Requirement Power 10-30VAC, 10VA or 12VDC, 0.5 to 1.0A wired to an in home mechanical or digital doorbell chime. Note: A Digital Doorbell Adapter must be installed if a digital doorbell chime is present. WARNING: An in-line resistor (10 Ohm, 10 Watt) is required when installing the doorbell camera without a wired, in-home doorbell chime. This is typically done when testing the doorbell or performing a demonstration. Failure to install a resistor when a chime is not present may result in damage to the doorbell camera. Chime Security Panel (XP02) as Chime - XP02 Panel can be a chime of the EZ-Bell doorbell. Mechanical Chime - If the chime has metal bars and a striker pin, it is mechanical and will work without additional hardware. Digital Chime - If the chime has a speaker that plays a tone when pressed, it is digital and will require the installation of the Digital Doorbell Adapter and the enabling of the digital doorbell setting in the app to function properly. Tube Chime - If the chime has a series of tubular bells, it is a tube chime and is incompatible with the doorbell camera. Intercom System - If the doorbell button fixture includes a speaker, it is an intercom system and is incompatible with the doorbell camera. No Chime - If there is no chime in the system, the customer will only receive alerts on their phone and a resistor (10 Ohm 10 Watt) must be used in-line with the doorbell camera. WiFi A Wi-Fi Internet upload speed of at least 1.5 Mbps is required at the location where the doorbell camera is installed. Note: In Canada when using 5 GHz on band 1, the device is intended for indoor use only. Confidential for D3 Internal Use Only 3 7. Hardware Installation 8.
