Security DVR Troubleshooting Guide

Follow the steps below to resolve general DVR issues. See the Manual for your DVR to troubleshoot issues that are specific to your DVR series or model, such as motion recording.

 

Cannot Connect to DVR on Local Area Network (LAN)

  • IP address not entered correctly. If connecting using a web browser, enter http://, the IP address, colon, and then the HTTP or web port of your DVR (e.g. http://192.168.5.12:80). If connecting using client software enter the IP address only (e.g. 192.168.5.12). Check your DVR manual for information on how to find the IP address, web port, or HTTP port.
  • The DVR is not connected to router. Connect an Ethernet cable from the DVR LAN or Ethernet port to your router, and turn your DVR on and off.
  • DVR and computer are not on same network. Ensure your DVR and computer are connected to the same router. If your computer is using a WiFi network, try connecting it to the router using an Ethernet cable.

 

Cannot Connect to DVR Over the Internet

  • Ports have not been forwarded on the router. Port forward all ports used by your DVR on your router to your DVR's IP address. See the Easy Connect Wizard - Auto Port Forwarding your Router or Port Forward a Router guides for more information. See your DVR manual to determine the ports required by your system.
  • HTTP, web, or other ports blocked by Internet Service Provider (ISP). Port 80 is sometimes blocked by ISP's. Revise your web port to any number above 1025 and port forward the newly selected port. When connecting using a web browser, you need to include a colon and the HTTP or web port after your DDNS address (e.g. http://tomsmith.lorexddns.net:80). If you still can't connect, you may need to contact your ISP for assistance with port forwarding. You can test your port forward configuration using third-party port forward testers at http://www.checkmyports.net/, http://www.yougetsignal.com/, or http://canyouseeme.org/.
  • Your local network has more than one router installed. For example, you may have a modem that also acts as a router connected to a wireless router. Click here for information on how to port forward with multiple routers.
  • DDNS account not created. A DDNS account allows you to create a web address that points to your local network, so you can view video from your system from anywhere in the world. Click here to sign up for Lorex's free DDNS service.
  • DDNS has not been enabled on DVR. Your DVR must be configured to communicate with the DDNS service. Check your DVR manual for instructions on how to enable DDNS on your system.
  • DDNS address not entered correctly. If using a web browser, enter http://, the URL request from the confirmation email, followed by .lorexddns.net, colon, and the HTTP port (for example, http://tomsmith.lorexddns.net:80). If using client software, enter the URL request from the confirmation email followed by .lorexddns.net (e.g. tomsmith.lorexddns.net).

Cannot Connect to DVR using a Mobile Device

  • Internet setup has not been completed. See the steps above to troubleshoot Internet setup.
  • DVR's local IP address used from outside internal network. A DVR's local IP address can only be used to access devices on the same network. Use the DDNS address to connect to the DVR over the Internet using a mobile application.
  • The router is blocking DDNS connection from internal network. Some routers will block this type of connection. Turn off your WiFi connection and attempt to connect to the DVR's DDNS address using your 3G or mobile network. If you need to use WiFi, use the DVR's local IP address to connect from inside the same local network as the DVR.

 

Internet Connection to DVR is no Longer Working

  • External (public) IP address of your network has changed. On most residential Internet service plans, your external IP address will occassionally change. Register for Lorex's free DDNS service to ensure 24/7 connectivity to your system. A DDNS account allows you to create a web address that points to your local network and automatically updates when your external IP address changes. Click here to sign up for Lorex's free DDNS service.
  • Internal IP address of DVR has changed. After a power outage or if your router restarts, your router may assign a different IP address to your DVR or other devices. If your DVR's internal IP address changes, you will need to re-configure port forwarding. It is recommended to assign a fixed IP address to your DVR, so the IP address will be permanently set. See Assigning a Fixed IP Address to Your DVR for more information.
  • If you have purchased a new router, you will need to re-configure port forwarding on the new router. See the Easy Connect Wizard - Auto Port Forwarding your Router or Port Forward a Router guides for more information.

 

DVR is not Receiving power or not Powering up

  • Verify that the power adapter cable is plugged into the DVR and a power outlet. If the DVR has a power switch, check that the switch is set to the ON position. Some power adapters have two sections that may have been disconnected in the middle.
  • Make sure you are using the correct power adapter for the DVR. If the power adapter does not provide sufficient power for the DVR, it may prevent the system from powering up or detecting the hard drive. You can check the output of the power adapter on the power adapter label. DVR's and monitors generally have high power requirements (2A or greater). Cameras generally have lower power requirements (less than 2A). You can check the Product Specifications on the Downloads tab for your model for the specific power requirements.

    Power adapter label
  • If the DVR is connected to the outlet via a power bar or surge protector, try connecting the DVR directly to the outlet.
  • Confirm there is power at the outlet. Connect the power cable to another outlet. Connect another device such as a lamp or phone charger into the outlet. Contact an electrician if there is an issue with a power outlet.
  • If the power adapter has a status LED, make sure it is on when the power adapter is connected to the outlet. If the LED does not turn on, the power adapter is not working. Contact Lorex Technical Support for assistance.
