![]() This means that higher-resolution cameras also automatically provide image streams (streams) at higher data rates. More details per image also simply means more data. This leads to motion blur, which unfortunately makes the most relevant part of the image unrecognizable: for example a quickly moving intruder. Low light sensitivity is often compensated for by longer exposure time. Also pay attention to the level of detail in moving pictures. Our advice:It is best to perform tests around the clock to determine whether the camera provides the details you need with the existing lighting. This in turn reduces the amount of light that is recorded by each pixel. For the same size imaging chip, as the resolution increases so does the number of pixels on the surface of the imaging chip, meaning that the surface area of each individual pixel becomes smaller. This saves costs not just for the cameras, but also for the installation and wiring.Ĭompared to low-resolution cameras (with the same size and technology of the imaging chip), high-resolution cameras are less sensitive to light, meaning they require more light to produce a clear, noise-free image. This makes it possible to replace multiple low-resolution cameras with one high-resolution camera. ![]() On the other hand, with one individual camera with a wide-angle lens, a larger scene can be recorded at the same level of detail. Larger surveillance area with fewer cameras This is one of the reasons to use high-resolution cameras. With identical camera position and viewing angle, more detail can be recognized, in particular when zooming in. The more dots (pixels) used to depict a scene, the more details will be visible. From lighting to bandwidth to storage capacity to playback performance – a large number of factors must be taken into account when deciding which resolution is right for the job: The use of cameras with higher resolution has some additional consequences. The benefits for video security appear to be clear: More details in an image either mean that fewer cameras can be used per monitoring scene or more information is available for image analysis.īut as is so often the case, the technically feasible is not always the same as the optimal solution. The sales argument: A completely new, impressively brilliant viewing experience. HD ready, Full HD, Ultra HD – what are the advantages of higher resolutions and what do they "cost"?Ĭonsumer electronics lead the way and video security plays catch up: Ever higher image resolutions become the new standard. A mediocre camera with a high-quality lens will in general provide better picture quality than a top-of-the-line camera with a cheap lens. Our advice:In practice, people often try to save with the lens – an unfortunate decision. Both of these components must be capable of handling the required resolution in order to achieve the best possible image quality for a camera. The maximum image resolution that a camera unit can provide depends on the imaging chip and the lens. The ratio of the number of horizontal lines to vertical columns determines the aspect ratio.
