Demand for megapixel cameras is increasing in surveillance field and that’s due to the fact that these cameras have the potential to replace a number of legacy cameras at measurable product and installation cost savings.
The prime benefit of deploying Mega pixel cameras is that it offers security staff to digitally zoom in on specific details of images. And, in growing numbers, video evidence adds value to business and operation needs beyond security and life safety.
Going with the technicality, a pixel is one dot of info in a digital image, which can be made up of millions of tiny dots. A 10 MP image, for instance contains approximately 10 million pixels, while an 18 MP image contains 18 million pixels. Adding more pixels sometimes captures evidence at a lower quality, especially when data is being processed to be shown on hd screen.
Mega pixel security cameras in bigger installations can provide additional business benefits. For example, a 29 MP camera can provide the coverage area of more than 95 traditional VGA cameras or can also replace fifteen 2MP cameras, according to some manufacture’s marketing claims.
The most common megapixel resolutions are one megapixel and two megapixels and the difference is that 1080p cameras have two times the resolution-pixels- as compared to 720p. A 1080p has 1920×1080 resolution or 2.07 Megapixel. A 720p camera resolution has a resolution of 1280 x720 or 1 MP. Here the point to be noted is that 1080 is divided into two types where 1080i video is interlaced and contributes to a sense of motion and reduces perceived flicker. 1080P video is called progressive scan and makes images look sharper and more defined.
In 1 and 2 MP security camera installations, a full frame rate of 30 frames per second(fps) is standard. But as it needs higher bandwidth to transfer data, installers restrict the FPS to 12 or 15.
When it comes to management and security part, MP cameras offer the benefit of pinpointing any suspicious or violent activity when installed in a premises or large coverage areas like stadiums. They help law enforcement forces to respond in a matter of seconds. Sometimes they also offer the scope of being proactive, rather than being reactive- with the help of facial recognition with which security personnel can keep some people at bay.
But to get the best out of the MP cameras, enterprises or individuals should also focus on infrastructure and storage. Modern HD IP video surveillance cameras generate massive amounts of critical and sensitive data. Therefore, capturing, protecting and mobilizing this data turns crucial which cannot be done with traditional IT infrastructure.
So, all those who are planning to install MP cameras in their premises for security surveillance purposes should also focus on using high capacity video storage appliances supported by sufficient network bandwidth.
DNF Security offers video storage appliances which can be integrated by the same company’s cloud storage. This helps users to retain hot or frequently accessed data on the appliance and move all other archives to DNF Cloud Connection. This cuts down the need to purchase additional appliance or resources to storage archives useful for data retention purposes.
