checho2222 0 Posted May 13, 2011 Hi guys! This is my first post in the forum, I'm looking forward to install a CCTV system at home and i've found two different AVTECH DVR's about the same price, but after reading the specs line by line I couldn't find any difference between them! Its MDR751 and KPD674... which one should I buy!?! Thanks in Advance! Mariano Ps: In case of any mispelled word, on my defence, let me say I'm from Argentina! Hahaha....
