@SFX_Group: GSC3570 is not NVR but a video decoding and displaying device, although it can record video (stored in SD card) but this feature is not available yet and will be in later firmware. ONVIF is not applicable here, but industry solution is using RTSP to decoing the video. This feature will be implemented in later firmware either.
The customized UI/icons in the screen feature will also be in later firmware. We are collecting feedback from field to improve this new product.
Thank you very much for your testing, feedback and support.
