Smart Home Security System – Key Sensors

Home automation is by no means just restricted to provide convenience to homeowners. One of the most compelling benefits of a smart home is that you can put together a reliable home security system.

A typical modern home security system consists of an automation hub (also known as the control panel), home surveillance cameras, motion sensor, magnetic sensors, smoke sensors and the Smartphone App (compatible with the automation hub). The hub connects to your home Wi-Fi and interacts with the different compatible automation devices, such as video cameras, sensors, remote light switches, weather devices and your heating/cooling control. By installing the Smartphone App, you can gain access to and control all the devices connected to your automation hub.

With reference to wireless home security, there seems to be a popular perception that it is just limited to installing IP cameras at crucial points in your home and having access to them real-time. Whilst this forms an integral part, there is more to a smart home monitoring system. Magnetic door sensors, smoke sensors and motion sensors make the wireless home security system complete. These sensors work with the hub and Smartphone App to give you a personalised ‘emergency’ alert system.

How wireless door sensors protect the key entry points in your home?

The magnetic door sensor comprises a switch which is activated every time a door/window is opened or closed. With the Smartphone App installed, you get a push notification when anyone tries to open the main door. If you have a security door camera installed, you can check out in real-time who is at your door while you are at office. As opposed to just relying on the video cameras, configuring these magnetic door sensors at key entry points gives you the peace of mind that your home is safe and secure.

How wireless smoke sensors notify you of fire outbreaks?

Your home security system is incomplete without wireless smoke detectors. Installing these sensors in all key areas of your home, including your kitchen, living room and bedroom, can help you take quick action during an emergency. Modern smoke sensors communicate with each other (in case there are multiple sensors installed in different areas) as well as the home automation control panel that plugs into your home Wi-Fi network. Using the Smartphone app, you can remotely know the status of all smoke detectors as well as receive push notifications whenever high carbon monoxide (CO) levels are detected. This helps you notify your neighbours and the fire authorities in case of an emergency when you are not at home.

How motion sensors warn you about potential intruders?

There are many types of motion sensors tailored for specific applications. For instance, an indoor motion sensor would typically be a passive infrared (PIR) sensor. PIR motion sensors are designed around a pyroelectric material which generates electricity when infrared waves are detected. This mean IR heat emitted by humans and animals trigger the sensor to transmit a signal to the receiver, which in turn, is connected to the main control panel. So, whenever a motion is detected, you get a push alert on your Smartphone through the app. So, whether you are at work or away from home, you remain aware of what is happening in your home so that you can take the appropriate action.
