The sharpness of your CCTV images is expressed by a number called resolution. The resolution has a major impact on the top-end quality of any given camera’s image. It also plays a role in storage space and ultimately should be a factor in choosing what kind of closed-circuit television, or CCTV, equipment suits your location’s particular needs. If you’re at all unsure of how this plays a part in CCTV, or camera tech, read on to learn more about the awesome high-resolution camera products we carry, and the recorders that encode their data.
So what exactly is resolution, and further what is considered ‘high-resolution CCTV cameras”? Resolution is a number or numbers expressed to represent the total count of pixels within an image. This pixel count is directly correlated to the perceived visual quality of any image and referred to as the resolution.
Before digital pixels, quality was previously measured in TVL, also known as Tv Lines. TV from before the advent of digital broadcast and HD was broadcast in 360, or 480 TVL comparable to today’s 360, and 480p. Now that we’re in the digital age, all quality is measured in resolution. HD is a term that means high definition, another way of saying a large pixel count or a high resolution.
In reference to high-resolution CCTV Cameras, this is an umbrella term for a wide array of quality options. As we mentioned earlier, TV used to be the only 480p, but nowadays the standard TV broadcast is actually 720p or standard HD. As time went on, even more, high-resolution options became available. The older options were redesignated as ‘standard definition’ and the new emerging 720p (1280×720) was “high definition or HD”. Since then, even more, high-definition resolutions have become standard. These high-resolution CCTV equipment options include cameras and recorders that can handle Full HD aka 1080p, all the way up to 4k also known as 2160p or Ultra-HD. Anything 720p or up is considered HD. So that means HD CCTV cameras are any CCTV cameras that can do 720p or better image quality.
Today, even 720p has fallen to the wayside in favor of high resolution CCTV equipment like 4 Megapixels and 4k cameras. 4 Megapixels and 5 Megapixels are great intermediary choices that will net you a bit more HDD space than 4k, but still a great quality image!
