Integrating Gaming PC with CCTV

Let’s start with the basics. We will use an offline setup for gamers to emphasize the concept of a closed-circuit system. In addition, we will mention methods gamers can use to broadcast their camera feed to the internet. It will make it accessible from anywhere in the world. To start the integration process, you will need a set of items. Let’s move step-by-step:

Step 1: Choose the Right CCTV Cameras

CCTV cameras come in various shapes, sizes, and technical capabilities. We typically recommend an IP CCTV camera for gamers in a home configuration. It will provide a crisp video with details ideal for a small-scale setup. There are wireless versions of IP CCTV cameras, but they are prone to interference, which can cause stuttering video or audio. In a surveillance setup, having a wired connection alongside an on-camera SD card recording is the best option.

Connecting an IP CCTV camera with the internet and offline setup is easy. They can provide up to 4K resolution depending on the requirement. Furthermore, users can opt for a camera with a microphone to receive live audio. They only need a RJ45 ethernet connection for data and a power source. However, you will not need two cables running throughout the house for the camera. A single RJ45 cable will suffice. We will explain how to achieve that in the next step.

Step 2: Collecting Necessary CCTV Surveillance Items

After you decide which camera is best for your setup, we can move on to the other items. Here is a list of things for a home surveillance CCTV setup:

·        Cameras: The number of cameras will depend on the number of places you want to perform surveillance. It will serve as a basis for the items next in line.

·        PoE Switch: After deciding the number of cameras, you need a PoE (Power over Ethernet) switch. It will serve as the basis for providing power and transmitting your video to the gaming PC. Usually, people set it up near the computer, and its ports should equal the number of cameras plus one port for computer/router connection.

·        PoE Injector and Splitter: A typical IP CCTV camera requires coaxial power and network cable. A PoE injector and splitter will convert a simple ethernet cable to a coaxial power cable and data transmitting connection. Just ensure that they are IEEE 802.3at/aft compatible.

·        Ethernet Cable: The whole system communicates using the ethernet cable. Calculate the distance between the camera and the PoE switch after routing. There are various categories of ethernet cable available. Their price depends on the quality. We recommend using a Cat5e for its price/performance ratio. Anything above the Cat5e grade is also compatible.

**Note: A typical setup will have a line running underneath the carpet alongside the edges of the wall. Make sure to take proper measurements.

·        Router: You will need a router to connect the complete setup to the internet and ensure your PC remains connected. If you are an online gamer, then you own one. We will explain how to connect all the pieces and make them start working.

Step 3: Camera Placement

Strategically placing your  camera is essential. Ensure it is not easily accessible, and you can route the wire hidden away from eyesight. Following are some of the areas where you can place your camera for surveillance:

·        Front Door Entrance

·        Back Door Entrance

·        Vulnerable Windows

·        Garage

·        Drive Way

·        Hallway

·        Common Rooms

The areas might not relate to your setup, but be sure to cover maximum entrances. Observe where you can mount the camera for complete and precise coverage.

Step 4: Complete the CCTV Setup

Let’s start connecting all the puzzles. Before we mount the camera in their respective location, check connections and equipment healthiness by performing a test. Complete the following process to complete your CCTC setup.

1.   Connect your PoE switch to the power outlet and ensure the lights are on.

2.   Now connect the ethernet cable in one of the ports of the PoE switch and connect the other end to a PoE injector and splitter.

3.   Now take a camera and connect its wires with the PoE injector and splitter. Your camera will now have power.

4.   Take a new ethernet cable, insert it into one of the ports on the PoE switch, and connect the other end with the computer router. Make sure you plug in your gaming PC to the same router.

5.   Download and install the  software from the camera manufacturer’s website. Follow the instruction to access your camera live feed.

6.   You have successfully tested your equipment if you can see the live feed.

7.   As the last step, install your CCTV cameras at their designated location, route the cable, and complete the setup.

Step 5: Start Monitoring CCTV with Gaming PC

Now that you have connected all your equipment let’s obtain the live video feed from your cameras and place an overlay on your favorite game. You will need a decent graphics card and Windows or MacOS computer.

1.   We will be using the VLC media player. Download and install the latest version. It is free to use.

2.   You will be accessing the camera through its IP address. It is usually written and provided by the manufacturer. Check the website or instruction manual.

3.   Start VLC media player.

4.   Navigate to Media > Open Network Stream

5.   Now type the address to your camera with the following settings

rtsp://admin:a1B2c4@192.168.1.5

·        Note that in the address given above, the camera username is (admin), the password is (a1B2c4), and the IP address is (192.168.1.5). Everything else will remain the same.

·        After you enter, you will start streaming your IP CCTV camera.

·        Now, right-click on the live stream, navigate to view, and always click on top.

·        Right-click on the live stream and navigate to view. Now click minimal interface.

·        Now you will have a constant stream on top of all your games.

Note: To view your surveillance streams live from anywhere around the world. Follow the camera manufacturer’s guidelines to enable the online setup. The process is easy to follow once you connect the PC to the internet router.

