Due to Google Data APIs upgrade, newer libraries would be required to update in our firmware.Or you may not upload recording videos to the Google Drive; your mobile App may not playback recording files downloading from Google Drive disk. New firmware is coming soon…
Sorry for the inconvenience.

由於舊版Google API即將於2015年4月20日起失效，強烈建議您更新PB731攝影機至最新版韌體，否則會遇到無法將錄影檔案上傳至Google Drive、或是手機App無法撥放Google Drive雲端硬碟上錄影檔案的異常錯誤。對於給使用者造成的諸多不便，我司深感抱歉。
