I personally own 2 systems at my 2 ajoining washes.... both very different! The first system I bought and had installed "professionally" wit h my alarm system & fire system in my FS tunnel before I started reading the ACF 6 years ago. I paid over $16,000 for the system with the alarm.... not including the DVR that I paid an addition $3000 for! Last year I bought an 8 camera system with a DVR from Allen Spears for my 5 bay SS for $4500! I rocks compared to the other system.