Difference between Hub and Switch

Difference between Hub and Switch 

Network devices, or networking hardware, are physical devices that are required for communication and interaction between hardware on a TCP/IP network.

Here is the common network device list:

·        Hub

·        Switch

·        Router

·        Bridge

·        Gateway

·        Modem

·        Repeater

·        Access Point

In 2006 The Network Hub is invented at Vancouver, British Columbia, Canada. A hub is a device that connects multiple Ethernet devices on one network and makes them act together as a single network. A hub does not gather information and input in one port results as an output in all ports on the network. A switch is a networking device that performs the same job as the hub but are considered as a more intelligent hub as it gathers information about the data packets it receives and forwards it to only the network that it was intended for. A Hub is a layer-1 device and operates only in the physical network of the OSI Model.

Hubs and switches are devices that are used in data networking on the internet. These devices are used in order to connect two or more networking ports in order to transfer data along the connection. Though the primary job of hubs and switches are the same, to forward data to different networks, they work in different ways.

A hub, also known as Ethernet hub, active hub, network hub, repeater hub or multiport repeater, is a device that connects multiple Ethernet devices on one network and makes them act together as a single network. A hub has multiple input/output (I/O) ports, in which an input in one port results in it being an output in all the other ports, except the port where it was input. In layman’s terms, a hub connects many networks into one, where a data packet that is sent by one networks, is copied and pasted to all network ports, making it so that every port can see that data packet. A hub works on the physical layer or layer 1 of the Open Systems Interconnection (OSI) model. It also works as a data collision detector, sending a jamming signal to all ports if it detects collisions at one port.

It is a simple device that does not examine the data it receives or sends, while just duplicating the data and making it visible for all. The receiving port that has to decide if the data packet is actually intended for it by checking the address on the packet, before passing it on further. Since hubs only have one collision domain, constant collisions occur. Unnecessary traffic is sent to all devices on the network. Originally hubs were popular due to the high price of switches, but switches are not so expensive these days. Hubs are slowly becoming obsolete in many practices, but are still used in special circumstances.

A switch is a networking device that performs the same job as the hub; it connects network segments or devices making them act as a single network. Switches are commonly referred to as a multi-port network bridge that process and routes data on a data link layer or layer of the OSI model. Switches can also process data at the network layer (layer 3) or higher layers and are known as multilayer switches.

Switches are considered as a more intelligent hub as it gathers information about the data packets it receives and forwards it to only the network that it was intended for. When a switch receives a data packet, it examines the data address, the sender and the receiver and stores the memory, after which it then sends the data to the device that the data is meant for.

Most modern Ethernet Local Area Networks (LANs) operate on switches. Small offices and residential devices commonly use single layer switch, while bigger applications require multilayer switches. The switches use a bridge or a router in order to split a larger collision domain to smaller collision domains, resulting in lesser collisions.  Each port has an individual collision domain, allowing computers to maintain dedicated bandwidth.

	Hub	Switch
Definition	A hub is a connection point for different segments of a LAN. It contains multiple ports and when it receives a packet of information at one port, it copies this packet to all segments of the LAN so that it can be viewed by all ports.	A switch is multi-port networking device that connects network devices together. A switch operates at the data link layer (layer 2) of the OSI model. A switch filters and then forwards data packets between networks.
Layer	Physical Layer (Layer 1)	Data Link Layer (Layer 2)
Spanning-Tree	No Spanning-Tree	It allows many Spanning-Trees to take place.
Type of Transmission	Broadcast	Broadcast, Uni-cast & Multicast.
Table	No MAC table. Hubs cannot learn MAC address.	Stores MAC address and maintains address.
Used in	LAN (Local Area Networks)	LAN (Local Area Networks)
No of Ports	4	24-48 depending on type of switch.
Collision	Occurs	No collision occurs
Collision Domain	One collision domain	Every port has its own collision domain.
Transmission Mode	Half duplex	Full duplex

Types of Hub

There are three types of the hub that are given below:

1.  Passive Hub

2.  Active Hub

3.  Intelligent Hub

Passive Hub: The passive hubs are the connection point for wires that helps to make the physical network. It is capable of determining the bugs and faulty hardware. Simply, it accepts the packet over a port and circulates it to all ports. It includes connectors (10base-2 port and RJ-45) that can be applied as a standard in your network. This connector is connected to all local area network (LAN) devices. Additionally, the advanced passive hubs have AUI ports, which are connected as the transceiver according to the network design.

Active Hub: As compared to a passive hub, it includes some additional features. It is able to monitor the data sent to the connected devices. It plays an important role between the connected devices with the help of store technology, where it checks the data to be sent and decides which packet to send first.

It has the ability to fix the damaged packets when packets are sending, and also able to hold the direction of the rest of the packets and distribute them. If a port receives a weak signal, but still it is readable, then the active hub reconstructs the weak signal into a stronger signal before its sending to other ports. It can boost the signal if any connecting device is not working in the network. Therefore, it helps to make the continuity of services in LAN.

