Carl R. (Los Angeles, CA)
High quality construction, works great.

I have installed as main gate access controller. The device is used for gate access via keypad and house call via the ring button. Setup is easy, app driven setup. Works great and love the design. It looks professional versus the other brands made of plastic that look more like toys.

Danny L. (Los Angeles, CA)
Great unit, works very well

I have been using the Doorbird for about 7 weeks now. The unit comes complete with with cables and miniature connectors for Ethernet, power, lock, doorbell, etc. And snap connectors. Was easy to install and operate.

The finish is beautiful, I love how they had so many color options to choose from. The Bronze looks great with our new home.

Home Outlet Direct shipped quickly and made the purchase easy. I recommend for any home that requires this type of security.
