Q: What kind of phone must I have?

A: Any smart phone using the IOS or Android operating system. Some examples are iPhone, Samsung, HTC, or Motorola mobile devices.

Q: How is this product different from skybell and doorbot regarding WiFi issues?

A: The GBF IP Doorbells use an external WiFi antenna. This enables the use of a higher gain antenna as the size is not restricted by the product case, as is the problem encountered by products with ‘built-in’ WiFi antennas. The high gain antenna can easily be hidden in the wall cavity behind the GBF IP Doorbell or mounted in a location anywhere the 5 foot antenna lead will allow.

Q: How many maximum users (phones) can be connected to this door phone?

A: The software allows for up to four concurrent connections, although the first mobile device to establish a connection (answer the doorbell) will have control of the conversation. The other users can connect and monitor both the picture and the conversation. We have not realized a practical limit to the number of mobile devices registered to a single IP Doorbell.

Q: Will any standard door lock will work with this system? I have a door lock which specification says : Working Voltage: 12 VDC, Required Power: 12W.

A: The GBF IP Doorbell will work with any electrical door lock or gate controller requiring either a normally open or normally closed relay contact closure for operation. The relay activation time can be programmed for any duration from 0 to 99 seconds. The relay contacts are rated for a maximum of 3 amps at 30VDC or 250VAC.
