Disadvantages analog flashlight friends camera system (CCTV) obsolete technology (sale of component

At the beginning of this article we would like to explain the concepts of analog CCTV and IP (digital) camera system. Unfortunately the day we meet with customers (of course), as well as with colleagues flashlight friends in the industry (inexplicably) with ignorance, because that confuses the concepts and technology, inventing different names and combine what actually combine flashlight friends or not possible.
What is actually an analog camera system, known as CCTV? This shortcut is a "Closed Circuit Television" in translation ie "Closed Circuit Television". The first commercial exploitation dates back to 1985. At the very beginning it was a relatively simple system consisting of analog cameras, cabling, recording equipment and analog monitor. The cameras panned the selected area, which was then deposited on the recording equipment and evaluated on monitors or televisions. The system did not have a digital component with PC or cell phone. This was because, as already mentioned, by closed circuit television.
Later came the market flashlight friends DVR system flashlight friends (Digital Video Recorder). Translated into English as "digital video recorder". Here we can mention flashlight friends digital device, through which you can connect the camera system to a network, consult the live image and evaluate the results using a computer, at best, and using a mobile phone. Unfortunately for digitization in poor image quality due to the compression used. In today's "retouching" time, such a record is not considered credible because it is very low resolution and the offender is possible only difficult to identify, even under ideal lighting conditions.
Benefits flashlight friends analog camera system (CCTV): Low start-up costs can be up to 1.3 megapixel cameras with SDI, the highest range (approximate price as the IP cameras) Easy installation and operation (in small systems)
Disadvantages analog flashlight friends camera system (CCTV) obsolete technology (sale of components in the development of leading brands terminated) limited the resolution flashlight friends to PAL / NTSC or SDI, a maximum of 1.3 megapixel individual system components depend on the recording equipment, flashlight friends the failure of the recording equipment is complete security system and discard the CCTV is not possible to connect significantly increasing costs for the more challenging installations cameras placed at greater distances from the recording devices are susceptible to interference of neighboring networks and hence the jamming signal by which the offender system virtually exclude no audio (analog flashlight friends cameras can not send audio) cable from the camera must lead directly to a recording device total price analog CCTV system in the same quality as the IP is almost the same nowadays are more like a "scarecrow"
Now let's flashlight friends look at the relatively new technology of IP camera system. The difference in the title instead of IP CCTV is the reason that the IP camera systems are based on Internet Protocol technology, respectively. flashlight friends technology on a computer network. Note that the title is also not mentioned "Close" or "Manual". IP camera system is not closed, or somehow limited and does not resemble a closed circuit principle. Unless something happens with the recording equipment NVR (Network flashlight friends Video Recorder), IP cameras are still working and can connect flashlight friends to them directly. On some models can even set the record on a memory card as redundant storage space, and you will not lose record. This is of course only one of a number of advantages.
Benefits of IP CCTV system: new technology, flashlight friends constantly perfecting unlimited-resolution IP cameras, conventional HD, FULL HD, 2MP, 3MP, and above 5 megapixel IP camera is not dependent on the recording equipment works seamlessly and independently connectivity up to 100m without extra costs or use "repeater" IP cameras recorded the audio track simple use of wireless data communications (suitable for elevator cabs) the total cost of the system is similar to the CCTV camera system similar quality
Finally, I just pointed out an important fact when considering the establishment of a CCTV system, well you're wondering which technology you choose. To deter the offender only, the market offers a dummy cameras, you do not throw money for analog systems. However, if you want to protect your property so that it can be offender apprehension, then there are IP camera systems.
