Motion detection is an essential element in the improvement of residential security. Therefore, if you are interested in boosting the protection against burglars and robbers, you should consider setting up an intrusion detection system. In general, this type of product is designed to sense intruders in the house. The detector will send a signal and trigger the alarm or send an alert. Also, some sensor systems can be connected to a camera. If you are purchasing this type of security device for the first time, you might find the range of products confusing. Therefore, consider this brief discussion on the most beneficial forms of intrusion detection systems.
The popularity of passive infrared sensors in the home can be attributed to their relatively low cost. Also, they provide reliable functionality in intrusion detection, and they will provide long-term service. In general, these units do not produce energy for detection. Instead, the devices are designed to detect changes in temperature. Typically, the sensor will be triggered if the device identifies body temperature instead of room temperature in the surrounding area. These units are perfect for keeping your home safe when you are away from home or asleep.
Vibration detectors are also known as inertia sensors. As implied, these are designed to detect vibration which is caused by movement during an intrusion. These types of products are designed for installation on barriers such as fences, gates and windows. The primary objective of these units is to identify an attack on these structures. The design of the device relies on a specialised mechanical configuration with unstable elements. When the sensor is shaken due to the motions of an attack, the electrical circuits in the unstable sensor will be disrupted, and an alarm will be triggered.
Microwave detectors are favoured in the residential environment because they are sensitive to motion. A typical sensor of this nature relies on microwaves which are sent from the device. If a person passes within the field of the waves, they will cause an abnormal reflection of the invisible light. In some cases, the microwave intensity will reduce. These changes will indicate that there is an alien object in the room, and an alarm will be triggered. You should note that infrared and microwave detectors are susceptible to false alarms due to their sensitivity. If you would like to ensure accuracy, consider using both in tandem.
There are other numerous intrusion detectors to consider for your home. Therefore, you should consult a security systems expert for guidance.Share
