No batteries, easy install and guaranteed for 10 years. Each tag is read by the visitors phone and notifies you, with an option to contact them via text or video call. With standard video doorbells you only get one place for callers to contact you. With doortagg you can install multiple tags in different locations and you can be called from many different places.
Doortagg is also far more interactive than a simple video doorbell. You can choose how you want to contact your visitors, deciding how to deal with them at the time.
You can let them know you're coming with one click. If you're busy, request a message from them so you can decide if it is important. In or out, you can initiate a video call or send a simple chat message.
All these options allow you to screen your callers and interact in different ways depending on your requirements.
