That is also how a CCTV camera is also, it is a camera that we already know about that it is also rated by its megapixel. The CCTV megapixel determines the video quality of the CCTV camera.

CCTV IP Camera

Many of us don’t know what a CCTV IP camera is, that is the reason why I include it in this article for us to know what it is all about. Before I begin, I want us to get this in our mind first so that wherever we see IP we will understand what it stands for. The word Ip means “Internet Protocol Camera” so wherever you see IP know that it stands for internet protocol camera because I don’t want anyone to get confused along the way.


Which is better IP camera or CCTV?

This is mainly used for surveillance, not like the analogue closed-circuit television which is (CCTV) cameras because it does not require local recording devices only local area networks.

CCTV Camera with DVR

Most of us did not know about this so-called CCTV camera using DVR. But with the little explanation, I will be providing you with, you will be able to get all that you need to know about the header you see above. Starting by explaining what DVR is and also tell you about NVR. Each security camera you see has its operating system like the one of DVR and NVR.

what a CCTV Camera and DVR looks like

DVR you see is a recording system same as NVR and they both stands for “Digital Video Recorder” which is for DVR. While the one of NVR stands for “Network Video Recorder”. Both of them have different ways of processing video data. One processes its video data at the recorder and that is the one of DVR, while one of NVR processes and encodes its video data at the camera. So, this is to say that the CCTV camera DVR processes its video data at the recorder and not at the camera which is the NVR system.

I want you guys to know this, what I want you all to know is that not every video recorder does work with every camera. The DVR needs an analogue camera, while NVR uses IP cameras.
