  • 1- What are the benefits of installing home security alarm systems?

It’s always beneficial to improve your quality of life, and even more advantageous if it’s about your personal security and safety. Our life, especially that of those we love, are the dearest to our hearts. Moreover, we worked hard to have our property and belongings. So, why not invest in such an important field right away? Below are the key benefits of installing security systems:


First of all, home security systems’ crucial role is to protect your premises and your family from any intrusion, hazardous disaster, or even prevent any potential fire. These systems are also able to protect you from dangers that are not aware of. While installing security systems might be expensive, but burglaries and thefts cause huge losses that cost more! According to a 2019 survey led by the FBI, victims of such intrusions suffered around 3 billion dollars in property losses. Besides physical losses, burglaries and other accidents also have psychological impacts on people, who sometimes can never compensate for the loss.

Hinder Burglars

By installing security alarm systems, you will deter intruders and burglars, as the alarm sign will decrease the probability of any robbery. In a 2021 survey, experts asked accused burglars what deterred them the most when considering entering a property. Around 50 percent confessed that they wouldn’t enter a home or building with working home security alarm systems. An additional 23 percent claimed that even seeing sensors or any evidence of an alarm system was enough to deter them.


Whether you are sleeping safely and soundly at home or away on some vacation, you will be at peace knowing that your property and family are safe. You will also be sure that it is protecting them from intruders and potential environmental disasters. You will be able as well to check in on your security alarm system from anywhere, thanks to its connection to the internet.

Energy Saving

All modern surveillance systems comprise home mechanization. This option offers comfort and saves energy, which explains the additional price you pay for them. Internet lights, detectors, and thermostats connected to your surveillance system will adapt themselves to save energy when the system is on. Furthermore, you can alter the temperature and turn devices on and off whenever needed. That way, you will secure your home and save on energy bills.

Remote Access

Nowadays, amidst the era of mobile phones, we tend to control our lives through this pocket device. You can integrate home alarm systems into your smart home technology, or into other security systems like CCTV cameras, home access control, and video intercom. You can control all these systems including alarm systems on your mobile. Arm or disarm once you want to give access to someone to enter from your convenient location. Manage your system schedule based on your convenient time and quickly edit this from your comfort.

Once an alarm is armed, you can check your cameras on your mobile, and detect whether a pet crossed your fence or a thief. Our home security alarm systems offer independence, flexibility, and capability to control.

2- How do home security systems work?

Home security alarm systems operate by transmitting alerts to the brain of the system, which is the main monitoring part when detectors are faulted. This main epicenter is the control panel. All the sensors and the whole tools of the system intercommunicate with the control panel. The brain needs as well a communicator to send outbound transmissions.

The objective of a home security system is to allow the user and the police or the monitoring center to be informed of any crisis that may happen. Crises might include intrusions, fire, environmental problems, or health crises. The alarm system recognizes these crises by employing varied sensors. The most used sensors for these emergencies comprise door and window contacts, motion-detecting sensors, glass-break sensors, smoke detectors, heat sensors, flood detectors, and temperature detectors. Sensors can be connected to an alarm system wirelessly through a wireless receiver or by being hardwired.

Sensors operation

When a detector or sensor is armed or disarmed, it transmits a signal to the brain of the system. The alarm system then reacts based on the already set settings for the zone in question. For instance, if a sensor is activated, it might send alarms when the system is on, while other sensors may send alarms at any moment, no matter what is the existing status of the alarm system. Make sure that the settings of the sensors of the alarm system are well programmed. You can also program zones in a way to have a delay period, which allows the user to have enough time to disarm the alarm system before any signal is transmitted.

When an alarm signal is sent out, the system transmits an alert to a central surveillance station. Nowadays, most surveillance systems communicate through the internet or a cellular to transmit signals. The central station operates 24 hours, 7 days a week. A qualified dispatcher will instantly detect the signal and contacts right away the user and/or the concerned authorities. If the dispatcher does not obtain confirmation of the faultiness of the alarm, then the local authorities will visit the premises as quickly as possible.


There is also self-monitoring, in which case the security system does not communicate with a monitoring station. Rather, the system directly warns the end-user by sending a text message or an email. An interactive assistance platform allows this communication, such as Total Connect 2.0 or Alarm.com. Then, the end-user will have to decide whether he or she wants to contact the local authorities. This option is considered to be great if the end-user is convinced that the authorities respond to text messages and/or emails quickly and consistently, once he or she informs them of any incident.

3- Home alarm systems installation directions

Do It Yourself (DIY) vs. professionally-installed

You could DIY-install your alarm system, all by yourself, or you could use the help of a professional for the system setup. It all depends on the size of the system and its purpose.

You could opt for the DIY option if you just wish to monitor what’s happening outside your house and if you are on a stretched budget.

However, if high-tech and all-inclusive security standards are what you are looking for, then, you do need the help of an alarm company and professional installers of alarm systems.

If you want some reasons to convince you why you, especially businesses, have to consider hiring a security alarm company to install alarm systems, here are some. It’s easier, the installer takes care of the maintenance and updates of the system, when anything in the system goes wrong you will get assistance right away, you will be installing the latest surveillance technology, you will pay the most reasonable prices for the parts of the system, the installation process may even include monitoring services.

Monitored vs. Unmonitored

Alarm installation experts do not always offer the monitoring option, and not always, the alarm systems do have this option either. However, it is very important and many alarm system companies who install your alarm systems will suggest as well to monitor your system and maintain it. Opting for this option will allow you to have an anxiety-free security experience. If the alarm company that installed your system does not offer this option, it will certainly be partnered with one that offers monitoring services, and thus, can get you in contact with it.

Hardwired vs. Wireless

If you install a hardwired security alarm system, you will have a personalized series of already-installed monitors and sensors. Contrary to what most people think, just cutting any old cable or wire won’t disable the alarm system. Moreover, hardwired systems do not rely on batteries for power, so you won’t have to regularly buy new ones. Besides, this system is usually a low-cost one.

As for the wireless option, you can add wireless sensors or wireless keypads to your current alarm system. That way, the sensors of your door and windows are connected to a wireless central that transmits the signals to a keypad that is also wireless. So, if it’s just your doors and windows you want to monitor, then hardwired systems are the best for you. If you want more than that, go wireless.
