Here Is What You Need to Learn About Motion Sensors for Your Security System

Motion sensors are a critical component of your home's security system. However, not many people outside the security systems industry have enough knowledge of these systems. Essentially, motion sensors detect an intruder's movements and send signals to the control panel for risk assessment. The intelligent control panel responds by triggering or suppressing an alarm depending on the nature of the signal. In this way, the system mitigates false alarms while ensuring that your perimeter remains secure. Read the following information to get all the insight you need on motion sensors for your security system:

Motion Sensor Types

There are different types of motion sensors to suit your specific security needs. They are available as active sensors that emit ultrasonic waves of sound over the area you are protecting. In case of any interference of the radiating sound waves, the sensor sends signals to the control panel before triggering an alarm. Active sensors are also known as radar-based sensors. Secondly, you can opt for a cost-effective and user-friendly passive infrared motion detector. These sensors monitor the infrared energy radiated by human and animal bodies. Since this heat differs from that of the surrounding area, the sensor can detect an intruder and trigger the right response from the control panel.

You also have the option of a photosensor that works as an active motion sensor. The only difference is that the photosensor uses light instead of sound waves. The alarm will go off if an intruder disrupts the flow of light energy radiated by the sensor.

Combating False Alarms

The last thing you want is a false alarm from your security system. It is a nuisance and a distraction for the days you will have to respond to a real hazard. Thankfully, modern security system providers are good at combating false alarms from your system. The most reliable way is to have dual motion detection technology. For example, a passive infrared detector can be paired with microwave sensors to enhance accuracy. You can also bring in pet-immune sensors capable of ignoring an animal up to a particular weight.

Installation Takeaways

The installation also plays a critical role in your security system's accuracy. Some of the tips to use here include fitting passive infrared sensors ten to fifteen feet away from items radiating heat. Secondly, install the motion sensors to overlook access choke points (areas people must walk through). Hallways and staircases are good examples of choke points.
