15 Key Features to Look For in A Fall Alarm Radar Sensor
Fall Alarm Radar Sensor is a smart device that uses advanced technology to keep people safe. As the population ages, falls among the elderly are becoming an increasingly serious problem, and fall alarm radar sensors are becoming increasingly important.
Fall Alarm Radar Sensors are based on the 24GHz-60GHz radar frequency band, using the FMCW system, combined with MIMO and other technologies to achieve non-contact detection. Fall alarm radar sensors are an active radar sensing detection technology with the advantages of high accuracy, small size, and low cost. By transmitting and receiving electromagnetic waves, Millimeter wave radar can accurately measure the target object’s distance, speed, and direction. It is suitable for frequently visited places such as bathrooms, bedrooms, and living rooms to provide users with a full range of care services.
Since millimeter-wave radar is so important for families with elderly people, what should we pay attention to when choosing it?
1. Fall Alarm Radar Sensors Performance
(1) Detection accuracy
High-precision fall alarm radar sensors can accurately identify various falling postures and reduce false and missed alarm rates. For example, Homerda’s 60g millimeter wave radar fall sensor uses advanced technology to determine whether a person has fallen accurately.
(2) Detection distance and range
Choose fall alarm radar sensors with appropriate detection distance and range according to the size of the place of use. For example, some larger rooms or public places may require fall alarm radar sensors with longer detection distances and wider coverage; In contrast, for smaller places such as bathrooms, Millimeter wave radars with moderate detection distances can meet the needs.
(3) Response time
Fast response time is crucial. After detecting a fall event, the Millimeter wave radar should be able to issue an alarm in the shortest time possible to buy precious time for rescue. Generally, the shorter the response time, the better.
2. Functional Aspects
(4) Alarm methods
It is necessary to have multiple alarm methods, such as sound alarm, SMS notification, mobile phone APP push, etc., to ensure that relevant personnel can be notified in time under different circumstances. For example, when an elderly person falls alone at home, the sound alarm can attract the attention of the surrounding neighbors, and the SMS notification or APP push can let the family members know the situation the first time.
(5) Linkage function
Consider whether the fall alarm radar sensors can be linked with other smart home devices or systems, such as automatically turning on lights, unlocking doors, notifying medical staff, etc., to achieve more intelligent scene control and emergency response, and improve the convenience and safety of use.
(6) Anti-interference ability
In complex environments, such as the presence of multiple moving targets, electromagnetic interference, etc., the fall alarm radar sensors must be able to work stably, not be affected by interference factors, and accurately detect human falls. This is very important for practical applications in various places such as homes, hospitals, and nursing homes.
3. Installation and use
(7) Installation method
Choose a suitable installation method, such as wall-mounted or ceiling-mounted, according to the layout and size of the place of use. For example, if the bathroom is small, you can choose to install it on the wall near the toilet or shower area; if the living room is large, you can choose to install it on the ceiling to achieve a wider monitoring range.
(8) Installation height
Different installation heights may affect the monitoring effect of fall alarm radar sensors. They should be installed according to the requirements of the product manual. It is generally recommended to install them in a location that can fully cover the monitoring area and is not easily obstructed, such as Homerda’s FDVG3 60GHz Fall Alarm Radar Sensor. It is best to keep it 2 meters above the ground and install it vertically on the wall to reduce the false alarm rate.
(9) Power supply
Ensure that the power supply of the sensor is stable and reliable. You can choose battery power or AC power supply. At the same time, you should consider the battery life of the power supply or whether a power socket needs to be reserved.
4. Appearance and size
(10) Volume and weight
If the sensor is small and light, it will not only be easier to install, but also will not impose too many restrictions on the installation location, and it will be easier to integrate into the surrounding environment. For example, Homerda’s 24GHz Fall Alarm Radar Sensor FD60A1 weighs less than 120g, which is very light and easy to install.
(11) Appearance design
The appearance should be beautiful and match the decoration style of the place of use so that it can better integrate into the environment and avoid affecting the overall appearance.
5. Brand and after-sales service
(12) Brand Reputation
Choosing well-known brands and products with good reputations usually has better quality and more reliable technical support. You can refer to the evaluation of other users, the evaluation of professional organizations, and the market recognition to choose the brand.
(13) After-sales service
High-quality after-sales service can ensure that problems encountered during use are solved promptly, including product warranty period, maintenance service, technical consultation, and other aspects, which are very important in long-term use.
6. Price and cost
(14) Product price
The prices of Fall Alarm Radar Sensors of different brands, functions, and performances will vary. You should choose the right product according to your budget but do not just use price as the only selection criterion. You need to consider factors such as performance and function.
(15) Use cost
In addition to the purchase cost, you also need to consider the use cost of Fall Alarm Radar Sensors, such as battery replacement cost, energy consumption cost, etc. Choosing products with low energy consumption and low use cost can reduce the cost of long-term use.
In addition to the above points we should consider, the following points are also the reasons why our families should try to equip Fall Alarm Radar Sensors in daily life.
For example
Fall Alarm Radar Sensors can effectively cover the blind spots and restricted areas of the video surveillance system without the risk of privacy leakage;
Fall Alarm Radar Sensors are non-contact monitoring, and people do not need to wear any equipment, and are completely insensitive;
It can achieve accurate detection of subtle human activities, and can achieve more refined action recognition, such as gesture recognition, fall detection, etc.;
It can achieve accurate recognition of the number of people and movement trajectories indoors; it is not affected by ambient temperature, with a higher recognition rate and lower false alarm rate.
It can also monitor the activity status of people, and realize the alarm function when people fall or other dangerous actions occur;
Fall Alarm Radar Sensors can also monitor the movement trajectory of indoor people in real time, and realize the function of i
