Wave Wave Wave

100% Non-Contact
Fall Detection System with IR-UWB Radar

No wearables. No pressure pads. No cameras. The only fall detection and alert system that provides 99% miss detection free and 96% false alarm free performance without the headaches of privacy issues.

Easy to Install

KARDIAN can be used on a nightstand with Wi-Fi connection for homes and it can also be installed on the walls or ceiling of hospitals and nursing homes with simple wiring.


Unlike wearable based fall detection systems, KARDIAN can even detect slow "sliding falls".


Kardian devices are not affetected by dirt, dust, light or temperature. There is no physical maintenance to worry about. There is also no need to replace any parts unlike pressure pad based systems.

How Does It Work?

The core hardware technology powering KARDIAN is IR-UWB RADAR which stands for impulse radio ultra wide band radar. It sends out 20,000 nano-pulses per second and gather valueable data to its surrounding. Micro movements and vibrations such as chest movement from breathing and heart beats are detected and monitored. Fall detection looks at distance, movement and speed (time of flight) to determine falls.

How Does It Work?
What Is It

IR-UWB stands for Impulse Radio Ultra Wide Band radar. It is essentially a very wide bandwidth (low emitted power) with lots of multipath at 500MhZ frequency.

Key Functions

Kardians patented technology can detect and monitor health vitals such as heart rate, breathing rate, sleep apnea, fall detection and can also be used as a PERS (personal emergency response system) device.

How does it work

IR-UWB emits very short energy pulses, typically on the order of hundreds of picoseconds, that are transmitted with the use of a specially designed wideband antenna. KARDIAN has developed unique algorithm that can use IR-UWB to create adjacent thin layers vertically creating a “field” that can detect health vitals.

Health risk-free

IR-UWB operates at a wide, but low bandwidth – 500Mhz. In other words, it emits less than 10,000th to 100,000th less signals than a standard wireless Wi-Fi router. It is completely health-risk free to use on a daily basis.


Fall Detection features by Kardian

World's first and only commercial and medical grade level fall detection system that is 100% contactless

Sit Up Detection

Sit Up Detection

For hospitals and senior care facilities, caretakers must be made aware of "sit-ups" as well in order to act quickly and prevent the patient from attempting to get off the bed on their own. KARDIAN can accurately and rapidly detect sit-ups from a bed or chair - including toilet seat and send alerts accordingly.

Slip & Fall Detection

Slip & Fall Detection

In certain situations - such as a bathroom, slip & falls can occur that can cause severe injuries. Kardian detects these types of falls with impeccable accuracy.

Sliding Fall Detection

Sliding Fall Detection

Fall detection at home is largely monitored via a wearable – most often used as a pendant. It has several sensors including accelerometer, gyroscope and sometimes barometer all designed to detect “sudden falls”. However, not all falls are drastic, severe, sudden falls. Some falls, such as from fainting or slow motion falls (sliding falls) are virtually impossible for wearables to detect. Hence, when they claim “95% accuracy”, the 5% is most likely referring to not detecting sliding falls. Kardian on the other hand accurately detects and monitors for sliding falls. This is why it can also see falls from chairs as well.

Privacy Protected

Privacy Protected

The only other known contactless fall detection system is a system that uses 3D stereo vision cameras or kinect depth based infrared cameras. Both of these technologies still use a form of a camera lens, which can cause discomfort among users concerned for their privacy – especially when used in a bedroom or bathroom. Furthermore, it requires physical maintenance (lens must be kept clean) and is sensitive to light and temperature. Kardian on the other hand only sees data. There is no camera at all. It is also unaffected by light or temperature.

Post-Fall Monitoring

Post-Fall Monitoring

While most competitors finish at alerting a fall, Kardian keeps going. It continues to monitor to see if the person gets back up – reducing false alarms even further. If the person does not get up or move, it will start reading their respiration rate and movement index pattern. All of this data will be sent in real-time to the designated caretaker via a mobile app. There is also an optional “call patient” feature where the caretaker can also make a direct call via VOIP and speak to them through the embedded speaker/mic.

