connecting them with the house wires. Be sure you connect the black wire to black, white wire to white, and if you have it, red wire to red. Secure the wires with wire nuts and then attach the junction box with screws.
Once the light fixture is in place, all you need to do is add motion detector bulbs, which can be purchased at your local hardware or home improvement store and you are ready to test the newly installed light. On the bottom of the motion detector, you will find a sensor switch and an adjustment dial. Put the slide in the test mode and then set the level of sensory about half way.
Now, go back to the breaker box and turn the power back on. With the wall switch on, you should see the light come on for about 30 to 45 seconds. Once you see the light come on, you can position the lights into the direction of the yard that you want covered. Typically, this would include a walkway up to the house or any direction that gives good coverage on the windows and doors.
During the testing process, if the light comes on but then goes off immediately, chances are the lights are directed too close to the sensor. To correct the problem, simply reposition the bulbs away from the sensor, generally about 1/2-inch distance. Now, all you need to do is again adjust the sensory level for what you want and slide the switch from the test position to where you want it. Now that you are done, you can sleep in peace.
