Motion Detectors
Motion detectors can be used in many different ways to help make your home more secure. It’s not enough just to protect 2 or 3 doors or windows with sensors. Homeowners should invest in a couple, if not several, motion detectors (depending on the size of your property) to ensure that your home is fully protected inside and out.
Some motion detectors are very simple and inexpensive, while others are more complex and somewhat more costly. Among some types of motion detectors are infrared, pet immune, dual technology, ceiling mount, and outdoor.
Most motion detectors are battery operated and don't require a direct power feed. However, it is very important to make sure that the batteries are always checked and replaced often.
For the most part, motion detectors work to cover various “zones” throughout your house and will trigger the alarm when it detects movement. But with some more advanced home alarm and surveillance systems, a motion detector can also control such things as hall, stairway, and outside lights, plus cameras.
Cameras controlled by motion detectors can save you memory storage, while motion detectors that control lights can save you energy. First, many up-to-date security systems rely on motion detectors to activate cameras. Because you are only recording when there is motion detected, this saves storage space on your VCR tape, DVR, or computer hard drive. Second, a homeowner can use motion detector lights. Again, the light only comes on when motion is detected, therefore saving you money on your electric bill.
