The intrusion alarm system can automatically detect intrusion behavior within the arming area. It effectively prevents theft and other incidents from occurring. Once an intrusion event such as theft or robbery occurs, it will generate an alarm signal. By using sound and light alarm signals to accurately display the location of the incident in the alarm monitoring center, the on duty personnel can directly see the area where the alarm occurred and quickly take emergency measures.

To maximize the effectiveness of the intrusion alarm system, the following three points should be noted when selecting and using it:

1 Selection and use of alarm control panels

• The main purpose of using alarm control panels is to prevent the occurrence of unexpected phenomena, so the automatic fault detection function of alarm control panels is still necessary to prevent the occurrence of false alarms.
• From the perspective of the working principle of the alarm control panel, the primary factor affecting normal operation is the power supply. The function of displaying the power of the uninterruptible backup power supply is abnormal and critical.
• It is very important for the alarm control panel to have the function of wireless forwarding of alarms when the landline is cut off or there is a malfunction.
• If the user is not on duty 24 hours a day, it is better for the alarm control panel to have remote monitoring function. If an intrusion alarm system has remote monitoring function, users can effectively disarm and arm at any time through landline and other means.

2 Selection of detectors

Choose detectors with special functions based on what kind of situations may occur.

• If the installation position of the detector is relatively low, in order to prevent anyone from intentionally spraying glue and blocking the detector, it is necessary to choose a detector that is resistant to glue spraying and blocking.
• If the installation position of the detector is relatively high, please pay attention to the selection of detectors that do not require frequent maintenance and upkeep.
• In tropical regions, due to high temperatures, some detectors need to be in an air-conditioned environment to function properly. Once illegal intruders intentionally damage air conditioning facilities, the detection range of general detectors will be greatly reduced, so intelligent detectors should be chosen.
• In some large places, there are many detectors installed, and if one or several of them fail, it will bring hidden dangers. When selecting detectors, it should be required to have stronger self-inspection function.

The situations mentioned above may vary in different situations, requiring users to choose detectors based on their own circumstances.

3 Installation environment of detectors

Reasonably select and configure detectors based on different monitoring environments.

• For the needs of wired and wireless functions, it is necessary to start from the user’s own environment and select the most suitable product. The flexible and concise characteristics of wireless intrusion alarm system is widely accepted, which can effectively avoid indoor decoration problems caused by the connection line between the detectors and the alarm control panel. The wired intrusion alarm system has many advantages, such as reliable communication, strong anti-interference ability, low cost, and so on.
• The main purpose of outdoor perimeter prevention is to prevent illegal intrusion of personnel. Due to the significant impact of environmental factors outdoors, false alarms often occur. Therefore, multiple detectors need to be selected for detection together, so that when one detector is affected by the environment, other detectors can maintain normal work. For example, when active infrared detector is affected by the sun, leaves, etc., microwave detectors can maintain normal operation. When microwave detectors are affected by electromagnetic and building effects, active infrared detector can work normally.
• In indoor monitoring, PIR motion sensors are generally used indoors, while wide-angle PIR motion sensors are used in larger areas. PIR curtain motion sensors should be used for windows and safety passages.
• Install detectors in some undecorated spaces, and also consider future decoration issues to prevent the influence of some decorations on the detectors.

Choosing different detectors for installation in different areas can maximize the functionality of the detectors. If there is no reasonable selection of equipment, it not only fails to achieve the effect of placement, but also wastes funds, and most importantly, leaves behind safety hazards.

Due to the wide range of use of intrusion alarm systems, different situations and environments may arise during installation. It is necessary to choose and install appropriate equipment according to the specific situation and environment, in order to form a safe and effective intrusion alarm system.