Notification via Designated App

Notification via Designated App

For professional medical or senior care facilities, a designated app can be installed on a smartphone with option to select rooms or zones. If a fall is detected in these zones, it will send the alert to the designated app of the designated smartphone. For homes, the customer can designate a caretaker of up to 5 people. The customer also has the option of signing up with KARDIAN’s partner company – RAPIDSOS in order to be able to connect directly to 911 / first responders.

Bathroom Fall Detection Demo

4 out of 5 injuries that occur in bathrooms are caused by falls. 33% of seniors required hospital admission following a bathroom fall. In some instances, hospitals and nursing care facilities have been sued for negligence due to a bathroom fall while the patient was in their car. One of the biggest challenge has been privacy. Wearables are not waterproof and even if they were, customers wouldn’t want to wear them to the bathroom. Pressure pads on the toilet seat only tells the caretakers that the patient has come off the seat but not necessarily tell them if he/she has fallen or not. Cameras poses extreme privacy concerns, especially in a bathroom scenario. KARDIAN is truly the one and only solution available when it comes to providing accurate and reliable fall detection without any privacy concerns whatsoever.

Fall Detection From A Bed Demo

Kardian has the unique ability to detect objects and people separately. With its radar technology, it can also auto-detect and calculate the distance of the floor. This is important as it can also determine if someone “fell” on a sofa or bed which could be intentional. Video below demonstrates various types of falls that can occur from a bed.

Competition Comparison

KARDIAN has a clear advantage over its competitors due to the fact that it uses a completely different technology that has never been available in the past. It has the highest accuracy rate, lowest false alarm alarm rate, is 100% contact free (wireless) and is most reliable to use over time since it is not affected by environmental contamination such as dust/grime build up, lighting and physical abuse (pressure pads).


Wearable Fall Detection

All wearable based fall detection systems rely on accelerometer, gyroscope and sometimes barometer sensors to look for sudden falls. The key word here however is “sudden” as wearable devices are not able to look for slow, sliding falls or differentiate between intentional falls (to a sofa or bed) and accidental falls. Another major hurdle for wearable based fall detection systems is that it must be physically worn at all times. Many users prefer not to wear one while they are sleeping (accidental presses causes false alarms) or while they are in the bathroom.


Camera / Kinect Detection

3D Stereovision cameras or Kinect which uses infrared laser and monochrome CMOS sensors which captures video data in 3D under ambient light conditions relies on the principle of looking for “patterns” that correlates to a fall. Unfortunately, it must have enough lighting to work and the lens must be maintained properly (it must not be blocked, dust/grime from cooking can interfere). For instance, if you fall from the bed when the lights are all out, the system may not detect the fall completely. 3D based cameras require time-consuming calibration process in order for it to work properly. Privacy is also a big concern. Although it is technically privacy protected in the sense that facial recognition is inhibited, it still is a camera looking down on people while they are in the bedroom or bathroom which can cause discomfort.


Pressure Pad Detection

Since hospitals and senior care facilities cannot tolerate even a 1% chance of miss detection, pressure pad based systems are commonly used for fall detection. The system is carefully calibrated to detect for actual falls rather than when the patient is tossing and turning on the bed. This is also the reason why these pads comes with a limited 6 months or 12 months warranty period and has to be replaced. The entire setup is very costly and running expenses are usually in the hundreds of dollars per year.

What Else Can KARDIAN Do?

Kardian’s technology provides complete remote health monitoring including fall detection, breathing rate / resting heart rate detection, sleep apnea (OSA) as well as provide urgent action upon a possible medical emergency (PERS).

Resting Heart Rate

New studies have discovered that monitoring for resting heart rate and looking for sudden increases over a period of time can provide foresight to severe cardiac problems in the near future.

Sleep Apnea Monitoring

More than 18 million Americans suffer from OSA (Obstructive Sleep Apnea) which can cause lack of concentration, memory loss, depression or if left untreated can cause high blood pressure, stroke (2X risk), heart disease, dementia and even diabetes.

Personal Emergency Response System (Pers)

1 in 6 people in the world is 65 years old or older. As people age, they may need immediate medical assistance. Kardian is able to provide health monitoring and alert 911 directly faster than any other PERS monitoring service provider.
