A wireless motion sensor alarm is a popular alarm systems installed in homes and offices. It is a device that is used to detect motion which then triggers an alarm. There are two types of wireless motion sensor alarm—the passive and the active motion sensors. Passive alarm systems detect motion within the field of view of its sensor, such as a close-circuit camera. It also detects movement by monitoring the changes in temperature in a specific area. An active alarm system, on the other hand, uses photo sensors, ultrasonic waves or radar. When the sensor sense a disruption on the signals that it emits, it then triggers an alarm. Having a wireless motion sensor alarm has a lot of benefits but it has some drawbacks as well.
Pros of Wireless Motion Sensor Alarm
A wireless motion sensor alarm is a portable device that is easy to dismantle and set-up. It does not need any wires which make it easy if you need to reposition your motion sensors into another area of your house or office. A wireless motion sensor alarm is also independent from the power grid of your house. Instead, it uses batteries for power. This means that even during blackouts, a wireless motion sensor alarm can still function.
Most wireless motion sensor alarms have advanced features, such as automatically dialing 911 when it detects unwanted entry, while other motion sensors alarms simply emit a loud, piercing noise that can be heard at long distances. A burglar cannot easily sabotage a wireless motion sensor alarm by cutting the wires connecting the sensor to the alarm since a wireless motion sensor alarm has no wires that could be cut.
Cons of Wireless Motion Sensor Alarm
Since a wireless motion sensor alarm uses batteries for power, you need to regularly check and replace the batteries in order for your motion sensor alarm to work. This can be a bit pesky since your motion sensor alarm will not work without batteries and if you forget to change the batteries your house or office will be vulnerable to unwanted entry.
A wireless motion sensor uses radio waves for communication between the sensor and the alarm. This means that each component of your motion alarm sensor must be within radio range of each or else the sensors will not be able to trigger an alarm. This can leave some areas of your house vulnerable to unwanted entry, which is especially true if you have a large house or office. Wireless motion sensor alarms are often placed at main entrances, leaving other probable entrance and exit areas unprotected.
When installing a wireless motion sensor alarm system it is best to take note of its disadvantages. Since wireless motion sensor alarms can cover only certain areas of your house it is best to install them in rooms where your valuable properties are kept, such as the vault area, your main bedroom or your home office.
