Security Detectors: What They Are, and How They Affect Home Safety

If you are looking around for a home security system or you want to upgrade your existing security system, you have probably heard about security detectors or sensors.  This is because they form a huge part of the technology found in modern security systems. Security detectors come in a variety, with each having a different function in the home security system. At the very least, you want a security system that caters to your security needs for that added peace of mind. For this reason, understanding different security detectors, and what they mean to your home security, can make it easier for you to make a decision. control systems to residential & business customers in Brisbane and the DSS Security Systems  Gold Coast.

So, what are these security detectors and how do they impact home safety?

What are security detectors?

Security detectors are security devices used to detect movements, activities, or changes in the environment where they are installed. They are designed to use different technologies to receive signals, analyze the signal and then respond to these signals by sending an alarm to the monitoring system when an anomalous signal is detected. A signal for detection could be in different forms such as reflected light, sound, movement, or body heat. Most home detectors have sensitivity and distance adjustments to ensure that they do not pick needless signals such as those from small pets, falling leaves, and the like. This way, they don’t send false alarms unnecessarily. offer a dynamic work environment that encourages growth, collaboration, and innovation.

Different types of security detectors

Deciding the types of detectors that are suitable for your home can be overwhelming and even confusing. Here are a few of them and how they are used in the home security system.

1. Motion detectors

Motion sensors detect movement around your home. If someone enters a room or is walking through your home when you are away, motion sensors detect that and send an alarm. Moreover, they are smart enough to distinguish between an intruder and your pet. You can use motion detectors in rooms that receive less activity or those with multiple doors. The common technology behind motion detectors is passive infrared (PIR) sensors, Wi-Fi sensing, tomographic sensors, and radar sensing. Mmwave radar sensing in particular has the ability to sense all types of movement in its radius while protecting the privacy of individuals. This kind of technology can also be installed in motion detectors that are already mounted in your home.

2. Environmental sensors

Floods, water leaks, and extreme heat conditions have destroyed many homes. Temperature detectors are usually attached to the HVAC system to sense when the temperature gets too high or too low. Too low a temperature can cause the pipes to freeze and burst, which increases the risk of flood. On the other hand, too high temperatures increase humidity, which promotes mildew growth. Flood sensors detect water leaks around the house to prevent flooding. Environment sensors installed in the kitchen, laundry room, basement, and bathrooms help keep your home safe from such threats.

3. Glass break sensors

These sensors are installed on windows and doors to detect when a glass shatters. Glass break detectors use built-in microphones technology to pick sound signals. These sensors can be able to differentiate between low pitches such as something hitting the glass and a high pitch of an intruder trying to get into your home by breaking the glass. The good thing is that you don’t have to install them on each window as a single one can detect breakage in about 25 feet distance.

4. Windows and door sensors

Windows and door sensors are installed on windows and doors, including cabinet doors. These detectors come with a magnet that is installed into the door or window, and a sensor attached to the frame. If the window or door is opened, the two separate, and an alarm is activated. This lets you see an unauthorized entry to your home or to your highly sensitive cabinets such as gun cabinets, medicine cabinets, and the like.

5. Smoke/fire detectors

Losing your property or life through the fire can be devastating. However, with smoke or fire detectors installed around the home, fire incidents can be detected early and necessary action taken before the worst happens. Smoke detectors are used to detect smoke in the air. Some smoke detectors work with photoelectric sensors while others use ionized sensors.

6. Carbon monoxide detectors

Just like smoke detectors, carbon monoxide sensors detect the presence of carbon monoxide in the air. They use technologies such as metal oxide, and electrochemical or biomimetic sensors. These detectors are highly advantageous in a home because carbon monoxide gas is odorless, colorless, and tasteless. These attributes make it undetectable by humans. Unfortunately, it can contaminate the air, causing headaches, dizziness, and unconsciousness. Additionally, carbon monoxide gas can cause a fire if it comes into contact with a flame.

How do these security detectors affect security at your home?

The impact of security detectors on your home security is positive. They enhance the security of your home in that nothing goes undetected. You can go about your day or get a good night’s sleep with peace of mind that your home and your loved ones are safe from intruders, fire, and environmental threats such as floods. In addition, they help you avoid intrusion to your gun cabinet, liquor and medicine cabinets especially if you have children or elderly relatives at home.


Home security systems are crucial for every home in protecting the home, valuables, and the people living there. Security detectors are a great part of the security system as they are the technology that allows different possibilities. This article has highlighted a few of these sensors. Hopefully, you are now equipped with the necessary insights to decide which ones suit your home.
