To be able to view the cameras, you will have to configure it in QVGA mode and connect through WiFi. This mode provides fastest speed of image acquisition. It's not specified the devices or cameras supported, but in case you have problems accessing cameras, I recommend sending an email to the developer. He will ask about logs to fix the issues, so make sure you have the File Manager ready to follow the instructions.
