lorex cannot find network host

Lorex cannot find a network host? We have a lot of ideas to fix that! Lorex is very convenient, but some errors can happen.

The network host error involves energy outages and settings that prevent the system from communicating correctly. 

If Lorex cannot find network host manage the IP settings and reconfigure your cameras. Moreover, update the devices involved and check if the physical installation is fine.

Lorex Cannot Find Network Host – Learn 8 Solutions!

Solution #1: Configure The Camera To DHCP Reservation

When you get the message “Cannot Find Network Host” on Lorex, one of the culprits is the IP configuration.

The IP can change when your camera is connected to power using Ethernet and there is a power outage or any issue with the power feed.

Dynamic Host Configuration Protocol is necessary to keep the cameras connected in such events.

DHCP Reservation For LHB Series

If your system is LHB series, you need to follow these steps:

  1. Access the NVR/DVR system.
  2. Locate the taskbar.
  3. Click on the Home icon.
  4. Go to “Settings.”
  5. Click on “Network” and “Network” again.
  6. In the network tab, select “DHCP.”

DHCP Reservation For LNR/LHV Series

LNR/LHV series users must follow these steps:

  1. Go to Live View.
  2. Right-click on it and open the Main Menu.
  3. Click on the Setting icon.
  4. Go to “Network.”
  5. Find “TCP/IP.”
  6. Select DHCP.

After that, it is still necessary to perform a Device Search, as described in Solution #2.

Solution #2: Perform A Device Search

A Device Search is necessary only after you have all the settings correct on the DVR/NVR system.

As the name suggests, it will help you configure the cameras within the system after a major change.

Remember that this applies only to PoE (Power over Ethernet) situations.

  1. Go to Live View.
  2. Right-click on it and open the Main Menu.
  3. Select “Device Search.”
  4. Log in with your credentials (they might be in the user guide).
  5. Check and select the cameras you wish to add to the system.
  6. Click “Add” and wait for the status indicator to turn green.
  7. Click “OK” to save all changes.

If one of the cameras doesn’t show up in the Device Search, you need to disconnect and connect it after 2 minutes.

After restarting, it might take a few minutes to appear in the system.

Note: Live feed can also take up to 2 minutes to start showing up after all cameras are added successfully.

Solution #3: Update Your Recorder’s System And App

Communication among the entire system might also become flimsy if you install the cameras while the system is outdated.

An outdated app might also impact the reliability of notifications and status info regarding your devices.

How To Update The DVR/NVR

Regardless of the model of DVR/NVR you have, the updating process is the same.

These are the steps:

  1. Go to Main Menu.
  2. Click on Settings.
  3. Locate the “System” option.
  4. Click on “Upgrade.”
  5. Locate and click on “Check for Updates.”

If an update is available, it will show up so you can install it. Otherwise, the system will tell you the latest update is installed already.

Update The App

Fortunately, you can check for updates inside the app instead of relying on info from the app store.

Here is how you do it:

  1. Open the Lorex Home app.
  2. Tap on “More” and access the Device Settings.
  3. Click on “Firmware.”

Just like the Recorder system, the app will also tell you whether an update is available or the app is already up to date.

Update The LSHSC

If you own a Lorex Smart Home Security Center and face the “Cannot find network host” issue, it is time to look for a firmware update.

  1. Ensure that the device is connected to the internet.
  2. Access “Device Settings” from the home screen.
  3. Go to “Device Info.”
  4. Click on “Software Version.”
  5. If a new version is available, it will show up right away.
  6. Install it.

Solution #4: Solve A NAT Loopback

Perhaps, in addition to the network host not being found, you can’t access your own Dynamic Domain Name System from inside the house.

Such an issue is known as NAT Loopback or Hairpinning. It prevents you from using an external IP or DDNS inside the network.

Here is how to fix that:

  1. Launch your Client software on any device.
  2. Go to “Device Manager.”
  3. Add the same device you are having an issue with a second time.

The above aims to create two connections. This is why:

  • One connection is for when you are home and using the internal IP address.
  • The other connection is for when you are away using an external IP or DDNS.

Solution #5: Check The Network

checking the network

Do you have Wi-Fi Lorex cameras? In that case, the network becomes a potential culprit in the situation.

That’s because some cameras work with 5GHz frequency while others work with 2.4GHz.

Other issues on the network can also cause the “network host” problem to pop up.

  1. Go to the Lorex system.
  2. Open the Wi-Fi settings.
  3. Check if the cameras are connected to a 2.4GHz or 5GHz network.
  4. Find the user guide or the info page of your camera on the Lorex site.
  5. Switch the connection if necessary.

Moreover, you might need to power cycle your router and the cameras that are connected to it.

Solution #6: Inspect The Ethernet

inspecting the ethernet

If you use connected cameras using a Power over Ethernet switch, you might want to check if the Ethernet cables are fine.

When you receive the “cannot find network host” error, you must check which cameras show as offline or don’t show at all.


  1. Disconnect that camera physically.
  2. Check if there is an issue with the recorder or switch’s port.
  3. If possible, try a working camera on that same port.

By doing the above, you will gain some info. For example, you might assume the issue is the Ethernet cable if other cameras work when connected to the same port.

Thus, change the cable and try again.

Solution #7: Restore The Camera’s Default Settings

Cannot find a network host on Lorex even after all the solutions discussed above? That might call for a reset on your IP camera.

Probably something is wrong with the software on your camera, but since it is Ethernet-connected, you can’t update it.

Instead, the solution is restoring the default settings:

  1. Ensure your camera is connected to the Recorder via Ethernet.
  2. Locate the reset button on the camera (usually on the back).
  3. Hold the button for a while.
  4. Disconnect and connect the Ethernet cable while holding the button.
  5. Hold for at least 15 seconds before releasing.

After releasing the button, the restart should take a few minutes. Once it has restarted, try configuring it again according to the solutions already discussed.

Solution #8: Reset The Recorder Or Smart Home System

Suppose you have tried plenty of the solutions above, but your Recorder recognizes none of the cameras.

In that case, we should assume that the issue is deep within the software.

If so, it is time to reset it:

  1. Right-click anywhere on the display.
  2. Choose the “main menu” option.
  3. Inform your password.
  4. Select the hammer and screwdriver icon.
  5. Select the “Settings” option.
  6. Look for the “Default” option.
  7. Click on the box that stands for “Factory default.”
  8. Click on “Apply” and “OK.”
  9. Wait for the system to restart.

Reset The LSHSC

If the issue is happening on the Lorex Smart Home Security Center and updating its settings hasn’t helped, you will need to perform a reset on it:

  1. Go to the LSHSC’s home screen.
  2. Navigate to “Device Settings.”
  3. Select “Restore to Factory Settings.”
  4. Confirm by tapping “Yes.”

The device might take a while to restart. After that, try communicating with the cameras again. 

Quick Recap

Sometimes, your Lorex cannot find a network host, and that has to do with settings, which you must be very attentive to.

Some configurations prevent the correct communication between the recorder and cameras, but we have laid down a lot of instructions that will help you.
