what is difference between hd and full hd

Contrast this to an Arecont 3MP H.264 which sells on the Internet for less than $900 and probably MSRPs at no greater than $1100. So far the 1080p HD cameras are being priced at a significant premium to traditional 3MP cameras. Of course, it's just trade shows but it's reasonable to assume that not all companies who market HD cameras are going to produce the same quality. By contrast, I saw the Cisco 1080p HD camera at ASIS and it looked like a webcam. For instance, I saw the Axis HD camera at Intersec and the image quality was beautiful. The aspect that concerns me the most about HDTV marketing is the implicit claims to HD TV quality. Only in circumstances where very fast tiny movements are key will HDTV make a difference. A 12 frame per second camera provides an image every 83 milliseconds A 30 frame per second camera every 33 milliseconds. On the other hand, there will be certain applications (like casinos or money counting) where milliseconds count. While a lot of attention will be drawn to 'full frame rate', the reality is surveillance applications have traditionally used far fewer frames per second and been successful at doing. Most applications are fine with 12 frames or less, which is quite typical for 3MP cameras. This site is protected by reCAPTCHA and the Google Privacy Policy and Terms of Service apply.

HDTV has quality compliance standards (where megapixel simply specifies the number of pixels).

HD frame rate is 30/25 (where megapixel cameras are often 3 - 15 frames).

HD aspect ratio is 16:9 (compared to 5:4 or 4:3 in other surveillance cameras).

HD video format is 1280 x 720 or 1920 x 1080 (megapixel cameras can offer many more formats).

Maximum HD resolution is 2.1MP, maximum megapixel resolution is 20MP or more with 5MP cameras are common from numerous vendors.

The key features of HD for video surveillance is: HD's Key Features Compared to Typical Megapixel While standard definition cameras (e.g., analog cameras and 4CIF IP cameras) have no more than 400,000 pixels, all megapixel cameras (including HD) have 1,000,000 or more pixels.

All HD cameras are megapixel but not all megapixel cameras are HD. Indeed, Axis emphasizes HD, rather than megapixel in its marketing, causing many to ask what is the difference and which is better? However, in the last 6 months, a number of manufacturers have begun touting their new megapixel cameras as HD. Historically, everyone who sold cameras with 1 million pixels or more called them megapixel cameras. While 2009 was the year of megapixel surveillance cameras, it was also the year where confusion between HD and megapixel cameras began.
