What Exactly is DVR?

The abbreviation DVR stands for Digital Video Recorder. As the name implies, these systems utilize a hard disc drive to digitally record and store security footage.

It enables you to capture higher-quality movies. A DVR is essentially a VCR that stores its recordings on a hard disc rather than videotape. It is capable of recording, storing, and playing back television shows.

Unlike IP cameras, DVRs, on the other hand, do not link directly to the internet. They are a closed-circuit system, communicating locally and not with other external networks.

Additionally, a DVR can pause live television by recording the current show simultaneously. The user can select to fast forward to live television (typically during advertisements).

What Is the Purpose of a DVR?

DVRs use to record tv shows and movies for later viewing. Typically, you can programmed your DVR to monitor individual programs or events as they air.

If you have a favorite show, you may configure your DVR to record only new episodes and remove older ones automatically. DVRs equipped with multiple tuners can even capture various channels concurrently.

DVR Types

DVRs come in various sizes, ranging from small pocket-sized units to big PC-sized units. Additionally, a few DVRs can be connected to an external network, allowing for remote viewing of the recorded film.

The Three Major Types of DVRs are as follows:

Embedded Digital Video Recorders

It is a stand-alone device that accepts analogue CCTV camera inputs and compresses the data before storing it on a local hard disc. The operating system and software include a chip, and it consists of a hard disc drive for picture storage.

Embedded DVRs run an in-house operating system that is not accessible via external networks. It makes them less susceptible to viruses, hackers, and other hostile attacks, increasing their security.

Hybrid DVRs

These DVR CCTV systems can receive video inputs from CCTV and IP cameras. These can seamlessly move from an analogue to an IP-based monitoring system.

PC-based DVR

As the name implies, a PC-based DVR integrate into a personal computer. It equips with a network card, motherboards, video boards, a digital video recorder capture card, and a memory drive.

The primary advantage of this form of DVR is the ease with which the memory space can be upgraded and expanded by putting more hard disc drives into the device.

Main Resolutions on DVR

The following are the major resolutions in rising order of quality.

CIF Resolution 

CIF is the lowest quality format and uses a 352 by 288-pixel frame size. Half D1, sometimes referred to as “Field” or 2 CIF, has a resolution of 704 x 288 pixels. D1 has a resolution of 704 × 576 pixels.

960H has a resolution of 960 x 576 pixels. 960H and D1 are identical resolutions. D1 possess a 4:3 aspect ratio, 960H has a 16:9 aspect ratio, and the additional pixels fill in the image’s border. There is no difference in terms of resolution or pixel density.

720P and 1080N

720P refers to a resolution of 1280 × 720 pixels or 0.9 megapixels. It is the smallest HD resolution available.

The Resolution of 1920 x 1080 pixels, or 2.1 megapixels, is 1080P. All of our high definition goods are 1080P.

Resolution 1080N

It is a slight deception. While HD 1080P and 1080N may sound similar, they are pretty different. HD 1080P has a resolution of 1920 by 1080 pixels or 2.1 megapixels. The 1080N, on the other hand, has a resolution of 1080 by 960 pixels (1 megapixel). Avoid being caught off guard.

3MP, 4MP, and 4K Resolutions

HD1080P is sufficient to produce excellent photos when the cameras zoom in. 4MP reduces storage time in half but results in a 40% “increase” in image quality.

While 4K doubles the image quality theoretically, it requires eight times the hard drive capacity. 21 days of HD 1080P rolling film becomes 2.6 days in 4K. 

960H Resolution for Recording

960H features have a better resolution than normal D1, yet this is not the case. 960H is identical to D1 in Resolution but has a 16:9 aspect ratio rather than a 4:3 aspect ratio. It is a widescreen standard definition presentation.

1080P High Definition

Compared to standard definition CCTV, HD1080P offers a 2.1-megapixel resolution, allowing you to capture more detail or cover a larger area with the same quality. Combining HD1080P with the
