the table below lists some of the more commonly used resolution terms in cctv applications. these terms may be used to describe the size of the image captured at the camera, transmitted over a wire, displayed on the screen, or recorded on the hard drive. those of you familiar with cctv know that the resolution of an analog camera is typically listed as “tv lines”. it is important to consider what platform your camera will be running on as that may limit your resolution options.
and keep in mind that the higher the resolution of the cameras, the more bandwidth and hard drive space you will need to transfer and store it. optiview’s recorders can be customized with the number of video channels, number of hard drives, analytics, and more. it’s useful to know that the human eye is more sensitive to horizontal resolution than vertical resolution. so make sure that the recording equipment you choose has at least the resolution capability of your highest resolution camera. just to be clear, the image may be captured and stored at megapixel resolution but transmitted by the recorder and displayed at qcif on the mobile device.
any robust security system includes high-quality surveillance cameras as an integral part of event tracking and monitoring. the primary function of your security cameras is to let you see events on your property, both recorded and in real-time. this might sound high, but the actual image quality is not good enough for digital zoom and enhancement. while higher resolution is more expensive, you get a lot more out of your security cameras when they can actually make out the details of an image. because digital zoom simply magnifies a portion of the image or video, you’re actually limiting your resolution to the size of that section. the same cropped section of the image contains more pixels, enabling you to make out more details.
instead of altering the resolution window, optical zoom changes the focal length of the camera’s lenses to tighten the field of view. to ensure full coverage with fewer cameras, you need something with a wider field of view. virtually any camera can come with a wide-angle lens, and some optical zoom cameras can zoom out far enough to essentially become wide-angle lenses. the catch is the massive distortion necessary to put the entirety of a room onto a comparatively small screen. the dewarping can do some strange things to the image resolution, but fisheye cameras aren’t designed to pull details. these systems stitch together multiple feeds to create a panoramic view instead of dewarping the image. regardless whether you choose high-zoom, wide-angle lens, panoramic cameras, or a mix of all three, you need a high enough resolution to ensure your surveillance system meets your needs.
