Understanding Megapixel and HD Security Cameras

Have you heard of an instance where an organization has all their cameras hacked at once? This indicates that there has been a security breach. Security systems are a popular means for securing our lives and are made up of various components. A camera is one such major component and is available in various types. IP cameras are a popular choice and are further divided into HD cameras and Megapixel cameras. To a common man, they are the same, but it is not so. This article can help you understand the difference between the two.

Megapixel Camera

A megapixel is defined as a camera with a resolution on the higher side of 1,000,000 pixels. It can capture images in various image formats (e.g. 4:3, 5:4 etc.) and various resolutions (1 to 10 megapixels +); the maximum resolution available currently is 29 megapixels. Its frame rate varies from 3 to 15 frames per second

Megapixel cameras have been evolving to accommodate the requirements of various new apps that keep being developed.

HD Camera

This type of camera is defined by a fixed resolution, frame rate aspect ratios. These are available in two resolutions:

  • HD (720p): The image for this camera is of 1280 x 720 pixels, which amounts to 921,600 pixels. Hence, this camera is not a megapixel camera.
  • Full HD (10180p): The images for this camera are of 1920 x 1080 pixels, which is 2.1 megapixels putting it into the category of megapixel cameras.

The image format is 16:9 image format and not 5:4 or 4:3. The frame rate is fixed at 25/30 Hz and each frame has all the lines drawn in a sequence. HD cameras are better for multimedia systems but are limited by resolution and format choices.

The differences simplified, both types are beneficial for business owners. How? Let’s see:

Benefits for the Business Owners

With these cameras, larger distances can be covered using fewer cameras, while still getting highly detailed images and live recordings. A lower number of cameras results in reduced requirements for infrastructure and lesser cabling costs.

If these cameras are positioned strategically and used wisely, you will be able to get better results from security systems at a much better cost

Simply put:All Megapixel cameras are High Definition cameras, but not all High Definition cameras are Megapixel cameras.” But, both can deliver better results while keeping the entire system cost effective.
