HOW THE SYSTEM WORKS

Works Independently

This video doorbell can work independently once it is connected to your home wireless router. You can receive notifications and hear a ring when someone presses your video doorbell through various options:

• Use a traditional doorbell chime (if you have one).
• Use a eufy Security doorbell chime (sold separately).
• Use an Amazon Alexa Echo Show device.

Works with eufy Security HomeBase (Optional)

The video doorbell detects motion at your porch and allows you to answer the door anytime, anywhere. Video clips can be stored in the built-in storage of your eufy Security HomeBase 2 or S380 HomeBase (sold separately). When someone rings the doorbell, people in the house will be notified.

2. Fully charge the rechargeable battery pack before installation. [Illustration: USB-C cable connecting to the battery pack and a power source.]
3. Place the battery pack into the battery compartment. [Illustration: Battery pack being inserted back into the doorbell.]

SETTING UP THE SYSTEM

1. Download and install the eufy Security app, then sign in or create an account. [App Store and Google Play logos shown.]
2. Follow the in-app instructions to add the video doorbell. [Illustration: Smartphone displaying the eufy Security app interface.]

DETERMINING THE POWER OPTION

Option 1: Battery Powered

If you don't have existing doorbell wiring at your front door, use the included battery. You can determine the location of the doorbell freely, making mounting easy and quick. When the battery is low, you will need to recharge it. Battery life varies with use. If you choose this option, skip to DOORBELL MOUNTING (Battery Powered).

Option 2: Wire Powered

If you have existing and working doorbell wires at your front door, the video doorbell will be constantly powered by these wires. There is no need to detach and recharge after installation. The mounting position is limited. If you choose this option, skip to DOORBELL MOUNTING (Wire Powered).

DOORBELL MOUNTING (Battery Powered)

Choose a Location

1. Take the video doorbell to your front door and check the live view in the app. Choose a location where you can see the desired field of view. Consider the following factors:

• Check if you can reuse the existing holes and anchors in the wall or door frame.
• If you want to place the doorbell near a side wall, make sure the wall isn't in the field of view. Otherwise, the IR light will be reflected and the night vision will be blurred.
• If you are drilling the mounting holes for the first time, the recommended height is 48" (1.2m) above the ground.
• To adjust the angle, use the 15° mounting wedge as a supplementary mounting bracket.

2. Place the screw hole positioning card against the wall to mark the location. If mounting on a hard wall (brick, concrete, or stucco), use a 15/64" (5.95mm) drill bit to drill 2 holes through the screw hole positioning card.

You can purchase an extra battery pack for quick replacement.

DOORBELL MOUNTING (Wire Powered)

Check the Doorbell Wires

1. Ring the existing doorbell to check if it is working. If it doesn't ring, your doorbell wires may be defective. Power on the doorbell by the built-in battery or consult an electrician to repair the wires.
2. Shut off the power at the circuit breaker. Turn the lights on and off to make sure the electricity in your home is properly shut off. [Illustration: Circuit breaker panel with a breaker switched to OFF.]

Always be careful when handling wires. If you're not comfortable installing it yourself, have a qualified electrician to do it.

Detach the Existing Doorbell Button

If you already have existing doorbell wiring:

1. Remove the existing doorbell button with a Phillips-head screwdriver (not provided). [Illustration: Screwdriver removing a doorbell button.]
2. Pull the two wires out carefully when removing the existing doorbell. Straighten the wire ends if necessary. [Illustration: Wires being pulled out from the wall.]

Choose a Location

1. Take the video doorbell to your front door and check the live view in the app. Choose a location where you can see the desired field of view. Consider the following factors:

• Check if you can reuse the existing holes and anchors in the wall or door frame.
• If you want to place the doorbell near a side wall, make sure the wall isn't in the field of view. Otherwise, the IR light will be reflected and the night vision will be blurred.

Connect the Wires to the Doorbell

Connect the wires to the terminals on the back of the doorbell, then tighten the terminal screws. Wire can be connected to any terminal.

[Illustration: Wires being connected to the terminals on the back of the doorbell.]

Important Notes:

• To prevent short-circuiting, make sure the wires are not touching each other after connecting them to the terminals.
• If the wires are too short, use the extension wires and wire nuts to make them longer. Use electrical wiring tape instead if there is no more space on the wall for wire nuts.

Install the Doorbell

Align the doorbell with the bottom of the mounting bracket, then press the top of the doorbell into place until it clicks.
