Hey guys, installing your own doorbell is very simple now. Thanks to DIGOO DG-SD20 Self-powered Wireless Doorbell. It is using 433MHz wireless protocol that works for long-distance. Multiple plugs available. Mine is UK one. Here is the self-powered transmitter. No battery is needed. And it is waterproof as well…



That's all. Thanks for watching...
