The recent years we have seen the number of burglary and thefts escalate to unimaginable degrees. The skyrocketing terrors and smaller burglary situations give rise to better and carefully examined safety measure to be installed in homes both big and small. Security alarm system can provide you emergency service and you can connect the alarm with your CCTV’s. So if the CCTV’s capture any doubtful movements inside your premises then you will get the alarm directly. Apart from that, you must choose the security alarm system which has power backup because intruders always cut the main power source before attacking your property and it is important to install some wireless security alarms system with battery backup.
Different Types Components of Security Alarm Systems:
- A loud sounding alarm
- A sensor that should set off to sound the alarm
- A control that would be disturbed alerting or triggering the sensor.
These makeup fundamental components for security alarms. There are also other subcomponents that can go along with these like a remote, mechanism to set off phone alerts, cameras that can capture movements, or automated home or business sealing apparatus that could lock down the entire home and seal it up. Then there is equipment that are self-contained and those that have individual components, they have several uses and applications with these different types of security alarms too.
Types of Sensors used in the Security Alarm System:
Passive IR Sensors
These emit infra-red rays detecting the changes in the temperature of the surrounding, this triggers the alarm. When there is an intruder and the alarm is set off, it would detect any change in the room temperature, the temperature change that the intruders’ body temperature brings about in the room is detected and this quickly triggers the security alarms. This is the most commonly used and cheapest system that is employed by many.
The Infra-red detectors have components like microphones and digital converters to receive and record low frequency sounds, these are placed in areas where there is a higher chance of an intruder breaking in. Each time there is potential threat of an intruder making his way by checking if a door is closed or locked, and there is often creation of low frequency noise that is generated. This is captured by the is detector and alarm is set off.
Glass Break Detection
Often times, when glass breaks detecting an intruder or objects of destruction that has entered through the break needs to be detected precisely and the location accurately. This is achieved through capturing the specific shock frequencies that travel via glass and the ceilings surround the break. The frequency is generally around the 3 to 5 khz level, acoustic detectors are mounted and fixed close to glass panes and picks up the sound.
Smoke and Heat Detectors
There are smoke and heat detectors that can catch carbon monoxide and fire detection. Smoke detectors detect ionization, creating electric current that sets an alarm that triggers two alarm plates to create security alarms. It is suggested to check the frequency level and nigh-mode of the security system before install and they must have these features.
This is like a screen that runs around the fence area that could keep intruders at bay. Sometimes unwanted alarms from animals and birds can be triggered and these need to be adjusted to sense an amount of pressure. The downside is that it cannot be installed as a DIY and is expensive to install too.
Always choose an alarm system that matches your budget and is practical for all purposes. If you choose to use the help of a company to install the equipment, please ensure that prices are compared to other sellers too.
