RSL10 Smart Shot Color Camera
Getting Started Guide
Overview
The RSL10 Smart Shot Color Camera (SECO-RSL10-CAM-COLOR-GEVK) is a complete ultra-low-power,
event-triggered, node-to-cloud platform that enables smart image capture for portable, low duty cycle
IoT applications including asset monitoring and event-triggered camera. Based on the RSL10 SIP and the
ARX3A0 CMOS image sensor (color and mono), the platform features multiple trigger modes including
periodic intervals, motion detection, and environmental sensor triggers (e.g. changes in temperature and
humidity). The RSL10 SIP serves as the processing hub of the camera, and Bluetooth® Low Energy
(Bluetooth LE) connectivity enabling remote control and transfer of captured image and sensor data to
the provided mobile app (available on GooglePlay™ , iOS® ).
This guide provides instructions for using the RSL10 Smart Shot Color Camera and accompanying mobile
application. For further information about the platform, refer to the User Manual.
To get started with the platform, you will need:
•RSL10 Smart Shot Camera (SECO-RSL10-CAM-COLOR-GEVK)
•RSL10 Smart Shot mobile app
•RSL10 FOTA mobile app
•Amazon Web Services™ (AWS™) account credentials to use Amazon Rekognition™
Hardware Setup
The RSL10 Smart Shot Color Camera kit includes the baseboard PCB, two ARX3A0 IAS camera modules
and a USB cable. By default, the color ARX3A0 IAS module is mounted onto the PCB and the mono IAS
module is bundled with the kit. To use the mono IAS module, swap the module onto the baseboard PCB.
The firmware supports both module, and is capable of automatically identifying the modules. In this guide,
we will be using the color IAS module.

Figure 1. Unboxing the RSL10 Smart Shot Camera
To get started with the kit, remove the protective layer from the camera module and connect the provided
USB cable to your PC’s USB port (Fig.2).
A green LED, shown in figure 2 below, will begin blinking to confirm that the device is ready and in BLE
Advertising Mode.

Install the RSL10 Smart Shot Mobile App
In order to operate the board, download
RSL10 Smart Shot mobile app from GooglePlay™ or iOS®. After
installing the app, ensure that Bluetooth and GPS are enabled on your phone. The following sections detail
steps to capture images from the camera over Bluetooth Low Energy, set trigger events, perform image
analytics using AWS Rekognition and perform wireless firmware updates (FOTA).

Connect to the Camera
The home screen of the mobile app displays the RSL10 Smart Shot Camera as a discovered device.
Select the device to connect the camera to the mobile app (fig. 4).

Capture Image
After the camera is connected, the app will switch to the image capture page in Figure 5. Click the
Camera icon to instruct the camera to take a picture. The image captured by the camera is transferred
over Bluetooth Low Energy and is displayed on the screen. To save the image on your mobile phone,
click the
Save i con. On an Android phone, the image is stored in the RSL10Smartshot directory. On
iPhone, the image is stored in your
Photos directory.

Capture Stream of Images
The camera also can capture continuous stream of images with different frame rates. Click the
Settings
icon
on the top right corner and toggle the Mode option from Single Image to Stream . You can also adjust
the frame rate from <1 frame/second to 1 frame/minute.
Exit the
Settings menu by tapping the bottom of the screen. Click the Play button to start streaming
images, and click the
Stop button to stop.

Setting Event Triggers
The RSL10 Smart Shot Camera supports four environmental sensors, which can be used to trigger image
capture whenever a change in value is detected.
To set or change the triggers, select the
Settings icon . You can turn the triggers ON or OFF by toggling
the switch for each sensor. For temperature and humidity sensors, you can also set the minimum and
maximum thresholds values, and trigger an event when the sensors detect values outside the range. You
can enable either an individual sensor or a combination of sensors to set your trigger condition for image
capture.

Figure 7. Environmental Trigger Settings
Exit the
Settings menu by tapping the bottom of the screen. The RSL10 Smart Shot Camera will
be armed and capture an image each time event conditions are triggered. The captured image
along with the triggered event condition will be displayed on the screen.

Object Recognition using Amazon Rekognition
The mobile app uses Amazon Rekognition cloud engine to analyze the image and identify objects within
it. The captured image is uploaded to the cloud engine for analysis, and results are displayed on the app.
More information about the Amazon Rekognition setup is available in the platform User Manual.
You should specify your AWS account credentials to use this feature. Select the
Settings icon -> AWS
Account
on the Home Screen.
Figure 9. Accessing Amazon Rekognition

Enter the
accessKey and secretKey associated with your AWS account and click Use . After
logging in, you can use the
Face icon shown below to analyze pictures captured with the
RSL10 Smart Shot Camera.

Firmware over the Air (FOTA) Updates
The RSL10 Smart Shot Camera supports wireless firmware updates using the RSL10 Bluetooth 5 radio.
You will need:
•RSL10_SMARTSHOT_FIRMWARE_UPDATE_PACKAGE.zip
•RSL10 FOTA mobile app (available on GooglePlay™ , iOS® ).
•
•Unzip above package and download the
smartshot_demo_color_cam.fota image file to your mobile
To get started, unzip the RSL10 Smart Shot Firmware update package and download the
smartshot_demo_color_cam.fota image file to your mobile device.
Note: FOTA only updates the RSL10 SoC firmware. To update the Image Sensor Processor firmware
(SPCV1100A) refer to the
SmartShot Firmware Update Guide.html under
RSL10_SMARTSHOT_FIRMWARE_UPDATE_PACKAGE.zip .
The boards can be switched into FOTA mode by pressing and holding the on-board push button PB1
during normal operation over RSL10 FOTA mobile application.
This section describes over the air updates via RSL10 FOTA Mobile Application. Switch to FOTA mode is
indicated by 1 second long flash of LED. The platform will then be discoverable on the RSL10 FOTA app.

Figure 11. Switching to FOTA Mode
After selecting the device on the mobile app, you can update the firmware by clicking Select File to
import the new firmware. Click Connect and Update to send the firmware to the device.

Power Down Mode
In Power Down Mode, all systems are put into low power modes to consume the lowest possible amount
of power. Low Power Mode can be entered by keeping the on-board button PB1 pressed after releasing
the reset button. To return to normal operation, press the RESET button (PB_RST).
