The following guide describes the uses of common ports that are used on Lorex security DVRs. The availablity of ports, their appearance, and their functions varies between DVR systems. Check the product Instruction Manual or Specifications Sheet for details on the ports used on each system.
Used to connect the male end of a power adapter to provide power to the DVR. Only use the included power adapter with your DVR. To connect a BNC cable, push the cable in and twist clockwise. See the camera Cables and Connections guide for more details. To connect cameras to a DVR using an Octopus cable, connect the single end of the cable into the DVR and tighten the screws to secure the connection.
Connect the cameras to the individual ends of the Octopus cables. Labels are used to identify the channel each connector on the Octopus cable corresponds with. DIN cables are proprietary, which means they are specific to the manufacturer and you cannot mix DIN cameras from different manufacturers. Lorex DIN cables use either a 4-pin or 6-pin layout. DIN cables are capable of connecting video, 2-way audio to and from the cameraand power to the camera between the camera and DVR. When connecting DIN cameras to the DVR, make sure to align the pins correctly, as inserting the cable incorrectly may damage the pins.How to setup Port Forwarding for Hikvision NVR
Check the Instruction Manual for your Lorex system. A Spot Out monitor automatically shows camera channels in sequence, and cannot be used as a main display. Depending on the DVR model, you may be able to select which channels will be shown and the amount of time channels are shown before switching.
USB, or Universal Serial Bus, is a common computer port used to transmit data to and from external devices. USB ports are often indicated using this symbol:. To connect a DVR to a LAN or the Internet, connect an Ethernet cable from the Network port to an available network port on your router and follow the included instructions to configure the DVR and router for remote access.
You must use an Ethernet cable to connect your DVR to the network. Used to connect the RCA audio cables from audio-enabled cameras or self-powered microphones to allow audio recording on the DVR.
The maximum number of audio channels supported varies between DVR models. Used to connect the DVR to multiple audio-enabled cameras or self-powered microphones through the same port using an Audio Harness Cable, which is usually provided with the system.
To connect audio-enabled cameras or self-powered microphones using an Audio Harness cable, connect the single end to the Audio Harness Input port and tighten the screws to secure the connection.
Then connect the audio cables from the cameras or microphones to the individual ends of the Audio Harness cable. Like the BNC Octopus cable, the labels at the end of the connectors are used to identify audio channels. Audio-enabled cameras or self-powered microphones are required to play sound from the DVR.

It only takes a minute to sign up. I have seen advice saying you should use different port numbers for private applications e. It doesn't provide any serious defense against a targetted attack.
If your server is being targetted then, as you say, they will port scan you and find out where your doors are. However, moving SSH off the default port of 22 will deter some of the non-targetted and amateur script kiddie type attacks. These are relatively unsophisticated users who are using scripts to port scan large blocks of IP addresses at a time specifically to see if port 22 is open and when they find one, they will launch some sort of attack on it brute force, dictionary attack, etc.
If your machine is in that block of IPs being scanned and it is not running SSH on port 22 then it will not respond and therefore will not show up in the list of machines for this script kiddie to attack. Ergo, there is some low-level security provided but only for this type of opportunistic attack. By way of example, if you have the time - log dive on your server assuming SSH is on port 22 and pull out all the unique failed SSH attempts that you can.
Then move SSH off that port, wait some time, and go log diving again. You will undoubtedly find less attacks. It cut the opportunistic attacks by orders of magnitude. If you see failed attempts with sshd running on port you can safely assume that the person is targeting you and you have the option of taking the appropriate action if you so desire.
Such as contacting the authorities, investigating who this person may be by cross referencing with the IPs of your registered users or whateveretc. If you use the default port then it will be impossible to know if someone is attacking you or it's just random idiots doing random scans.
No, it doesn't. Not really. The term for this is Security by Obscurity and it's not a reliable practice.
You are correct in both of your points. Security by Obscurity at best will deter the casual attempts that just go around looking for default ports knowing that at some point they will find someone who left the front door open.
However, if there is ever any serious threat that you face changing the deault port will at most slow the initial attack down, but only ever so marginally because of what you've already pointed out. Do yourself a favor and leave your ports configured properly, but take the proper precautions of locking them down with a proper firewall, authorizations, ACL's, etc.
