What Does MP Mean In CCTV Cameras?
MP stands for megapixels, which is a measurement of the resolution of the camera’s image sensor. A higher MP count indicates a higher resolution, enabling the camera to capture more detail in the images or videos. For instance, a 2MP camera can produce images with a resolution of 1920×1080 pixels (Full HD), while a 4MP camera can achieve 2688×1520 pixels. The greater the number of pixels, the finer the details that can be displayed in recorded footage.
Understanding MP is crucial for selecting the right CCTV system for your specific surveillance needs. Higher megapixel cameras are particularly beneficial in scenarios where details such as facial recognition or license plate identification are essential. However, it’s important to balance the MP count with factors like lens quality, lighting conditions, and storage capacity, as higher MP images require more bandwidth and storage space.
How Does The Choice Of MP Affect Image Quality?
The choice of megapixels directly influences the image quality captured by CCTV cameras. Higher MP counts can provide clearer and more detailed images, which can be crucial for identifying individuals or objects in the footage.
