Benefits
he increased image resolution in HDTV/megapixel network cameras offer a number of benefits compared to other solutions.
Details Every detail matters could play an important role when event happening.
With a HDTV or megapixel network camera, the resolution is at least three times better than an analog CCTV camera.
It boils down to a simple truth: HDTV and megapixel means higher resolution. Higher resolution means more detail. More detail means better possibilities for identification. In addition, a true HDTV network camera provides full frame rate and extended color fidelity, for an even better viewing experience.

Wide Same number of cameras – more coverage
Another argument in favor of HDTV and megapixel network cameras is that they can cover larger scenes than non-megapixel network cameras at a given number of pixels per area.
For example, if four non-megapixel network cameras provide good coverage of your monitored scene, one 2.0 megapixel network camera will cover an even larger area, with no loss of image resolution.

More Different aspect ratios for more efficient surveillance
Network video enables images to be delivered in different aspect ratios, which especially advantageous in combination with the high resolution that megapixel network cameras offer. In a conventional TV monitor, an aspect ratio of 4:3 is provided. Network video can offer the same ratio, in addition to others, such as 16:9. For HDTV network cameras specifically, to comply with the SMPTE (Society of Motion Picture and Television Engineers) HDTV standards, the cameras are required to deliver 16:9 aspect ratio in full frame rate 30/25.
The advantage of 16:9 aspect ratio is that unimportant details, usually located in the upper and lower part of a conventional-sized image, are not present and do not take up bandwidth and storage space.

Weighing the pros and cons
Although megapixel network camera was superior in image resolution ratio, it have some potential technique defects at present. For example, because of engineer and cost, each pixel in which is small, that is to say, light sensitive of megapixel network cameras is not good as generals.
Different industry segments put different requirements on video surveillance solutions, but one shared challenge is getting enough image quality to ensure reliable identification of people and objects. HDTV and megapixel network cameras are used in a number of key industry segments to solve this challenge.
