[ DVR ] [DVR-Installation] I connected the camera but the signal does not work.

First of all, when connecting the main equipment, confirm that the cable’s +,-cord is accurately  

connected. Then go to Setting → Camera → PTZ and set the ID, protocol, and transmission  


[ DVR ] [DVR-Login] Upon clicking on the menu icon button, the message

In order to execute a function you must log in. Use the keyboard on the screen to enter your password.  

The initial password is set as "000000".

[ DVR ] [DVR-Login] Upon clicking on the set-up button, the message

Depending on the user, there are different user rights.

- ADMINISTRATOR : Able to carry out all the functions.

- POWER USER : Able to carry out all the functions excluding the configuration.

- NORMAL USER : Every function is restricted except: screen partition and real-time screen surveillance. 

[ DVR ] [DVR-Login] Upon logging in, a portion of the channel screen does not appear and only the LG logo appears.

If the “covert” status is “ON” for a certain channel, “power users” or “normal users” cannot access the video.  

Please change the “covert” status to “OFF” to see the videos for the channels you cannot see at the moment.  

Administrator log-in → Settings → Camera → Covert → OFF.  

[ DVR ] [DVR-Display] The screen suddenly displays only one screen.

Confirm that the Menu control stick → MAIN → Screen partition space is not set as one. You can also set to partition screen  

simply by double-clicking your mouse.  

[ DVR ] [DVR-Display] While using the VGA monitor, I switched to the TV monitor and the screen does not show anymore.

If you used the VGA monitor as the main monitor and then started using the MAIN OUT monitor as the main monitor,  

press the SPOT button on the front of the equipment until a you hear a signal sound. The DVR will reboot and the TV(Composite)  

will be set as the main monitor.  

If you wish to execute the other way around and switch from the TV(Composite) to the VGA, press the MAIN button until  

you hear a signal sound.  

[ DVR ] [DVR-Record] How can I choose the appropriate resolution for each environment?

Please refer to the "Recording Time Table" located at the very last page of the manual for the DVR's recording time.  

This table, assuming moderate activity in the image, offers recording time information based on different resolutions,  

image qualities, and fps when the 250GB hard disk is in use. However, the information in the table can vary depending  

on the activity level and complexity in the image. 

Should there be a need to record for a long period of time, set the resolution, image quality, and fps as low. For sites where

activity is rare, it is efficient to set the DVR so that it records only when there is motion. That way, you can use the hard disk for 

 a longer period of time. 

If image quality is more important than the recording time, you can set the resolution, image quality, and fps as high.

[ DVR ] [DVR-Record] I set the recording configuration as

Please check the following items.
1. HDD recognition : Check the HDD information on the information window.
2. Recording configuration : Double check the recording configuration for each channel and day.
3. Event partition : If the event partition is at 100%, there is no HDD space for continuous recording.
4. Overwriting : If the overwriting setting is off or it is set as an event partition, continuous recording will not work

after the event partition capacity is full. 

[ DVR ] [DVR-Record] Motion recording does not work.

1. Recording schedule (setup → schedule)
2. Motion sensitivity: no motion event will be generated if set as "None".
3. Motion region : no motion event will be generated without a set motion region.
4. Event partition : if the value is "0%", no motion event will be generated.
5. Overwriting : if the event partition is full while the "overwriting" feature is set off, motion recording will not work.

[ DVR ] [DVR-Record] I set the DVR as motion recording, but the blue M icon does not appear; instead, a green icon appears.

Did you press the REC button on the remote control after adjusting the recordings settings? If you press the REC button  

on the remote control, recording will be executed immediately and thus a continuous recording will take place.  

In order to stop the immediate recording function, press the REC button one more time.  

[ DVR ] [DVR-Play] I wish to watch the video recorded yesterday. How do I play it?

Go to Search(Magnifier icon) → Date search → Time search and press the OK button.

[ DVR ] [DVR-Play] When playing the video, is assigned playing possible?

When playing, use the rewind, fast-forward buttons on the bottom right to play and play backwards.  

You can play backwards with a speed 2times, 4times, 8times, or 16times faster.  

You can play normally with a speed 2times, 4times, 8times, 16times, and 32times faster. 

[ DVR ] [DVR-Play] I am trying to watch the video recorded yesterday but the message

When you go to Search → Date/Time search → Update, a bar according to the recording settings will appear on the right table.  

After selecting the channel(vertical 1~8/ 1~16) and the time (horizontal 02~22), press the play button on the bottom left. 

[ DVR ] [DVR-Play] While watching the recorded video, the video keeps snapping and there are parts missing in the middle.

Are you using the motion recording method? Please check the recording schedule (setup → schedule).  

When using the motion recording method, it will only record when there is motion; thus when there is no motion,  

it will seem as if the video snaps and there are missing parts. 

[ DVR ] [DVR-Backup] I got a backup but it won't play on the PC.

The DVR Set-up - System - Backup only plays on the DVR; when playing on the PC, you must receive the Export backup. 
Menu Control Bar →
 Export → Equipment, channel, date/time → Copy. After backup, you can play by using the Export view  

that forms with the recorded data. 

[ DVR ] [DVR-Backup] I wish to

It could vary depending on the size of the recorded data within the HDD, but it is not possible to "Export" the data  

recorded over a long time interval at once. It is secure to divide the entire time by 2 hours intervals before exporting the data. 

[ DVR ] [DVR-Backup] When executing the backup, can I backup by using a program that can be played by AVI files or other general players?

When executing backup by using Export as a Client, it is possible to save using AVI files. However, if you save as AVI files,  

you must install the Client program on the PC in order to install the codec needed to execute other players. 

[ DVR ] [DVR-Backup] I am trying to backup on my USB memory stick, but the message

Please format using the Delete Media item on the backup screen settings. Before doing so, secure important data  

in your USB somewhere else.

