What does STACKABLE mean?
Many DVR cards are NOT stackable. When you purchase a four channel card that is NOT stackable, if you decide to upgrade to 8 cameras, you have to take the four channel out and buy an eight channel card. A Stackable card allows you to simply add another card, thus saving the old card and it’s associated expense. Our Geovision cards are NOT stackable, Our H Series and our DV Series Cards ARE Stackable.
