Mega-pixel Digital HD Systems

Mega-pixel Digital HD Systems

So what is mega-pixel? A megapixel (MP) is a million pixels; the term is used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays.

What that means to you

Mega-pixel digital CCTV systems are efficient but the main benefit to you is a very noticeable leap in picture quality, much like the difference between watching a DVD movie compared to a blue-ray movie. Once you have experienced quality brand name HD security cameras it is hard to go back.

Quality is the key when choosing a camera system. You are unlikely to get advanced picture quality with a cheap brand system yet ironically that's exactly what you are paying for. These inferior systems are often the cause of constant network problems which are compounded even further when installed by people who do not understand the latest technology.


So if you are considering HD over an analogue security camera system, be prepared to pay more for a reputable brand and have it installed by a professional. It can save you a considerable amount of time, money and frustration in the long term.


What is mega-pixel IP? IP security cameras use a standard network to transmit data directly in digital format over existing or new network infrastructure, or alternatively over a wireless network without the need to decode and convert between analogue and digital. This makes them very efficient and capable of amazingly high resolutions.

IP Pros

  • The picture quality is significantly better than analogue
  • Generally IP systems have many more advanced features
  • IP systems are better for remote view with P2P
  • Search features are normally better
  • Facial and numberplate recognition are available
  • Easier integration with POS and other infrastructure
  • People monitoring technology is available

IP Cons

  • IP security cameras and recorders are more expensive
  • Some brands are riddled with counterfeit copies
  • They require a slightly more IT competent operator
  • They represent a higher risk as many installers simply don't understand the technology and can damage your network
  • IP camera systems can sometimes require stronger support from the supplier


What is mega-pixel TVI, CVI or AHD? All of these technologies provide cost effective Full HD images and are all quite similar. For many small businesses it makes little or no difference, however there are some points worth knowing.

  • CVI format is owned by a particular camera manufacturer so all CVI sales and availability world wide are controlled by a single company
  • AHD is open source and has no control, however as it is open source a lot of small manufacturers use AHD so quality can be an issue
  • TVI was developed by a chip company and given to the industry, most big brands use TVI as the preferred format



  • The picture quality is significantly better than analogue
  • Generally these systems are stable and easy to use
  • These systems are better for remote view via P2P
  • These systems are great value for money
  • Can be used when upgrading from analogue as they use the same cable


  • HD security cameras and recorders are more expensive than analogue
  • It's quite hard to know if it is a quality product as many are not branded or cheap quality
  • Some brands are riddled with counterfeit copies particularly CVI


What is mega-pixel HD-SDI? HD-SDI can produce quality pictures, however due to the high cost of manufacturing this tech is becoming less used by the industry and will eventually have no replacement parts readily available.
