Port Forwarding Configuration for DVR and IP Camera
We will look at the main factors that you must consider if you want to access your surveillance camera system from the outside.
How to Access any Device Remotely.
To remotely access any device on your network, the system must first understand what you want to do. If you have a NAS Server, a camera, or some other service on your local network, these devices will be identified by an IP address and a port.
When we know the IP address of a service, such as a video surveillance camera, we must also know the port. When we use a web browser or something similar, the port comes after the IP address.
Once we have the IP address of the camera and the port it uses to connect (usually port 80), we need to tell our router that we are going to access that port from outside (IP EXTERNAL:PORT), and the traffic will be redirected to the IP camera's internal IP address.
You can use online applications like canyouseeme.org or portchecker.co to see if your ports are open or whether Internet provider has blocked the ports.
The normal thing to do is to redirect the input port (8586 in our example) to our local network's internal IP address. This is accomplished through the use of our router's port forwarding settings or redirects.
How do I find out what port my IP camera is on?
As we have seen, knowing the port used by our IP camera or the DVR is critical. One disadvantage is the lack of market unification. Ports are typically used differently by each brand.
Most DVR's and IP cameras use standard ports 80 or 8080 to access their viewing or configuration. There are numerous lists where we can find the ports used. Even within the same brand, some models have different configurations than others.
The following are the best practices for determining the port of my IP camera:
Make use of the brand's software.
Apps like FING allow you to search the web (for Android and iOS).
Connect to the router and look over the list of devices that are connected.
Software like Advanced Port Scanner is very useful in this regard.
With any of the three systems, we will undoubtedly find the IP address of our video surveillance camera, as well as the access port, within its configuration. We can certainly change it.
The significance of an ISP
Typically, each internet service provider (ISP acronym in English for Internet Service Provider) has its own set of rules, benefits, and limitations. Certain ISPs disable ports because they are blocked for internal use or because they see a lot of traffic on those ports.
Other businesses employ CGNAT technology, which prevents port forwarding and router access.
How to view multiple IP cameras connected to the same port
If you do not have a video surveillance or IP camera management system and have a number of cameras, you may want to access them individually. If all of the cameras are of the same brand, they will almost certainly share the access configuration and thus have the same port.
If you want to access them from the outside, you won't be able to because if you enter through port 80 and have the port redirected to an IP, you won't be able to redirect it to another or a different IP, Since all the cameras share the same port.
This can be solved in two ways, one of which is to assign a different port to each camera.
The alternative solution is simpler. To forward the ports, you must enter the external and internal ports in the router configuration. You can redirect the different internal IPs by configuring an external port for each of the cameras.
Internally, all IP cameras will use the same port, but externally, you can use 81,82,83, and so on to access all of your IP cameras separately.
Set up a DDNS server.
An IP address is typically composed of four groups of two or three numbers (for example, 192.168.16.135) and can be difficult to remember. Furthermore, ISPs frequently change the external IP address of our connection.
Always use DDNS to help you remember your IP address. The Dynamic Domain Name System (DDNS) allows us to create a name type "name.service.com" and have it always correspond to our external IP address.
In short, if you want to see surveillance cameras externally meaning outside LAN (Local Area Network), you must know the port they use, their internal address, and their external IP address. Once you've determined this, you'll need to configure your router and use a DDNS to access your IP cameras or video surveillance management system.
In this video we will be demonstrating on how to do the port forward settings to a cctv dvr. We will be using a ZTE F660 router and AVTECH DVR for this purpose. AVTECH DVR's have a free DDNS and hostname, so we will be configuring the settings to view the DVR online.
