Connecting With App

Why is the Lorex App not connecting to the video doorbell during setup?
After you’ve scanned the doorbell’s QR code using the Lorex App during setup, the app attempts to discover your doorbell on the same Wi-Fi network that your phone is connected to. Since the doorbell connects to 2.4 GHz or 5 GHz Wi-Fi networks, during setup you must connect your phone to the same Wi-Fi network.

What’s the wireless range of the video doorbell?
Your 2K Wired Video Doorbell can only connect to a 2.4 GHz or 5 GHz Wi-Fi network. Many routers broadcast Wi-Fi networks in both 2.4 GHz and 5 GHz bands. During setup, connect your doorbell to the same Wi-Fi network as your phone.

Why is the video doorbell not turning on?

Check if the voltage is printed on your doorbell transformer and/or use a multimeter to test the power. Refer to the article “What transformer should I use with the 2K Wired Video Doorbell?” for more information.
Connect the video doorbell using the supplied USB power cable.
Make sure the USB cable is connected to a 5V 2A USB power adapter (not included) that is also connected to a power outlet. To verify if the power outlet is working properly, try connecting another device to the outlet and check if the device gets power. If the video doorbell successfully powers on using the USB power adapter, carefully go over the installation setup again. Refer to the article “Installing the 2K Wired Video Doorbell” for more information.
Select the correct option when connecting a Wi-Fi Chimebox. (ACCHM1 /ACCHM2)
During setup, select Not Now. Do not select Mechanical Chime or your doorbell will not power on.

Why is the video doorbell’s chime not working?

For your chime to ring, the chime setting in the Lorex App must be set to Electronic Chime or Mechanical Chime, depending on the type of doorbell chime you have. Mechanical chimes make a traditional ding-dong sound when rung while electronic chimes can play a melody or ding-dong when rung. You can modify these settings at any time in Device Settings > Doorbell Chime.
Check to make sure that the chime kit is wired correctly. Refer to the article “Installing the 2K Video Doorbell” for more information.
Allow for the video doorbell to power on for 5 minutes before testing the chime.
If after you press the ring button on the video doorbell, and experience that your existing mechanical chime does not ring, or rings continuously, please contact support at 1-888-425-6739.

Receiving Notifications

How come I am receiving so many notifications?

There are a few ways you can lower the number of notifications you are getting. The first settings you can look to adjust is the Motion Detection Settings. In here you can enable/disable motion detection and person detection, as well as customize Motion Zones™ and Sensitivity. Refer to the article “Customizing Motion Detection for the 2K Video Doorbell” for more information.
You can also manage notifications in Device Settings > Notifications and set a schedule to receive alerts at set periods in the day.

How do I customize motion detection and person detection?

Open the Lorex App.
Tap on the three dots ••• icon on the top right of the video doorbell (Device Settings) > Motion Detection Settings.

Note:
The 2K Video Doorbell has person detection and motion detection enabled by default. If motion detection is disabled, person detection will automatically disable and you will not receive any motion detection notifications in the Lorex App.

Recorded Events

How do I filter through recorded events?
The 2K Video Doorbell has person detection and motion detection enabled by default. You will only receive notifications in the Lorex App when a person is detected and your events will only display person detection events and doorbell call events.

Open the Lorex App.
Tap the video doorbell to go to Live View.
Tap on Timeline to reveal all events on the timeline bar.
Tap the three lines on the top right of the timeline to filter through the event types.

Link the 2K doorbell with sensors

How do you link the 2K doorbell with sensors?
A Wi-Fi camera or doorbell that is linked to a sensor will automatically start recording events whenever the sensor is tripped by motion.

Prerequisite:
To link Lorex Sensors to the 2K Video Doorbell on the Sensor Hub, you will need to first set up the Sensor Hub, the Door/Window Sensor and/or Motion Sensor, and the 2K Video Doorbell, all on the Lorex App.

Refer to the article Lorex Sensor Hub and Sensors – How to set up for full instructions.
Refer to the article Wi-Fi Security Camera – How to add or remove devices for full instructions.

Tap the three dots ••• icon next to the sensor hub to see a full list of connected sensors.
Devices > Sensor hub > three dots
Tap the sensor that you want to link to the doorbell.

The linked doorbell will automatically start recording whenever the sensor is tripped. To learn more about sensors, refer to the Lorex Sensor Hub and Sensors – Frequently Asked Questions.

Disable And Enable HDR

How do I disable/enable HDR?
High dynamic range (HDR) is optimized for outdoor environments to help with over or under-exposed images of scenes with both bright and dark areas in the same picture. Your video doorbell is enabled by default to determine when to use HDR, but you can disable it. This change takes effect on the next video stream or motion recording.

Open the Lorex App.
Tap on the three dots ••• icon on the top right of the video doorbell (Device Settings) > Video Settings.
Disable/enable HDR(High Dynamic Range)

Aspect ratio of the video doorbell’s image

What is the aspect ratio of the video doorbell’s image?
The video doorbell captures visitors from head to toe with an aspect ratio of 4:3 in vertical view.

Can the video doorbell be used inside an office building?
Yes, the video doorbell can operate in an office setting using the included USB cable. Since it will not be able to connect to a chime box, it must be set to an electronic chime in the Lorex App.

Important:

Do not use the USB cable while the video doorbell is wet or in an area where it could get wet. The protective charging cover on the back panel will be exposed to liquids which can result in damage to the charging port.
Make sure that the USB cable is connected to a 5V 2A USB power adapter (not included).
