Motorized Zoom Cameras
Digital Zoom vs Optical Zoom
In the realm of security cameras, the distinction between digital zoom and optical zoom holds significance. All security cameras possess the capability of digital zoom, which proves particularly effective in high-definition cameras with resolutions of 1080P and beyond. However, the practicality of digital zoom is rooted in higher resolutions, as lower resolution cameras tend to produce pixelated results when magnified, rendering them inadequate for discerning details like faces or license plates from a distance. The general principle governing digital zoom is simple: the greater the camera's resolution, the higher the quality of its digital zoom. Among resolutions like 1080P, 3MP, 4MP, and 4K, the potential for digital zoom varies, with 4K offering the most intricate detailing.
Conversely, optical zoom pertains to the camera's physical optics responsible for zooming, distinct from the digital zoom facilitated by software in cameras or DVRs to "enlarge the image." Optical zoom represents the pinnacle of zoom quality, akin to utilizing binoculars to observe distant subjects. In optical zoom cameras, the camera's internal lens physically moves to achieve zooming. While digital zoom can be applied retrospectively to recorded video, optical zoom necessitates real-time activation during the actual occurrence of interest.
