For many decades, EPABX was considered as the most viable mode of business communications. They were built on copper wires and run on POTS (Plain Old Telephone Services). Talking about the contemporary scenario, businesses want to expand their potentials and revamp internal & external communications. Therefore, the arrival of IP PBX has turned around the tables. An IP PBX is a PBX phone system that uses internet protocol instead of the traditional analog services. This blog will help you give a comprehensive discussion on IP-PBX vs EPABX or why to choose IP telephony (VoIP phones) over traditional PBX systems to carry out business communications. 

1. Installation is not at all tiresome task!

Since VoIP phones are internet-based phone systems, the set up or installation is quite easy. Same network will be used for data and voice (connected via LAN) only.

On the other hand, with EPABX, installation through TDM cables sometimes becomes an issue. Apart from this, if you have decided to relocate your office, setting up an EPABX requires complete rewiring.

2. Maintenance/Configuration of IP PBX is just so simple!

In case of IP PBX phone systems, they come with easy to use web-based configuration interface. This makes them easy to manage or configure phone systems remotely. Any update in the software can be done via admin remotely.

While with EPABX, in case there arises any sort of technical issue, the person will have to go at that place physically in order to resolve it.

3. Scalability gets a new turn!

Traditional EPABX has limitations when it comes to expansion. Adding more phone lines means adding new cards into the system (It will require additional physical slots into the chassis). With IP telephony, it’s very simple to add new extensions. By adding a simple license, you are good to go.

Also, Traditional EPABX is bulky in size. It requires a lot of space (almost the size of a big cupboard), while IP PBX can easily fit into a network rack.

4. Integration with Productivity Tools:

Integration with business continuity apps, like CRM, outlook, email, IoT, Artificial Intelligence, API(s), CTI, etc. is possible with IP-based PBX only.

5. VoIP Support:


With VoIP softphone, you can use desktop or your smartphone for making calls using VoIP service. This implies that the costs spent on phone equipment can also be easily eliminated with softphones, which can be integrated with IP PBX. The same is not in the case with traditional EPABX.

Inter-Office Connectivity

Communications within the same organization, but located at different geographical locations, is possible only with IP based PBX. IP-PBX allows inter-office connectivity.

6. Business Continuity:

IP PBX also has following two benefits:


We can setup a backup IP PBX server, so that in case of fault, it will immediately switch to other server to maintain business continuity. This helps in achieving maximum up-time.


Virtual PBX can be run on the same servers as other business applications in virtualized data centers for better ROI of purchased Infra.

7. Advanced Features which are quite impressive!

Talking about traditional analog phones, they come with really basic functions. But the way businesses operate today with the aim of surpassing customer’s expectations, the business phone systems should be the winner in the competitive ground. IP telephony comes with features, like- auto attendant, IVR, call recording, voicemail to email, LCD display, Multi-line keys, Softkeys, pre-programmable keys, PoE (Power over Ethernet), multiple LAN ports, video calling functionalities, unified messaging, contact center functionalities, mobile accessibility, audio conferences, teleworker and the list still continues.


A connected workplace is a key to a successful business. The above discussion gives a clear indication that IP telephony (IP PBX) builds a more mobile and collaborative environment, which not only promotes business efficiency, but makes a clear way to work productivity.

When you purchase an IP camera, it’s necessary to make it work in your network and sometimes this task can be daunting for beginners or inexperienced users.

No worries, configuring an IP camera is not rocket science. There are a lot of different IP camera brands out there, but the configuration process is similar to all of them. In this article, I will teach you how to configure Hikvision IP camera.

IP camera network diagram

OK, the first thing I want to show you is how an IP camera can be part of your network. Looking at a diagram is the easiest way to understand how this device is connected and what are the other elements of the network.

As you can see, this is a pretty basic diagram which has an IP camera, a PoE switch and a laptop connected together. An alternative to that diagram it to replace the switch with a router, in that case, you need to use a power supply to the camera.

Take a look again at the diagram. Can you see a lightning bolt symbol close to the IP camera? I put it there to let you know the camera is powered up by the UTP (network cable), so there’s no need for an extra power supply.

