مقایسه تفاوت های Difference between IP CCTV and analogue CCTV

IP CCTV vs analogue CCTV

One of the most crucial things in business today is the security provision of premises. To help in solving this ever-difficult problem, CCTV cameras are emerging to be one of the most preferred alternatives in ensuring that the business of choice is secure. These CCTV cameras come with different classifications. The broadest of the choices that ought to be made is whether to choose an IP CCTV or to make use of an analogue CCTV. To know which is the best choice, it is important to understand how the two systems work.

The analogue CCTV has a camera that is used to capture video that comes in a specific traditional format. Upon capturing of video, these images are then transmitted live over a coaxial cable and stored in a tape such as a VHS, DVR or even the analogue video is digitized and stored in a hard drive.

The IP CCTV, on the other hand, is somewhat different from an analogue camera in that the cameras will capture video that is recorded by the camera and encode the video, which is then transmitted over an internet protocol as a digital steam, hence the term IP CCTV. In this case, no conversion occurs as works in the analogue CCTV. In the IP CCTV, a Network Video Recorder (NVR) ensures that all the cameras connected in the system are functioning and even controls the specific RAID drivers.

As you would have thought, the IP CCTV is superior to the analogue CCTV. One of the biggest differences between the two cameras is the clarity of the picture. In analogue CCTV, the picture is grainy and cannot specifically pinpoint a person of interest. The pixellation of the IP CCTV is quite good as the cameras can offer as high as 10MB of pixellation, meaning that the pictures shown are of high quality.

The network video recorder is also of superior quality over the previously used Digital Video Recorder (DVR). In NVR, each camera is an independent unit which can be viewed, controlled and recording can be individually stored. The NVR also allows users to access the content of the video and edit or even manipulate the content. In DVR, all this is not possible remotely, as the records are stored only in a small area.

When it comes to the security of the recordings, the IP CCTV is the best choice as opposed to analogue CCTV. This is because the IP CCTV has to encrypt all the files before storage, meaning it becomes very difficult to access the data being recorded unless you have the login details. In analogue CCTVs, all that is required is to have access of the CCTV and with that, you have access to all analogue recordings.

Another plus that makes the IP CCTV the better choice of the two is that the effect of distance. In great distances, the analogue CCTV will offer grainy and very vague picture quality. Using the IP CCTV, there is better picture quality, even when a specific person or item of interest is far.

In the analogue camera, all that is recorded is what is stored. This is not the case when it comes to the IP CCTV, as it offers the digital zoom feature, which means that the picture allows for zooming in, while the quality is maintained.

Summary


IP CCTV stores over recordings online
Analogue CCTV can only store locally
Picture quality is better in IP CCTV than with analogue CCTV
The picture of analogue CCTV can only be viewed locally, but IP CCTV recordings can be viewed remotely
Higher security of recording in IP CCTV as they are encryptedYou might also like…