It's a slight level of obscurity, but not a significant speed-bump on the road to hackage. It's a harder config to support long-term since everything that talks to that particular service has to be told about the different port. Once upon a time it was a good idea in order to avoid network worms, since those tended to scan just one port. However, the time of the rapidly multiplying worm is now past. Imagine the following simplified scenario. A cracker scans hosts. Ninety-nine of these hosts have services available on these standard ports:.
But then there is one host which stands out from the crowd, because they the system owner tried to obfuscate their services. If you were a cracker, would you choose to take a look at one of the 99 hosts running standard services on standard ports, or this one host which is using port obfuscation?
On it's ownchanging to a different port might gain you a couple of seconds while it's searched for, hence gaining you nothing in real terms. However, if you combine the use of non-standard ports together with anti-portscan measures it can give a really worthwhile increase in security.Similarly many of the official assignments refer to protocols that were never or are no longer in common use. This article lists port numbers and their associated protocols that have experienced significant uptake.
On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well-known ports. They are assigned by IANA for specific service upon application by a requesting entity. From Wikipedia, the free encyclopedia.

Also please obtain all passwords to each device if necessary to ensure flawless setup as we go from procedure to procedure. Then hit the enter key and you should have a window like the following:. The one you will see my network in is a You should have now the following window:.
As you see in the picture above my gateway This is the unique IP belonging only to my device my computer. Every device that is attached to my network is issued its own unique IP address. On my network I suggest anyhow, to always change the IP address of any our devices to a known open IP on your network.
You can see if an IP is open or not by pinging your network. It will look like so:. Above you can see this IP address is assigned to another device due to the com packet replies Above you can see the IP address is not in use.
Now that we have established an open IP to assign to the device lets change it. If you right click on the mouse of the DVR, chose the following:. Configure your network to the chosen IP in the IP address field. Make sure to change the Default Gateway in the respected field as well if your network requires. I now will save my configuration. If the DVR prompts you that it wants to reboot, this is fine and a necessary function.
Just hit okay. Please refer to the picture below:. I will now access my router by putting in the password. Once Inside I can now create port forwarding rules for my device. The current router I am using is a Linksys AC.In computer networkingport numbers are part of the addressing information used to identify the senders and receivers of messages.
Port numbers allow different applications on the same computer to share network resources simultaneously. Home network routers and computer software work with these ports and sometimes support configuring port number settings. Networking ports are software-based and unrelated to physical ports that network devices have for plugging in cables.
Port numbers relate to network addressing. These port numbers work like telephone extensions. Just as a business telephone switchboard can use the main phone number and assign each employee an extension number, a computer can have a main address and a set of port numbers to handle incoming and outgoing connections.
In the same way that one phone number can be used for all the employees within that building, one IP address can be used to communicate with various applications behind one router. The IP address identifies the destination computer and the port number identifies the specific destination application. This is true whether it's a mail application, file transfer program, or web browser. When you request a website from a web browser, the browser communicates over port 80 for HTTP. Then, the data is sent back over the same port and displays in the program that supports that port the web browser.
Port numbers are automatically processed by the network hardware and software. Casual users of a network do not see these port numbers and don't need to take any action involving their operation. Individuals can, however, encounter network port numbers in certain situations. Network administrators may need to set up port forwarding to allow the port numbers of specific applications to pass through a firewall.
On home networks, a broadband router supports port forwarding on its configuration screens. The most common application of home port forwarding is for online games that use non-standard ports that the router's built-in firewall blocks.
Network programmers sometimes need to specify port numbers in their code, such as in socket programming. This is usually seen in software development environments more than in mainstream consumer usage. Network security enthusiasts also frequently discuss the port number used as a key aspect of attack vulnerabilities and protections. Ports can be classified as either open or closed. Open ports have an associated application that listens for new connection requests and closed ports do not.Thanks for your subscription!
What is port forwarding of IP security cameras? How to set up IP security camera port forwarding for remote viewing? How to fix IP camera port forwarding not working? Which IP address should you use for IP camera port forwarding? Well, don't be freaked out by the above questions. We can help you deal with these puzzles, and, more than that, offer you a shortcut to avoid port forwarding to your IP camera and get remote viewing!
