LNWDB1 - Troubleshooting

The following are some of the most common issues and troubleshooting tips for the Lorex doorbell.

Doorbell is not turning on because of low voltage.

After restoring power, please wait for up to five minutes for the device to power up its capacitors before the doorbell is ready. When it is, it will emit the start-up chime, and light up.

Try using a spare a micro USB cable to power the doorbell via the micro USB port at the back (the port is hidden under a black rubber sticker above the doorbell contacts) to ensure the doorbell powers up, and can connect to Wi-Fi. Take note that you will have to remove the doorbell from its mount to do this process.

Ensure your doorbell wiring provides the minimum required voltage. Some houses do not provide the minimum required 16-24 VAC, so please consult a licensed electrician if you do not know how or do not want to do this.

If you do not have a 16-24 VAC transformer, we recommend that you purchase one at your local hardware store and get the services of a licensed electrician to install the transformer.

What happens when the doorbell receives too low voltage?

  • Doorbell hotspot will not work.
  • The reset button will not work.
  • It will show the blue LED as solid then will keep flashing while it cycles -- watch it here.

What happens when the doorbell receives the proper amount of voltage?

  • You will hear a sound.
  • You will see a pulsing blue light and running light on the LED ready to connect -- watch it here.

Chime does ring or it sounds abnormal.

When the doorbell button is pressed the chime is holding the ding sound, check the chime cabling or it may be pushing on some wires or connector and interfering with the moving parts. Check the Chime Setting options on the Lorex Home app as well.

I hear an echo when I use 2-way talk (iPhones Only)

Users experiencing an echo or other audio issues, should upgrade their iPhone firmware to iOS 16.1 or later.

Doorbell is not connecting to your Wi-Fi network.

Check that the Wi-Fi network you are trying to connect to is on 2.4GHz. The doorbell only works with 2.4GHz. It does not work with 5GHz networks.

The doorbell is not connecting to the Lorex Home app during setup.

Please make sure you are using 2.4GHz network or that the doorbell is not too far away from the router.

If it is the case, you may have to purchase a network range extender.

The Wi-Fi connection is weak.

If you’re getting lots of camera offline notifications, this usually means your camera doesn’t have a consistent Wi-Fi connection. It’s likely disconnecting, then reconnecting.

We highly recommend getting a network range extender to boot your doorbell coverage.

I am getting too many Push Notifications.

Please check if the notification is on in both the app and phone settings.

The doorbell is picking up too much motion.

If the doorbell is picking up more motion, you can adjust the Motion Sensitivity on the Lorex Home app.

The doorbell is picking up motion more than the front door.

If your doorbell is picking up more than the front door, you can adjust the distance of the PIR detection on the Lorex Home app.

The doorbell is offline and does not appear to reconnect.

  • Check if your doorbell is receiving power.
  • Check the LED indicator. If it is flashing blue, then the unit failed to connect to the network. If it is, go to the Lorex Home app and reconnect the doorbell to your network.
  • Restart your doorbell.
  • Restart your router.
  • Factory reset your doorbell.

There's a delay or lag in the video and people can't hear you speaking through the camera.

If you're using a cellular connection try moving to an area with a better reception, or connect to your Wi-Fi network. If your Wi-Fi signal is also weak, go to an area where the signal is stronger.

Your camera's Wi-Fi connection may be weak in the spot where your doorbell is mounted. Try moving your router closer to your camera or install a network range extender near your doorbell.

How to restart or factory reset your doorbell?

  • To restart or factory reset your doorbell, remove it from the mount and locate the reset button at the back of the device.
  • Press the reset button until you hear the chime reset sound.
  • Set up your doorbell as a new devic on the Lorex Home app.

What is the minimum recommended upload speeds for remote video streaming?

We recommend 3.5 Mbps or higher.

Can you replace the 16 GB micro SD card with a larger card?


You can upgrade your storage up to 64 GB.

The doorbell is not detecting or not recognizing the SD card.

  • Please format the SD card into FAT32 on your computer, and then insert the SD card into the camera to see if it works.
  • The card had not been properly inserted into the camera. Take out the SD card and insert it again to see if it works.
  • The SD card is defective. Please test the SD card on your computer and see whether the SD card can be read and written. If it doesn't, please use another SD card to see if it works.

If you don't already have an existing doorbell.

You will need to buy a power supply and a chime box.

Incompatibility with specific chime box, or doorbell is repeatedly ringing.

You may have forgotten to link the chime, install the chime box, or may have selected the wrong chime box type.

Please take note that mechanical chimes have moving components, and a classical “ding dong” sound as you hold, and then release the doorbell (so that when you press, the doorbell will produce a classic “ding” sound and when you release it, the doorbell will produce a classic “dong” sound).

Electronic chimes do not have moving components, and can use other sounds.

Hotspot connection issues with the mobile device or the Lorex Home app.

  • Ensure location access is enabled for the app.
  • Do not use a VPN.
  • Double-check Android 10 because OS may block no password network.
  • Try manually selecting the doorbell’s Wi-Fi hotspot in your mobile device’s settings.

If you encounter the following issues, please reset the doorbell and try to setup again.

  • You can see live video but the chime is not ringing.
  • You are receiving push notification but not receiving any video in live view.

Does Lorex doorbell work with WPA3 router?

At this time, the doorbell does not support connecting to a WPA3 router. If possible on the WPA3 router, you could change the encryption type to WPA2/WPA.

What are the compatible SD cards?

NOTE: The doorbell requires a Class 10 SD card.
