need high speed playback of recorded video

We need high-speed playback of recorded video on SD card. Presently, it is almost impossible to find a short episode (like someone passing by your front door) from recorded history

Hi @ANOUR, check out this FAQ"s page on SD card playback, maybe it can help you. You can insert your SD card into your computer to see individual files, or you can change your settings to activity detection recording to only record activities. Hope this helps!
