IP Telephony or Internet Protocol Telephony is a generic term used to describe technologies that use internet packets switched connections for exchanging voice, fax and other forms of information. The call propagates in the form of packets, over a local area network or internet avoiding PSTN Tolls.

The technology birthed in the late 1990s and drove the telecommunication industry to a change. Almost all communication carriers today are using an IP Infrastructure for a part or for all of its voice services.

The corporate environment benefits from IP Telephony in multiple ways, an important one being economic costing. IP Telephony trigged the development of unified communication solutions offering a holistic communication package as all in one, to be run on a single network & on one platform. This implies a business can make calls, manage video conferencing, collaborate, chat, etc. through a single service.

Now, coming to a very common misconception among people. Often, VOIP (Voice Over Internet Protocol) and IP Telephony are considered synonymous and the names are used interchangeably. The fact of the matter is, VOIP is a part of IP Telephony. Actually, IP Telephony deals with the digital side of telecommunications by means of an internet protocol known as voice over IP.

Another benefit of IP Telephony besides the cost is that of increased productivity. In fact, VOIP has been named the most successful technology of the last decade.


The first-ever mechanical CCTV Camera was developed in Russia way back in 1927. The development was originally made for Soviet of Labor & Defense consisting of a manually operated scanning transmitting camera paired with wireless short wave transmitter and receiver with a resolution of mere hundred lines. Yet another CCTV camera system was incorporated by Siemens AG at the test stand for Nazi Germany in 1942 in order to observe the launch of V2 rockets. The technology finally reached America in 1949 when a closed-circuit camera system by the name Vericon was introduced for commercial purposes.

The earlier CCTV System involved constant surveillance as recording hadn’t been invented yet. It was only in the 1970s when VCR technology was introduced that it became easy to record and erase info while video surveillance became more common. Moving to current times, we have seen a big leap in terms of advancement and now the internet based systems are quite common.

Coming to types of CCTVs currently present in the market, the most common ones are:

1. Dome CCTV Cameras

2. Bullet CCTV Cameras

3. C-mount CCTV Cameras

4. PTZ Pan Tilt & Zoom Camera

5. Day/Night CCTV Cameras

6. Infrared / night vision CCTV Cameras

7. Wireless CCTV Cameras

8. High Definition (HD) CCTV Cameras
