Description of Application Scenarios

• This product is primarily designed for deployment in hospitals, nursing homes, and home healthcare settings. It can be installed not only in areas where traditional cameras are found but also in spaces where privacy is of greater concern, such as washrooms, bedrooms, and bathrooms.

• Capabilities of a Single HC2 Device Within a Maximum Detection Area of 24 ㎡
• The HC2 device can only activate its functions within the designated detection zone. These functions include:

Fall Detection
In the detection area, if a patient or elderly person falls and does not get up for more than 30 seconds (this duration can be set as needed), an alert will be sent to the management personnel through automatic phone calls and alarm voice messages via a web interface. This ensures timely discovery and handling of fall incidents, thereby reducing the liability and losses caused by falls.

Presence Detection
The system verifies whether a patient or older adult is in the room and pinpoints their exact location. Thisreduces the frequency of room checks by caregivers, particularly at night, thereby minimizing disturbances.

Respiration/Heart Rate Monitoring
Within the vicinity of a monitored bed, the device can remotely display the patient’s or elder’s respiration andheart rate (measured in beats/breaths per minute). In case of abnormal rates or pauses in breathing or heartbeats, caregivers are promptly alerted, avoiding the inconvenience and skin damage associated with long-term connected monitoring devices.

Bed Entry/Exit Detection
If a patient or elderly person leaves the bed area, the system can identify this within 1-3 seconds and providealerts via a web interface or phone calls (which require back-end setup). This reduces the risks associated with patients or elderly people leaving the bed without authorization and clearly delineates responsibilities.

Room Entry/Exit Detection
If a patient or senior exits the room, the system can recognize it within 5-120 seconds and provide promptson the web portal, minimizing risks related to unsupervised room departures.

Sleep Quality Monitoring
The device monitors the sleep patterns of patients or the elderly in the care bed area from 8:00 PM to 8:00 AM the following day. A sleep quality report for the individual is generated at 8:00 AM, summarizing the previous night’s data.

Voice intercom
In the event of a fall, abnormal breathing or heartbeat, or other situations where you need to contact the patient/elderly person, you can use the applet to call the designated device and initiate an intercom call.

Large Screen Display

• The large-screen dashboard provides a comprehensive display of data, including the number of devices, distribution of elder data, fall data distribution, chronic respiratory management distribution, number/frequency of apnoea episodes, sleep quality distribution, alarm occurrences, focal points for fall risk attention, and comprehensive risk concerns.
• The display on an individual device interface includes personal information, location, notes of caution, sleep details, respiratory status, heart rate, night-time bed exits, fall history, and health trend analysis.

Function Detailed Explanation

Position detection/alerts for entering and leaving beds and rooms
When installed correctly, it can be detected under a good network environment and within the detection range:

1. Accurately detect the presence of a human body and display it on the web page and the applet;
2. Identify the relative position of the person and display it on the web page and the applet;
3. After the bed area is defined, when the person enters/leaves the bed, the event of leaving/leaving the bed for too long can be recorded on the applet and web page, and through the background settings, the phone can be actively dialed to the mobile phone of the administrator as a reminder；

4. Once the door range is delineated, if a person enters/leaves the detection area, the departure event can be recorded on the applet and web side.

  *  **Attention!** When defining the area, it is essential to be as accurate as possible. If the demarcated area exceeds the actual room size, it may lead to the detection of false targets; if the defined area is smaller than the actual room size, detection will not be possible in the non-designated areas.
  *  **Attention!** This product supports the ceiling-mounted height of 2-3 meters. Installing it too high or too low will result in inaccurate person detection.
  *  **Attention!** This product supports the wall-mounted height of 1.5-1.6 meters. Installing it too high or too low will result in inaccurate respiration and heart rate detection.
  *  **Attention!** There may be a deviation of up to 50cm in a person’s relative position.
  *  **Attention!** When the radar’s line of sight is blocked by sofas, beds, cabinets, walls, thick glass, or thick wood panels, the obstructed area will not be able to detect human presence.
  *  **Attention!** When multiple people simultaneously enter or exit a door or bed, event reporting may be inaccurate.”

Fall detection
When installed correctly, it can be detected under a good network environment and within the detection range:

1. When 1-3 people are present simultaneously, someone falls.
2. When someone falls, it will be recognized as a “suspected fall” within 1-5 seconds and “fall” after 30 seconds (a longer time can be set according to the need) after “suspected fall.”

3. After being recognized as a fall, it will continue to announce “device name + someone has fallen, please deal with it quickly” on the web side and record it in the alarm center. The alarm will continue until the administrator finishes handling the alarm on the website/applet.