PoE stands for Power Over Ethernet and that’s a universal standard to send power to IP devices. If you don’t know what I’m talking about, I highly recommend you to read the article: PoE switch for IP cameras.

Hikvision IP camera software

To configure your Hikvision IP camera is necessary to use a web browser such as Internet Explorer or you can use a software such as the Hikvision SADP tool.

In this article, let’s focus on the SADP that allows you to configure multiple IP cameras in the network, you just need to download it and install in your computer.

The idea is to use such software to find your Hikvision IP camera in the network.

Hikvision SADP download

The Hikvision SADP tool is available at the manufacturer website, you can download the last version by clicking on the link below:

How to use Hikvision SADP tool

Download and install the SADP tool in your computer and just open it up to start the Hikvision IP camera configuration process.

If your IP camera is correctly connected to your network it might get an IP from your router. If it doesn’t, you can find the camera with its default IP address which is You can see that in the SADP tool.

The picture shows that the SADP tool found the Hikvision IP camera in the network and the IP is, the communication port is 8000.

There’s also the information for the subnet mask which is and the IPV4 gateway that is not configured yet and shows:

If you not familiar with the IP network address scheme. Just ignore the IPV4 gateway information if you don’t want to have the IP camera available on the Internet, but if that’s the case. just replace the with your local router IP address.

ee the picture below with the camera IP changed to

Open the camera via a web browser

After configuring the Hikvision IP camera address, just open a web browser such as Google Chrome, Mozilla Firefox,  or Internet Explorer and type the camera IP address in the URL bar.

If this is the first time you are trying to have access to a Hikvision camera, your browser will ask you to install a plugin (see the picture below).

Just click on the link to download and install the plugin and you will be able to see the camera live streaming directly into the browser.

And that’s the live view streaming directly into the browser…

Hikvision IP camera gateway configuration

Alright, now you have your Hikvision IP camera working in the local network.

But perhaps you are wondering how to have remote access to the camera from the Internet. and that’s also something simple to deal with.

The first thing you need to do is to configure the camera gateway, which basically means you are telling the camera who is the device it should send the traffic to when going to the Internet. This device is your Internet router.

Just open the Hikvision SADP tool again and configure the IPV4 gateway with the IP address of your router (see the picture below).

How to find the gateway information (IP)

Just in case you don’t know how to find your computer or gateway (router) information, you can use the command prompt to find it out.

Click on the windows search bar, type CMD, and click the Command Prompt.

The next step is to type the command ip config in to see the information about your computer IP address and gateway, see the picture below for the details.

The default gateway is the router’s IP, meaning your computer has such information and that’s the reason it can reach the Internet (by sending packets to the router). The idea is that your IP camera could do the same.

As long as you configure the camera with the correct gateway information (as described earlier) it will be able to send and receive packets from the Internet, however, you need to follow the steps to configure your mobile phone for that…

Hikvision IP camera remote access

That’s all. Now you have all the information on how to configure Hikvision IP camera in the network, If you want to take the next step you to have remote access to the camera using your mobile phone, just read the article: How to access Hikvision DVR from mobile. Besides the fact the article teaches how to configure remote access for a Hikvision DVR, it also works for IP cameras.

If you are a professional that is really interested in learning even more about other details of IP networks for CCTV, just take a look at the Ultimate Security Camera Guide Volume 3 which teaches everything you need to know.

What is fire?

Photo: Fire is a chemical reaction that needs activation energy to start it off, provided by something like a match, the heat of the sun, or an overheating machine.

Ask most people what a fire is and they’ll tell you it’s something frightening and destructive involving flames. But to a scientist, a fire is something much more precise. A fire is actually a chemical reaction called combustion. When combustion happens, substances like woodpaper, oil, or coal (all of which are made from chemicals, even if you don’t immediately think of them that way) combine with oxygen in the air to produce water, carbon dioxide, waste gases—and an awful lot of heat. Combustion doesn’t normally happen all by itself: things don’t burst into flames without help. It usually takes some activation energy (provided by a spark or a match) to kick off the reaction. Once combustion is underway, the fire seems to continue all by itself.

The fire triangle

Photo: You need to to take away one or more of heat, air (oxygen), or fuel to break the triangle and put the fire.

