Multi-Sensor Megapixel Cameras Redefine Camera Density Requirements

Surveillance systems which cover the extent of your facility are crucial in order to protect your assets and provide extremely important business data. Cameras are the foundation of any surveillance system and for the highest functionality it is important to provide the most camera coverage that is possible. This however, doesn’t require a higher camera count. It is important to consider the value of each individual camera and performance which it delivers, when looking at the density requirements of your camera installation. Businesses require security systems which perform to the highest of standards, therefore these cameras must have the resolution which would recognise faces and license plates, read numbers well and observe customer activity. Standard cameras provide 300,000 pixels per camera, while megapixel cameras provide atleast 1.3 million pixels per camera. Multi-sensor cameras have the ability to provide up to about 16 million pixels by combining several imaging sensors, therefore they can cover a greater distance while delivering higher performance and more capability, requiring lower camera densities to be built into the systems.

Megapixel cameras are a lot more advanced in capturing important information than standard resolution cameras, as they provide more pixels in their images and they can be adjusted to provide high ppf in order to support stronger identification or adjusted to cover larger viewing areas than standard cameras which have lower resolutions. Megapixel cameras can provide more functionality and they come in a multitude of form factors which cover a wide variety of surveillance needs. Megapixel cameras with the ability to maintain resolution and coverage while zooming into specific area can have a heavier burden than standard cameras. For example, in order to cover a parking lot which may require 10 standard cameras, you can use 3 or 4 megapixel cameras instead.

Megapixel cameras deliver higher operational performance than standard cameras, as an example, recent advances in low light performance and wide dynamic range allow cameras to capture improved images even in poor lighting conditions. Some leading manufacturers have cameras which can capture colour images down to 0.005 lux, allowing you to install cameras without IR illuminators or other expensive options for low light areas and times. With megapixel cameras you would have higher quality images which would allow you to reduce your camera density significantly.

Systems with many standard cameras would incur more installation and maintenance costs than a system covered by fewer, higher performing cameras. You would require more time to install the larger number of cameras and wiring runs to connect all of the cameras to the network, and you would also have to ensure to consider maintenance costs, as a denser cctv system would come with a higher probability of issues with each camera, which would require costly downtime while the issues would be dealt with and repaired. Lower density systems covered by megapixel cameras are more cost effective to install and maintain over the lifespan of the system.

You would require more powerful cameras which deliver the coverage and picture quality you require, in order to achieve the cost benefits of lower camera density on your surveillance system.

Since megapixel cameras have higher resolution and performance, they would allow you to cover a larger area with fewer amount of cameras and lower installation and maintenance costs. If you have a system with lower camera density and higher performance, it would become simpler and more cost effective to use and maintain.