4. Identified as a fall, it will continue to issue a “beep-beep-beep” sound for 5-15 seconds in the applet. If you set up a telephone alarm, it will automatically dial the bound person’s phone. It will prompt: “Alarm notification, your device + device name + monitoring anomalies after connecting, please deal with it as quickly as possible！”

   • Attention! When setting the radar detection area, if the demarcated area extends beyond the wall by more than 50cm, false alarms may occur; if the demarcated area is smaller than the actual room size, falls cannot be detected in the non-designated areas.
   • Attention! This product supports the ceiling-mounted height of 2-3 meters. Installing it too high or too low will result in inaccurate fall measurements.
   • Attention! This product supports the wall-mounted height of 1.5-1.6 meters. Installing it too high or too low will result in inaccurate respiration and heart rate detection.
   • Attention! If the set height of the radar in the back-end differs by 5cm or more from the actual installation height, it will lead to serious false alarms or missed detection! Precise measurement with a distance or tape measure is required when setting the height.
   • Attention! Fall events cannot be triggered if an area is defined as a bed (Whether it’s a regular bed or a care bed).
   • Attention! Fall events cannot be triggered if an area is defined as a door.
   • Attention! If a person sits or lies half-down on the ground after falling, it may not be judged as a fall.
   • Attention! Bunk beds may cause limitations in radar detection near the bed, leading to false triggering of fall events.
   • Attention! When the radar is installed on the ceiling, if the installation location is ≤50cm away from the wall, or if the tilt angle is greater than 3° (shown at the bottom of the ‘Device Monitoring’ page on the web interface and the ‘Function Properties’ page on the mini-program), it may produce more false alarms or missed detection! The radar installation location should be by the recommended positions in the ‘Installation Manual.’
   • Attention! In the detection area, behaviors such as doing push-ups or yoga on the floor, children playing on the ground, or someone squatting and moving water in a basin may be considered falls.
   • Attention! When the radar’s line of sight is blocked by sofas, beds, cabinets, walls, thick glass, or wooden boards, the obstructed area may not be considered a fall.
   • Attention! The movement of curtains in the wind has a small probability of being judged as a fall.
   • Attention! Pets jumping from high places or walking past people have a small probability of being judged as a fall.
   • Attention! Flowing or moving water on the ground has a small probability of being judged as a fall.
   • Attention! When other people or sources of interference (such as oscillating fans, swinging plants, other people, large pets) are within 1.5 meters of a fall, it may not be judged as a fall.”

Respiration/heart-rate/sleep quality detection
When correctly installed, it can be detected within the range of the monitoring bed:

1. real-time values of respiration and heart rate (beats/minute) and display them on the web terminal and applet.

2. Whether it exceeds or falls below the threshold (respiratory threshold is eight beats/24 beats, heartbeat threshold is 50 beats/90 beats). If the test data exceeds the threshold, it will be recorded on the website and the applet.

3. Sleep Quality: By collecting information on breathing, heartbeat, and being out of bed from 8 pm to 8 am, a sleep quality report is generated at 8 am the next day. The report includes sleep score, sleep efficiency, duration of sleep, time and proportion of deep sleep, time and proportion of light sleep, number of times out of bed, number of apnoea, number and time of over/under respiration, number and time of over/under heartbeat.

4. Digital Portrait: Horizontally compares the trends of various body metrics within a month and provides a simple assessment. The more data available, the more accurate the digital portrait becomes.

5. Apnoea: If breathing stops for more than 20 seconds, it will be detected as “apnoea,” the related events will be recorded on the websites and applet.
6. Leaving the bed: within the range of 8 pm to 8 am, if the person has left the bed, the number and time of leaving the bed will be recorded.

  *  **Attention!** When more than one person is in the detection range, or if there are other sources of interference (such as large pets, running fans, flowing water), the accuracy of breathing and heart rate detection may be compromised. The sleep report may show issues such as abnormally high or low breathing, heart rates, or inaccurate apnoea detection.
  *  **Attention!** Suppose a continuously running fan is present within the care bed area. In that case, it may lead to the failure of sleep detection, and the sleep report may show issues such as abnormally high or low breathing and heart rates or inaccurate detection of apnoea.
  *  **Attention!** Changes such as a fan stopping or curtains ceasing to sway may trigger false ‘weak vital signs’ alarms.
  *  **Attention!** The assessment results from the digital portrait should not be taken as medical conclusions.
  *  **Attention!** Individuals must sleep on the care bed, and the duration should be between 8 pm and 8 am, with over 3 hours spent on the bed, to generate a sleep report; sleeping on a regular bed will not produce a sleep report.
  *  **Attention!** This product supports the ceiling-mounted height of 2-3 meters. Installing it too high or too low will result in inaccurate breathing and heart rate detection.
  *  **Attention!** This product supports the wall-mounted height of 1.5-1.6 meters. Installing it too high or too low will result in inaccurate respiration and heart rate detection.
  *  **Attention!** The accuracy of breathing and heart rate detection varies from person to person.
  *  **Attention!** It is normal for a person to experience a small amount of apnoea or have high/low breathing rates during sleep.
  *  **Attention!** Failure to install the product according to the ‘Installation and Usage Instructions’ may lead to inaccurate measurements.
  *  **Attention!** Accurate measurements can only be taken when a person is lying on the bed. Sitting or standing positions will result in inaccurate measurements.
