I return to my log today, because I have just realized that recordings made by the camera either on site or on the samsung sD card are not in 640x360 but HD1080 which is quite insufficient for able to make facial recognition.
The video we see little on the samsung site Instant is adjustable in 3 definitions whose HD1080 but not recordings.
In my use I use the Blue Iris software to record all the videos and RTSP video stream is in HD 1080 for this camera, so images I record on my PC are usable, but if one is not in this configuration and that it relies solely on the SD card or the Samsung server that is not enough.
So you tell me why my lower rating because my videos are way HD1080, just if you come rob me and steal my PC the videos recorded on SD cards will be of no use for me unusable.
