While purchasing a CCTV, the biggest confusing factor is whether to buy a simple closed circuit system, or to buy an IP or Internet protocol camera system. Both of these cameras are different from each other in terms of technology, price and other things. Both of them cater to different needs and services. You should know a little about both of them, so you could choose the right one for your needs.
Analog CCTV Cameras
These cameras work through an analog system. The transmission of the signal is done through cables. To receive the signal, you need a DVR recorder to record the footage being transmitted. The recording is all done in tapes. Every time the tape gets full it has to be changed, and the tape which is full can be re used after thorough reviewing of the footage on it. Recent advancements that have taken place in the analog department allow consumers to use the internet for signal transmission, but the picture quality remains the same, which not that great.
This system though, is cheap, but the costs add up to large amounts regarding the laying of the cable. The wires are complex, and have to be installed by an expert only. And there is also the damage that will take place during the installation of the wires. It ends up being a thorough pricey affair. Not to mention the fact, that this technology is being phased out and digital technology is replacing it everywhere.
The absolute latest in technology, these cameras use the internet to transmit the footage to the digital recorder. All the cameras are connected to the Local Area Network or better known as LAN, and each every camera has its own separate IP address. They are completely wireless, and the signal sent out is digital, hence, the quality of the picture is very good. This system is a network based system, which is ideal for big businesses. But a smaller and simpler version is also available for home security purposes.
With IP cameras, you can also log in from any remote part of the world where internet is available. All you need to have is a good password system that can help only you, and not others log into your connection. These cameras give great picture quality, which is the main function of a good security surveillance system. There is also the option of upgrading to high-definition cameras, which give the best picture quality possible.
These cameras also give the option of 2-way audio feature, which allows the person doing surveillance to talk to the person in front of the camera. It also record sound because it can be detrimental for the footage.
IP cameras and Analog cameras are miles apart. IP cameras are the better choice than the analog ones, but the analog one is also good at its work. So pick carefully, keeping in mind the features provided by each CCTV system.
