The following is a quickstart guide of the Sentinare sensor and the App, including some video demos. More videos are available at our YouTube channel.

1: Download the Sentinare App

To use the Sentinare sensor, you need to install the free Sentinare Activity Sensor (formely known as the Cypress visual sensor) App on your mobile device. The sensor also needs to connect to the Internet via a WiFi network with WPA2-PSK (aka WPS2-Personal) security protocol. Sentinare 2 supports both 2.4GHz and 5GHz WiFi, whereas Sentinare 3 only supports 2.4GHz WiFi. However, it can still work with 5GHz-only WiFi with the help of a dual-band WiFi extender. Refer to Sec. 4.1.2 Set Up WiFi of the User Manual or Sec. 3 below for details.

Please choose the following download method depending on your mobile device’s platform:

2: Create a Sentinare Account

• Open the Sentinare App on your mobile device, tap the “Create an Account” on the front page.
  • Note: The Sentinare App account is different from your Shopping account at the AltumView website!
• In the “Sign Up” page, fill in your name, email, and password. The email and password are used for login. Please follow the displayed requirements for password format.
• Choose your Server: Tap the pencil icon to choose a server location.
  • Currently, there are three servers in United States, Canada, and China.
  • When a sensor is sold, its serial number is added to the white list of only one server, based on the country where the device is sold. If you are not in these three countries, please choose the US server.
• Read and accept the Terms of Services, then select “I agree to Terms of Service”.
• Tap the “Sign Up” button. After that, you will receive a verification code in your email account. If you could not get it after a few minutes, please make sure your email address is spelled correctly, and check your junk mail folder.
• Enter the verification code to the next “Confirm Email” page, then tap “Continue” to enter your account.

App Permissions: When you first use the Sentinare app, it will ask for your permissions to use certain features, such as push notification, Bluetooth, and location. Note that you may need to disable some power/battery saving settings of your phone in order to receive alert notifications when the Sentinare app is running in the background. See Sec. 1.4.1 of the User Manual for details.

The following is a video demo of creating a Sentinare account.

3: Add the Sensor to Your Account and Setup WiFi

Since you may need to try several installation positions before finding the best spot, it is recommended to add the sensor to your account and set up WiFi first, before installing the sensor.

• Connect the power and wait until the LED of the sensor flashes white for about 20 seconds. The button on the top is for factory reset, and is NOT needed to turn on the sensor.
• Open the Sentinare App. Tap the Rooms icon in the menu bar at the bottom of the screen. When a new account is created, a default room “1st Floor- Room 1” is created (you can rename it). To add your new sensor, click on the room name “1st Floor- Room 1” to expand it.
• In the next room page, click the “+Add Device” command. The App will search and list all nearby sensors.
• Note: A sensor can only be added to one account at any time. Each room can have up to 10 sensors. If a sensor has been added into another account, its status will be displayed as “Added”, and it cannot be added to a new account unless it is removed from the original account. See the User Manual for details.
• Select the sensor to be added according to its serial number. The LED of the selected sensor will flash green for 20 seconds. In the next page, create a name for the sensor.
• Setting up WiFi: Next the App will set up the WiFi for the sensor. The App will first scan available WIFI networks with WPA2-PSK (aka WPS2-Personal) security protocol. Selecting your WiFi network and entering its password, the LED on the sensor will first turn to red, then yellow and blue, and eventually become steady green. After that, this sensor will connect to WiFi and the server, and appear in the list of sensors in the room.
• Firmware Upgrade: After adding a sensor to the account, if its firmware is not the latest, please upgrade the sensor’s firmware. Please always use the latest firmware as we are constantly improving the firmware. The upgrade might take a few minutes, and the sensor might reboot multiple times. After the upgrade is finished, the sensor will show a steady green light. Please refer to the Upgrade Firmware section in the User Manual for details.

WiFi Extender for Weak WiFi and 5GHz-only WiFi

If the WiFi signal at the Sentinare sensor’s location is too weak, or if you have a 5GHz-only WiFi (Sentinare 3 only supports 2.4GHz WiFi), you can purchase a dual-band WiFi extender, such as the following:

https://www.amazon.com/dp/B07N1WW638

https://www.amazon.ca/dp/B0D41G5N95

During the setup of the WiFi extender, ensure to activate the 2.4 GHz or dual-band WiFi option to enable the extender to transmit the 2.4 GHz WiFi signal required by Sentinare 3.

After setting up WiFi, the App will ask you to do calibration, which is required for fall detection. Since the sensor has not been installed properly yet, you can select Later in the “Calibration Required” page, and do the calibration after the installation of the sensor in the next step.

The following is a video demo of adding a sensor to an account, setting up WiFi, and performing floor calibration.

4: Install the Sensor

Unplug the power of the sensor. Find an installation position that is about 1.5-2.5m (5-8 ft) above the floor. Install the sensor temporarily such as using packing tape, as you may need to adjust it during the subsequent calibration step.

Tilt it down slightly so that it can monitor most of the room and the floor for fall detection without occlusion. The sensor should not rotate to the left or right, i.e., the line between the lens and the LED light should be vertical. Otherwise, the fall detection algorithm could be confused and generate false alarms.

• The stand/bracket can be mounted on a horizontal surface, on the wall, or on the ceiling.
• The sensor can be installed Upside-Down. In this case, you need to turn on the Upside-Down Installation flag in the app.
• If you want to use face recognition (optional), including the Region of Interest feature, the ideal installation height is no more than 2m, so that it can capture and recognize people’s front faces.

