Choosing the alarm system for your house

Home security systems consist of several different devices working together which ensures protection for the entire house and your private territory.

Door and window sensors are the basis of any security system since they let the homeowner monitor which windows and doors open or close.

Security systems for doors and windows are often identical.

Most of the alarm systems use a whole range of sensors. Additional sensors might be added and installed depending on the needs and preferences of a customer. Ideally, sensors should be placed on all doors and windows of the house. If a window or a door is opened or broken when the alarm is on, the sensor sends a signal to the main control panel which immediately activates the alarm.

How do door and window alarm sensor work?

Door and window sensors usually consist of two pieces. One of them is placed directly on the door or window, and the second one is fitted on a movable frame or glass. The sensors might be glued or screwed.

Two pieces of the sensor are fitted at a very close distance from each other which creates a current in a closed electrical circuit. When the door or window is opened, this circuit breaks and it sends an alarm signal to the control panel, which, depending on the model, either turns on the siren or notifies the owner via the mobile app, or even sends a signal directly to the police.

In this review, we will take a look at security systems for self-installation which do not require the connection to the Central Monitoring Stations and additional payments for their maintenance.

These alarms might be installed without professional help, and in case of an emergency they will alert the owner with a loud signal and send a message to the phone.

What types of alarms are used to protect the house against unauthorized intrusion?

The following types of sensors in house security system are the most common ones:

1. Passive Infrared Motion Detectors

This is one of the most common types of sensors since these devices are very practical and quite affordable. These sensors monitor the temperature mode in front of them using infrared radiation. If the device detects the temperature change associated with the appearance of a person or an animal, it automatically triggers the alarm.

It is important to note that infrared radiation does not go through the walls, windows and doors and can be detected only in an open space, so these sensors need no be installed in each room separately.

2. Ultrasonic Detectors

Ultrasonic sensors use high-frequency sound waves that track any kind of movement within a certain room.

Sensors transmit 25 to 75 kHz signal which is inaudible to the human ear. Once the alarm is activated, the sound waves are being emitted and reflected from the walls, furniture and other objects which creates some kind of volumetric sound picture of the room. In a person comes into the room, the sound reflection changes and it disturbs the whole sound picture, which means someone has intruded the house.

3. Microwave Detectors

Microwave detectors works on the same principle as ultrasound sensors. The only difference is that such sensors use high-frequency radio waves instead of sound waves. The advantage the detectors of this type is that radio waves can pass through the walls, so that they provide relatively greater coverage compared to their ultrasonic rivals.

4. Photoelectric Beams

Two photoelectric sensors are installed within the line of sight and their photocells are connected to each other by a stream of infrared radiation. If some obstacle appears between the sensors, the connection between them fails, and it indicates that there are strangers in the room.

5. Glass Break Detectors

This type of sensors reacts to changes in the background sound inside the room. Breaking the glass or breaking the door is accompanied by an increase in the background sound which the sensors detect. The alarm is activated immediately after the sound mode is disturbed.
