Hikvision DS-kV8113 , not enough power/voltage to doorlock/eletric strike

Hi Smati, thank for your reply, but this solution is not applicable for me. Theoratically the integrated relay (my is HFD4/5-S) can support 12V AC but it's not certificated, so i've added a step-down adapter 12VAC to 5VDC with an additional low triggering relay and connectet it to the door lock