That’s not quite true. Fire happens when three things are in the same place at the same time:

  1. Fuel (something to burn—such as wood or coal).
  2. Oxygen (usually from the air).
  3. Heat.

A fire can burn when all these things are present; it will stop when at least one of them is removed. As any fire-fighter will tell you, putting out a fire involves breaking the fire triangle—which means removing either the fuel, the heat, or the oxygen. Suppose a fire breaks out in a pan on top of your cooker, the first thing you normally do is switch off the heat. If that doesn’t work, you might soak a towel with water and place it very carefully over the pan (or, better still, use a fire blanket). The towel is designed to block off the supply of oxygen to the fire (the water stops the towel from catching fire and making things worse). Every fire-fighting technique you can think of involves removing heat, oxygen, or fuel—sometimes more than one of those things at the same time. Fire extinguishers work by removing heat, air, or both.

Types of fire extinguishers

Photo: Some extinguishers have pressure gauges on top so you can check they’re correctly pressurized and safe to operate. If the pressure is either too high or too low, the needle moves into the upper or lower red zone. On this dry-powder extinguisher, the needle is right in the middle: still safely in the green zone, pressurized to about 14 times atmospheric pressure (the normal pressure of the air around us).

There are three main types of extinguisher and they work in slightly different ways:

  • Water extinguishers, which are the most common, are essentially tanks full of water with compressed (tightly squeezed) air as the propellant to make them come out. Water extinguishers work by removing heat from the fire.
  • Dry chemical extinguishers are tanks of foam or dry powder with compressed nitrogen as the propellant. They work by smothering the fire: when you put a layer of powder or foam on the fire, you cut the fuel off from the oxygen around it, and the fire goes out.
  • Carbon dioxide (CO2) extinguishers contain a mixture of liquid and gaseous carbon dioxide (a nonflammable gas). CO2 is normally a gas at room temperature and pressure. It has to be stored under high pressure to make it a liquid. When you release the pressure, the gas expands enormously and makes a huge white jet. CO2 attacks the fire triangle in two ways: it smothers the oxygen and, when it turns from a liquid back to a gas, it “sucks” in a massive amount of heat from its surroundings (the latent heat of vaporization), which cools whatever you spray it on by removing heat.

That classifies extinguishers by what they contain. You’ll also find fire extinguishers classified by the types of fires you can use them on. This gives us five different kinds:

  • A: Green: For wood, cloth, and paper.
  • B: Red: For combustible and flammable liquids such as oil, gasoline, and paint.
  • C: Blue: For electrical equipment and tools.
  • D: Orange:: For flammable metals.
  • K: Black: For animal or vegetable oils or cooking fats.

It’s important always to use the right extinguisher for the fire. Using the wrong extinguisher can put your life in danger and make the fire worse. For example, you must never use water extinguishers on electrical fires because you could electrocute yourself and the people nearby. If you’re in the slightest doubt about tackling a fire, leave it alone and get yourself to safety.

Not only is it smart to keep fire extinguishers in your home, it’s also the law in many states.It’s important to make sure you have the right types of fire extinguishers on hand to put out common household fires. Read our fire extinguisher safety tips to learn how to stay safe and don’t forget to make sure you have the right coverage if your home sustains fire damage. Getting started with fire extinguishers

The first thing to do when choosing a fire extinguisher is to decide which rooms in your house need one. You should keep at least one on each level of your house. Make sure you keep fire extinguishers handy where fires are more likely to start, like in the kitchen and garage.

Understanding fire extinguisher classes

There are four classes of fire extinguishers – A, B, C and D – and each class can put out a different type of fire.

  • Class A extinguishers will put out fires in ordinary combustibles such as wood and paper
  • Class B extinguishers are for use on flammable liquids like grease, gasoline and oil
  • Class C extinguishers are suitable for use only on electrically energized fires
  • Class D extinguishers are designed for use on flammable metals

Multipurpose extinguishers can be used on different types of fires and will be labeled with more than one class, like A-B, B-C or A-B-C.

Purchasing your fire extinguisher

Now that you know how many extinguishers you need and what types to get, you can head to the hardware store. Look for fire extinguishers that you can easily lift. Larger extinguishers may pack more power, but you must be able to use it properly.

