Pros and Cons of Motion Sensors

There are pros and cons to any home security device, including motion sensors. So let’s dig into what you should be considering when shopping for a new security system.

Wireless motion sensors (or motion detectors) detect motion and send a signal to the security hub, which then triggers an alarm if the alarm is in “away” mode. There are two types of wireless motion sensor alarms: active and passive.

Active motion sensors use photo sensors, ultrasonic wave or radars to detect motion. When the sensor senses a disruption on the signal it emits, it then triggers the alarm. Passive motions sensors are a bit more sophisticated. Using passive infrared (or PIP) technology, they can detect movement in any room. Having a wireless motion sensor as part of your alarm system has a lot of benefits but also some drawbacks.

Pros of Wireless Motion Sensor Alarm

A wireless motion sensor alarm is a portable device that is easy to 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 and power outages, a wireless motion sensor alarm is still functional.

BrightSuite Motion Sensors are designed to mount on any flat surface or in the corner of a room offering a variety of options for installation. Any motion sensor installed as part of BrightSuite is connected to a central hub to automatically notify you and our professional monitoring station of unexpected activity. Other motion sensors on the market may not be tied to the security system and, instead, 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; however, that same burglar could break any motion sensor that is only designed to emit noise thus rendering it’s effect useless. For this reason, it is important to find a motion sensor that wirelessly connects to a central monitoring hub in your home.

Another benefit of BrightSuite motion sensors is that they are pet friendly. Our motion sensors are “pet immune” for any animals up to 40 pounds. This is an important factor for many pet owners, so make sure to look out for this feature regardless of the motion sensor you choose.

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.

Fortunately, the BrightSuite security system notifies you when batteries need changing in your motion sensors giving you peace of mind that they will always be functioning properly. Additionally, all BrightSuite motion sensors contain advanced circuit technology resulting in ultra-low power consumption, allowing for multiple years of service before needing to replace the battery.

Many wireless motion sensors use 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.

BrightSuite motion sensors use a proprietary Encrypted Wireless Sensor technology to extend their range and ensure security and privacy. This ensures all BrightSuite motion sensors work within your home and stay connected to your central hub.

Regardless of which wireless motion sensor you choose, it’s best to be thoughtful of where they should be placed in your home. Since wireless motion sensor alarms can cover only certain areas of your house, it is best to install them in areas of your home that get a lot of foot traffic like an entryway, living room or kitchen. It is also a good idea to place a motion sensor in rooms where you keep valuables like your bedroom or home office.