The following are different ways to install the Sentinare 3 sensor. Sentinare 3 comes with an 8ft Type C USB cable. You can use other Type C USB cables if you need, as all Type C USB cables can carry at least 3A current, and Sentinare 3 only needs 2A at the most.

The following are different ways to install the Sentinare 2 sensor, with the optional ball head. Sentinare 2 comes with a USB power adapter with 1.5-meter 20 AWG micro USB cable. Please do NOT use other adapter or USB cable, as they may not be able to power the sensor properly. Regular AC power extension cord is recommended to connect the USB power adapter to AC power outlet.

Other Mounting Options

The Sentinare sensor has standard mounting hole with 1/4″-20 tripod screw thread. Therefore it can be used with many other mounting stands. The following are some adhesive mounting stands with 360-degree ball head that can be used with our sensor. Hook & loop tapes such as Velcro can also be used instead of the double-sided adhesive tapes.

5: Calibrate the Sensor

• The sensor must be calibrated to detect the floor before it can detect falls correctly. You need to redo the calibration if the angle or position of the sensor is changed. The sensor only sends alert when a person falls to the calibrated floor area. Falling on sofa, couch or bed will not trigger alert.
• To protect people’s privacy, make sure that nobody is in the view of the sensor during the calibration.
• Users must be within Bluetooth range of the sensor (~5m) in order to do the auto-calibration. Manual calibration can be done remotely.
• Power up the sensor. Go to the sensor page in the App, click Calibrate. If the sensor has not been calibrated before, the App will first show some instructions about the installation height and angle, and will ask users to select if the sensor is installed upside-down or not, and if the background image should be natural mode or privacy mode. After making these choices, press the “Begin Calibration” command will start the calibration.
• For the Cypress sensor, the calibration takes about 15 seconds. For the Sentinare 2 sensor, the calibration takes about 30 seconds.
• To ensure good fall detection performance, please ensure the sensor’s height and angle can capture a large area of floor. If the floor area is too small, a warning message will be displayed when you save the result to remind you to adjust the installation height and angle of the sensor.
• You may need to adjust the sensor position and angle in order to get good calibration result, before finalizing the installation. To update the calibration, tap the “Recalibrate” command, the sensor will take a new background image and detect the floor in it. After you can satisfied with the calibration result, tap the “Save” button to save the result and exit the page.
• Manual Calibration: Sometimes the auto-calibration algorithm may mis-calibrate some non-floor areas as floor, or miss some floor areas, which could cause wrong fall detection results. In this case, users can manually modify the calibration result using the editing tools in the Calibration page.

The following is a video demo of calibration using the private mode.

6: Add People (Optional)

• Some features of the Sentinare sensor rely on face recognition, such as collecting individual statistics of each person’s daily activities and face-recognition-based Region of Interest (unless the Detect Anyone option is selected). To enable these features, users need to add the head photos of people that need to be monitored by the sensor.
  • Note: Fall detection does NOT require face recognition.
• To add a person, tap on “+ Add Person” at the top of the “People” page. The App first needs to get a head image of the person from the mobile device’s camera or from the image library, as shown below.
• After getting a head image, the “Add Person” page will appear, where the user can input the name of the person and assign this person to a Person Group, such as Seniors or Staff.
• In the next page, users can add or delete photos for the person. In this page, users can change Person Group, and input the person’s detailed information.

For best performance, take the following photos of the head:

• Front view
• 45^o left and right views (with both eyes visible)
• 15^o top view

The entire head should be in the circle with both eyes visible. The photos should be clear, well-lit, without shadows or other people.

The following is a video demo of adding person to an account.

That’s it!

The sensor is now ready to look after your loved ones! It will monitor their activities, collect statistics, and send alerts when emergencies such as falls are detected. You can check their real-time activities, or review their activity history.

The following are some demos of other powerful features of the Sentinare sensor. Please refer to the User Manual for details.

7. Video Demos of Key Features for Senior Care and Patient Monitoring

1) Fall Detection

When the Sentinare sensor detects a fall, it will send an alert to the Sentinare app. The alert will include a short clip of stick figure animation to show how the person falls, and can help to identify if it is a real fall or a false alarm. If the name of the person is recognized (via face recognition), the name is also included in the alert and the stick figure clip.

2) Waving Hand Detection

If a loved one needs help from the caregiver, he/she can wave to the Sentinare sensor to trigger the waving hand detection alerts. The sensor’s LED will flash red for a few seconds, and then turn to purple and send the alert to the App. The alert sensitivity can be adjusted from the App (See the User Manul for details). The video below shows the results with low, medium, and high sensitivities respectively.

3) Region of Interest

Users can define various Regions of Interest, such that restricted region, overstay, and absence. This can be used to detect wandering of people with dementia, or bed exit/leaving of people with high risk of falling. Face recognition is required, unless “Detect Anyone” is selected.

4) Stick Figure Recording

The Sentinare sensor can record and play back all human activities in terms of stick figure animations, which provide valuable visual information while protecting the privacy of the person.

5) Personal Activity Statistics

When the face photos of a person are added to the Sentinare account, the Sentinare sensor can recognize different persons, and collect their individual activity statistics for playback and analysis.

6) API for Third-Party Integration

Using the API provided by AltumView (see Chapter 11 of our User Manual for details), other partners can get the real-time and historical data from the Sentinare sensor and develop their own algorithms and applications.

The following is a video to show how Dr. Bruce Wallace‘s group at SAM3 AGE-WELL National Innovation Hub use AltumView’s sensor and API to study gait analysis of seniors.
