tkpete12 0 Posted November 7, 2016 I have a HikVision DVR 16 camera system. I have a car wash and want to control 8 doors. There are only enough relay outputs to control 2. It takes 2 relays to control 1 door. Is there any way I can add more relay outputs to control more doors? Any suggestions would be appreciated. Share this post Link to post Share on other sites
kindhop 0 Posted November 10, 2016 not sure if this will help but what would be the possability of dubbeling the zones and buy that what i mean is have more then one door on one acces control like say bay one auto Car wash enter exit on one loop things like that now my experience tells me not possible but i could be wrong and welcome learning how i might be wrong Share this post Link to post Share on other sites