IP camera port forwarding is a function of network routers that enables you to configure specific communication ports to be routed to your IP security cameras and systems on the Internet. Here is an analogy to explain the IP camera port forwarding — when you live in a hotel, your friend can get your room number by providing your name to the hotel manager. That's how "port forwarding" works. In other words, when you enable port forwarding for IP cameras, you are turning on remote Internet access for the IP surveillance cameras.
Editor's Note: Not all IP cameras allow for or need port forwarding. For example, the battery powered cameras can't be accessed via the web browser where the camera will be always on, and therefore, drain the battery life quickly. After you set up port forwarding for your IP surveillance cameras, the router will forward incoming Internet requests on the port that your IP camera uses, so that you can access the camera remotely over the Internet. The below chart simply illustrates the process on how to access your IP cameras via the local and external network.
Editor's Note: There is NO need for IP camera port forwarding if you want to access the camera in the LAN local area network — that's when your devices share the same router network with the cameras.
All you need is a correct IP camera address and type it in the web browser address bar, that's it. However, if you want to view live streaming of your IP cameras in external Internet, you need to configure IP camera port forwarding. In fact, all you need to do is to find out these two things and set up the IP camera port forwarding rules so that you devices can find the camera correctly.
Each IP camera has its own IP address. Different IP camera brands vary in the ways of checking the IP addresses. Here we take a Reolink IP camera as an example. We assume that the IP address of this IP camera is Pro Tips: You can set the IP address of the Reolink camera to be static instead of DHCP so that you wouldn't have to change the portforwarding every time my router reboots. How do I find my IP camera port? What port does a security camera use?
Obviously, the port number is crucial in IP camera port forwarding, and it can be easily found with the security camera software. After that, you can see the 2 ports of this camera. Note: IP camera port forwarding numbers can be changed according to your situation. Select both if possible, otherwise select TCP. Note: Different routers have different pages to set up port forwarding. You can read the user manual of your router for more details. Now you are actually done with the IP camera port forwarding, but there are still two simple steps to go to access the camera live via security camera port forwarding:.
Solution 2: Change the port number into another value below other than port Sometimes you may experience problems with port Find that the IP camera port forwarding is a little bit tech demanding and get lost somewhere in the guide?
List of TCP and UDP port numbers
June 29, by Matthew Rossi. Port forwarding is essential to making your security DVR or NVR accessible from online using either your computer or mobile device.
It is a configuration setting in your router that must be set properly in order to view your security camera system from the internet. We commonly hear from customers the complaint that they are able to see their video recorder from a computer on the same router, but not from their phone or from a computer at another location.
Here's a brief explanation of why this happens:. Every router these days has a built-in firewall which blocks traffic from the internet from accessing the internal local network behind the router. The firewall will not block local traffic on the network from accessing the DVR, so you will still be able to view your camera system as long as you are at home and on the same network as the DVR.
Unless you enable port forwarding in your router you will not be able to view your cameras from elsewhere or from your phone using its cellular data connection. Depending on the manufacturer of your surveillance video recorder, it will use specific ports for web login, data communication, and video streaming to serve up the camera feed.
All of our recorders have the following default ports configured when they ship:. It is only necessary if you want to be able to view the login webpage. Port - This is a TCP type video streaming port that is necessary for viewing video using any method, i. RTSP is an advanced feature that allows integration of camera streams coming to the DVR to be connected to another device, like a access control system or for embedding video on a website.
For our video recorders, at a minimum you must enable port forwarding rules for ports 80 and for remote viewing to work smoothly. One port rule for port 80and one rule for port If you have a residential internet service plan, chances are port 80 is being blocked by your ISP. In such an event, you will make a rule for port or something similar instead of port As long as you configure everything correctly in both the DVR and your router, everything should work fine.
The first thing you should do when configuring port forwarding is determine all of your network information. This means IP addresses, login credentials, port numbers needed for your DVR, all of which is essential information.
We will go over what these pieces of information are, and the easiest ways to find them. This is your IP address on the Internet. All of the computers on your local network are behind this IP address.
