Sensors, Detectors, and Interior
DIY Home Security Alarms

Interior diy home security alarms help you establish the third layer of protection by using sensors and detectors purposely designed to identify forced entry attempts and environmental dangers.

Specifically things like the breaking of glass, the motion of a burglar, and the presence of gas, smoke, or heat in your home environment.

Home security alarms, sensors and detectors.

The sensors and detectors listed bellow are not standard features included in all DIY alarm systems. Depending on the DIY kit, you may need to purchase certain components separately.


Vibration sensor.

Glass Break Sensors – Glass break sensors protect your home against intruders who try to force their way in by breaking your windows.

These sensors are designed to detect the sound or the vibrations that are generated when glass breaks and shatters. If an intruder decides to break one of your windows to gain access into your home, the glass break sensor will differentiate that specific sound. It will then trigger the alarm’s siren.

Once fixed to the wall, a glass break sensor listens over an area of about 30 to 35 feet in all directions. They make an excellent addition to all home security alarms.


Motion sensor.
Motion Sensors - Motion sensors can detect the presence of a burglar in the event that he makes it past the first layer of protection and enters your home.

The moment the burglar attempt to cross the room, the motion sensor will detect his movement and sound the alarm. Today, all DIY alarm systems include a minimum of one motion sensor. When they are strategically placed in a room, they are an excellent security measure.

Detecting Environmental Changes

Home security alarms can detect and monitor sudden changes in a home’s environment through the use of different types of components such as specially designed detectors and sensors. In essence, these detectors and sensors keep your family safe from harm.

Environmental changes can include anything that is a threat or danger to the residents of the home.


CO detector.

Carbon Monoxide Detectors – You can’t smell carbon monoxide gas. You can’t see it. At high concentrations in a room, it can kill a person quickly and silently.

A carbon monoxide detector can save your life. It can detect the presence of this silent killer in your home and sound the alarm to get you out of the house.

These types of detectors are unfortunately not a standard feature in all DIY alarm systems, but they should be. Make sure your DIY home security alarm allows for the addition of a carbon monoxide detector before purchasing it.


Smoke alarm.

Smoke Alarms – If a fire breaks out in your home, a smoke alarm will detect the presence of the smoke and fire and sound the alarm.

More precisely, smoke alarms are designed to detect smoke particles in the air. Just like carbon monoxide detectors, they are early warning devices that save lives. They are a must for all DIY home alarms. In most communities, local by-laws make them obligatory for all residences.


Heat detector.

Heat Detectors – Heat detectors sense the rise of temperature in a room. When a room’s temperature rises above a certain level, the heat detector sounds the alarm’s siren.

Some heat detectors also monitor the rate of rise of the room’s temperature. If a room’s temperature rises too quickly, like in the case of a room on fire, the alarm’s siren is triggered.

Instead of purchasing two individual hardware components, heat detectors are also available with both heat detector capabilities and smoke alarms capabilities. Just like glass break sensors, heat detectors also make an excellent addition to all home security alarms.
