If your home or office network already uses the IP address 192.168.1.1, it is cumbersome to send the THETA commands from your workstation or laptop. Although it’s possible to set up a separate router for the THETA, you can also use a cheap USB dongle to provide a Wi-Fi hotspot that your THETA V can connect to. In the following example, my workstation is connected to the Internet with Ethernet and using an AT&T U-Verse router with an IP address of 192.168.168.
I am sharing the Wi-Fi dongle with my RICOH THETA V and sending OSC commands from my workstation to the THETA V using client mode Wi-Fi. The Wi-Fi adapter I am using is currently $14.99 on Amazon.
- Kiosk PC is connected with Ethernet to Office Network Switch at 192.168.1.1
- Office Network Switch supplies Internet access to office network and Kiosk PC
- Kiosk PC has Wi-Fi adapter that supplies Wi-Fi connection only to RICOH THETA V
- Wi-Fi adapter on Kiosk PC is assigned IP address of 10.42.0.1
- RICOH THETA V is assigned IP address of 10.42.0.181 by Kiosk PC
- Kiosk PC sends commands to RICOH THETA V using client mode digest authentication
Note on Security
This example shows an optional level of security that prevents all devices on the Wi-Fi network from accessing the Internet or any device on the office network. This level may not be needed in most applications. The default level of security uses WPA passwords.
Important Notice on No Warranty
This example is provided by the online community and comes with no warranty. Anyone following this example is responsible for testing the security and stability of the configuration themselves.
This example shows the basic concepts for secure client mode communication with the RICOH THETA. This example does not identify specific software on Windows or Mac to implement the system. To show the concepts working, I’m using Linux. Windows configuration should be similar.
In this setup, the Wi-Fi adapter on the Kiosk PC is only connected to the THETA. The Wi-Fi card is not connected to the Internet. The Kiosk PC gets Internet access through a separate Ethernet adapter.
Turn On Wi-Fi Hotspot
In Wi-Fi settings, click on the hamburger menu to the right of the “On” slider. Select “Turn On Wi-Fi Hotspot…”
Configure THETA V Client Mode
Use RICOH mobile app to configure RICOH THETA V in client mode. This is a one-time configuration. With THETA connected to the official RICOH mobile app.
Press the camera Wi-Fi button until it turns green. It will connect to the Kiosk PC.
Find IP address of camera
$ arp -n
Using zeroconf network discovery.
Send OSC Commands to RICOH THETA
Must use Digest Authentication.
Securing Network Between Kiosk PC and THETA V
This prevents any traffic on the Wi-Fi network from going out to the Internet or accessing any device on the office network.
This example uses iptables to delete the FORWARD routes.
In this example, I am using an Android device that I’ve connected to the Kiosk PC with Wi-Fi using the SSID and password that the THETA is using. The Android device was assigned the IP address of 10.42.0.55.
List iptables with line numbers
$ sudo iptables -L --line-numbers
$ sudo iptables -D FORWARD 1 $ sudo iptables -D FORWARD 1 $ sudo iptables -D FORWARD 1
Test That Kiosk PC Can Still Send THETA V Commands
Test That Devices Can’t Access Internet
Device is on Wi-Fi network, but can only talk to Kiosk PC
The script was tested by taking several hundred pictures and then downloading the pictures.
To help with testing, you can download the last 20 images with
$ client-mode.py downloadTester
You can take 10 images with
$ client-mode.py takePictureTester
If your PC kiosk is using Linux, you can hide the SSID broadcast with hostapd.
There doesn’t appear to be a way to do this with Windows 10.
