2 Way Wireless Voice Intercom Doorbell with Built-in Speaker, Home Security Access Control System with 6 Months Standby Time, Door Bell

I really liked it but then it quit working. Very disappointed.

Worth buying

No duro ni una semana

Funciona para lo que describe, es decir, que alguien toque el timbre y tu le respondas algo ( solo si se activa el timbre primero puedes hablar, si nadie toca el Timbre tu no puedes activar desde dentro el speaker) la calidad es pobre, el sonido se escucha con poco de interferencia. No puedes bajar el Volumen, ni cambiar tonos Funciona pero es caro para lo que entregan

We used this as a temporary intercom while my mother-in-law was recovering from surgery. Worked great! Did not install permanently. Sound was good and the bell chime was nice getting our attention that she needed anything:)
