Frequently Asked Questions (FAQs)
1. Do motion detectors set off alarms?
Yes, motion detectors are designed to set off alarms when they detect an increase in infrared energy. This indicates that someone has approached the sensor or walked within its range. When the motion sensor detects this movement, it notifies the home security control panel, triggering an alarm.
2. What are the three types of motion detectors?
The three main types of motion detectors are optical motion sensors, infrared motion sensors, and radio wave motion sensors. These detectors are commonly used in security and safety lighting systems, occupancy sensors, and combined sensors. Each type operates differently and is suitable for various applications.
3. Are motion detectors worth it?
Yes, motion detectors are worth it for enhancing security and convenience. They are low maintenance, energy-efficient, and can be programmed for various functions like turning on lights. Motion detectors can be used to secure entry points and monitor movement in businesses, providing added security for employees and vendors.
4. What are the disadvantages of motion detectors?
Some disadvantages of motion detectors include the potential harmful effects of high-power radio frequency for humans (in active types), the inability of radio frequency in the microwave range to penetrate metal objects (in active types), and the limited operating temperature range for passive motion sensors (up to 35°C). These factors should be considered when choosing and installing motion detectors.
5. What interferes with motion detectors?
Several factors can interfere with motion detectors, including flying or crawling insects, pets, curtains or plants being blown by air conditioning or heaters, low batteries, and ceiling fans. Additionally, objects moving near the motion sensors can also trigger false alarms. These potential interferences should be taken into account when installing and positioning motion detectors.
