Wireless alarms systems are one of the many types of home security systems available in the market. But did you know that there are also different types of alarms or sensors that can be used in a wireless alarm system? It is a good idea to get acquainted with some of the different sensors that are available, especially if you are thinking of investing in some type of wireless home security systems. You can then decide if you want to include these in your security setup. Here are four types of wireless sensors:
- Infrared sensors: These are one of the most common types of wireless sensors used in wireless home security systems and they are both affordable and reliable. They detect the infrared radiation emitted by a foreign object in a room. They are able to do so by keeping track of the ambient temperature in the room, and then detecting any change caused by a foreign object that emits infrared radiation, like human beings.
- Ultrasonic sensors: Unlike the above mentioned type of sensors, these sensors don’t detect intruders through measuring a parameter that is already present in a room or interior space. They emit their own form of energy, which here would be ultrasonic sound waves in the range of 15 kHz and 75 kHz. These sound waves are inaudible to humans, but the sensor can detect any change in frequencies caused by object movement. These are not used that frequently in wireless alarms systemsnowadays, or only in conjunction with other advanced sensors.
- Microwave sensors: In a wireless alarm system, you can also find microwave sensors. These too work on much the same principle as ultrasonic sensors. They emit microwave radiation and keep track of the energy reflected from solid bodies. These too detect motion by a sudden change in the frequency of the reflected energy. To eliminate any false alarms, they are often used with an infrared sensor in modern wireless alarms systems.
- Glass break sensors: These sensors are used to detect when someone is trying to break in through a glass window or door. They can work in two ways – they can either detect the sound caused by glass breaking, which surprisingly can sometimes be inaudible to the human ear, or the shock waves caused by a glass pane breaking. The first type needs to be positioned close to the windows or doors you want to monitor. The shock wave detectors have to be placed directly on the glass panes, in comparison, when used as part of a wireless alarm system.

2 Security Systems - Access Control Systems and Wireless Intruder Alarms ?
There are many types of security systems like access control systems and wireless alarmsystems available today. But are you that familiar with them? If no, then you should take a look at the brief descriptions of these two types of security systems given below. It could be useful if you ever need to get one of these systems in the future.Access Control Systems: These security setups are typically used to control access to a premise, whether it is residential or commercial. Though mostly used in offices, hotels and other big organizations, they can be found in use in a few posh condominiums and apartment buildings. Such systems are supposed to allow access to only authorized persons, who are supplied either special keys or cards, to let them get inside the premise. As they often record the time when such authorized persons go in or out, they also double up as time and attendance management systems in offices.Access control systems are typically equipped with a control pad which you swipe with a card, or insert a key into. The most advanced systems use biometric signatures of the authorized people, like their fingerprints, or iris patterns. They are often connected to electronic doors which open only when the system has verified the credentials of the person. In addition, there are often video and audio intercom systems for further security, in case someone misappropriates the key fobs or cards from authorized persons. You can fit access controls for a single door or hundreds, depending on your security needs.Wireless Intruder Alarms: Wireless intruder alarms are most often used in homes, especially in detached and stand alone properties, though they are not uncommon in big apartments and commercial premises as well. These intruder alarms do not actually stop intruders; they instead alert you to their presence, helping you and the police stop them before they commit any crime. Such wireless alarms are often monitored by a security agency, from an alarm receiving centre. They alert you and the police in case of any emergency. Some wireless systems also have the provision of informing the fire department, with smoke detectors being part of the setup.A wireless alarm system typically has motion sensors, which can detect motion by measuring the infra-red or ultrasonic radiation (or other variables) in a given space. It could also include glass break sensors, and smoke detectors, as mentioned. A wireless alarm system is not totally wire-less; the central control panel has to be connected through your telephone cable to the alarm monitoring centre. However, all the sensors are wireless and send their signals to the panel without any cables. This makes them hard to disable, especially if the main control is hidden in a safe place.Author:The author is an expert in writing articles about Access Control Systems and Intruder Alarms they are focus on doing things right.
