Security Camera Resolution - Megapixel vs Analog
Ever since its advent, the video resolution and
quality of analog CCTV cameras has been limited. It gives blur images which are
hardly helpful when investigating something. But things are changing rapidly
now. Within the last few years, megapixel cameras have started appearing in the
market as a popular choice for security systems. Though the price difference
between the two is huge, we will try to explain why it is justified.
As the name ‘megapixel camera’ suggests, the
most significant difference between megapixel and analog cameras is resolution.
The 1.2MP camera gives you 3.5 times better resolution than the best analog
camera (D1). Better resolution gives the images more detail and color clarity
enabling you to capture important elements of a situation, such as a person's
tattoo or a license plate.
The high resolution images captured using the
Megapixel camera also provide the ability to enlarge or zoom portions of the
image without pixelation and distortion (honestly, it will be there but not to
the same degree as you would get with images taken with an Analog camera). This
allows you to perform post-processing on images, to read further detail from a
given scene. This is a significant improvement over the traditional analog
cameras and will lead towards a more secure environment.
Moreover, most megapixel cameras are network
cameras, giving you a variety of added benefits over analog cameras. IP cameras
have many options like PoE (which allows you to run power and video over one
Ethernet cable), wireless capabilities, and network storage (which means no
need for a DVR!), not to mention you can view these cameras from anywhere in
the world with just a few network settings. All of these features in at a
slightly more cost than its analog counterpart keep the megapixel camera on top
of the surveillance food chain.
