The Wireless Chime is an indoor standalone doorbell that rings when your outdoor video doorbell is pressed. This can be used in conjunction with the DH-DB6I or LincX2PRO DHI-DB11 doorbells from Dahua. You can add personal touches to your security system in addition to functionality by customising your chimes using the DMSS programme. You can connect the Wireless Chime to numerous video doorbells simultaneously for increased convenience, so you'll never miss a guest no matter where you are in your house.
