If your CCTV DVR or NVR don’t have a built-in WiFi support, then you have to run internet cable (CAT 5 or CAT 6 Ethernet cable) to connect your DVR or NVR to the internet via the router.
- Connect one end of the Ethernet cable to the Ethernet input on the back of the DVR.
- Connect the other end of the Ethernet cable into a device providing an active internet connection, such as a router or modem.
- Test your internet connection to confirm that it is active by going to the Network > Network screen.
1) Right click mouse—go to Main Menu > Setup > Network.
2) On the Network tab, ensure the “Obtain an IP Address Automatically” option is enabled, and that there is no information in the PPPoE fields.
3) Once you’ve ensured there is no information in the PPPoE field and that the “Obtain and IP Address Automatically” option is selected, select the “Test” option.
If “OK” is displayed, the local area network is connected successfully.
If the DVR is not able to connect to the internet, you will get a message that states “Cannot Connect to Network”.
In order for other devices to connect to the DVR through the router, the DHCP setting must be enabled from the router’s settings page.
If you still cannot connect to the network, please ensure that you don’t have a firewall active on your network that may be limiting the connection.
You may need to open ports 80, 5000, and 5001 on your router, if they’re currently being blocked by te firewall. This typically only happens on commercial internet accounts, as they deal with sensitive transactions, but occasionally a firewall on a residential line will also block these ports.
If you’re unsure how to open ports on your router, you will need to speak with the router manufacturer.
1) What’s DHCP?
DHCP is a type of internet networking approach. It stands for Dynamic Host Configuration Protocol. It means that a router assigns IP addresses to each of the devices on the network, allowing them to communicate with other devices in or outside the network.
In context of our systems, the setting related to DHCP is called DHCP server status. This setting enables your router to obtain the static IP address on the DVR and broadcast that IP to the app so it can locate your DVR. This setting needs to be enabled on a router for the apps to be able to connect to the DVR systems.
2) For example: How to set up a linksys E5350 Router?
Once you’ve logged into the router settings, you’ll want to select “configuration” at the top, and then “Connection > Local Network” in the menu on the left. You should see this page:
You’ll want to ensure the checkbox beside “DHCP server” is checked off, and set the start IP address to 100 as shown in the image. Leaving the other settings here as they default should be fine. Once this is done, select “save.” Before proceeding with the next steps, try using the app while not connected to local WiFi. If you can see the live feeds, you don’t need to complete the steps below.
If you can’t, you’ll need to open the ports in the firewall. On the left menu, select “Security”, and then “Single Port forwarding” as shown in this image:
Select the button on this page for “Add a new Single Port Forwarding”, and this window should appear:
The number you want to enter in the “To IP Address” field is the last three digits of the DVR’s static IP, which you can find on the Network page of the DVR. (Main Menu > Setup > Network)
Application and protocol can be left as they are, and you’ll want to check off the “enabled” box. You’ll need to do this 3 times, using the following information:
Application Name: DVR HTTP
External Port: 80
Internal Port: 80
Application Name: DVR Mobile
External Port: 5000
Internal Port: 5000
Application Name: DVR E-mail
External Port: 5001
Internal Port: 5001
After filling the box with the necessary info for each port, select “apply”, and then hit the add button again to reopen the window. Once all 3 ports are opened, try testing the app again.
Note: different Routers may have different setting interfaces.
