As the resolution increases, so does the need for having a larger hard disk to meet minimum requirements for recording. This is critical for most applications because at such a high specification, understanding how much data you need is important to maintain a trove of recordings that are practical to requirements of the client.

A lens is a shaped piece of transparent glass or plastic that refractscloserefractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. light. When light is refracted it changes direction due to the change in density as it moves from air into glass or plastic. Lenses are used in cameras, telescopes, binoculars, microscopes and corrective glasses. A lens can be convexcloseconvexAn object or shape that curves or bulges outwards, like a circle or sphere. or concave.

In a ray diagram, a convex lens is drawn as a vertical line with outward facing arrows to indicate the shape of the lens. The distance from the lens to the principal focus is called the focal lengthclosefocal lengthThe distance between the centre of the lens and the focal point..

Thirdly, equipment matters when it comes to getting the full 5 megapixel resolution. Some suppliers might quote you a 5 megapixel camera with a 2 Megapixel recorder which also means that you only get 2 MP out of 5 MP equipment. They do this so they are able to oversell their specifications. Hence, its important to note that when u have a 5 megapixel system, its important to ensure that the system is properly installed by a certified professional.

In a ray diagram, a concave lens is drawn as a vertical line with inward facing arrows to indicate the shape of the lens.

Firstly a brief understanding of 5 megapixels. 5 Megapixels of resolution roughly translates to 2560 x 1920 pixels of resolution. With such a resolution, it will take normally a UHD TV set or a high specifications phone to render such an image quality.

In terms of recordings, at H.264 compression, 24 hours of recordings at 15 FPS (frames per second) will take 52GB of data. At H.264+ compression, 24 hours of recordings at 15 FPS (frames per second) will take 26GB of data. Hence 2TB of data will support the recorder for 19 days.

A convex lens is thicker in the middle than it is at the edges. Parallel light rays that enter the lens convergecloseconvergeMove towards each other.. They come together at a point called the principal focus.

Secondly, with the increase in resolution, a higher bandwidth is needed to view the cameras. What i means is that it will require more internet speed to see the cameras clearly and smoothly. With clarity comes the need for higher internet speed so that the video images can be loaded faster. For 4 cameras of 5 megapixels in resolution, the bandwidth needed is 9 MBPS (after compression).

A concave lens is thinner in the middle than it is at the edges. This causes parallel rays to divergeclosedivergeWhen a light ray splits up or spreads out. . They separate but appear to come from a principle focus on the other side of the lens.
