The Buyer’s Guide to Megapixel Cameras for Surveillance
Surveillance cameras are now a necessity. While it was customary for many
commercial premises to have them as part of the safety measures, they are now
being looked upon as a critical factor in safety worldwide. As such, even
independent homeowners are now adding an extra layer of protection by investing
in surveillance cameras and security systems. This is exactly why you should know
which camera to buy and why the right megapixels matter.
The single biggest advantage why you should invest in good megapixel cameras is
resolution! It's the finer details that a camera captures that makes all the difference.
Since digital images are made of pixels, the megapixels of a camera will decide the
clarity of images.
While you may buy a 1MP or 2MP camera too, it's quite common to have 5MP
cameras and more depending on your surveillance needs. A lower megapixel
camera is just fine if you need to know the general condition of a particular location.
However, if you need to gather information about people, vehicles and other details,
it is important to have a high megapixel IP camera. In fact, an analog PTZ camera
would be your best bet if you are looking for surveillance of large areas where there
is lot of movement and data needs to be accurate.
They are high-sensitivity cameras with better zoom capabilities. Also, the pan, tilt
and zoom features ensure better images and therefore accurate information for
your surveillance needs. These cameras are also used in video conferencing,
television studios, sporting events etc. due to their versatility and precision. The
dome cameras are becoming very popular in the security and surveillance arena
and some of the advantages they offer over others include smooth movement, low
noise, and high sensitivity.
There are just too many cameras available today, endowed with the best features
and designs. Choosing one for your needs can be a daunting task unless you have a
fair knowledge about cameras. Make sure that you consult an expert before
investing in a top-end megapixel camera.
