Hallo everybody, 
yesterday I've bought my first Avtech AVC760 (version #3). I've read many times this forum and  the wonderful scorpion's site, so I decided for this model.  
I live in Italy, that means PAL, and my recording values are: CIF: 352*288 - Frame: 720*576. Firmware: 2.0.2.0 
  
I've many questions...: 
  
1) First of all: I can't delete any recording, isn't it? Why?  
The problem, for me, is that with motion detection I've many "false alarms" and I'd like to remove them. I suppose it isn't possible. 
  
2) When I press the play button and the playback starts, which recording is shown? The last ones? Can I switch among the "markers" of the recordings or should I navigate in the long "tape" of the DVR? 
  
3) When I choose "Frame" the DVR records the single channel, but when I choose "CIF" it records a 720*576 frame divided in the 4 channels ! All the 4 channels are recorded, so if ch.2 has triggered the motion, all the others are recorded as well. If I set "Frame" instead, the DVR records the single channels. 
That means a very different  behavour of the DVR. 
  
4) The ftp alarm: the DVR makes only a snapshot of the screen: the file uploaded is a 320*276 jpg with everithing of the "moment" (OSD, aspect, ...). I'd like to upload the single channel of the motion detection, so I tried to activate the "sequence" and it works sometimes...  
I read that the ftp alarm makes a backup of the video in the path. It's so? I can't see them anywhere. 
  
5) Cant' I see in the HDD list the dimension, duration of the recordings? 
  
6) My camera records an entry door in backlight. I must choose the motion values correctly to avoid as many false alarms as possible. Have you a link to explain in depth some values of them? 
SS: means the dimension of the object that triggers the alarm? 
RI: is the movment of the object? 
  
Many questions I know... thanks in advance.