Learning how to use your fire extinguisher

Once you’ve made your purchases, familiarize yourself with the fire extinguisher directions so you’ll be prepared in case you need to put out a fire. Typically, fire extinguishers are fairly easy to use in the case of a fire. Most of the types operate using the P.A.S.S. technique:

  • P. Pull the pin on the fire extinguisher in order to break the tamper seal.
  • A. Aim the fire extinguisher low, with the nozzle pointed at the base of the fire.
  • S. Squeeze the handle of the fire extinguisher to release the extinguishing agent.
  • S. Sweep the nozzle from side to side while pointed at the base of the fire until it is extinguished.
  • If the fire re-ignites, repeat the last 3 steps.

Ensure you and your home are protected in case of a fire or some other household accident with homeowners insurance.

Your Internet service provider is the company that provides you with your Internet connection. For example, your ISP may be Comcast, Time Warner, or whatever other company you’re paying each month.


A local area network is a small network that’s confined to a local area. For example, your home network or an office network is a LAN.


A wide area network is a larger network that covers a wider area. Your ISP provides you with a connection to their own WAN, which connects to the Internet.

IP Address

An Internet Protocol address, or IP address, is a numerical address that corresponds to your computer on a network. When a computer wants to connect to another computer, it connects to that computer’s IP address.

IPv4 and IPv6

There are two types of IP address in common use. Older IPv4 (IP version 4) addresses are the most common, followed by newer IPv6 (IP version 6) addresses. IPv6 is necessary because we just don’t have enough IPv4 addresses for all the people and devices in the world.


A router is a device that passes traffic back and forth. You likely have a home router. It’s that router’s job to pass outgoing traffic from your local devices to the Internet, and to pass incoming traffic from the Internet to your devices.


A gateway is a device that routes traffic between networks. For example, at home, your router is your gateway. It provides a “gateway” between your LAN and WAN.


Network Address Translation, or NAT, is used by routers to share a single IP address among many devices. For example, you probably have a wireless router at home that creates a Wi-Fi network your laptops, smartphones, tablets, and other devices connect to. Your ISP provides you with a single IP address that’s reachable from anywhere on the Internet, sometimes called a public IP address.

Your router creates a LAN and assigns local IP addresses to your devices. The router then functions as a gateway. To devices outside your LAN, it appears as if you have one device (the router) using a single IP address.


The dynamic host configuration protocol allows computers to automatically request and be assigned IP addresses and other network settings. For example, when you connect your laptop or smartphone to your Wi-Fi network, your device asks the router for an IP address using DHCP and the router assigns an IP address. This simplifies things — you don’t have to set up static IP addresses manually.


A hostname is a human-readable label that points to a device connected to a network. For example, on your home network, your Windows computer’s hostname may be WINDOWSPC. Your other devices can connect to WINDOWSPC and will be pointed at that computer’s local IP address.

Domain Name

Domain names are the base part of website names. like howtogeek.com or google.com. Note that domain names are just another type of hostname.


The domain name system is how computers convert human-readable domain names and hostnames to numerical IP addresses. When you type howtogeek.com into your web browser’s address bar, your computer contacts its DNS server and the DNS server replies with the numerical IP address of How-To Geek’s server, which is what your computer connects to.

You’re likely using your ISP’s DNS servers by default, but you can use third-party DNS serversif you prefer.


Ethernet is the standard wired network technology in use almost everywhere today. If your computer is connected to a network via a cable, it’s likely using an Ethernet cable. That cable plugs into an Ethernet port on your computer.

Network Interface / Network Adapter

Your computer’s wired Ethernet connection and Wi-Fi connection are basically both network interfaces. If your laptop was connected to both a wired connection and a Wi-Fi network, each network interface would have its own IP address. Each is a different connection.

Network interfaces can also be implemented entirely in software, so they don’t always directly correspond to hardware devices.


The hostname “localhost” always corresponds to the device you’re using. This uses the loopback network interface — a network interface implemented in software — to connect directly to your own PC.

localhost actually points to the IPv4 address or the IPv6 address ::1 . Each always corresponds to the current device.

