Troubleshooting Network Issues
When connecting to a DVR using a mobile application or from a computer, communication betwixt the devices is dependent on network connectivity. Networks are typically comprised of two main parts:
- Local Area Network (LAN)
- Instance: 192.168.1.ninety or 10.0.0.2
- Wide Area Network (WAN / Internet)
- Instance: 47.180.64.226
The type of network connection determines how devices can connect with a DVR, besides every bit how to troubleshoot whatever network issues that may occur. For instance, the utilise of an internal LAN accost will just permit connectedness to the DVR if the connecting device is on the aforementioned internal LAN every bit the DVR.
This article will depict common network connection problems and how to troubleshoot the bug, depending on the type of network connection that the issue is occurring on.
Note: It is recommended that you are onsite when troubleshooting network problems.
Note: If yous accept not completed the Network set up procedure, please read the post-obit article most relevant to your DVR model:

- VMAX A1 Series (2.1 MP)
- VMAX A1 Plus Series (five MP)
Common Causes of Network Bug
- Ability interruption
- Changes to the router
- Changes to the Cyberspace Service Provider (Internet access provider)
- Router or Network Hardware Issues
Default Settings
Network setting data for the VMAX standalone units can exist institute inside the Network Menu of the DVR.
The following information is the default Network and System settings of the VMAX A1 Plus:
- Local IP Address: 192.168.i.160
- Subnet Mask: 255.255.255.0
- Gateway: 192.168.1.1
- TCP/IP Port: 9010
- Web Port: fourscore
Note: The VMAX A1 Series and the VMAX 960H Cadre Series combine the TCP/IP Port and Spider web Port into the Network Port (80).
Wide Area Network (WAN) or Net Connection
A common upshot that Users may encounter when trying to connect with their DVR, is being able to connect and monitor camera streams only while onsite, but not while they are away.
If a User is trying to connect with a DVR from an exterior location, the DVR requires an unhindered Internet connection to communicate with the outside device, as well as Port Forwarding permissions through the router.
If you lot are encountering problems connecting over WAN:
- Make certain that the connectedness information that you lot are using is correct. Ostend that the Public IP Address or URL (DDNS) that you are using is correctly entered into your viewing application.
- Confirm that the TCP/IP/Mobile Port, Web Port, User ID, and Password are also correctly entered into your viewing application.
- If yous are onsite and using a Public Address (WAN) in the grade of either a Public IP or a DDNS address, confirm that you are non connected to Wi-Fi (LAN) and are using an external network. An external network can exist the use of the mobile data network (4G/5G) besides.
Port Forwarding Status
To check the Port Forwarding rule(s) status, open a browser on a local computer that shares the aforementioned network as the DVR.
- Visit CanYouSeeMe.org ( https://canyouseeme.org ) or another port checking website of your choice. In the Port to Bank check box, enter the TCP/IP/Mobile Port number (located in the DVR's Network menu), and so click Check Port.
- If the DVR is using a Web Port or Network Port, enter the number (located in the DVR'south Network menu), then click Cheque Port.
This site pulls the Public IP Address of the router and allows you to test port forwarding rules. You will want your port(southward) to show successfully open.
- If the status shows an error or failure during the port cheque, Reboot the DVR.
If the network consequence was acquired past a power pause, ability-cycling the DVR may re-establish network communication with the router. Check the port condition once more after the DVR completes its reboot.
If whatever of the ports show airtight, or you lot are still unable to connect remotely over the WAN, confirm that your DVR is even so communicating over LAN and that there are not typos in the Port Forwarding Rule(southward). If Port Forwarding was not set up on the router, please read the most relevant Network Setup commodity (listed above and at the lesser of this article).
Otherwise, continue with troubleshooting the Local Area Network (LAN) connection.
Local Area Network Connection (LAN)
When encountering external connectivity issues with a DVR, it is a good idea to verify if you take the ability to connect internally as well.
Before the DVR communicates over the Internet, it connects with local devices within the Local Network (LAN). Examples of local devices are computers, phones, tablets, and any other devices within the same network equally the DVR.
While connected over the Local Network, these devices tin can communicate without the presence of an external network (WAN) connection.
To connect with the DVR over LAN:
- Confirm that you are using the DVR'southward Local IP Address (located in the DVR's Network bill of fare).
If you are using a Public Address (WAN) in the form of either a Public IP or a DDNS address, you volition non exist able to connect to the DVR by Wi-Fi (LAN) or with an ethernet (LAN) connectedness. This is because the apply of an external (WAN) accost will non permit communication with internal (LAN) devices.
Testing LAN Connectedness
If you have a computer continued to the same LAN as the DVR, open a web browser and enter the DVR'south IP Address into the address bar. If the DVR has been assigned a Web Port value of anything other than 80, you will also need to specify the Web Port value in the address bar.
Instance:
DVR IP: 192.168.1.90
Web Port: 8245
Example URL for connecting from a browser:
If the address is entered correctly and the DVR is communicating over the LAN, the DVR'southward Web Viewer will display. The User ID and Countersign will be the same login that is used at the DVR also (Default: admin/--- (no password)).
