I already have one Dahua DHI-DB11 wired to my electronic chime (chimekit being used) and connected through wifi to my NVR for security; work fine. My question is I have purchased another DB11 for the back door. When I connect to the electronic chime do I need another chime kit connected in the circuit for the back door. Is it wired to the "trans" connection then doorbell? Thanks, Wil
