RSL10 Smart Shot Camera
Getting Started Guide

Overview

The RSL10 Smart Shot Camera (SECO-RSL10-CAM-GEVB) is a complete node-to-cloud platform that enables smart image capture for portable, low duty cycle IoT applications including asset monitoring and security. Based on the RSL10 SIP and the ARX3A0 CMOS image sensor, the platform features multiple trigger modes including time, motion detection, and environmental sensor triggers (e.g., changes in temperature and humidity).

The RSL10 SIP serves as the processing hub of the camera, enabling Bluetooth® Low Energy connectivity of captured image and sensor data to the provided mobile app (available on GooglePlayTM, iOS®).

This guide provides initial instructions for using the RSL10 Smart Shot Camera and accompanying mobile application. For further information about the platform, refer to the platform’s User Manual (EVBUM2782).

Hardware Set-up

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

Installing the RSL10 Smart Shot Mobile App

In order to operate the board, download RSL10 Smart Shot mobile app from GooglePlayTM or iOS®. After installing the app, ensure that Bluetooth and GPS are enabled on your phone. Select the icon to launch the application. The following sections detail how to send images from the Camera to the app over Bluetooth Low Energy, as well as other functions of the app including sending wireless firmware updates (FOTA).

Capture Image

After the camera is connected, the app will switch to the image capture page in Figure 3. Select the Camera icon to instruct the camera to take a picture. The image from the camera is transferred over Bluetooth Low Energy and is displayed on the screen. To save the image on your mobile phone, select the middle Save icon. On an Android phone, the image is stored in RSL10Smartshot directory. On a iPhone, the image is stored in your Photos directory.

Capture Stream of Images

The camera also can capture stream of images with different frame rates. Select the Settings icon to switch from Single Image Mode to Stream Mode. You can also adjust the Frame Rate from <1 frame/second to 1 frame/minute.

Figure 4. Stream Mode

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 are used to trigger image capture when a change in value is detected.

To set or change the triggers, select the Settings icon. You can turn the triggers ON or OFF, and set the minimum and maximum thresholds of temperature and humidity sensors. You can enable either individual sensor or a combination of sensors to set your trigger condition for image capture.

Figure 6. 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 image for analysis is uploaded to the cloud engine, and results are displayed on the app. More information about the Amazon Rekognition setup is available in the RSL10 Smart Shot Camera User Manual (EVBUM2782).

You should specify your AWS account credentials to use this feature. Select the Settings icon -> AWS Account on the Home Screen.

Figure 8. 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.

To begin, you will need the following:

• Install the RSL10 FOTA mobile app (available on GooglePlayTM, iOS®).
• Download the smartshot_demo_cam.fota image file

Note: FOTA only updates the RSL10 image. To update the Image Sensor Processor firmware (SPCV1100A) refer RSL10 Smart Shot Camera User Manual (EVBUM2782).

To send FOTA updates to the RSL10 Smart Shot Camera, push the PB1 button on the platform. The green LED will light up, and your board will switch to FOTA Mode. The platform will then be discoverable on the RSL10 FOTA app.

Figure 10. 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 (PB_RST1). To return to normal operation, press the RESET button.