MAC Address

Each network interface has a media access control address, or MAC address — also known as a physical address. This is a unique identifier designed to identify different computers on a network. MAC addresses are usually assigned when a manufacturer creates a network device.

For example, when you visit an airport and use 30 minutes of free Wi-Fi before being kicked off and refused access to further Wi-FI without paying, the airport’s Wi-Fi network has likely noted your device’s MAC address and is using it to track your PC and prevent you from taking advantage of more free time. MAC addresses could also be used to assign static IP addresses to specific devices, so they’d always get the same IP address when they connected to a router with DHCP.

MAC addresses are actually more fluid in practice, as you can change your network interface’s MAC address. (Yes, this means you can often gain access to more free airport Wi-Fi by changing your device’s MAC address.)


When an application wants to send or receive traffic, it has to use a numbered port between 1 to 65535. This is how you can have multiple applications on a computer using the network and each application knows which traffic is for it.

Standard HTTP uses port 80, so when you’re connecting to http://howtogeek.com, you’re really making an HTTP connection to port 80 on howtogeek.com. The web server software on howtogeek.com is listening to traffic arriving on port 80. You could attempt to connect on port 81 by plugging http://howtogeek.com:81/ into your web browser, but you wouldn’t get a response because the web server software isn’t listening on port 81.

Protocol – TCP, UDP, ICMP, etc.

Protocols are different ways of communicating over the Internet. TCP and UDP are the most common protocols. The ICMP protocol is also used, but primarily so network devices can check each other’s status. Different protocols are ideal for different types of communication.


A packet is a unit of data sent between devices. When you load a web page, your computer sends packets to the server requesting the web page and the server responds with many different packets of its own, which your computer stitches together to form the web page. The packet is the basic unit of data that computers on a network exchange.


firewall is a piece of software or hardware that blocks certain types of traffic. For example, a firewall could block incoming traffic on a certain port or block all incoming traffic except traffic coming from a specific IP address.


The hypertext transfer protocol is the standard protocol modern web browsers and the web itself uses. FTP and BitTorrent are examples of alternative protocols.


A uniform resource locator, or URL, is also known as a web address. The current URL is displayed in your web browser’s address bar. For example, http://howtogeek.com/article is an URL that tells your computer to use the hypertext transfer protocol HTTP to connect to the server at howtogeek.com and ask for the file named article in the root directory. (The computer contacts its DNS server to find the IP address howtogeek.com is associated with and connects using the TCP protocal on port 80.)

Due to increase in crime in city areas and on highway the authority or government has to focus on vehicles moving on the road. And the best way to get information about particular vehicles is to record it’s number. But problem with normal CCTV system is of “frame rate”. Normal CCTV Camera have maximum Frame Rate of 20fps. But to read and record vehicles number of a fast moving car or Bus we need a camera having Frame Rate around 40-55 fps.

A Normal CCTV camera setup consists of camera, wire, DVR, Storage and Display. But a NPR Camera setup consists of camera + NPR Software. We also need a PC so that we can install the software and use it after connecting the NPR Camera to the computer or the local network. Price of a NPR Camera starts from 2.5 Lakhs. These type of product also need expert technician or Engineer.

Reliable license plate recognition (LPR) has traditionally been costly and only relevant for a limited number of applications.

The rapid development of IP cameras now allows for wider use of automatic LPR solutions. Depending on your needs, they can help to increase everyday efficiency, service levels or security.

Automatic recognition and actions

Our LPR solutions are based on an Axis camera and partner software that runs either on the camera or on a server. It automatically captures the license plate in real time, compares or adds it to a pre-defined list and then takes appropriate action such as opening a gate, adding a cost, or generating an alert.

Depending on surrounding light, the solution may require cameras with built-in IR-light or additional light sources for optimal performance.

       Wide range of applications

Automatic LPR is a valuable solution for multiple applications, including:

  • Parking management where it facilitates – or even automates – payment, entry and exit
  • Toll roads, to enable free-flow through toll plazas
  • Airport traffic management, to ensure that only authorized vehicles can access the taxi / public transport lanes
  • Access control, where the gate is only opened for authorized vehicles and all visiting vehicles automatically are registered
  • Vehicle alerts, where the solution provides an automatic alert when any of the vehicles on a watch list passes by
