YOGYAKARTA Closed circuit television (CCTV) is a digital video-based security system capable of recording events in certain areas directly. CCTV works differently, depending on the type of camera used.

CCTV can be installed indoors or in a closed place. The benefits are as follows:

Thus, it can be concluded that the installation of CCTV cameras can improve the security system and prevent criminal acts somewhere.

How CCTV Works

As mentioned above, CCTV works differently, depending on the type of surveillance camera used. However, in general, CCTV works by sending signals to the indoor monitor screen installed by CCTV cameras.

The signal is the result of recording the activities or events that took place at that time. Images recorded by CCTV will automatically be stored in a storage medium, as long as the storage media capacity is still available.

Originally, CCTV was divided into two types, namely CCTV analog and Camera Internet Protocol (IP). Well, Camera IP is divided into two types, namely decentralized and centralized IP Camera.

Compiled by VOI from various sources, Friday, October 13, 2022, here's how CCTV cameras work according to their types.

As the name implies, this surveillance camera uses the internet protocol (IP). The IP camera work principle is to send signals to the network using Cat 5 (wire with speeds of 10 and 100 Mbps Ethernet) and paint 6 (wire with speeds of 10 Mbps, and 10 gigabit Ethernet).

Furthermore, Cat 5 and Cat 6 will be sent to the network video recorder (Network Video Recorder (NVR) to store video recordings.

Then the recordings can be accessed through other devices such as cell phones or tablets, through an application that is usually provided by camera manufacturers.

The advantage of the IP camera is that it has a high resolution, at least 1080p. However, if you want to record it in a small resolution, you can too.

Wireless IP CCTV does not use network cables, making it easier to operate, aka more practical than CCTV IP.

The principle of the job is, CCTV cameras will work using wireless routers and the recording process is directly stored in the Micro SD memory. Then the recording results can be accessed through other devices such as cell phones or tablets, through an application that is usually provided by camera manufacturers.

The analog CCTV camera work principle is to send a signal to a digital video device via a▁pendidikanneil-concelman or BNC cable.

The system on an analog CCTV camera supports VGA or HDMI type outputs that make it possible to process monitor screen monitoring centrally.

CCTV with an analog system is currently still dominant and widely used in various places. The mention of CCTV is closely related to the analog system. This is because the analog system has existed decades ago.

The lack of analog CCTV lies in the limited quality of images that are not very good when viewed from the quality of images in the modern era. Most of the image quality produced by CCTV is also low in resolution, only 720 x 575 pixels also do not have digital zoom features.

That's how CCTV works based on its type. Hopefully it will be useful!
