RAK WisCam is the Modular Based Evaluation Kit to help the developer to design Wi-Fi video product with Linux OS. WisCam can transmit video through Wi-Fi to APPs. This document mainly describes the hardware structure of WisCam and how to use WisCam’s basic function. For example, play video in the mobile app or Windows program.
◆ High-CPU N32905R3DN is built on the ARM926EJ- 32-bit RISC CPU core. The frequency can be up to 200MHz@1.8V. ◆ Wi-Fi Access WisCam uses RTL8189FTV Wi-Fi chipset and it supports IEEE 802.11 b/g/n protocol, 2.4GHz Band, 1T1R antenna and SDIO interface. High-speed wireless connection can be up to 150 Mbps. ◆ Easy To Use Once you power on WisCam, you can play the video in mobile apps or Windows program. ◆ Open All Source Code All software source code is available on Github and you can download it.
◆ Arduino compatible RAK WisCam fully compatible with Arduino UNO development board in hardware so it can extend your application with Arduino UNO. ◆ P2P Cloud Server WisCam also has integrated the P2P cloud server(Nabto P2P) to make playing the video anywhere when you access the internet . The mobile APP(Android and IOS) can play the video and interact bidirectional audio between WisCam and APPs. ◆ Video Recording WisCam can record up to 640x480@30FPS RGB MJPEG video. ◆ UART for development WisCam provides UART interface to communicate with Host MCU or Arduino board. This allows you to focus on your application development. ◆ Mobile APPs WisCam provides the source code of mobile app to discover the device and play video. Source code is available on github
◆ Rich Peripherals WisCam provides a 10-bit ADC, a MIC-phone, a UART, a speaker and a dozen of GPIOs(the number will change with different Sub-Board). ◆ Multi- Accessories WisCam also provide accessories to make your application more amusing and easier to use. Sub-Camera and Sub-SD&USB are the critical parts in your application. Sub-Camera is using for collecting the image sensors and play in APPs via Wi-Fi. Sub-SD&USB is using for USB storage or UVC function and more accessories will be available in the near future.

WisCam has 2 modes as following. 1) UVC(USB Camera) The UVC mode is activated when the WisCam board is connected to the PC via a USB cable. You can see the video with UVC capture utility. 2) Wi-Fi Camera: Power supply from the Arduino board. WisCam board has Arduino pin header form factor so connect it to the Arduino board and supply the power to the Arduino board. Then the Wi-Fi AP works and you can connect it with your mobile phone and see the video streaming via Wi-Fi.
4.2 Compile Source Code 1 Download source code: https://codeload.github.com/RAKWireless/WisCam/zip/master or git clone https://github.com/RAKWireless/WisCam.git 2 cd WisCam 3 sudo chmod -R 755 ./ 4 ./scripts/build.sh
4.3 Burn Firmware
1) After Compile, Copy output/autowriter_gc0308 to your windows PC. Or Download the factory firmware from github: https://github.com/RAKWireless/WisCam/blob/master/Wiscam%20Factory%20Firmware%2020170504.zip
2) Connect BOOT PIN to GND. 3) Connect Wiscam to Windows PC with Micro-USB Cable. Then Wiscam’s power is turned on and operate in Recovery(Boot) mode.
4) Execute AutoWriter.exe in folder autowriter_gc0308 and the select Current Target as SPI then WisCam will burn firmware automatically. If the Status is “Burn Success…….”, the burning is completed.
WisCam support RTSP (Real Time Streaming Protocol) video and audio stream and it have Nabto P2P cloud server, Telnet and UART transparent transmission. Connect the WisCam board to the Arduino board and supply the power to the Arduino board. Then the red LED is turned on .After 5 seconds, blue LED is blinking. After 30 seconds, you can connect the SoftAP with your mobile phone.
Default Configuration: Power on as SoftAP; Default SSID: WisCam+MAC address, For example: WisCam-3a-1d-d9-7b-3a-15 Default Password:12345678 Default Gateway IP: 192.168.100.1 Default Subnet Mask: 255.255.255.0 Video Encode Format: MJPEG.

==== 5.2 Remote video in WiFi Mode ====
1) Nabto Overview
Nabto platform provides direct real-time connectivity with no firewall
or dynamic IP hassle and control the embedded devices directly from
HTML-in real-time or stream data directly to and from device.
Now nabto start by default with no password, so you can change nabto
id and password through “nabto” command.
You can get the nabto ID with http command.Please use your PC or
smartphone to connect the wiscam’s Soft-AP , then open the broswer
to input the link (command) to get the current module’s Nabto ID :
Then add the id(lx520…) in the picture is just for test,
you can change it though http command
&nabto_id= lx520.xxxxxx.rakwireless.com &Nabto_key= xxxxxxxxxxxxxxxxxx)
or change /mnt/nand1-2/etc/nabtonat_config in your
terminal(For more information, refer to the Program Guide).
Note: If you need new Nabto ID to test , please contact this email
firstname.lastname@example.org to get new ID.
2) Download APP
If need to test the remote function ,you have to download a new APP for testing .
https://www.pgyer.com/rakvideotest Search RAKVIDEO in APP STORE
3) Add Remote Device
Input the nabto ID to Add remote device. And then select software decode(surfaceview),
MJPEG Format and default password admin.then you will play the video in APPs.
(the following picture is from android APP).
==== 5.3 UVC mode ====
WisCam supports UVC (USB Video Class) mode.
1 Connect the board to the PC using micro USB cable. The Power RED LED
will light and Blue LED will be off all the time .
2 The board will reboot and Windows UVC driver will be installed automatically.
3 You can see ‘NUWICAM USB UVC Device’ in device manager Windows.
4 Open UVC capture utility to test UVC function. For example, “WebcamViewer” or “AMCap”
