What Is A Home Security System?

A home security system is a collection of physical and electrical components that work together to keep a house safe.

Read our SimpliSafe, ADT, or Vivint reviews if you want to see actual systems. A home security system has many different objects.

Security Camera

Security Camera

Smart security cameras connect to Wi-Fi, allowing us to remotely livestream images of our system and receive alerts when our cameras detect movement, persons, or parcels.

Motion Sensor

Motion Sensor

Motion sensors should install in a major doorway or hallway on the ground level of a property to detect motion and notify us when our security system is activated.

Because certain motion sensors are pet-sensitive, they do not go off every time our dog goes by.

Entry Sensor

Entry Sensor

Entry sensors, also known as contact sensors, have two parts: one for the window or door and one for the frame.

When one of these openings is open or closed, these sensors employ magnets to detect it. The sensor will notify us if it believes an entrance point is open.

On the other hand, we recommend installing entry sensors on windows or doors.

The majority of them are battery-operated, and many of them come with adhesive backings for simple installation.

Glass Break Sensor

Glass Break Sensor

Intruders will sometimes smash windows open instead of opening them the traditional method to avoid setting off the entry sensors.

On the other hand, a glass break sensor detects the sound of glass breaking and sends us a text message.

Control Hub or Panel

Control Hub or Panel

A control panel is the heart or the main part of the security system, which uses radio signals to communicate with other security devices along with the monitoring system and helps in arming & disarming the security system.

You can control it using a built-in keypad or using your phone or even voice command, given that your control panel supports it.

High-decibel sirens

High-decibel sirens

There is nothing better than old-fashioned sirens, and even the most advanced home security companies offer them.

A high-decibel siren comes built-in into the hub and can be added even externally. These sirens make noise of 80-115 decibels which is great for scaring away burglars.

Key Pad or Key Fob

Key Pad or Key Fob

A keypad or key fob comes in handy for controlling the security system. You can often find this built-in into your security system, and if not, then you can get it added externally.

Some home security system also allows wireless control from a dedicated app to manage the alarm.

Yard Signs & Stickers

Bold & flashy yard signs & stickers can be used as the first line of defense to scare away burglars.

In fact, according to a study by the Department of Criminal Justice and Criminology, burglars have agreed not to break into a house that has yard stickers or signs on them.

How Does It Work?

Home security systems have the basic notion of safeguarding access points in a home using sensors that communicate with the command center in a convenient place within the home.

The sensors are often in front and back doors and easily accessible windows, especially those that open, especially those at ground level.

You can use motion sensors to safeguard open spaces within homes. Depending on what kind of sensor or security system you have in place, the way of work could significantly change.

For example, the most common way is the control panel. The control panel is a computer that arms and disarms security systems, connect with all installed components, sounds an alert when a security zone is broken and communicates with an alarm monitoring provider.

They usually have a touchpad for interaction and simple programming, a passcode entry area for arming and disarming the system, the ability to function with voice commands, and the ability to work with wireless remote devices called key fobs.

What Happens During An Intrusion?

What Happens During An Intrusion

When there is a breach in the secure zone of the security system, the system undertakes specific duties.

The kind of security system you have determines what happens in the case of an incursion.

If an alarm provider professionally monitors your security system, the monitoring firm gets notified in addition to the high-decibel alarm.

If the control panel has 2-Way Voice communication, a certified security professional may attempt to connect with the homeowner via the control panel or phone the emergency contact number given on the account.

The monitoring firm will alert the proper emergency response people in your region in the case of a real emergency.

Police, firefighters, and paramedics are all on this alert. Until emergency response personnel arrive at your house, the monitoring firm will endeavor to keep in touch with you.

If you have a DIY security system, things are a bit different. Today, there are several DIY security systems available that do not require expert monitoring.

When you have this sort of security system, a high-decibel alert rings in the case of a house invasion (if you already have one).

The homeowner must start contact with police, fire, or other emergency response professionals by dialing the correct number, often 911.
