Why Home Security Matters

Before examining how wireless systems work, let’s look at some key statistics that highlight why home security is so important:

• The FBI reports a burglary occurs every 26 seconds on average.
• About 65% of break-ins target residential properties.
• Up to 60% of burglaries involve forcible entry through kicking in doors or breaking windows.
• Having a security system reduces your odds of being robbed by up to 300%.

These sobering stats make it clear why installing a comprehensive burglary protection system is a wise investment. Wireless systems provide that life safety layer for your home.

While nothing can guarantee you’ll never be victimized, having an alarm, cameras, and good home security practices can significantly reduce the odds. Let’s look at how modern wireless systems provide that protection.

Components of Wireless Burglar Alarms

A wireless security system consists of various sensors, detectors, and components that work together to detect intrusions and alerts residents and monitoring centers.

Here are the key elements:

The Control Panel

The control panel or alarm panel is the central brain of the system. It’s typically a small wall-mounted console that’s wired to a power source.

The panel has a numeric keypad for arming/disarming the system and display screens with status indicators for each sensor.

Sensors

Wireless sensors are positioned throughout the home and transmit signals to the control panel if disturbances are detected. Common sensor types include:

• Door/window sensors – Detect opening and closing and if a door or window is forced open.
• Motion sensors – Use microwave, infrared, or dual technology to detect movement and body heat.
• Smoke/CO detectors – Detect deadly smoke or carbon monoxide gas and alert occupants.
• Glass break sensors – Listen for certain noise frequencies that indicate glass being shattered.
• Flood/water sensors – Detect possible water leaks before major damage occurs.
• Temperature sensors – Monitor indoor and outdoor temperature extremes that could damage property.

Proper sensor placement is key to maximizing coverage and minimizing false alarms. Most sensors have adjustable sensitivity settings as well.

Alarm Sounders

When an intrusion is detected, the control panel triggers very loud audible alarm sounders to scare away burglars and alert people inside the home.

These usually mount on exterior walls or rooftops and emit a piercing 120+ decibel sound.

Some systems also have wireless strobe lights that flash rapidly to identify the home and attract attention.

Communication Modules

Wireless systems rely on communication modules to send alerts and alarm signals. There are several options:

• Cellular – Cell modules provide wireless connectivity through cellular networks without need for landlines or internet. This adds crucial redundancy if phone/internet service is disrupted.
• Internet – Many systems have internet modules that enable email, text, and push notification alerts when alarms are triggered. Video camera feeds can also be viewed remotely via apps.
• Landline – Landline modules connect to traditional telephone lines to call monitoring centers and deliver pre-recorded voice alerts when alarms are triggered.

Having dual or triple connectivity via cellular, internet, and landline modules ensures the highest reliability.

How Do Wireless Burglar Alarms Work

Now that we’ve covered the key components, let’s examine how they work together to detect intrusions and deliver alerts:

Step 1: Arming the System

Prior to leaving the home, the security system is armed using the numeric keypad on the control panel or wireless key fob.

This activates the sensors to detect disturbances while the home is vacant.

Entry delay times allow residents to enter and exit without setting off alarms. Exit delays provide time to leave before the system is fully armed.

Step 2: Sensor Activation

When a door/window or motion sensor detects movement or openings, a signal is wirelessly transmitted to the control panel. Signals have unique digital codes to identify which sensor was activated.

If the system is armed and the control panel receives an activation signal, it begins the alarm process.

Step 3: Sounding Alarms

First, the control panel triggers the onboard alarm sounders and any wireless sirens located around the home.

These create a cacophony to frighten intruders and alert residents and neighbors of the unauthorized entry.

Flashing strobe lights are also activated to visually identify the home. Lights, sirens, and other deterrents make it harder for thieves to continue the burglary attempt.

Step 4: Sending Alerts

Simultaneously, the communication modules swiftly transmit alarm notifications through the landline, cellular, and/or internet to monitoring centers and the homeowners themselves.

Alerts typically specify which sensor was activated so the threat can be evaluated accurately. Video camera feeds may also be accessed to visually verify the situation.

This rapid notification enables monitoring centers to dispatch first responders and allows homeowners to take action even if they’re away from the home when the alarm is triggered.

Step 5: Resetting the System

Once the threat is resolved, residents can enter a passcode on the control panel’s keypad to disable (disarm) the alarm.

Most systems require the code be entered within a short time limit or additional alerts will be sent.

Entering the code resets the various sensors so the system can be rearmed again once the home is vacated. This completes the alarm sequence.

Now that we’ve covered the basic alarm activation process, let’s look at the key advantages wireless systems offer compared to traditional wired ones.

Benefits of Wireless Burglar Alarm Systems

Wireless security systems provide several compelling benefits over hardwired alternatives:

Easier, Faster Installation

Wired systems require running conduit and cables through attics, walls, and ceilings – a tedious, messy process.

In contrast, wireless systems only require mounting the control panel and sensors, eliminating fish tapes and junction boxes.

This greatly reduces installation time and cost. Many wireless components use adhesive or screw mounts for quick attachment to surfaces. No wiring experience needed!

Flexibility & Portability