- The standard ports for LE1004 are Web 80, Play 9091, and Live 9092

[ DVR ] [DVR-Network Set-up] I wish to gain access from remote areas through the internet. How do I set-up? (When using a fluid IP)

Set the IP assigned by the router as fixed on the DVR, then go to the router settings to port forward the TCP/IP port  

and Web port according to the DVR IP.
Use the Network IP address shown on DVR menu control bar →
 INFO(System info) to port forward the standard ports  

in the router settings - 9001 and 80.
* For the LE1004, use the network IP address to port forward the standard ports in the router settings - 80, 9091, 9092.

After port forwarding, use the Wan IP on the router to access the web viewer on the internet.  

Please enter http:// on the internet address space and the confirmed IP address.  

You can use it as the Fixed IP if you go to DVR Setup → Network → TCP/IP and enter the IP address,  

subnet mask, and gateway then set the DHCP as OFF.
The standard value of the Web port used for the DVR is 80.
If an error occurs while using port 80, change to another number and port forward that new number.

[ DVR ] [DVR-Network Set-up] I am using a fluid IP and router. I wish to access the DVR as a Client by connecting to the network.

When using a router, you must first set the assigned IP as fixed on the DVR.  

Then you should go to the router settings and port forward the TCP/IP port and Web port for the DVR IP. 

▶ Setup - Network - TCP/IP
▶ IP address, subnet mask, gateway : manual
(Example),, router's interior IP)
▶TCP/IP port : manual, (ex)9002

** When connecting more than two DVRs to one router, you must use different IP addresses and TCP/IP ports.

▶Port forwarding
   Set up the router so that the IP for each DVR can use the assigned port, refer to the router manual.

[ DVR ] [DVR-Network Set-up] The IP is set as but the web doesn't connect from the interior. is a IP that is set even if the network isn't connected.

If there are no problems with the router or the connection cable, set Setup →
 Network → TCP/IP → DHCP : ON,  

and reboot the DVR and the router equipment.  

If the same phenomenon occurs even after the reboot, set Setup → System → Setup → Setup Initialization.  

However, the standard setup value becomes initialized upon initialization. 

[ DVR ] [DVR-DDNS] I wish to use the DDNS.

In order to use the DDNS, you must first set the network.
Set the network appropriate to the fixed IP, fluid IP, or router environment.


When the network setup is completed, go to Setup → Network → DDNS menu and set the DDNS service item as ON,  

then enter any name for the host name. Click the update button and the hostname for the DDNS server will be entered.  

A 'success' message will appear.
In case of failure, follow the instructions on the message.
After the hostname is entered, you can enter the hostname on the internet browser address space in place of the IP address. 

[ DVR ] [DVR-DDNS] The update does not work.

Is the DDNS service set as OFF?
1. Set the DDNS service as ON, then enter the hostname.
2. Press the update button.
3. If the update is successfully applied to the DDNS server, the address ******.
lgddns.com will be formed in the host space.
4. If the update is not successfully applied to the DDNS server, the message "DDNS server not found.

    Please check the network setup" will appear.

In this case, if the modem and router has no defect, double check the network connection cord. If the router port has  

a defect or the product experienced a temporary defect, reconnect the LAN cable and reboot.  

[ DVR ] [DVR-Web Viewer] I cannot connect to the web using the DDNS host or IP address.

Please check the following items.

1. Network connection
   1) Cable connection status:

       Check that the green LED is ON and the yellow LED is blinking on the LAN port.
   2) IP, Subnet mask, Gateway status
      - Use Fixed IP: check if the value is accurate

   3) Go to Setup - System - NTP menu and set NTP as ON.

       Carry on TEST and confirm Network's connection.
   4) If using router, check that the port forwarding for the web port is complete.

2. DDNS Setup
   1) Confirm that the DDNS usage is ON
   2) Update DDNS and renew to current status

3. Confirm address on the web browser
   1) Did you enter http:// before the address?
   2) Did the port change?
       If the Web Port did change, place (:)+alteration port at the end of the address.

       If the TCP/IP port changed, you must enter the changed port in the log-in page port LAN.

[ DVR ] [DVR-Web Viewer] How do I play?

The play function is not supported on the web viewer. If you wish to use the play function, install the Client program  

and enter as Client. Web viewer only supports live functions. 

[ DVR ] [DVR-Web Viewer] I logged in successfully but I cannot watch the video.

Did you log in using an ID other than the administrators?

- Only the recorded videos of IP cameras, that are registered with Smart Station, can be loaded and viewed.  

Loading a remote video and monitoring it on Smart Players is possible if user installs NAS and connects it using network drive  

- To watch the "NAS-stored" recorded video of IP Camera (registered with Smart Station) using another Smart Station,  

user must register the IP Camera onto the new Smart Station and export file as AVI 


Note) If Smart Station is installed in two places (#1: Local N/W within IP router, #2 N/W outside of IP router),  

video can be recorded using NAS in one place, and Smart Station in another place.
However, 1 IP Camera cannot be recorded to both NAS and Local HDD of Smart Station using only 1 Smart Station.
(Will be recognized as a single Local HDD in NAS, Local HDD, and Smart Station) 

[ IP Camera ] Is simultaneous recording possible between NAS that is installed with IP camera (same subnet) and Smart Station?

Yes, simultaneous recording is possible if you install Smart Station within the local n/w of IP router and configure  

it so that it can record to NAS and install Smart Station outside of the router, so that it can record separately (local HDD)

For storage:      

    Within router: NAS      

    Outside of router: Local HDD 

[ IP Camera ] Recording does not work

1. Check Video Stream was assigned after setting up Recording Schedule
