For conventional video surveillance cameras, analogue cameras or the different formats in which the television signal output is analogue, TV lines are used to refer to the image resolution that the camera can capture and deliver. The resolution of the image depends mainly on the image sensor with which it is equipped, either CCD / CMOS. Based on different CCD / CMOS image sensors, analogue cameras can offer standard resolution video with 1000 TVL, 700TVL, 650TVL, 480TVL, 420TVL TV line, the higher the number of lines, the higher the Resolution. The doorbell camera reviews help you to get a doorbell.

Now, network security cameras are an increasingly used alternative, giving a Digital Video output, and using the number of pixels to refer to the image resolution, so, we find 0.3 megapixels, 1 megapixels, 1, 3 megapixels, 2 megapixels, 3MP, 5MP, 8MP even higher resolutions/definition. Higher number of pixels means better image quality and higher resolution. A television line is a different vertical line, alternately in black and white, which theoretically can be displayed on a video image from a camera or on a screen. Thus, 400 TVL would mean that 200 alternate dark lines and 200 clear vertical lines can be captured/displayed by the camera/monitor. Look at these doorbell camera reviews.

Likewise, the recording devices DVR, NVR, and video storage units, also have a different resolution to define their video compression capacity, such as QCIF, CIF, HD1, D1 (FCIF), 960H (WD1), etc. An analogue video surveillance system consists mainly of several cameras and a Recording / Control unit, DVR. To obtain the required video quality, both equipment, cameras and DVR recorder must have at least the same resolution specification and even the DVR recorder should have a higher resolution. The resolution of the doorbell camera reviews is the number of pixels that make up the screen and is specified by the number of pixels on the horizontal axis and the vertical, for example, 1024 × 768. The more resolution we have, we get better-defined graphics and letters, in addition to fitting more information on the screen at the same time.

With the term High Definition (HD) we refer to the resolution of megapixels. Currently, we also find UHD – Ultra High Definition (4K), or 4 times 2MpX (HD), with 8-megapixel sensors. Also in the viewing of these images, either directly from the camera or through the recording unit, we find monitors with Aspect Relations, such as, for example, 4: 3, a television format that we know traditionally, although it is no longer in use, almost quadrangular (used for standard resolution systems, computer monitors).

The “FULL” indication refers specifically to the “16: 9” aspect ratio (used in High Definition systems, and Smart Terminals), also called cine or widescreen format. This format allows you to see more and better because the 16: 9 format exceeds the 4: 3 format by 30%. We also find the term, FullHD, which indicates HD images in a format or aspect ratio of 16L: 9W, in pixels, 1920 (H) x 1080 (V).

Doorbell camera reviews:

Aspect Ratio: The ratio of the screen or aspect ratio is the proportional relationship between the width and height of an image. This is generally expressed in a “Width: Height” format, so, for example, the ratio of 16: 9 means a width of 16 units and a height of 9 units. There are two main standards in the aspect ratio, 4: 3 and 16: 9.