Intelligent Hub: It is a little smarter than passive and active hubs. These hubs have some kinds of management software that help to analyze the problem in the network and resolve them. It is beneficial to expend the business in networking; the management can assign users that help to work more quickly and share a common pool efficiently by using intelligent hubs. However, it offers better performance for the local area network. Furthermore, with any physical device, if any problem is detected, it is able to detect this problem easily.

The important applications of a hub are given below:

·        Hub is used to create small home networks.

·        It is used for network monitoring.

·        They are also used in organizations to provide connectivity.

·        It can be used to create a device that is available thought out of the network.

Advantages of Hub

1. It provides support for different types of Network Media.

2.  It can be used by anyone as it is very cheap.

3.  It can easily connect many different media types.

4.  The use of a hub does not impact on the network performance.

5.  Additionally, it can expand the total distance of the network.

Disadvantages of Hub

1. It has no ability to choose the best path of the network.

2.  It does not include mechanisms such as collision detection.

3.  It does not operate in full-duplex mode and cannot be divided into the Segment.

4.  It cannot reduce the network traffic as it has no mechanism.

5.  It is not able to filter the information as it transmits packets to all the connected segments.

6.  Furthermore, it is not capable of connecting various network architectures like a ring, token, and ethernet, and more.

PoE NVR and PoE Switch

Difference between PoE NVR and PoE Switch?

Sir “I’m going to install two IP cameras in my house. However, I have no idea whether to use a PoE NVR or a PoE switch matching with them. So, what’s the difference between them? “

Hello “Arindam sir, this is XXX from BBB, as you are security expert, I realy confused from my cctv vendor, someone quote PoE based NVR someone quote PoE switch with Normal NVR. Please suggest which technology is best for us.”

Such type of questions I face throughout 2018, which indicates many people feel confused about the selection between PoE NVR and PoE switch. This write-ups / blog intends to explore the differences between PoE NVR and PoE switch in details.

What Is PoE?

PoE, an abbreviated form of Power over Ethernet, allows a single CAT cable connecting a power sourcing equipment (PSE) to provide both data connection and electric power to powered devices (PDs) such as IP cameras, wireless access points, etc.

What Is a PoE NVR?

NVR represents for network video recorder which provides you with centralized video controls to easily view, manage, and store your surveillance footage in one convenient location. A PoE NVR is a security video recorder with built-in PoE switch designed to use with PoE-based IP cameras.

Equipped with a PoE switch, a PoE NVR recorder can deliver both data and power over a single Ethernet cable. There is no need for an additional PoE switch, which will reduce the cost of equipment in theory. You just need to connect one Ethernet cable from the camera to the PoE NVR recorder and then the built-in switch will provide power to the camera while transmitting data.

A PoE NVR is ideal for users with minimal network administration experience and is generally used in homes and small businesses. It creates a private camera network, keeping surveillance footage isolated from the main network and adding an extra layer of privacy.

What Is a PoE Switch?

A PoE switch or power over Ethernet switch, containing multiple Ethernet RJ45 ports, is a dedicated network switch with multiple Ethernet ports to connect network segments and provide power and network communications.

It expands a network created by a router. Basically, it just assigns LAN IP addresses to your camera and needs to be tied into a system that allows you to see and manage your cameras, which is usually done with video surveillance software on a computer. Therefore, it must be connected directly to a router on the same network as your NVR. It can reduce the need for extra outlets and extension cables and saves deployment cost and labor efforts as well.

Power over Ethernet switch can be classified into many types. In addition to the most common one, gigabit PoE switch, for example, there are other types as well such as unmanaged and managed PoE switches. Most PoE switches provided in the market have standard gigabit Ethernet ports which can provide speed of 10/100/1000Mbps. For smaller network, 8-port Gigabit PoE switch is very popular. For larger/enterprise network, we use 24-port PoE switch and 48-port managed switch.

Main difference between a PoE NVR & PoE Switch

From the above, you will see that both PoE NVR and PoE switch can provide power and data transmission. However, the former is limited in minimal network administration experience while the latter can expend the network freely. What’s more, a switch does not assign IP addresses, which is the job of a DHCP server, usually built into a router. PoE NVRs provide this service, while PoE switches don’t. The switch simply provides a data path between all of the devices connected to it.

Note: You cannot plug a POE switch into an NVR directly - it must be plugged into your network.

Tips of Hanwha PoE NVR 

By default, PoE NVRs are set to connect directly to IP cameras.  In cases where the PoE ports are connected to network switches, the NVR must be put in Manual mode.

In addition, the PoE ports are set to Isolated mode, where each device can only communicate only with the NVR and not each other.  This is a security feature to prevent rouge devices from accessing other devices on the network.  This will prevent a connected PC from accessing IP cameras for setup changes.

If you are uplinking non-camera devices, such as switches, media converters, PCs, etc., you must set the NVR to Manual mode.

From the setup menu of the NVR, navigate to System > System Management > Settings > Load Factory Default.

Select the Manual Setup Mode.  If you wish to save some of the settings to speed up setup, check the Not Included options of User, Camera, and/or Network as needed.

Click the Initialization button and wait for the NVR to reboot.
