Hello everyone, I am new in the forum. 
I just bought a dvr economic: cctv  model: tk-d8c8 ; 8 channels. 
in the instruction manual I read about the snapshot menu. 
in my dvr does not really exist the menu snapshot. 
I would be comfortable sending photos via email. 
the rest is all set:  
-I get emails (no photo  ) 
-I partitioned the hard drive and the second partition has been recognized by the system as partition snapshot! 
-the motion detection works fine, and starts recording or cyclic function on the monitor. 
  
do you think I should upgrade the system? where can I get the file for the upgrade? 
  
this is my instruction manual: 
  
  
this is my motion detection menu: as you can see, it lacks the snapshot feature! 
  
  
Thank you for your attention.
